Free flange

Loose sleeve flange is a kind of steel parts, commonly used as the connection is the change of materials, the product standard is GB/T 9120-2010.

use

Commonly used as a connection is a change in material.

The flanges of loose sleeve are used to cover the flanges on the pipe end with flanges such as flanges and steel rings. The flanges can move on the pipe end.A steel ring or flanging is a sealing surface, and a flange is used to compress them.Thus it can be seen that the loose flange does not contact with the medium because it is blocked by steel ring or flanging.

Loose sleeve flange is suitable for connecting and corrosion-resistant pipeline of stainless steel, aluminum and other non-ferrous metal and stainless acid-proof steel container.

Slip-on flange, flange can be activity is usually necessary in water supply and drainage (most common) on the slip joint fittings, factory factory will each have a piece of flange on both ends of the expansion joints, directly with the engineering of piping, equipment, bolting.

It's the flange with the sleeve.Usually used in pipes, in which case loose bolts can be used to rotate both sides of the pipes and tighten them.It is convenient to disassemble and install pipelines.Loose flange is also called loose flange.
