Product Description

Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.

This type of joint connection is Speedy and simple but not suitable for high presser and temperature applications. Threaded Flanges are mostly used in utility services such as air and water.

Threaded (Screwed) flange is similar to the Slip-On flange, but the bore is threaded. Its chief merit is that it can be assembled withour welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.


Uses of threaded flanges

Threaded flanges are threaded in the bore which match an external thread on the pipe. Threaded flanges are used with pipes that have external threads. The benefit of these flanges is that it can be attached without welding.

Threaded flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these flanges are highly demanded.

They can be used in extremely high pressure applications, particularly at or near atmospheric temperature, where the necessary post weld heat treatment is not possible.

They are ideal for small diameter piping applications.

They are economical and time saving devices.

These threaded flanges are normally designed for non-cyclic applications.

The flanges are suitable to be used in applications where welding is hazardous.

They can be used in highly explosive areas.


They are the special type of pipe flanges which can be attached to the pipe without welding.

Threaded flanges are often used for small diameter, high pressure requirements. thread flanges with a hub have published specifications that range from 1/2″ thru 24″.

Threaded Flange Types

There are two types of threaded flanges. One is to seal the two pipe ends with a certain sealing surface and a lens pad. This type of flange is mostly used for ammonia production. But it has been used less recently, and the lens pad has been replaced by a metal ring.

The other type is the same as a normal flange, sealed with two flange sealing faces.
