If you are looking for the best quality flange that is suitable for your industrial requirement and are customized as according to your demand. If yes, then this article will help to find the good quality flanges that offer various features and are cheap to buy. The lap-joint-flange is made with the superior quality material, comes in standard size such as stainless steel and carbon steel lap joint flanges. These joint flanges are similar to any other industrial flanges and it does not have raised face but offer some unique feature. The initial manufacturing cost of lap joint flanges is higher one-third times as compared to other welding neck flanges.

Specifications- This lap joint flange is mainly used in the piping system which requires regular cleaning and inspection. The Pressure ratings of this flanges range from class 150 to 2500 and have international standards such as ANSI series and custom drawings and size varies from 15 NB to 1200 NB.

Benefits of using lap-joint-flange

  • 1. These flanges can be easily reused and this protects the system to corrode quickly.
  • 2. This lap joint flange often allows using of inexpensive carbon steel flanges with other anti-resistant pipe and lack of contact with the fluid inside the pipe.
  • 3. These flanges facilitate to swivel around the pipe and provide lining up to the opposite of the flange.
These lap joint flanges are exported in many countries and regions and are used in various applications such as shipbuilding, paper mills, pharmaceutical, oil refinery, power generation plants, petrochemical plants and many other industries.

Lap Joint Flanges


The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.The lap joint flange with the stub end assembly is normally used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).

Benefits of using lap joint flanges:

» Freedom to swivel around the pipe facilitates the lining up of opposing flange bolt holes.
» Lack of contact with the fluid in the pipe often permits the use of inexpensive carbon steel flanges with corrosion resistant pipe.
» In systems which erode or corrode quickly, the flanges may be salvaged for re-use.
