High Light Lap Joint Stub End ，316L ASME B16.9 Fittings ，Type A Butt Weld Stub End
Lap Joint Stub End Butt Weld Fittings 316L ASME B16.9 DN80 SCH10S Type A
A lap joint stub end butt weld fittings element lets you build a flanged connection that can be rotated and re-aligned before the bolts are tightened. This makes assembly faster and reduces the risk of mismatched bolt holes, especially in cramped or hard-to-reach piping.
The stub end is welded to the pipe, while a separate backing flange slides over the stub. Because the flange is not welded to the pipe, the joint can be opened and the flange reused again and again. This design is widely chosen for lines that need frequent inspection or maintenance.
We manufacture lap joint stub end butt weld fittings to ASME B16.9 in both Type A and Type B, in 316L, 304L, carbon steel, duplex and nickel alloys. The face is machined flat or raised as required, and the bore is pickled and passivated for corrosion resistance.
Each lap joint stub end butt weld fittings element is dimensionally inspected and hydrostatically tested, and is supplied with a material test certificate for full traceability. Whether you need a single DN80 Type A stub end or a complete flanged spool set, we can deliver.

Frequently Asked Questions
What is the advantage of a lap joint stub end?
The backing flange can rotate, so bolt holes line up easily, and the flange can be removed and reused when the joint is opened for maintenance.
What is the difference between Type A and Type B stub ends?
Type A has a straight barrel and Type B a shorter barrel for a closer flange fit. We supply both in lap joint stub end butt weld fittings.
Are these stub ends supplied with certificates?
Yes. Each 316L stub end comes with an EN 10204 3.1 material test certificate.
Can you supply the matching backing flanges?
Yes. We can supply matching lap joint flanges so the complete joint uses one compatible material system.
