PIPING SYSTEM

1. BASICS OF PIPING SYSTEM

3. What is a Piping System piping  is a  system  of pipes used to convey fluids (liquids and gases) from one location to another .

4. Components of Piping System

5. Pipe Pipe is a hollow tube with round cross section for the conveyance of products. The products include fluids, gas, pellets, powders and more.

6. Nomenclature Nominal Pipe Size : Nominal pipe size ( NPS ) is a dimensionless designator of pipe size. It indicates standard pipe size when followed by the specific size designation number without an inch symbol. For example, NPS 6 indicates a pipe whose outside diameter is 168.3 mm . Schedule Number: For a given NPS, the outside diameter stays constant and the wall thickness increases with larger schedule number. The inside diameter will depend upon the pipe wall thickness specified by the schedule number . Schedule Number = 1,000 x (P/S) where P = internal pressure, pounds-per-square-inch-gauge ( psig) S = allowable fiber stress (ultimate  tensile  strength of the steel in psi)

8. Type of Pipes LONGITUDINALLY WELDED SAW ELECTRIC RESISTANCE WELDED (ERW) SEAMLESS

9. Flange A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.

10. Types of Flanges : Welded Neck, Slip On 1 . Slip On flange  2 . Filled weld outside 3 . Filled weld inside  4 . Pipe 1 . Weld Neck flange  2 . Butt Weld 3 . Pipe or Fitting

11. Socket Welded and Lap Joint Flange 1 . Socket Weld flange  2 . Filled weld  3 . Pipe X  = Expansion gap 1 . Lap Joint flange  2 . Stub End 3 . Butt weld  4 . Pipe or Fitting

12. Threaded AND Blind Flange 1 . Threaded flange  2 . Thread  3 . Pipe or Fitting 1 . Blind flange  2 . Stud Bolt  3 . Gasket  4 . Other flange

13. Gaskets Flange gaskets are used to create a static seal between two flanges faces A gaskets fills the microscopic spaces and irregularities of the flange faces, and then it forms a seal that is designed to keep liquids and gases

14. Semi Metallic SEMI-METALLIC GASKETS  are composites of metal and non-metallic materials. The metal is intended to offer strength and resiliency, while the non-metallic portion provides conformability and sealability . Semi-metallic are designed for almost all operating conditions and high-temperature and pressure.

15. Non Metallic NON-METALLIC GASKETS  are usually composite sheet materials are used with flat-face and raised-face flanges in low Pressure Class applications . Non-metallic gaskets are manufactured from arimid fiber, glass fiber, elastomer, Teflon® (PTFE), graphite etc.

16. Fasteners ASME B1.1, included angle is 60° ASME B18.2.2,

17. Gasket Nomenclature

18. Expansion Joints Metallic Expansion Joints are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces.

19. Reducers and T-Joints

20. Assembly Fasteners and Flange

21. Material of Construction 316 stainless has a unique chemical composition which includes 16% chromium, 10% nickel and 2% molybdenum 304 stainless has 18% chromium, 8% nickel and no molybdenum   Stainless steel certified to 316L or 304L will have a maximum of 0.03% carbon, versus the 0.08% maximum that regular 316 and 304 can have.
