What is Alloy Steel Lap Joint Flange

Alloy steel lap joint flange is a two-piece pipe flange connection. Lap joint flanges are cost-effective and can accommodate minor misalignments, and are well-suited for corrosive applications.

Alloy steel is a type of steel with alloying elements. Some of the common additions to alloy steel include: chromium, cobalt, columbium, molybdenum, manganese, nickel, titanium, tungsten, silicon, and vanadium.

The alloy lap joint flange and stub end assembly are mainly used in pipe systems and is used in the erection of large diameter or hard-to-adjust piping configurations as well.

Notes:

1) Weights are based on manufacturer's data and are approximate.

2) Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is nonstandard).

3) If you need class 300 ,600 ,900 ,1500 ,2500 flange dimensions & weight,please contact us.

Advantage of Lap Joint Flange

Flange fitting connections can be easily assembled and provide the best option in larger diameter applications under high pressure. They provide significant advantages versus threaded fittings in these larger, more severe applications, such as easier to assemble in tight spaces.

High strength and durability

Good plasticity and weldability

Wide application range

Standardization and Interchangeability

Excellent cost-effectiveness
