What is a BW fitting?

Butt weld (BW) fittings are defined in the ASME B16. 9. They are welded at their ends to pipe end, with the same thickness as pipes. The end of butt weld fittings shall be beveled.

What is BW in piping?

BW. BW is an abbreviation of Butt Weld(ing). A Butt Weld is a circumferential butt welded joint, and the most common type of joint employed in the fabrication of welded pipe systems. A butt joint is the most universally used method of joining pipe to itself, fittings, flanges, valves, and other equipment.

What is a BW flange?

Butt welding(BW) is the welding of pipe fittings,pipe fittings,flanges or pipes.

Are butt weld fittings seamless?

They forget to mention welded or seamless butt weld fitting: Butt weld fittings are available in both welded and seamless configuration. A seamless butt weld carbon steel or stainless steel fitting is made of seamless pipe and is generally more expenses. Seamless pipe fitting is NOT common in sizes bigger than 12”.

What are the kinds of fitting in piping?

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 a WPB fitting?

ASTM A234 WPB Pipe Fittings means that the pipe fitting with ASTM A234 WPB material and is used for the system of pressure piping of high or moderate temperature services. WPB is a steel grade in which W stands for weldable, B is grading B and P stands for pressure. Thus it is referring minimum yield strength.

What is FW in piping?

FW = field weld. FFW = field-fit weld. A field-fit weld indicates that the designer has foreseen that the piping may need adjustment in the field so has added an extra length of pipe at a buttweld fitting or flange.

What is difference between socket weld and butt weld?

Socket welding can be used for pipes with small diameters, and it is generally applied to pipes or pipe fittings whose diameters are less than DN50. Butt welding is widely used for pipes with big and small diameters, and threaded welding or socket welding is used for pipes with small diameters.

What is welded tee?

Welding tees are used to create derivations on the main pipe. They are made from electrically welded pipes for diameters below DN 300 and from plates for larger diameters. Fitting Service offers standard tees, creating a side deviation from the pipe, while keeping the whole section unchanged.

What is Buttweld carbon steel pipe fittings?

Buttweld Carbon Steel and Stainless Steel Pipe Fittings. Buttweld pipe fittings comprises of long radius elbow, concentric reducer, eccentric reducers and Tees etc. Butt weld stainless steel and carbon steel fittings are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system.
