ASME B16.11 A182 UNS S32750 Super Duplex S32750 Tee

Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature Above 50¡ãC .

ASTM A240 Type 2205 Plate is a duplex stainless steel plate that is used extensively in various industries such as chemical processing, oil and gas exploration, and marine engineering. SA 240 GR 2205 Sheet is made from grade 2205 stainless steel, which is a combination of ferritic and austenitic steel.

A789 UNS S31803 and UNS S32205 are two grades of duplex stainless steel that are widely used in various industrial applications. These Duplex S31803 Seamless Pipes are known for their excellent corrosion resistance, high strength, and good weldability. A789 is a specification that covers seamless and welded tubes made from duplex stainless steel.

It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing.

The flange a182 f53 can also differ in the face type as flat face, raised face and ring type joint flanges.

UNS S32750 Flanges are used in seawater piping, desalination plants, mechanical components, high-pressure RO plants, etc. SD pipe flanges are used in heat exchangers, service and process water systems, offshore platform, oil & gas industry, etc. These flanges are also found in line pipes, power industry FGD system, industrial & utility scrubber, absorber tower, pressure vessel, etc.

Super Duplex UNS S32750 is the most common Super Duplex grade on the market. UNS S32750 is a duplex stainless steel designed for use in corrosive chlorine-containing environments. It has very good localized corrosion and stress corrosion cracking resistance and high mechanical strength. Widely used in oil and gas, hydropower, pressure vessels, pulp and paper, structural parts and chemical tankers.

Super Duplex 2507 Lock Washers has excellent corrosion resistance in marine environments.Lock washers are designed to be tightened to a required torque beneath an ordinary fastener. They exert a spring tension that keeps the fastener from vibrating loose. They are often attached to the nut side of the fastener.

The mechanical strength, corrosion resistance and low temperature toughness of the ASTM A182 F53 Flanges is higher than that of ordinary duplex stainless steels.

Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance.

This is the main reason why Super Duplex Flanges note an improvement of tensile strength over ferritic and austenitic steel grades.

HT PIPE is the government certified and doing business in steel industry for long years and are manufacturing S32750 Duplex buttweld fittings at affordable rates.

S32760 Heavy hex nuts are slightly larger and thicker than standard (finished) hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts.

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.

Alloy 2205 Pipe has a melting point of 1350 degrees C. These pipes have a wall thickness between 0.3mm to 50mm.

The standard duplex material consists of 22% chromium, 4.5% nickel, 3% molybdenum, manganese, silicon, nitrogen, phosphorus, carbon and sulfur. Duplex 2205 screws and other fasteners have minimum yield strengths up to 97ksi and minimum tensile strengths up to 131ksi. Duplex 2205 hex bolts are nearly twice as strong as austenitic grade steel bolts. They have higher mechanical properties, so 1.4462 alloy 2205 studs and other types of bolts can meet different specifications such as ASME SA 182, 240, 479, 789.

Hex head bolts are ideal for many types of industrial fastener applications. The six-sided design of the 2205 Hex Bolt allows the bolt to be tightened or loosened quickly and efficiently, improving overall work speed and quick turnaround. Some additional benefits associated with using UNS S32205 Hex Bolts (also known as S31803) include: Extremely strong, hot forged, ASTM A449 and SAE J429 specified, improved corrosion resistance.

The higher percentage of chromium in the alloy of duplex stainless steel seamless pipe makes it resistant to oxidation.

ASTM A240 Type 2205 Duplex Sheet provides a maximum Brinell hardness value of approximately 290 in the annealed condition.

Designers may have the option to reduce the wall thickness of the duplex 2205 welded pipe, because of its high yield strength. The yield strength of this material is almost two times that of the usually used austenitic stainless steel grade. Unlike austenitic steel pipe, the Duplex 2205 Tube may at times exhibit magnetic behavior because the microstructure of its alloy contains about 50% ferrite.

The A182 F51 material has carbon, 2% manganese, phosphorus, sulfur, 1% silicon, chromium, 4.5% nickel, 2.5% molybdenum and nitrogen it.

Super duplex steel flanges are very good for servicing a severe corrosive atmosphere like offshore and marine applications.

The 2507 pipes could also be electric fusion welded. The Pipes Manufacturer comes under five different classes with each class having a special mechanical property setup. The electric resistant welded pipes are stronger and they could be used for extensive welding.

2507 has good weldability and workability, and it’s widely used in desalination equipment, chemical process pressure vessels, piping and heat exchangers.

These super duplex fittings products are designed in accordance with national and international standard specifications. These Super Duplex Steel S32750 Seamless Fittings and Super Duplex Steel S32750 Welded Fittings are widely used in various application industries such as automotive, chemical, marine, power plants, heavy engineering, etc.

Astm A790 Uns S31803 grade pipes and tubes can be cold-rolled to give them enhanced properties and good resistances in different systems.

On average, duplex stainless steel is about twice as strong as either ferritic or austenitic stainless steels. High toughness and ductility. Duplex stainless steel can be more easily formed under pressure than ferritic grades and also have superior toughness.

Although when the 2205 duplex stainless tubing material has been exposed to temperatures above 572¡ãF, even when the exposure is for a short period of time, the duplex 2205 seamless tube is subject to embrittlement.

The ductility and corrosion resistance of duplex steel fasteners are reminiscent of their austenitic microstructure. On the other hand, the toughness and hardness of these fasteners are inherited from the ferritic region.

Duplex stainless steel, famous for its excellent combination of good mechanical properties and high corrosion resistance, is widely used in the industrial fields, such as the production of seawater heat exchangers and the chemical containers for use in the high-concentration chloride environments.
