What is a takeoff in pipefitting?

What are the 5 different pipe fittings?

There are different kinds of pipe fittings used in piping systems. The main and most commonly sought are: elbows, tees, reducers, unions, couplings, crosses, caps, swage nipples, plugs, bushings, adapters, outlets, valves & flanges.

How many types of pipe fitting are there?

Coupling, Adapter, Bushing and Union Fittings



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 are the 4 types of fittings?

Types of Pipe Fittings in Plumbing System

• Elbow.
• Reducer.
• Tee type.
• Cross type.
• Coupling.
• Unions.
• Adaptors.
• Olet.

What are pipeline fittings?

Pipe fittings are components used to join pipe sections together with other fluid control products like valves and pumps to create pipelines. The common connotation for the term fittings is associated with the ones used for metal and plastic pipes which carry fluids.

What color pipe is used for water?

COLOR OF PIPE

Why are pipes called nipples?

Video quote: Section so that a wrench or a plier can grip onto. It. Or barrel nipples which lack this feature some pipe nipples lack any unthreaded area connecting male thread right to male thread.

What is socket pipe?

A socket is a fitting that simply goes over the end of a pipe. A 1″ socket end will fit on a 1″ pipe. These are extremely common. Many PVC couplings have socketed ends. A commonly used abbreviation for “socket” is “soc.”

What is swage in piping?

Swage nipple is also called reducing nipple,is a kind of forged pipe fitting.It is usually used MSS SP-95 standard,common materials are carbon steel,stainless steel and alloy steel.

How are pipe nipples made?

Pipe nipples are manufactured by cutting a specified length of pipe and applying the desired end connections. The pipe nipple dimensions and material follow from pipe specifications. Similar to pipe, pipe nipples also come in either a seamless or welded construction.

How do you measure pipe nipples?

To calculate the portion of pipe left from end of fitting to end of fitting when it is installed you have to subtract the engagement length of both ends. The “close” length is the shortest nipple length that can be created, when its installed the fittings are right up against each other with no pipe showing.

How do I calculate pipe size?

The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.

How do you size an fitting?

AN sizes range from -2 (dash two) to -32 in irregular steps, with each step equating to the OD (outside diameter) of the tubing in 1/16″ increments. Therefore, a -8 AN size would be equal to 1/2″ OD tube (8 × 1/16 = 1/2).

What are standard pipe sizes?

Steel Pipe Sizes – Schedule 40

What is OD and ID of pipe?

The outside of the pipe is always larger than the inside. The difference between the inside diameter (ID) and the outside diameter (OD) is due to the thickness of the wall. Wall thickness also determines the strength of the pipe.

What is nominal thickness of pipe?

Nominal Pipe Size (NPS) is a North American set of standards used to designate pipe diameter and thickness. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) for inside diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness.
