Threaded flanges are widely demanded as pipe flanges used in different industrial applications. 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 matches an external thread on the pipe. We can offer a comprehensive range of Threaded Flange for the right technical solution. Piyush Steel manufacture & export wide selections of ANSI B16.5 Threaded Flange & ASME B16.47 Threaded Flange at most attractive price as per customer requirements, we can also manufacture Threaded Flange in ASTM/ASME/ANSI grades as per our customer budget, we enjoy the reputation supplying Threaded Flange at cheapest in steel industries around the globe.

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 of Threaded Flanges:

  • 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.

Threaded Flange Description

Other Name: Threaded Flange, Screwed Flange, NPT Flange, B16.5, ASTM A105, CNC Screwed, 1/2-24, 150, 300

Threaded pipe flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. Threaded pipe flanges are used with pipes that have external threads.
