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 Plate Flanges

When should I choose a Plate Flange instead of a Forged Flange?

Plate Flanges, typically cut from flat steel plates such as ASTM A240 or IS 2062, are a cost-effective choice for low-pressure applications, non-critical water lines, and light-duty structural connections. They are generally not recommended for high-pressure or elevated-temperature oil and gas service.

Can Plate Flanges be custom machined to non-standard dimensions?

Yes. Since Plate Flanges are profile-cut directly from steel plates, we can manufacture custom outer diameters (OD), inner diameters (ID), and bolt-hole configurations, including AWWA, BS, and other international standards, to match existing equipment and project requirements.
