ASTM A182 / A240, Stainless Steel Weld Neck Flange Suppliers, Manufacturer, Exporter, Stockist in India.

Steel Sales Company is one of the main producer, provider, exporter of ANSI B 16.5, ASME B 16.47 Stainless Steel Weld Neck Flange, ASTM A182 SS Weld Neck Flanges, SS Raised Face Weld Neck Flanges, ASME SA182 Stainless Steel WNRF Flanges, ASTM A182/A240, Stainless Steel Weld Neck Flange in India. Compound Steel Weld Neck Flanges are welded to the base of the channel. The bore of the flanges coordinates the bore of the pipes, therefore permitting undisturbed item stream and lessens the turmoil and disintegration at the joints as well. Weld Neck Flanges are joined to one another by jolts and are joined to the channeling framework by welding or interweaving. We hold a gigantic bunch of Steel Welding Neck Flanges. This is expected to be joined to a directing system by buttwelding. It is commonly expensive because of Its long neck, anyway, it is supported for high weight applications. The neck, or center, transmits stresses to the base of the center to the divider thickness at the butt weld, giving significant fortification of the flange. Steel Welding Neck Flanges stock as indicated by ASTM A182, ASME B16.5 dimensional guidelines. These spines can be acquired by us in redid sizes and measurements regarding national and global principles.

Flanges are connection bolsters utilized in a pipeline to attach two significant pipelines. With the mechanical help of the flanges, a consistent equipment design can be provided to the pipeline. For supporting a more prominent mass, a heavier rib body is required. The basic quality given by the flanges is an incredible architectural strength required in the pipeline structure.

Flange Facing
  • Raised Face: The concept of raised face is to establish more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint.
  • Ring Type Joint: They are applied for high pressure, high-temperature application with an “initial line contact” mechanism served by the metallic ring gaskets.
  • Flat Face:  Mostly flat facing is applied on flanged ends, which are produced from castings or fiberglass. Flat Face flanges are never to be bolted against a raised face or any other.
  • Male Female Joint: They are commonly used for high pressure and high-temperature services
  • Tongue and Groove: Prominently found on flanged pump covers and valve bonnets. Also used for high temperature and high-pressure applications

Production Of Flanges

We have world-class machinery for flanges manufacturers. We have CNC, Lathe Machines as well as punch dyes required for manufacturing of flanges. The forgings are outsourced. We have in house testing facilities like Spectro machine, PMI Machine, Mechanical test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge. Our product range also includes pipe fittings and fasteners which are considered piping accessories for a pipeline set up. The production Raw material is subject to heat-treatment for optimum use of a dye for processes ahead. Then the flanges are made as per dimensions specified in the ANSI Standards with a hub or without the addition of the hub. Then the flanges are machined and finished and then the marking process of the flanges is done.

Quality Control:

Steel sales Co is certified by all the renowned certificates including ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007 & CE-PED 97/23/EC. We guarantee the best quality for all the fittings manufactured as they are checked in the workshop for defects in quality and technique. Our quality program is a 3 step independent department check for various factors, including Dimensional Check, Visual Inspection, and Finishing, Burr level, Leakage Test, Pressure Rating test, Chemical inspection, and Mechanical properties verification.


All the suppliers get marked with a standard format of an individual heat number. This heat number is fully detectable to our records and we keep a rigid watch to guarantee the credibility of our image isn't copied by different brands.
