Dinesh Industries > Stainless Steel Flanges

Stainless steel flanges manufacturer in India

Stainless steel flanges are used to blank off the ends of pipes and valves and can also be used on pressure vessel openings. In short, they are used to cut-off the flow to the pipe. ASTM A182 is the standard specification followed by stainless steel flanges manufacturers in India for various industrial sectors.

Those flanges are available in various size and standards to suit imperial tube, schedule pipe and spiral welded tube and they are designed are in specific applications. Stainless steel weld neck flange is designed to be butt welded to pipe and provide high strength, leak proof connection and used in high pressure area and where frequent dismantling is not needed.

  • Stainless steel slip on flange is designed to slip over the end of pipe and are then welded in place, they are easy to install and often used in low pressure area.
  • Stainless steel blind flange is designed to use to close off the end of pipe or valve and used in piping systems that needed to be isolated or maintenance is required.
  • Stainless steel socket weld flange is designed to be socket welded at the end of pipe which provide strong leak proof connections and applicable in high pressure area.
  • SS threaded flange is designed to be screwed onto the end of pipe and are applicable to low pressure area and are easy to install and dismantle.
  • Stainless steel lap joint flange is designed to be used in lap joint stub end, which is inserted into the flange and applicable food and beverage industry where frequent dismantling is required.
  • Stainless steel orifice flange is designed to be used in system where flow rate measurement requires, wherein small hole is there in centre of flange to insert the orifice plate, providing accurate measurement of the flow rate.
  • Stainless steel forged flanges combine two separate machinery parts together, which can be extension to a structure in order to make the object stronger and applicable to plumbing and mechanical industries.

Manufacturer of stainless steel blind flange & SS slip on flange as per ASTM A182/ SA 182, view grades and ready stock

The SS plate flange is essentially a ring or plate that has the inner diameter matching to the outer diameter of pipe so that it is attached to the pipe for other attachments to hold together. The stainless steel slip on flange is applicable to seamless pipes as it allows the pipes to slip through precisely and be welded at the connection. We are leading Stainless Steel Puddle Flange Supplier in Mumbai. The SS threaded flange has threads through which the connection is made. There are different manufacturing procedures such as the forging through which the stainless steel forged flange is manufactured. We encourage customers to inquire us with any requirements. We are Manufacturer and supplier of all kinds of stainless steel flanges in different specifications, standards and dimensions. Leading SS Flanges manufacturer in India.

Quality & Inspection

SS flange manufacturer follow quality control specifications and periodic inspections to assure its quality check of products manufactured. Besides mechanical test like, hardness test, tensile test, impact test, Visual inspection to check no forging scars and crack, scratches done which can reduce flange strength and connection reliability.

Dimensional check of stainless steel plate flange done using Calibrated caliper-scale, ruler and measure tape for inner and outside diameter, thickness, sealing surface diameter, flange neck diameter, bolt hole centre circle diameter, width of the sealing surface and other parameters. Also, the amount of eccentricity and ovality should be controlled against the determined tolerance. In Painted items, paint defects like pin hole, blistering, touch up and coating thickness to be check.

Shell pressure test is also applied on flanges in specific pressure and duration with water, Ex. 1.5-time pressure rating on 60, 120 or 180 seconds due to flange size with water containing corrosion inhibitor under 50°C, no visible leakage is allowed through the pressure boundary wall.

Positive material identification Test is performed on flanges to check the conformity of chemical composition of steel with reference standard of material. Marking check is an important final inspection part which includes mandatory information such as, manufacturer name and trademark, rating and material designation.

Also, size designation, threaded ends and ring-joint facing identification and permissible omission of markings being inspected. An ideal stainless steel flange tested and certified after QC inspection as per ASTM A182 is most trustworthy quality product. These SS flanges are suitable for long term uses in industrial sectors like oil and gas, chemical, petrochemical, food beverage, water-supply and treatment plants and many more.
