We are also a supplier and exporter of Alloy Steel ASTM A182 F5 Butt Weld Flanges for high pressure hydraulic systems.

The alloy has great mechanical properties at subzero temperatures.For catering to the needs of our customers better, it is essential that we manufacture Monel Pipe Fittings in different types, with each one serving some specific purpose.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

A335/SA335 materials are used in a wide variety of plants and processes worldwide, including refineries, power plants, petrochemical plants, hydrocrackers, cokers, high temperature and ultra-high temperature lines, reheat lines, distillation, oil field service, and more.

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.

A182-F11 has high thermal strength (¦Äb¡Ý440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion.

The rim has numerous holes drilled into it that enables the flanged to be attached to a bolted flange. This design is far better because of the structural valve.

Alloy steel is divided into two categories: high-alloy steel and low-alloy steel. Low alloy steel flanges, on the other hand, contain about 0.05 ¨C 0.25% carbon and up to 2.0% manganese.

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

A335 grade P5c pipe is a low alloy carbon steel (Cr-Mo) self-quenching in air where high hardness and residual stress are required for welding and it is not recommended for direct use in services requiring critical conditions. This situation requires the application of post weld heat treatment (PWHT). If you want to avoid PWHT then you can use preheat (120¡ãC) when soldering A335 grade P5c tubes. PWHT is required if the thickness of ASTM A335/ASME SA335 P5c alloy steel pipe is greater than 13 mm.

We offer F9 Alloy Steel Flanges that have superior corrosion resistance and ductility due to the small amount of Chromium and Molybdenum. A182 F9 Alloy Steel Flanges is for use in small size and high pressure piping systems. Due to the small amount of chromium and molybdenum it has superior corrosion resistance and ductility.

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

Low alloy steel ASTM A182 F11 flanges typically have a total alloy content of 1.5% – 5%. Its common alloying elements are manganese, chromium, silicon, nickel, molybdenum and vanadium. It may contain up to four or five different quantities of these alloys. At the same time, the increased strength of the alloy steel F11 flange may require higher forming pressures. Annealing of SA 182 Gr F11 steel flanges is accomplished by water quenching by thorough immersion at 1725¡ãF – 1850¡ãF (941¡ãC – 1010¡ãC) and can only be hardened by cold work.

Alloy steel pipes are common in applications involving automobiles, kitchenware, and industrial equipment. Typically, superalloy steel boiler tubes are used in applications with ambient temperatures exceeding 500¡ãC. For example, hollow and thin-walled alloy steel drill pipes must be able to resist pressure differences that manifest between the inside and the outside of these alloy steel seamless pipes.

Chromium increases the tensile, yield and hardness of steel at room temperature. This is why ASTM A335 chrome-molybdenum alloy seamless steel pipes are mainly used in power plants, refineries, chemical plants and oilfield platforms where fluids and gases are transported under extremely high temperatures and pressures.

Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.

Alloy seamless steel pipes are mainly used for high pressure and high temperature pipes and equipment such as power plants, nuclear power plants, high pressure boilers, high temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel, processed by hot rolling (extrusion, expansion) or cold rolling (drawing).

These are used in applications where the resistance required is not much and general corrosion resistance is required.

The composition of the chrome-molybdenum alloy steel pipe in A335 makes it ideal for power plants, refineries, petrochemical plants and oilfield services that transport fluids and gases at extremely high temperatures and pressures.
