Flanges, Slip-On

Haji Iron and Steel Works offers Slip-On Flanges. This slip-on flange has a low hub because the pipe slips into the flange prior to welding. It is welded both inside and out to provide sufficient strength and prevent leakage. They are ideal for low pressure applications.

A Flange allows two pipes to be mechanically connected together, or a pipe to be mechanically connected to a valve, tee, choke or other piece of equipment. The principle of a flange is to use a mechanical force (exerted by the bolts) to pre - load the gasket sufficiently so that when internal pressure (end cap force) is applied, there is enough contact stress between the flanges and gasket to maintain a seal. The Flange it self needs to be connected to the pipe. This is usually achieved by welding though threaded and other weldless connections also exist.
