Lap Joint Flange
Lap Joint Flanges Manufacturer
JK ENGINEERING WORKS is reckoned amongst the prominent in Industrial Carbon Steel Lap Joint Flanges Exporter in India. A lap joint flanges is one that slides directly over the pipe. These types of flanges are used in applications that call for regular dismantling. Lap joint flanges are basically two-piece devices that are very akin to loose slip-on flanges and weld-neck flanges. Lap joint flanges are used a lot with stub end fittings. The stub end will have a pipe welded to it and the lap end type of flange can thus freely rotate around the end of the stub.
With this kind of an arrangement, there is no issue experienced with bolt hole alignment. There are various advantages to using Stainless Steel Lap Joint Flanges. One of these is that as a result of using such types of flanges, there is no contact with the fluid in the pipe. And this allows for the usage of inexpensive carbon steel flanges when corrosion resistant pipes are used.
What is Lap Joint Flanges
The Lap joint flanges use a stub end that is welded to the pipe. permitting easy flange alignment of the bolt holes. A lap joint flange is also called Van Stone or Stub Flange. A stub ends are available in three styles (Types A, B, and C) and two lengths (Short and Long).
