What are the piping codes?
Piping codes define the requirements of engineering, design, fabrication, use of materials, tests and inspection of pipes and piping systems. Each code has a limited jurisdiction defined by the scope of the code.
What is the name of pipe special fitting?
5.10). When two ends of pipes are joined, the pipe fitting used is called union. A union is made of three parts namely a nut, a male end and a female end. The male and female ends are assembled with the support of the nuts, and necessary pressure is made to connect the joint.
How do you connect a small pipe to a big pipe?
Coupling & Adapter Fittings – Pipe couplers slip over the outside of two pipes to connect them, usually permanently. A coupling can be a reducer, or reducing coupling, meaning they reduce flow by joining a larger pipe to a smaller size. Adapters are used when connecting two pipes of different types.

What is ASME code for piping?
The ASME-ANSI B 31 Codes. ASME B31 was earlier known as ANSI B31. The B31 Code for Pressure Piping, covers Power Piping, Fuel Gas Piping, Process Piping, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids, Refrigeration Piping and Heat Transfer Components and Building Services Piping.
What do the markings on PVC pipe mean?
If you purchased your PVC pipe from a hardware store, you can use the markings on the side of the pipe to tell you what size you have. It will normally indicate the size in decimal or fraction, close to where the manufacturer’s name is, such as ‘1.25’ (for 1-1/4″) or “3/4” (for 3/4″… obviously).
What are the different types of pipe fitting?
How many types of pipe fitting are there?
Generally there are two types of couplings are available. Compression coupling and slip coupling. Compression coupling is regular coupling which is connected between two pipes and it prevents leakage by the arrangement of gaskets or rubber seals on both sides, otherwise glue is provided.
