Editor's Notes
- Good morning!!! Welcome to Pipe Shields pre-insulated support webinar. First of all I want to thank you all for taking the time to attend his webinar.
- I am currently the General Manager of Pipe Shields Inc. I started my career as a designer in manufacturing in San Francisco, at a company called Kinnear which made industrial roll-up doors. I moved into the nuclear industry as a design engineer at Impel Corporation, where I worked for 10 years. That’s where I got into piping systems and pipe supports. After that, I joined Pipe Shields in 1991 (about 23 years ago when there was about 120 people who worked there. I started out as a design engineer, became an engineering manager, which eventually led me to becoming the general manager of Pipe Shields.
- Overview of my presentation this morning….
- In business since 1975, Piping Technology & Products, Inc. and its wholly owned subsidiaries (U.S. Bellows, Inc., Sweco Fab, Inc., Pipe Shields, Inc., and Anchor Darling, Enterprises, Inc.) offer a wide range of engineered products and services for various industries and applications. From engineered pipe supports, expansion joints, pre-insulated pipe supports, and miscellaneous fabrication to various engineering and technical services, PT&P has decades of experience providing products and services for all your engineering and construction needs. Based in Houston, TX on a 35 acre property which is located near the Port of Houston for convenient shipping from around the world. PT&P strives to satisfy each customer's request from custom designed and engineered products to emergency situations in need of critical and time restricted attention. PT&P also continues to search for ways to increase customer satisfaction and quality. Through our value-added services such as our 24x7 Field Services, product testing, piping stress analysis, and engineering & design services, PT&P is able to support our customers above and beyond expectations
- Pipe Shields Inc.is one of the world’s leading designers and manufacturers of a unique line of pre-insulated pipe supports, slides, guides and anchors that it has developed and patented during its 40 year history. Pipe Shields' highly sophisticated products are a direct result of years of research, engineering and design to develop cost efficient products for the power, petrochemical, chemical and commercial markets. Pipe Shields, Inc. was acquired from the Shaw Group Inc. in August 2004 by Piping Technology & Products, Inc.. Sales and Engineering office is located in Fairfield, CA. Manufacturing located in Houston, TX
- Pipe Shields, Inc. designs and manufactures a complete line of pre-insulated pipe supports for commercial, light industrial and heavy industrial facilities. For all types and sizes of piping materials, including, but not limited to: carbon steel pipes, stainless steel pipe, alloy pipes, plastics pipes and more.
- So what do you consider a commercial , light or heavy industrial facility? A commercial facility might be a multi-story building where pre-insulated supports are used to insulate and support the heating water and cooling water. A light industrial facility could be an airport or hospital where again supports are used for heating water, cooling water and also could be used for some low pressure steam lines. Finally, we have heavy industrial facilities which would include power plants, major manufacturing facilities, petrochemical plants, chemical plants, etc. For commercial and light industrial facilities, our customer is typically a mechanical contractor. A mechanical contractor works for the company hired by the general contractor (the company ahead of the whole project) to design, procure and install all the piping systems in the facility/building in question. Some mechanical contractors that we do business with include ACCO Engineered Systems, Harder Mechanical, Charter Mechanical, Cobb Mechanical, etc. For heavy industrial applications, our customer is typically an engineering and procurement construction (EPC), an A&E (architect engineers) or General Contractors. Customers here are companies like Bechtel, Jacobs, Fluor, M+W Group, CB&I, etc.
- A pre-insulated support, which we also call a pipe shield, consists of a particular type of insulation material, a protective shield and has a mechanism such as a clevis hanger, roller or base mount to support the pipe. All insulated pipes shall be supported with pre-insulated pipe supports. Pre-Insulated pipe supports shall comply with the following standards: A. ANSI/ASME B31.1 & B31.3 B. Manufacturers Standardization Society SP-58, 69, & 89. These standards establish the material, design, fabrication and inspection criteria for the proper selection, manufacture, and installation of pipe hangers and supports.
- In many chemical plants, refineries and LNG facilities, there are processes where the “product or medium” inside the piping is at very cold or very hot temperatures. In these applications, there exists the need to both support and insulate the pipeline while simultaneously allowing and/or limiting the pipe movement. The ability to adequately insulate the pipeline helps to increase the efficiency of the piping system by not allowing the “cold” or “hot” temperature inside the pipe to transfer between supporting elements and the surrounding environment. Thus, they reduce temperature loss due to conduction at each support. All pre- insulated supports have the same functions: to both support and insulate the piping.
- It is still common to see one of the earliest methods used to support cold pipelines in plants today. These first types of cold supports utilized wood, usually oak as the preferred insulation. The oak would be cut to match the curvature of the pipe and be placed beneath the pipe. A steel cradle or other type of support component could then be placed beneath the insulation wood. The conventional method of supporting an insulated pipe is when you clamp directly on the pipe and then you insulate around the clamp similar to the middle picture shown. With pre-insulated supports, we support the line by clamping around the insulation using a proprietary insulation material to support the load AND insulate the line. Hence, there is no metal-to-metal contact at all.
- Why is this better than the conventional method? Can save you money on your bid and on the job, by lowering your material costs, as well as your labor costs. Saves Labor No special welding (by a certified welder) is required in the field (save labor) No pre-heat or post-heat weld treatment (save labor) No weld x-ray inspection report (save labor) Reduced Risk of Failure Compared to Welded Supports Insulation contractor never touches the pipe hanger… they only have to make a butt joint between the pipe insulation and the insulated support. Mechanical contractor does not have to return for expensive, final adjustment. No temperature/energy loss in the system because there is no metal to metal contact (so no energy is lost due to conduction) No special (ie expensive) alloy material is required (save material) Increase support spacing, because insulated supports can have a higher load rating (we custom design the support to carry greater load – increase the insulation insert and steel width). This means you can reduce the number of supports required on a job (fewer supports = less cost). Energy efficient – since there is no metal to metal contact, the temperature on the pipe is pretty much maintained and therefore there is no significant loss of heat or cold temperature on the pipeline. Innovative Design and Quality Features Quick Installation and Alignment
- You pick the right pre-insulated pipe support based on the piping temperature, loads and movements. Commercial Calculate the load on the supports by adding up: Weight of the pipe Weight of the medium in the pipe (often, water) Weight of the pipe insulation Any valves or other equipment Movements are considered negligible where temperatures are low ( ie 120 degrees F or below) Industrial (light or heavy) loads and movements will typically be calculated using pipe stress analysis software, such as Caesar or CAE Pipe.
- Here are some typical pre-insulated support schemes to consider when selecting the pre-insulated pipe supports: Hanging- Clevis hanger or 2 bolt clamp – used when there is no building steel available to support the pipe from below, or there could be some equipment or interference below the pipe. Base mounted- On a flat surface, which is used when there is available steel readily available below the pipe, and there is no space or steel to support the pipe from above. On a roller(s) – used when large axial or longitudinal pipe movements are expected.
- The protective shield is often made from galvanized sheet metal and is placed around the insulation material. It is used to protect the insulation during installation of the support. After installation, the shield is used to protect the insulation material from external sources that might damage it.
- Once you have these inputs the first thing you have to do is select an insulation material for the pre-insulated pipe support. Normally, your piping designer will have already selected a pipe insulation to wrap the pipe with so you will need to pick the same material to match. Generally, for hot applications, the insulation material used is calcium silicate. There are exceptions to this where you might use pyro gel or mineral wool. Even in these cases, the recommended material is still calcium silicate, especially when the pipe loads are very high. The pyro gel or mineral wool has a very low compressive strength allowable, compared to calcium silicate, which comes in a higher range of densities and therefore higher compressive strengths. Calcium silicate is good from 40 degreesF to 1800 degreesF. Some examples of where you might use calcium silicate is on a main line in a styrene plant, steam lines on a power or process plants, and even hot water lines. What is calcium silicate? A combination of a silica material (ie a sand) mixed with solid calcium. We use it in insulated pipe supports for it’s insulating properties and it’s higher compressive strength. For cold applications, ie anything below 40 degrees F up to -275 degrees F, we normally use polyurethane material. It is the same material that is used on running tracks, but the variety we manufacture is a much higher density. Again, like the calcium silicate, we use this material for both it’s insulating properties and it’s load carrying capacity. Polyurethane is a polymer formed by the combination of polyol and isocyanate. ---- So now we’ve picked the right material for the job… Now we go to our Pipe Shields catalog to find the right design for your application.
- Depending on the type of service or medium that is in the pipe, our selection guide tables can be used to select the most appropriate type of Pipe Shields model for your application. First you determine what service the system will be providing (water, steam, gas or air) and then the other two major considerations are: if the pipe is supported from above or if the pipe is supported from below. Once you have determined those factors, the selection guide will guide you to another table that becomes more detailed and specific to your situation
- Here is an example of how to use the selection guide table in determining the most appropriate Pipe Shields model for your application: A1000 vs. A2000 and A3000 vs. A4000 Commercial A2000 and A4000 is more optimized for cold application (has lip that exposes insulation that works better with the insulation adhesive). A1000 works for hot or cold application. A1000/A2000 vs. A3000/A4000 (as a group) A3000/A4000 has a slightly higher spacing ability A9000 Much Higher load capacity, because of an added proprietary high density structural inserts that is placed within the assembly. Greater spacing In all of Pipe Shields A series supports the Clevis hangers/rollers/strut clamp/strut channel are not included! D1000 vs. D2000 and D4000 vs. D5000 D2000 and D5000 are more optimized for cold application (has lip that exposes insulation that works better with insulation adhesive). D1000/D2000 vs. D4000/D5000: 1 rod hanging (D1000/D2000 vertical clamp) vs. 2 rod hanging (D4000/D5000 horizontal clamp) D3000 vs. D6000: 1 rod hanging ( D3000 vertical clamp) vs. 2 rod hanging ( D6000 horizontal clamp) D3000 D3100 D3200 D3300: can support heavier and heavier loads and spacing increases.
- For smaller loads and movement piping systems(Usually commercial or light industrial), commonly used on chilled and heated water systems. Pipe sizes ranging from 1/2" up to 42". Most popular with mechanical contractors. Could be used on a flat surface, roll, or by hanging from somewhere. A1000 vs. A2000 (and A3000 vs. A4000) A2000 is more optimized for cold application (has lip that exposes insulation that works better with the insulation adhesive). A1000 works for hot or cold application. A1000/A2000 vs. A3000/A4000 latter has a slightly higher spacing ability A9000 higher loads, greater spacing Water proofed insulation 360º around. Spring loaded jacket forms natural vapor barrier, no condensation. More than 13 catalog designs available. Installs on flat, band, ring or clevis hangers.
- Commonly used in heavy Industrial and large HVAC distribution systems For larger loads (vertical and lateral) and movements. Supports the pipe from below (base-mounted) Slide plates and guides included
- Used in heavy industrial and large HVAC applications. For larger multi-directional loads and movements. Supports the pipe from below. Restrains all movements of the piping system. Heavy industrial for anchoring applications (ie three directional loads) C3000s vs. C4000s: C3000s rely on friction force (between pipe and insulation insert), C4000 use a more “positive” anchoring mechanism– ie an inner thrust plate welded onto the pipe.
- For larger loads and movements. Supports the pipe from above (with one or two hanging rods). Used in heavy industrial and large HVAC applications. D1000 vs. D2000 (and D4000 vs. D5000) D2000 and D5000 are more optimized for cold application (has lip that exposes insulation that works better with insulation adhesive). D1000/D2000 vs. D4000/D5000: 1 rod hanging (D1000/D2000 vertical clamp) vs. 2 rod hanging (D4000/D5000 horizontal clamp) D3000 vs. D6000: 1 rod hanging (D3000 vertical clamp) vs. 2 rod hanging (D6000 horizontal clamp) D3000 D3100 D3200 D3300: can support heavier and heavier loads and spacing increases. Designed to take advantage of maximum hanger spacing. Two bolt hanger type for 1/2”-60” pipe. Double rod hanger design supports 1/2”-60” pipe. Accommodates minimum overhead clearances.
- For both smaller and larger loads and movements. Supports the pipe in a vertical or "riser" configuration. For commercial, light, and heavy industrial and large HVAC distribution systems. Vertical/riser pipes Designs available to restrain both upward and downward loads. Requires field welding of factory supplied thrust plates on the upper or upper and lower sides of the clamp, depending on the load direction.
- Miscellaneous pipe clamping hardware. Typically used in conjunction with Pipe Shields A1000 through A9000 series insulated supports. Accompanying hardware for A-series– Strut clamp, U-Bolt,
- After all the selection process have been completely and accurately determined, the appropriate model selected which is purchased by the buyer is then process through our order entry group and all necessary paperwork and documentation are generated. Then the steel materials required are cut, formed and welded together as required per fabrication details and instructions. The proprietary insulation materials are then cut and assembled together with the formed steel cradle, then carefully packaged together and shipped. The unit arrives fully assembled in the field, then they are disassembled and reassembled during the installation on the pipe and the steel supports. Pipe Shields pre-insulated supports which comes with the polyurethane insulation for cold and cryogenic application, are actually poured and formed at the Houston fabrication facility. Then they are carefully cut and fitted to the steel cradle for accurate match and fit up.
- Pipe Shields has ample inventory of raw materials required for the fabrication of pre-insulated pipe supports. Since we pour our own polyurethane foam insulation, we have a controlled inventory of our insulation requirements.
- Installation is very easy and a time saver. Simply disassemble the unit. Place bottom half of the insulation insert under the pipe and slide in the top half of the insulation insert over the pipe and into the bottom half insulation insert. The top half of the insulation insert has an overlapping sheet metal jacket that will “interlock” with the bottom half insulation insert and thus keep the unit intact on the pipe. Then install the pipe hanger hardware (clevis or clamp) and attach to the rest of the hardware required to hang or support the pipe.
- Pre-insulated supports are very low maintenance products, except for the standard maintenance and inspection items that are needed on any pipe hanger system. This typically involves the following: Bolt torque requirements Rod hanger adjustments Inspect and touch-up materials for possible corrosion Inspect insulation material for possible major failures Inspect and clean polyethylene slide material
- Pipe Shields, Inc. can offer field services for the proper installation, inspection and periodic maintenance of our pre-insulated supports.
- The ISO 9001-2008 certifies us for manufacturing quality hot and cold pipe supports. It lets our customers know that we consistently meet and provide our customers with products that meet the applicable statutory and regulatory requirements.
