STAINLESS STEEL FLANGES : PRODUCT

Stainless steel flanges is an iron based metal. Stainless steel flanges are normally chosen for their high resistance to corrosion and its high-temperature strength. Although they are chosen for their resistance to corrosion does not mean they are immune to it. Stainless steel flanges also show other characteristics like ductility and toughness which should be taken into consideration. Different types of stainless steels show considerable variations depending on a combination of its chemical composition and the aggressiveness of the environment.We manufacture flanges from sizes ½” to 36″ and in dimensions from 15mm to 600mm.

STAINLESS STEEL FLANGES : TYPES

Stainless steel Flanges can be declassified into various types:

  • SS Blind Flange
  • SS Weld Neck Flange
  • SS Socket Weld Flange

PRODUCTION OF STAINLESS STEEL FLANGES

We have world class machinery for manufacturing Stainless Steel Flanges. We have CNC, Lathe Machines as well as punch dyes required for manufacturing of  Stainless Steel 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 dye for processes ahead. Then the  Stainless Steel Flanges are made as per dimensions specified in the ANSI Standards with hub or without the addition of the hub. Then the  Stainless Steel Flanges Manufacturers are machined and finished and then the marking process of  Stainless Steel Flanges is done.

STAINLESS STEEL FLANGES : BRAND

Stainless Steel Flanges Suppliers manufactured are marked with the standard format of i-FIT-Size-Material-Heat Number. This heat number is 100% traceable to our records and we maintain a strict watch to ensure the authenticity of our brand so that it’s not duplicated by other brands.

PACKING & DOCUMENTATION OF STAINLESS STEEL FLANGES

Instinox Stainless Steel Flanges suppliers are packed in special and branded carton boxes and crate boxes depending on the mode of transport. Flanges are wrapped with special thin plastic and beveled ends are protected with plastic caps. They are then packed in the carton or wooden boxes. Socket weld ends are also protected by the caps for protection to the ends and the threads where applicable. It is important that the damages in transit are avoided and pipe fittings reach the customer in the same form as it is manufactured. Thus, we place a lot of emphasis on packing and packaging of the goods. Flanges carry various export documents such as the commercial invoice, packing list, Test Reports, HS Code, Country of Origin attested by the chamber of commerce, Fumigation Certificate, Warranty Letter, and Base Material Certificates. Each heat and lot of tube fittings are supplied with a material test certificate as per EN 10204 NACE 3.1 standards indicating the chemical and mechanical properties of the pipe fittings along with pressure rating. We also confirm the guarantee of the fittings supplied as per Purchase order specifications and attest the same in the Material Test Certificate. We also welcome any third party inspection from an agency nominated by the customer to comply with NACE 3.2 Certification if required by the customer at an extra cost.Free samples in Stainless steel and carbon steel can be provided upon request to gauge quality and finishing of our Flanges against confirmed receipt of purchase order.
