Lap Joint Flange

A lap joint flange is a high-performance,two-component piping connection solution.It is uniquely designed with a separable structure,consisting of a precision-machined stub end and a loose backing flange.

The stub end,which is directly welded to the pipeline,forms the primary pressure boundary and corrosion-resistant barrier.The backing flange,a non-welded ring,is slipped over the stub end and serves solely to compress the joint via bolting.This design offers unparalleled advantages:

Superior Alignment Flexibility:The free-spinning backing flange eliminates bolt-hole misalignment,drastically reducing installation time and labor.

Economic Material Optimization:For systems using high-grade alloys(stainless steel,duplex),the backing flange can be made from lower-cost carbon steel,significantly reducing material costs by 30–50%.

Hygienic&Cleanable Design:The smooth,crevice-free internal weld is perfect for high-purity applications in food,beverage,and pharmaceutical industries requiring CIP(Clean-In-Place)procedures.

Versatile Application:Ideal for systems requiring frequent dismantling,maintenance,or where piping alignment is challenging.
