SECTION 1: Suspension of Horizontal Line Schematic of a Pipeline Suspended Horizontally
Suspension of Horizontal Line: Standard Loads & Temperatures, Minimal Insulation Explain “Standard Design” vs. “Custom Design” for the purposes of this presentation Custom: 1. FRP piping, Ductile Iron Piping, Plastic Piping, etc. where the diameter differs from a standard pipe. 2. High temperature application or a different type of material (could be one in the same) maybe using stainless steel for high temperature where you do not want a cross contamination b/w carbon steel and stainless steel. 3. If load exceed standard clamp maximum loading capabilities. fig. 50 light 2-bolt pipe clamp fig. 60 heavy 2-bolt pipe clamps The standard (off-the-self) clamps which are manufactured on a daily basis. For us, a suspension of an un-insulated line can most readily be accomplished with the use of our standard 2-bolt pipe clamp. These are made of carbon steel with either an unfinished or a galvanized finish and they are usually used to support lines which have no insulation. Pipe sizes range from ½ " to 36 " with a maximum load rating for our standard figure 50 model clamp being 4,000 lb. on a 36 " clamp. In suspension of other pipes, we have figure 60, our heavy duty pipe clamp, which has a larger load rating, but the same configuration. But it is utilized for 3 " to 36 " lines with a maximum load rating of 28,000 lb. Once again these can be procured in either a unfinished condition where the client would specify a finish of painting or some other material or a hot-dipped galvanized finish.
Suspension of Horizontal Line (Standard Loads & Temperatures, Minimal Insulation) fig. 83 Adjustable Clevis Hanger Clevis type beam clamp assemblies. Standard product but can be manufactured to any special designs required. Use of beam type of clamp and a clevis type of clamp to suspend insulated lines wherein the insulation did not need to interfere with the clamp hanger assembly. This support assembly is designed to support a pipe that is 10 " in diameter and used to suspend loads of 3,600 lb. Nice ability of these clamps is that in conjunction with the beam clamp, we can have a swing which exceeds the standard 4 degrees recommended by MSS Standards. Original Notes Below The rod measures 7/8 " in diameter. The function of the beam clamp assembly is to support the pipe and allow it to swing. The clamp requires no welding which allows for a quick and easy installation. Carbon steel with a hot-dipped galvanized finish.

Suspension of Horizontal Line: Finite Element Analysis of Pipe Clamp FEA helps us to optimize materials, bolting and types of manufacture that we are using to optimize weight considerations and cost considerations. Here we are looking at two 24 " pipes with significantly different loads (Right: 33,500 lb. load and Left: 68,200 lb. load). Both will be used in high temperature service on grade 91 pipe, however because the loads are so different, it is more beneficial to use two different clamps (Right: with a load of 33,500 lb. we reduced the stock size to 1 ¼ " by 8 " ) (Left: because the load is 68,200 lb. the minimum stock size would be 2 " by 12 " ). FEA helped to optimize the clamps on an individual basis. Even though both clamps have the same pipe size and operating temperatures, the load constraint was the greatest factor determining the clamp and load bolt size. Original Notes Below FEA on Figure 80 heavy duty 3-bolt pipe clamp for a high temperature application. Due to the high temperature, the clamps are fabricated from alloy steel, A387 Grade 91. We analyzed two different pipes – one for a 68,200 lb. load and the other for a 33,500 lb. load. Conclusion: After the analyses, we found that the bending radius of forming the ears is 1.5 times the plate thickness. The AISC recommends that the values are 3 times the thickness of the plates of 1 to 1 ½ " thickness and 4 times the thickness for greater thicknesses. The FEA analyses demonstrate that larger radiuses would result in lower stresses. This conclusion has led to significantly lower costs to our customers by justifying the use of less steel.

Bottom: 66" 3-Bolt Pipe Clamp (500 ° F and operating load of 24,000 lb.) Original Notes Below Top picture here shows our figure 70A three-bolt pipe clamps custom designed for a power plant in Florida. 14-18 " clamps wherein the loads exceeded the maximum load rating of our standard clamps, we were looking to accomplish load ratings between 8,000 and 25,000 lb. where the standard maximum load rating is in the neighborhood of 4,000 lb. We needed to modify the clamp stock size either in thickness or width or both, as well as the bolt size which is necessary to hold up the specified load. This project included 30 clamps fabricated from SA 387 grade 22 alloy steel. These clamps are designed to suspend pipe lines where there is high temperature and great thermal movement. ( http://www.pipingtech.com/news/arc_pw_2004/sacs2004_08.htm) The bottom picture is a custom designed three-bolt pipe clamp made for 66 " duct work (for a chemical company). By using a FEA program, the clamp was designed for an suspension load of 24,000 lb 500°F. After formation, the clamps’ dimensions measured 97.75 " overall length and 69.5 " at its widest point.

Suspension of Horizontal Line (High Loads-70,000 lb., High Temperatures-exceeds 1050 ° F, Large Diameter-42 " and Insulation) 42 " Heavy Duty Alloy Yoke Clamp Now we will look at how we utilize Finite Element Analysis to help in the design of clamps. Here you see a special 42 " heavy duty alloy yoke clamp which was designed for a load excess of 70,000 lb. The Finite Element Analysis was first conducted to optimize the design and it showed making the yoke out of 6 " thick plate actually produced more loading inside the u-bolt than in the yolk section. The u-bolt was made out of a 3 " diameter bar and the yolk was made out of 6” fabricated chrome-molly steel. This was a high temperature application wherein the operating temperature exceeded 1,050 °F, and as a result, the clamp was made out of chrome-molly 387 grade 22. http://www.pipingtech.com/news/arc_pw_2001/sacs2001_02.htm
Suspension of Horizontal Line: Finite Element Analysis of Yoke Clamp Where complicated design configurations exist… Piping Technology & Products, Inc. has extensive in-house finite element analysis capabilities using ProEngineer, ANSYS, and a variety of other software packages. FEA software is used to simulate the loads and resulting stresses which a particular design might experience in the field. These time and money-saving computer simulations are used to select designs for prototypes. We later use these prototypes to test products with actual loads to confirm our design loads and safety features. FEA provides very realistic and accurate analysis of mechanical parts that undergo specified thermal and mechanical loads. Performing and FEA is time-effective and a cost-effective complement to physical testing -- following a preliminary finite analysis with a physical load test significantly reduces the design cycle time. Interpreting and understanding FEA's proves useful to explaining stress and strain conditions to customers in a highly visual manner. The use of FEA significantly improves PT&P's engineering, research, and design capabilities.

Suspension of Horizontal Line: High Loads & Temperatures and Insulation Custom 3-Bolt Pipe Clamp What makes a clamp a custom design, we see a clamp which is utilized for a 24 " outside diameter pipe. Stock size is large for this clamp being 9 " stock material. Different stock size than normal, different dimension from the center of the clamp to the load bolt. There are over 450 products, just like this one, featured in our Product of the Week Archives… located at pipingtech.com, in the “News” section. Original Notes Below This is a custom-designed 3-bolt clamp for a 765 MW natural gas-fired combined cycle facility. These clamps in conjunction with variable springs, will allow for vertical and axial pipe movement while restricting lateral movements. Based on design considerations, the clamp "E" dimension, from pipe centerline to outer load bolt, is 25 " . The clamps were designed for operation at 1,065°F and per customer-supplied information. The vertical design load is 1,848 lb. and the maximum lateral load is 19,207 lb. The clamp plates are made of A387 GR. 22 plate material. The stanchion pieces are made of A335 GR.22 pipe and the side stop plates are made of carbon steel. http://www.pipingtech.com/news/arc_pw_2002/sacs2002_03.htm
Restraint of Horizontal Line FEA of Pipe Clamp FEA helps to optimize the materials and helps to review what the clamp is doing to the pipe itself. In this case, the pipe was plastic and did not have great residual stresses induced by the clamp. In an effort to reduce that, we designed a clamp wherein the 2 center sections actually met instead of having a gap b/w them wherein field personnel or construction personnel might have to over torque the clamp to get them to come together. This clamp was designed with a zero gap such that when the clamp was tightened, the stress would be known at the pipe intersection. In this instance we were trying to overcome some axial force on the pipe but at the same time barely overcome that axial force such that an 8,000 lb. axial load would not induce anymore residual stresses longitudinally inside the pipe. Original Notes Below A stress analysis was conducted of an 8" plastic pipe constrained in the axial direction by a special pipe clamp. PT&P’s final design assumes that three clamps in a series will resist a total expected axial force of 8,000 lb. Since the area of the pipe in contact with the support affects the overall stress distribution, it is necessary to determine how much contact there is at different pressures via FEA in two steps. CONCLUSION: The maximum stress on the clamp is determined to be twenty-eight thousand PSI (28,000 PSI). Stresses in the figure on the right would normally be of little concern in mild steel at typical operating temperatures. If it were a problem, extending the gussets upwards is recommended. In addition, it is recommended to increase pipe length if higher stress is desired. This is due to increased contact between the pipe and clamp, which spreads stress over more area allowing for greater pressures.

SECTION 5: Special Conditions Special Conditions: Example 1 3 Fold Problem: 1.) We had a 97" duct work which is much greater than our standard clamp can withstand and 2.) interference problems in that the duct work had very close tolerances with the structure below it and 3.) the duct work was thin walled and any stresses induced on the duct by the clamp can be detrimental. In an effort to alleviate all 3 of those conditions, a 3-piece pipe clamp was made with a bottom cradle section, approx. 150 degrees and 2 upper load restraining sections which were used to suspend the load. The bottom section was made wider to distribute the load over the duct work at 18" wide while the upper sections were 12" wide. These clamps were designed to withstand a maximum loading of approx. 17,000 lb. and also to allow the duct work to receive as little residual stresses from the clamping structure as possible. This was a 3 pronged attack with eliminated the lower bolts on the bottom which allowed the clamp to be as close to the bottom section of the duct work as possible. Original Notes Below This is a custom design 3-piece pipe clamp used to support 97" diameter stainless steel duct work. The duct work is being added to a refinery for an expansion project in Ponco City, Oklahoma. Each section of the clamp assembly is formed from a continuous plate and gussets are added at each of the bolt locations for increased strength and rigidity. Due to the ducts having a relatively thin wall, these clamps are designed wider than necessary in an effort to reduce localized stresses on the duct work. The lower section of each clamp is formed to create a 150° cradle. This acts as a cradle by supporting the duct without inducing extra pressure, which might cause the duct wall to buckle or bend. The upper sections are formed from 1/2" thick by 12" wide bar stock, whereas the lower sections are formed from a 1/2" thick by 18" wide. All three sections are rolled to an inner radius of 48 1/2" and the welded gusset plates are all 1/2" thick. The upper sections are formed at 105° each, and the upper load bolt is 2" in diameter while the 6 clamping bolts are 1 1/2" in diameter. The maximum load to be carried by these pipe clamps is 16,888 lb. Each pipe clamp will be used in conjunction with a variable spring support to accommodate movements as high as 2 1/4".
Special Conditions: Example 2 Slightly different type of clamping configuration This is a custom clamp that will be used in conjunction with a hydraulic snubber to restrain the pipe movement during extremely high disturbances. (snubber utilized when a upset is found in the system) Snubber needed when a 68,000 lb. upset load occurred within the system. 2 lower links joined together by an upper yoke assembly. The distance between the links is used to accommodate the pipe size, which in this instance was a 4" pipe with a 4 ½" diameter. As a result the lower links can be slipped over the pipe and then slid down the pipe until they came to a connection where 2 flanges with the approximate diameter of 10" were used. This allowed us to use not only the strongest portion of the pipe for suspension, but also allowed us to not induce a great deal of stress on the 4" section of pipe. In this instance the 68,000 lb. load would be held at two flange connections instead of being induced onto the pipe. In an effort to sustain that load, you can see the top load bolt is 2 ¼" in diameter cause at the time of this disturbance upset loading, this would be taking the entire load induced onto the snubber. Original Notes Below The outer diameter of the clamp section is 16", and the inner diameter is 10" The yoke, lugs, and strap sections of the clamp are carbon steel, and the clamp bolts and load bolt/pin are stainless steel. The upper lugs are fabricated from 3/4" thick plate
Special Conditions: Example 3 These custom riser clamp assemblies are designed with neoprene lining and will be used on an oil rig in the Gulf of Mexico They are fabricated from carbon steel and will support vertical pipe lines Each assembly consists of two clamps and a clamp stand Several coats of marine paint finish were applied to prevent corrosion due to salt water content and open air exposure
