A/SA387 GR 9CLASS 2 Weldable carbon steel plate for high temperature pressure vessels and boilers. The material benefits from added chromium and molybdenum, which give the steel better corrosion and heat resistance. A/SA387 Grade 9 is intended for use by manufacturers serving the oil, gas and petrochemical industries.

These fittings are available in different types such as elbows,couplings,tees crosses,plugs,pipe nipples etc.

Commercially pure wrought Nickel with good mechanical properties over a wide range of temperature and excellent resistance to many corrosives, in particular hydroxides.

Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions. Outstanding resistance to caustic alkalis up to and including the molten state. In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidizing salt solutions severe attack will occur. Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to 550C. Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in de aerated acid.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

Astm a335 P91 pipe is a seamless pipe for high temperature applications. These pipes are made of ferritic alloy steel. Chemically speaking, a335 P91 welded pipe contains elements such as molybdenum (Mo) and chromium added to the alloy. The tensile strength of sa335 grade P91 pipe increases when molybdenum and chromium are added to the alloy. The tensile strength of a335 grade P91 pipe is 415 Mpa, while its yield strength is 205 Mpa. Pipe elongation ranges from 20% to 30%.

High alloy steel is defined by a high percentage of alloying elements.

Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ? inches through 48 inches of nominal diameter sizes of flanges.

Unlike the bends, the elbows can reduce the pressure applied on the walls when turning the fluid flow direction.Fittings made from WPHY 52 material are known to have a long work life, durable, tough and hard. The WPHY 52 properties make these fittings a perfect cost saving solution for a variety of industries.

Bolts are chrome molybdenum heat treated steel according to ASTM A193 B7m specification for bolts. The primary alloy components of ASTM A193 Grade B7 bolts are chromium and molybdenum. These ASTM A193 B7 Metric Bolts are manufactured by heat quenching and tempering. Heat treating A193 B7 bolt material helps to develop desired mechanical properties such as increased tensile strength of ASTM A193 B7 hex bolts after heat treatment.

The Alloy Steel Blind Flanges are used to close a pipe connection. There are different types and grades of the blind flanges as well.

These supplied alloy steel F2 A182 bars are manufactured synchronously through set industry specifications using high quality raw materials and leading technology. Regarding the domestic and international quality of the raw materials, we also offer these round bars and bars in custom sizes.

Chromium-molybdenum alloy steel has strong crack resistance under high temperature and high pressure. Chromium molybdenum is also resistant to hydrogen attack and hot sulfide corrosion cracking.

These Alloy Steel F12 Lap Joint Flanges are made up of in dissimilar grades of standard ranges and meet its terms through national and international standards. Alloy Steel ASTM A182 F12 flanges are exceptionally resistant to corrosion in nature. In the interim, fabricators can cut pipe to length without inconvenience for these ASTM A182 F12 Alloy Steel flanges.

ASTM A193 Grade B7 bolts are considered for applications up to 450¡ãC due to heat treated chrome molybdenum steel. B7 stud bolts are bolts with male threads and a hex head designed to be actuated by a wrench. It can be fully threaded or partially threaded and is supplied with a hex cap.

Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC.

Alloy steels are used in a range of demanding applications in the aerospace and power (nuclear) industries. Adding other elements gives alloy steel extra strength.

SA 182 Socket Weld Flanges are joined by inserting the pipe into the socket end and applying a fillet weld around the top. This allows for better flow of fluid or gas inside the pipe and smooth holes.

The minimum yield and tensile strength requirements for ASTM A193 Grade B7m bolts are reduced compared to Grade B7 bolts. ASTM A193 B7 heavy duty hex bolts are readily available in the market. Therefore, A193-B7 studs are used in many applications due to their easy availability. ASTM A193 B7 Studs are commonly used in pipe flange connections and construction.

ASTM A335 grade P91 tubing contains small amounts of other alloys such as aluminum, niobium, nickel, nitrogen, titanium, vanadium, and zirconium. These pipes are based on the A335 standard, but when forged or drilled, the pipes can also meet the A369 standard. These pipes have a minimum yield strength of 415 MPA and a minimum tensile strength of 585 MPA.

Although acceptable fouling levels are considered beneficial to the alloy, in moderate cases, fouling deposits on Astm A182 F9 flange surfaces can act as a barrier to excessive corrosion. When flanges are produced using specification ASTM A182, they work well at high temperatures, albeit in applications with high pressure.

Weld Neck Flange is expensive because of its long neck and cost of people for contact WN flange with pipeline or fitting but is preferred for high-stress applications. The necks, or hubs, transmits stresses to the pipeline.
