Lap joint flange RTJ (Ring Type Joint) has a raised face with the groove machined to the face of flange in order to accept metal ring gaskets.

Lap joint flange and lap joint stub end are used together as a assemble system. The stub end will connect with the pipe and lap joint flange slide over the pipe. The flange itself is not fixed to pipes in any way, so that it is free to spin for proper alignment. This flange pairs usually used in low pressure applications without high loads on them.

Zizi offers forged flanges and pipe fittings in various materials such as stainless steel, super duplex stainless steel, carbon steel, alloy steel, copper alloy and nickel alloy.

Copper Nickel Flange

Copper Nickel Lap Joint Flange RTJ C71500 has advantages of great corrosion resistance, outstanding mechanical and physical properties as well as easy to shape, fabricate and weld. They are widely used in ship building, chemical and petroleum industry.

Copper Nickel Alloy Flange

Advantages of Lap Joint Flange and Stub End

1. Saving cost when the pipe is made of exotic materials.
2. Facilitate the lining up of opposing flange bolt holes.
3. More durable due to the flange is not direct contact with the fluid inside.
4. May be salvaged for re-use.

We are manufacturer of lap joint flange in kinds of materials such as carbon steel, stainless steel, alloy
Lap joint flanges fit over the pipe and are most commonly used with Stub End Fittings. A pipe is typically welded to the Stub End and the Lap Joint is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. These are often used for applications that require frequent dismantling.

Feature

Pressure: 150# – 2500#
Size: from ½” (15 NB) to 48″ (1200NB)
Material: ASTM A105 F1/ F5/F9/F11/F22/F91.304/310/316/321/347 Nickel, Monel , Inconel, Hastelloy C 276
Surface treatment: Transparent oil, rust-proof black oil or hot galvanized
