Precision Forging SS Lap Joint Flange With Stub Ends

Precision Forging SS Lap Joint Flange With Stub Ends

Lap Joint Flange does not have a raised face, it is used in conjunction with a “Lap Joint Stub End”- a lap joint stub end and a lap joint flange. The use of it at points where severe bending stress occurs should be avoided.

Since the lap joint flange itself is not welded to the pipe, it may rotate to align bolt holes readily and the assembly and disassembly are much easier. This feature simplifies installation, maintenance, and repair tasks, reducing downtime and overall costs. The design of the flange allows for angular misalignment of pipes, ensuring a tight and leak-proof joint even when pipes are not perfectly aligned.

The crevices formed between the internal surface of the flange bore and the external surface of the stub ends may collect contaminates readily. The collected contaminates could present a problem and result in crevice corrosion.

They are usually used in low-pressure applications, such as petrochemicals, oil and gas, water treatment, food and beverage, and chemical processing industries.
