Product Description


Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with Lap Joint Flange stub end the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges.
Lap joint flange is having two components, a stub end, and a loose backing flange. Stub end is butt welded to the pipe and Backing flange freely move over the pipe. The backing flange can be of different material than stub material and normally of the carbon steel to save the cost. Lap flange is used where frequent dismantling is required, and space is constrained.

The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face.

LPJ flange 5

The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end. Normally, a lap joint flange and a lap joint stub end are mated together is an assembly system.

These flanges are nearly identical to a Slip On Flange with the exception of a radius at the intersection of the flange face and the bore to accommodate the flanged portion of the Stub End.

Flange Material:


Forged Steel Flange are perfectly finished with precision using the latest machinery.

Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.
Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

Forged Stainless Steel Flange

Forged Steel Flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard. Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.

Forged Pipe Fittings are suitable for connection of steel pipes conveying mediums such as steam, oil, air and water. They are widely used in Chemical industry and Shipbuilding . And the flanges are suitable for welding.The flanges mainly include Welding Neck, Blind, Slip-on, Lap-Joint, Socket,Reducing and Plate type.

Size available: 1/2"--72"(DN15-DN1800).

Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard.

In the production, press the mass of the forging parts, the quantity of the batch of different forging methods. Free forging productivity is low, processing surplus is large, but the tool is simple, universality is large, so it is widely-

Forged steel flanges are made in seven primary ratings:
Asme B 16.5 Class 150 lb 400 lb 900lb 2500lb 300lb 600lb 1500lbcutting and then continue to beat, to eliminate the ingot in the segregation, loose and other defects. Price and mechanical properties are higher than ordinary casting flange a grade. The flange is a part that connects the pipe with the pipe and the valve, is connected to the pipe end. It is also used for the flange on the equipment inlet and outlet.
