Threaded Flanges

Threaded Flanges

The most noteworthy feature of these changes is that they can be joined to a pipe without welding. The bore of Nickel Threaded / Screwed Flanges have threads and can be fitted to pipes that have external threads. Stainless Steel Threaded / Screwed Flanges are low priced, t best for small pipes and can be used in low-pressure applications. They are very beneficial in highly combustible industries where welding is dangerous. We are certified to cater to the challenging requisites of a number of industries through our outstanding products and extraordinary services.

Manufacturing Process

How Our Stainless Steel Flanges Are Manufactured

01

Raw Material Selection

Certified stainless steel billets are selected according to ASTM, ASME, and EN standards.

02

Hot Forging

Billets are heated and forged into the required flange shape for maximum strength.

03

CNC Machining

Precision machining creates the bore, facing, bolt holes, and required dimensions.

04

Heat Treatment

Stress relieving and solution annealing are performed whenever required.

05

Inspection & Testing

PMI, dimensional inspection, hydrostatic testing, and NDT ensure product quality.

06

Surface Finishing

Flanges are cleaned, pickled, passivated, and finished as per customer requirements.

07

Marking

Each flange receives grade, size, heat number, and standard identification markings.

08

Packaging & Dispatch

Products are packed securely with flange protectors, wooden pallets, and export-ready crates.

Frequently Asked Questions About Threaded Forged Fittings

What pressure classes do your Threaded Forged Fittings cover?

Our Threaded Forged Fittings are manufactured in Class 2000, 3000, and 6000 pressure ratings in accordance with ASME B16.11 specifications. They feature NPT (National Pipe Thread) taper threads that provide high-integrity mechanical sealing without the need for welding.
