Stainless Steel Flange

A blind flange is a solid flange without holes or threaded holes used to close the end of a pipe, fitting, valve or equipment. Blind flanges are also used in pressure test equipment. Blind flanges are available in two types: convex and flat.

The most popular material grades are made of carbon steel. HT PIPE not only offers carbon steel pipe flanges and flange fittings, but we also offer stainless steel flanges for a variety of projects. Plate flanges can be ordered for waterworks and petrochemical applications. Bar flanges and forged gauge flanges can also be manufactured to the dimensions in our catalog.

There are various austenitic and ferritic flanges on the market. Ss Flange also known as stainless steel flange is one of them. Stainless steel pipe flanges are available in a variety of grades with widely varying mechanical properties. Due to their corrosion resistance, these stainless steel pipe flanges are used in acid and fertilizer production plants. Stainless steel flange manufacturers in India recommend these flanges because of their resistance to stress-related corrosion cracking. Ss 316 plate flanges are austenitic grade flanges with high molybdenum content.

Cross-contamination can corrode the stainless steel square flange base metal, resulting in discoloration of the finished product. Post-weld annealing is recommended for stainless steel 304 sliding flanges. Additionally, cold working of Oatey stainless steel flanges increases tensile strength and hardness. The flanges show a typical tensile strength of 75,000 psi 515 MPa and a yield strength of 30,000 psi 205 MPa. Ansi B16.5 Uns S30400 butt weld flanges can be conventionally hot worked.

However, it should be limited to 927 degrees Celsius and should not go below that. The ideal temperature for hot working stainless steel floor flanges is between 1149¡ãC – 1260¡ãC. For optimum corrosion resistance, stainless steel blind flanges require post-work annealing. These Astm A182 F316 blind flanges are also available in different pressure classes. Werkstoff No 1.4301 lap flanges are used in the chemical, energy, power, medical and petroleum industries.

HT PIPE provides you with all the whereabouts of these stainless steel flanged tees and helps you choose the Ss 304 puddle flange that best suits your goals. With our expert staff dedicated to the field, you will have no problems purchasing, delivering or installing your product.

These parts could be used in an as welded condition, despite not receiving annealing treatment. In many applications, the use of a UNS S31600 SS 316L Flange offers easy access to a worker for purposes including cleaning, inspection or even modification. Industries such as pharmaceuticals, which require sanitary alloys for the manufacture of their products prefer the use of ASTM A182 F316L Stainless Steel Pipe Flanges.

The flanges are used in a variety of applications for different purposes. The Stainless Steel DIN 1.4307 Blind Flanges are used to end a pipe by closing the connection. The flanges come in different dimensions, specifications and standards. The sizes range from ? inches to 48 inches in nominal bore size.

Threaded flanges are used with pipes that have external threads. The benefit of these flanges is that it can be attached without welding. Threaded flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these flanges are highly demanded

Threaded flanges, also sometimes referred to as companion flanges / screw flanges / NPT flanges, contain a female NPT thread in the center for connection to male NPT threaded piping. Threaded flanges are common when creating reducing connections. Other thread styles are available for machining, aside from the standard NPT form as designated by the ASME B16.5 specification.

Weld neck flange and long weldneck flange provide reinforcement in application requiring high pressure and during low and high pessure extremes. It also helps in low cycle fatigue caused by line expansion of other variable forces. Weldneck flange bore is machined to match the ID of the pipe or fitting.

The absence of higher carbon content in the alloy of ASTM A182 F316L Flange does not foster the formation of carbide precipitates on the grain boundary. Furthermore, these components have no requirement of annealing treatment

ASME SA182 SS 347 Slip-On Flanges are used with heavy wear exhaust systems and tubes connecting industrial boilers as they are resistant to high oxidation and impart greater toughness at cryogenic temperatures.

these have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in this environment..

All our Stainless Steel 317 Flanges conform to relevant material and dimensional specifications and can be supplied complete with material certificates to EN 10204 3.1.

SS 317 / 317L Flanges, which is available in different sizes and shapes to our esteemed clients. These Stainless Steel 317 Flanges is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum.

We are a manufacturer, supplier and exporter of ASTM A182 Stainless Steel 317 / 317L Flanges which are offered after a variety of surface treatments that only add to their versatility.

321H Stainless steel Flange is a modification of 321 steel flange with a higher carbon content, to provide improved high temperature strength.

Our UNS S31700 SS Orifice Flanges are molybdenum bearing, that combat pitting and act as leak-proof seals to pipe endings in the breweries, water and sugar industry. Our Stainless Steel 317 Slip-On Flanges with the Chromium-Nickel-Molybdenum combination imparting it reliable sturdiness at high temperatures and offer an unmatched degree of fabricability and formability, thus securing themselves as the top choice in the aerospace industry and at Steel Plants.

Stainless Steel Flanges are designed with care using current techniques under the visionary guidance of accomplished professionals at manufacturing unit. Offered range is stringently tested on various parameters of quality for ensuring flawlessness and defect free. These products are widely used in various industries and widely appreciated by clients for owning unmatchable characteristics. Offered range supplied in quality assured packaging material.

There are different grades of the 304L depending on the carbon content. The Stainless Steel 304L Flanges are made up of the same 18% chromium, 8% nickel but with a lower carbon content than the 304 flange material.

Stainless Steel Blind Flanges are mostly used to seal the end or opening of a pipe, which is why they come without a bore. This comes in handy for inspection and pressure tests, as it allows quick access to the pipe.

The A182 F304L WNRF Flange is a weld neck raised face flange. It belongs to the specification A182 which is a specification for the forged and rolled alloy stainless steel flanges, fittings, valves and high temperature service parts

Bleed rings provide a convenient way of draining piping, taking samples, attaching instruments or even bleeding of a valve. Unified Alloys stock bleed rings in stainless steel and other corrosion resistant material options.

The weld neck provides extra grip while the raised face provides extra surface for attachment. These flanges are also strong with 205MPa minimum yield strength and 515MPa minimum tensile strength. The?SS 304L SORF Flange?is a slip on raised face flange made in the 304L material.

The 304L Stainless Steel Flange Pressure Ratings differ ranging from 150 to 2500 and PN6 through PN64. The temperature tolerance is also high for these flanges and they can operate at up to 870 degrees Celsius.

Components constructed under specification ASTM A182 such as 317L Stainless Steel Flanges are intended to be used for elevated temperatures. This specification takes into account various requirements that these flanges need to conform to. Usually, similar to most ASTM specifications, the ASTM A182 have to conform to both mechanical and chemistry as well as test methods

Our UNS N08904 Stainless Steel Blind Flanges are widely used to close the tail of pipe of a pressure vessel, as they are designed to retain pressure in a high-pressure area, and are resistant to reducing acids like sulphuric acids in petrochemical plants and oil refineries.

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure “Tappings”, mostly on 2 sides, directly opposite each other, are machined into the orifice flange.

Grade 310s Stainless Steel Flanges is readily available for applications in the industrial, architectural, and transportation fields. Grade 310s also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
