LAP JOINT STUB END HASTELLOY B3 NICKEL ALLOY BUTT WELD FITTINGS
Overview:
Hastelloy B3 is a nickel-molybdenum alloy that is highly resistant to a wide range of corrosive environments， including both oxidizing and reducing acids. Hastelloy B3 lap joint stub end is a type of piping component used in industries where highly corrosive materials are handled， such as chemical processing， petrochemical， and oil and gas industries.
A lap joint stub end is a fitting used in combination with a lap joint flange， and together they form a leak-proof connection between two pipes. The Hastelloy B3 lap joint stub end is made of the same alloy as the pipes it is connected with， so it provides excellent corrosion resistance and durability.

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. | ||||||||
