LAP JOINT STUB END WP904L STAINLESS STEEL BUTT WELD FITTINGS

Overview:

WP904L is a high-alloy austenitic stainless steel that offers excellent corrosion resistance in various environments. A lap joint stub end, also known as a lap joint flange, is a type of piping component used to connect pipes of different materials or sizes. It consists of two parts: the stub end, which has a large outer diameter and a small inner diameter, and the backing flange, which is used to bolt the stub end to another flange or fitting.

The WP904L lap joint stub end is made of this high-grade austenitic stainless steel material and is designed specifically for use in corrosive environments. Its special properties make it an ideal choice for demanding applications in industries such as chemical processing, food and beverage, and pharmaceuticals. The main advantage of a lap joint stub end is its ability to rotate freely, which allows for easy alignment and adjustment during installation.

Notes:


1) When the short type is used on the larger flanges with PN 50 and PN 110(300 and 600 LB) and on flanges with PN 150(900 LB) and above, or the long type is used on the larger flange with PN 260 and PN 420(1500 and 2500LB), the length of the cylinder may be added to be feasible the welding, the adding length shall be negotiated by manufacturer and purchaser.


2) The thickness of joint shall be added if the TG and MFM contact surface of flange are used, and the adding thickness shall increase (not be included in) the base length F.


3) The radius of fillet R(type A) shall conform to the ones of loose flanges according to GB/T 9118.1 9118.2 or ASME B16.5. The radius of fillet R (type B) is only applied for the standards of MSS SP-43 with short length F.


4) The lap joint diameter G shall conform to the standard machined face indicated in ASME B16.5 , and the back of joint shall be machined to conform to the surface of installation.When RJ used, the size K specified in ASME B 16.5 Shall apply.


5) The minimum lap joint thickness t shall not be less than the nominal pipe wall thickness.
