What is Stainless Steel Lap Joint Flange

Lap wjoints are essentially a modified version of the butt joint. They are formed when two pieces of metal are placed in an overlapping pattern on top of each other. They are most commonly used to joint two pieces with differing thicknesses together. Welds can be made on one or both sides.

Stainless steel lap joint flanges are fillet welded to a position and are ideal for low-pressure applications. Blind flanges are designed without a bore and are used to seal vessel openings or piping systems. These flanges are ideal for piping systems or vessels that require regular inspection.

When bolted up the stainless steel lap joint flange, we compress the stub end to the gasket and the other mating surface and make the seal. Stub ends and lap joints are normally used in piping systems.

Stainless steel lap joint flanges include ASTM A182 F304/304L/304H-F316/316L-F317- F310S-F321-F347-F904L.

Benefit of Stainless Steel

As a kind of material, stainless steel is known for its high strength and resistance to corrosion, heat and chemical damage. These properties mean stainless steel fittings can be used in virtually any application in various condition and environments.

What is the Difference Between Lap Joint Flange and Weld Neck Flange

lap-joint-flange

Lap Joint Flange

weld-neck-flange_副本

Weld Neck Flange

Lap joint flanges are the ones called for by the line class then you may only use lap joint flanges. For other line classes you would normally use weld neck flanges for all flange situations for 3” (NPS) and larger. The use of a slip-on flange could be an exception only when there is a space limitation problem.

Advantages of Lap Joints

It is a relatively easy joint to cut and a great learning joint if you are just getting going in woodwork. While not particularly strong, lap joints are simple joints you can use to make picture frames and mirrors. A lap joint falls into the category of halving joints – where two halves make a whole.

High strength and durability

Good plasticity and weldability

Wide application range

Standardization and Interchangeability

Excellent cost-effectiveness
