What is Carbon Steel Lap Joint Flange

lap-joint-flange

Carbon steel lap joint flange is a kind of two-piece pipe flange connection which is easy to install. Lap joint flanges are cost-effective and well-suited for corrosive applications.

The term “Lap Joint”was likely derived from the Old French “lappe” which means “overlap”. The lap joint is still widely used today. The lap joint is a versatile and reliable method for joining two pieces of wood together.

Carbon steel lap joint flange and stub-end assembly are used mainly in pipe systems that demand dismantling for inspection or daily maintenance. It is also used in the erection of large diameter or hard-to-adjust piping configurations because of its quick bolt hole alignment.     

Materials for Lap Joint Flange

Lap Joint flanges are manufactured in various materials include a range of carbon steel, alloy steel, stainless steel and so on. These flanges are available in common dimensions like other flange types which makes it easy to integrate them into existing piping systems or use alongside other piping components.

Purpose of Carbon Steel Lap Joint Flange

Carbon Steel Flanges including carbon steel lap joint flanges are an integral part of many piping systems. They're attached to pipes, pumps, valves etc. There are several different types of flanges, including lap joint flange, weld neck flange, blind flange, and many others.

Application

Oil and gas Industry

Chemical industry

Power industry

Shipbuilding industry

Construction industry

Way to Install Lap Joint Flange

To assemble a lap joint flange and stub end, the stub end must slide into the bore of the flange ring and then be welded to the pipe. One side of the stub end forms the sealing face, while the opposite side presses against the lap joint flange ring (when the flange is assembled).
