Forging High Quality Alloy Steel Tee

Forging High Quality Alloy Steel Tee

Bangdong Supply Alloy Steel Tee,Forging Steel Tee,Seamless Steel Tee.Buttweld pipe fittings comprises of long radius elbow, Concentric Reducer, eccentric reducers and Tees.They are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. BW fitting`s dimensions and tolerances are defined as per ASME standard B16.9.

Butt Weld fittings are also called Welded Pipe fittings. These welded fittings in carbon steel and stainless steel offer many advantages compared to threaded and socketweld fittings. The later are only available up to 4-inch nominal size whereas butt weld fittings are available in sizes from ½" to 72".

Butt Weld Pipe Fitting Bevel

All welded pipe fittings have bevelled end to allow for ease of welding. This bevel allows for full penetration weld in most cases. There are two types of bevels;

Plain Bevel and Compound Bevel

Buttweld Pipe Fitting Specification & Standards

Welded pipe fittings are made as per ASME spec B16.9. Asme B16.9 covers factory made wrought steel butwelding fittings in sizes 1/2" to 48". This standard however does not cover low pressure corrosion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-Welding Fittings.

Common Materials for Welded Pipe Fittings

Carbon Steel Welded Fitting:

A234 WPB is the most common material used for carbon steel butt welded fittings.

Astm A234 WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service.
