Short Description:

A pipe flange is a device that connects pipes. It usually consists of two ring flanges that fit together, bolts and gaskets used to connect the flanges. Flanges are widely used in piping systems in various fields, such as chemical, petrochemical, water treatment and other industries. Different types of flanges are suitable for different pressure levels and temperature ranges, and can be matched with various pipe connection methods, such as butt welding, threading, flanging, etc.

Lap joint /loose flange

These flnages are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. The lap joint is favoured in low pressure application because it is easily assembled and aligned. To reduce cost these flanges can be supplied without a hub and /or in treated, coated carbon steel.
