The document discusses piping systems, which consist of pipes used to convey fluids and are a critical aspect of piping design in engineering. It outlines the materials used for manufacturing pipes, standards for design and manufacturing, and emphasizes the importance of stress analysis for ensuring structural integrity. Additionally, it lists prominent pipe manufacturers in the UAE.

1. PIPE MANUFACTURING
AND TYPES

2. WHAT IS PIPING?
• piping is a system of pipes used to convey fluids (liquids and gases) from one
location to another. The engineering discipline of piping design studies the efficient
transport of fluid
• Industrial process piping (and accompanying in-line components) can be
manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper,
and concrete. The in-line components, known as fittings,[3] valves, and other devices,
typically sense and control the pressure, flow rate and temperature of the
transmitted fluid, and usually are included in the field of piping design (or piping
engineering). Piping systems are documented in piping and instrumentation
diagrams (P&IDs). If necessary, pipes can be cleaned by the tube cleaning process.

3. GENERALLY, INDUSTRIAL PIPING ENGINEERING HAS
THREE MAJOR SUBFIELDS:
• Piping material
• Piping design
• Stress analysis

4. STRESS ANALYSIS
• Process piping and power piping are typically checked by pipe stress engineers to
verify that the routing, nozzle loads, hangers, and supports are properly placed and
selected such that allowable pipe stress is not exceeded under different loads such
as sustained loads, operating loads, pressure testing loads, etc., as stipulated by
the ASME B31, EN 13480 or any other applicable codes and standards. It is
necessary to evaluate the mechanical behavior of the piping under regular loads
(internal pressure and thermal stresses) as well under occasional and intermittent
loading cases such as earthquake, high wind or special vibration, and water hammer.
This evaluation is usually performed with the assistance of a specialized (finite
element) pipe stress analysis computer programs such as CAEPIPEand CAESAR.
• In cryogenic pipe supports, most steel become more brittle as the temperature
decreases from normal operating conditions, so it is necessary to know the
temperature distribution for cryogenic conditions. Steel structures will have areas of
high stress that may be caused by sharp corners in the design, or inclusions in the
material.

5. MATERIALS
• The material with which a pipe is manufactured often forms as the basis for
choosing any pipe. Materials that are used for manufacturing pipes include:
1. Carbon steel
2. ASTM A252 Spec Grade 1, Grade 2, Grade 3 Steel Pile Pipe
3. Low temperature service carbon steel
4. Stainless steel
5. Nonferrous metals, e.g. cupro-nickel, tantalum lined, etc.
6. Nonmetallic, e.g. tempered glass, Teflon lined, PVC, etc.

6. STANDARDS
• There are certain standard codes that need to be followed while designing or
manufacturing any piping system. Organizations that promulgate piping standards
include:
• ASME - The American Society of Mechanical Engineers - B31 seriesASME B31.1
Power piping (steam piping etc.)
• ASME B31.3 Process piping
• ASME B31.4 Pipeline Transportation Systems for Liquid Hydrocarbons and Other
Liquids
• ASME B31.5 Refrigeration piping and heat transfer components
And further more.

7. THERE ARE THREE BASIC TYPES OF PLASTIC PIPES:
• Solid wall pipe
Extruded pipes consisting of one layer of a homogeneous matrix of thermoplastic
material which is ready for use in a pipeline
• Structured wall pipe
Structured-wall pipes and fittings are products which have an optimized design with
regard to material usage to achieve the physical, mechanical and performance
requirements. Structured Wall Pipes are tailor made solutions of piping systems, for a
variety of applications and in most cases developed in cooperation with users

8. CONT..
• Barrier pipe
• Pipe incorporating a flexible metallic layer as the middle of three bonded layers.
Barrier pipe is used, for example, to provide additional protection for the contents
passing through the pipe (particularly drinking water) from aggressive chemicals or
other pollution when laid in ground contaminated by previous use.
• Most plastic pipe systems are made from thermoplastic materials. The production
method involves melting the material, shaping and then cooling. Pipes are normally
produced by extrusion.
