Threaded Flange

We are a professional threaded flange factory and thread flange supplier. It is connecting with pipe without welding. It is similar to slip on flange or a socket weld flange, fitted with a tapered thread (screw) inside the flange bore that is mounted on the pipe with corresponding external threads. In some cases a seal weld also applied in conjunction with threaded pipe flange.

Our Supply Range as thread flange supplier

Standard: ASTM A105, ASTM A182
Material: Carbon Steel, Stainless Steel, Alloy Steel
Size Range: 1/2'', 1'', 2'', 3'', 4'' to 24''
Pressure Class: Class 150 to 2500
Face: Raised face (RF), Ring type joint (RTJ)

Though threaded pipe flange is available in different dimensions, threaded fittings mostly is used in small diameters pipeline. (Below 4 inch) 

On the other hand, it is not compatible with a pipe system in thin wall thickness, since there is no space for doing the threading. 

Threaded Flange as threaded flange factory

Threaded Flange is widely demanded as pipe flanges used in different industrial applications as threaded flange manufacturer. They are the special type of pipe flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which match an external thread on the pipe.
These threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter. Sometimes a seal weld is also used together with the threaded connection. They are available in various sizes and materials.

 As a professional thread flange supplier, we can supply good quantity and good service.

 flange Materials used as threaded flange manufacturer:

  • Stainless Steel
  • Alloy Steel
  • Carbon Steel
  • Cast Iron
  • Steel

How to measure threaded flange?
Take the measurements of the following:

  • O: Flange Diameter
  • Q: Flange Thickness
  • X: Hub Diameter at Base
  • RF: Raised Face Diameter
  • BC: Diameter of bolt circle
  • L: Length through hub
  • T: Thread Length

Key Features:

  • No welding is required.
  • Good for small pipe sizes.
  • Should be avoided for larger loads, especially when subjected to higher torque.

Uses of threaded flanges:

  • 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.
