What is a welded branch connections?
Branch Connection fittings (also known as O’lets) are fittings which provide an outlet from a larger pipe to a smaller one (or one of the same size). The main pipe onto which the branch connection is welded is usually called the Run or Header size.

What is branch fitting?
Branch fittings are piping elements installed to allow a fluid flow to join or leave the flow in a main pipe. The magnitude of pressure losses or gains caused by a branch fitting is determined by the angle at which it connects different pipes, and the relationship between the volume flow rates in these pipes.
Which fitting is used for branch connection in piping?
The weldolet or welding outlet is the most popularly used branch connection fitting. The architecture of the weldolet minimizes the concentration of tension and provides overall strengthening. It has a beveled end and is attached by butt welding to the branch shaft, so it is part of butt weld fittings.
What are welded pipe fittings?
Welded pipe fittings are made of ERW welded carbon steel or stainless steel pipe. They are available in sizes ½” to 72” and are more affordable than seamless fittings.
What is difference between weldolet and Sockolet?
What is the difference between a Sockolet and a Weldolet? Sockolets belong to the “socket fittings” family and are available in classes 3000#, 6000# and 9000#, whereas Weldolets are buttweld fittings. Sockolets are used for lower pressure applications, and smaller pipe diameters, than Weldolets.
What does Branch mean in plumbing?
A branch is any secondary part of the drain system; also, referred to as the lateral line.
What is a branch pipe?
branch pipe means any pipe conveying soil-water or waste-water either separately or together to a stack or other vertical pipe; Sample 1Sample 2Sample 3.
What are the 4 types of fittings?
Types of Pipes and Fittings
- Elbows: Used to change the angle or direction of the pipe run.
- Street Elbows: One end of the pipe fitting has male threads and the other end has female threads.
- Tee Fittings: Shaped like the letter T.
- Couplings: Used to join two straight pieces of pipe of the same diameter.
What are the types of fitting?
Fittings are generally used in mechanical and plumbing operations for a number of different purposes. There are many different kinds of fittings, made from a variety of materials: some of the most common types are elbows, tees, wyes, crosses, couplings, unions, compression fittings, caps, plugs and valves.
What is fitting in welding?
A fitting is a piece used to fuse two tubes together, allowing for liquids to pass through inside. The welding quality of standardized microfit fittings must be impeccable in order to ensure the tubes are leak proof, so that no gas or liquid is released.
How are weld fittings made?
BW fitting’s dimensions and tolerances are defined as per ASME standard B16. 9. A butt weld pipe fitting is made by the process of hot forming that includes bending and forming to shape. The starting material of butt weld fitting is a pipe that is cut to length, heated and molded into specific shapes by means of dies.
Where is weldolet used?
A weldolet is a branch butt-weld connection fitting that is adhered to an outlet pipe to minimize stress concentrations in the piping area.
What is a Sockolet used for?
What is Sockolet. Sockolet is used for 90 degree self-reinforcing branch accessory, and is suitable for small instrument connection or small branch pipe. It has the same basic design as “weldolet” or “threadolet”, but its branch connection is socket weld type. The sockolet has full size or reduced size.
Is PEX A or B better?
Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest. You should never install kinked pipe. Bursting Pressure – Always check the tubing for maximum temperature and pressure ratings. Remember, the pressure ratings decrease as the temperature of the water increases.
What is the pipe next to the toilet called?
Cold Water Supply Pipe – In every bathroom there should be a small valve sticking out of the wall right next to the toilet. This valve is called the cold water supply pipe. It supplies the entire toilet with water.
What is a fire branch pipe?
A branch pipe is used to direct the flow of water at the end of a fire hose into a nozzle, also sometimes known as a fire hose water director.
What is stub on branch connection?
Stub-on is generally used when the branch is equal to or one size smaller than the main pipe. For “stub on,” the stub extends only to the outside of the main pipe.
What are the three types of fittings?
Tees, Wyes and Crosses
All three designs come in standard designs (in which all outlets/inlets are the same diameter) and reducing designs (in which one or more is a different size).
What are the 5 different pipe fittings?
Types of pipe fittings and their purposes:
- Elbows: Used to change the angle or direction of the pipe run.
- Street Elbows: One end of the pipe fitting has male threads and the other end has female threads.
- Tee Fittings: Shaped like the letter T.
- Couplings: Used to join two straight pieces of pipe of the same diameter.
What is the name of pipe fittings?
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.
What is the difference between welding and fitting?
Pipefitters are often required to work in confined and hot spaces for lengthy periods of time. A welder fabricates and puts together metal parts. It is done through the use of various machines that create intense heat to fuse the metals.
How many types of pipe fittings are there?
The main and most commonly sought are: elbows, tees, reducers, unions, couplings, crosses, caps, swage nipples, plugs, bushings, adapters, outlets, valves & flanges. These pipe fittings can be found in various pressure classes ranging from 150 PSI to 3000 LB.
What is the difference between forged and wrought fittings?
The main difference between wrought and forged steel is strength. Forged steels are tougher than wrought steels as they begin as a casting which is then forged which adds to its durability. Wrought steel is less likely to be used in high-tension applications and it may be harder and more brittle than forged steel.
What is a 3R fitting?
3R means 3 times the radius as the nominal pipe size. Items are available in Carbon Steel, 304/304L, & 316/316L Stainless Steel.
How many types of OLET are there?
There are 13 types of Branch Connections including: Weldolet (WEL) Threadolet (TOL) Sockolet (SOC)
