WP310S WP321 Stainless Steel Butt Weld Fittings Equal Tee ASTM A403

ASTM A403 WP304/L WP316/L WP310S WP321 Stainless Steel Butt Welding Equal Tee

Steel pipe tee has three branches that can change fluid direction. It has T-shaped or Y-shaped, and include Equal Tee and Reducing Tee (Reducer Tee). Steel tee is widely used in pipe networks for convey liquids and gases.

Butt weld tee is widely used in petroleum, aerospace pharmacy, chemical industry, metallurgy, electric power, military industry, engineering support and other industrial pipelines.

Ends in plain or beveled, connected by butt welding process. It can withstand higher pressure than other types. The size of butt weld tee should be specified in pipe NPS (DN) and thickness in schedule, where the socket weld tee or thread tee thickness should be specified in the pressure level.

Butt Welding (BW) Tee Types

BW Tee is categorized into two types according to branch diameters and functions there are:

Equal Tee: Three branches of tee have same diameters. Also named as Straight Tee.

Reducing Tee (Reducer Tee). : The branch diameter is smaller than main diameter. The reducing tee is usually described as NPS diameters in 4” x 4” x 3”, where 4” is the main line pipe diameter, and 3” is the reducing branch.

Product Information

ASME B16.9 Equal Tee Dimensions (mm)

The ASME B16.9 equal tee is a three-way fitting used to make perpendicular connections to a pipe.

*NPS: Nominal Pipe Size; O.D: Outside Diameter at Bevel; C: Center-to-End, Run; M: Center-to-End, Outlet.

Materials Chemical Compositions

ASTM A403 Stainless Steel Pipe Fittings refers to the material of forged and rolled austenitic stainless fittings for pressure pipes. Common grades are WP304/L, WP316/L. They can be used into many fields as engineering industry, energy conversion plants etc

Note:

• Where a ellipsis(﹍)appears in the table, there is no requirement and the element need to be analyzed for or reported
• The method of analysis for nitrogen shall be a matter of agreement between the purchaser and manufacturer
• Columbium 0.10-0.30%; Vanadium 0.10-0.30%.
• For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.04% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500in.(23.7mm) in outside diameter and light wall tubes as those less than 0.049in.(1.24mm) in average wall thickness
