In addition to good corrosion resistance, the addition of chromium and molybdenum to the alloy enhances its ductility.

Alloy steel grade 2H gaskets are further cut, hydrotested, annealed, straightened and pickled. The manufacturing process of our Alloy Steel Grade 2H Split Gaskets is carried out in a state-of-the-art production facility under the proper supervision of industry experts.

ASTM A182 Gr F9 flanges are typically designed for applications with high temperature requirements. Alloys used to produce flanges according to this specification include wrought or rolled alloys and several stainless steel grades.

800H can resist corrosion of many corrosive media. Its high nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content provides better resistance to pitting and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance in sulfuric acid and hydrochloric acid. Good corrosion resistance in oxidizing and non-oxidizing salts, in addition to the potential for pitting corrosion in halides. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.

There are different types of fittings such as bends, tees, crosses, reducers, caps and the WPHY 52 Elbow.In sour service wells, when hydrogen sulphide gas reacts with water, the hydrogen molecule gets deposited either on the pipes or fittings.

ASTM A182 Alloy Steel Pipe Fittings are very easy to install and have a low hub due to the pipe going into the fitting before welding.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

A182 threaded flanges are primarily used for utility services such as air and water. It is similar to a Slip-On flange, but the holes are threaded.

ASTM A182 Low Alloy Steel flanges as well as the other types of alloys. The ASTM A 182 specification specifies flanges for high pressure services.

ASTM A182 F5 flanges are ready for industrial, construction and transportation applications.

ASTM A194 bolts include metals such as manganese and silicon, with additions of phosphorus, sulfur, and carbon. ASTM A194 gr 2h bolts are suitable for high pressure or high temperature service, or both. Further machining is possible by centerless grinding or cold drawing.

The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.

Although the properties of the fitting depend on the alloy used to manufacture them. Another process that improves the mechanical properties of ASTM A182 F9 Alloy Steel Flanges is the forging process. These Grade F9 Weld Neck Flanges can also be reused and are meant for high pressure applications. This is the reason as per the specification they have to be rolled or forged.

ASTM A335 seamless steel pipe is commonly referred to as chrome molybdenum pipe with chemical elements molybdenum and chromium. Molybdenum can improve steel properties such as strength, elastic limit, wear resistance, impact resistance and hardenability.

The high chromium content gives these alloy steel socket weld flanges very good resistance to moisture erosion, which also contributes to their high temperature strength and resistance to scaling at high temperatures.

They have a minimum yield strength of 105ksi. There are different types of bolts and bolts for different types of applications such as ASTM A193 gr b7 hex bolts.

When connecting these parts, put gasket in the middle of two flanges, then tightening the flange screws, so the two will be connected together tightly.

We use state-of-the-art technology to precisely manufacture flanges such as ASTM A182 Class F5 Socket Weld Flanges. Buying an ASME SA182 F5 flange or any other flange from us will guarantee quality, economy and precision.

The carbon content of 4140 alloy steel pipe is 0.38-0.43%, the manganese content is 0.75-1.00%, the phosphorus content is 0.04%, the sulfur content is 0.04%, the silicon content is 0.15-0.35%, the chromium content is 0.8-1.10%, and the molybdenum content is 0.8-1.10%. is 0.15-0.25 % maximum in its composition. The material can be heat treated to anneal and normalize in air, or quench and temper in polymer or oil.

The ANSI B16.5 Alloy Steel Slip On Flange is a flange type that allows the pipes to slip onto the flange and makes the connection in a precise locations.

The Chromoly based F12 material specification are ideal for applications, where the piping systems are to transport or carrying corrosive fluids or gases at high-temperatures. Alloy Steel F12 Flanges they are used in various applications. Applications include chemical equipment, pharmaceuticals, gas processing plants, power generation tools, petrochemical industry, pulp and paper industry, on shore and offshore marine equipment, oil rigs, oil refineries, under water equipment, water desalination plants, condensers, heat exchangers and others.

The carbon content in the Sa182 F9 flange is lower, so the weldability of this alloy is much better. Generally, higher carbon content in alloys promotes intergranular corrosion, especially during high heat treatments such as welding.

Our alloy steel pipes are available in different sizes, grades, gauges and thicknesses according to customer’s custom requirements. We also supply these alloy steel LSAW pipes to our valuable customers at fairly reasonable prices.

After completion of manufacturing process, the manufactured product undergoes the process of Inspection. Which is one of the important aspects of metal forging manufacture, all the manufactured parts are being checked for defects under this process.

Alloy steel pipes are used in applications requiring moderate corrosion resistance, good durability, and economical cost. Simply put, alloy pipes are preferred in those areas where carbon steel pipes can fail. There are two types of alloy steel – high alloy steel and low alloy steel.
