Product Description

ASME B16.5 A105 DN80 Class 150 LJF FF Lap Joint Flange

Product introduction
Lap Joint flanges go by a range of names, including:
Back Up flanges
Loose Ring flanges
Loose Hubbed flanges
Van Stone flanges
They're a two-part flange consisting of a Lap Joint Stub End which is butt welded to the pipe and a backing lap joint flange which is slid onto the pipe before welding the Stub End.
Lap Joint Flanges slide directly over a pipe and are used with Stub Ends. Typically, a pipe is welded to the Stub End leaving the Lap Joint Flange to rotate freely around the stub end, simplifying bolt hole alignment.
