Our ASTM A182 F5 Alloy Steel Blind Flanges are square and can be used to connect pipes of nominal bore size without welding and are suitable for high pressure hydraulic systems.

These are also added with limited amounts of elements like sulphur, silicon, manganese and phosphorous that helps in increasing ¨C Hardness, Strength, Chemical resistance, and more.

They can also be seamless in nature. The nominal diameter of the seamless fittings ranges from ? inches to 24 inches and the welded fittings range from ? inches to 120 inches in diameter.

Forming operations such as bending and flanging, as well as fusion welding, are well suited for ASTM A335 p11 alloy steel pipe. The specified tests for alloy steel seamless pipes include flattening test, bending test, hardness test and longitudinal or transverse tensile test.

The ASTM B366 Pipe Fittings that we, Steel Tubes India, manufacture, are covered under the specification for nickel alloy pipe fittings and these include the likes of Hastelloy, Inconel, Nickel Alloy and Monel.

ASTM A193 Grade B7 bolts are made of chrome-molybdenum material with high tensile strength and good elongation properties.

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.

We are a manufacturer, supplier and exporter of Alloy Steel ASTM A182 F5 Flanges, which have gained overall positioning in several piping systems. Our range of alloy steel A182 F5 slip flanges includes all types of conventional and custom flanges to ASTM A182 specification, alloy steel flanges for high temperature service.

ASME SA182 F5 pipe flange weight depends on wall thickness and nominal bore. The wall thickness of the flange is determined by the pressure rating.

Steel pipes are used in structures, transportation, and manufacturing. They are sized according to their outer diameter, with the inner diameter varying based on wall thickness. Some applications need thicker walls than others, depending on the forces the pipe must manage.

Alloy seamless pipes are processed by advanced machines and manufactured by hot and cold processing.

A182 F2 round bar has high strength, formability and hardenability.

ASTM A193 Grade B7 specification covers the requirements for high strength alloy steel bolting materials for high temperature or high pressure service and other special purpose applications. It is a standard specification that defines typical chemical composition, mechanical properties, hardness requirements, preferential heat treatment, product marking, certification, and other requirements for bolted connections used in pressure vessel service, valves, flanges, and fittings. ASTM A193 defines SI (metric) and inch-pound units.

Manufacturers must adhere to the chemical composition used to produce ASTM A182 F11 Class 2 equivalent grades. Alloy Steel Different alloying agents used in ASTM A182 F11 RTJ flanges, such as phosphorus, silicon, nickel, carbon, manganese, chromium, molybdenum, niobium, titanium, improve fitting performance.

ASTM A335 P91 grade pipe is a high quality pipe for high pressure boilers. P91 tubing is ideal for bending, flanging or for welding and similar operations. The material of steel should adhere to the requirements of chemical composition, tensile properties and hardness.

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.

L7 threaded studs and short head bolts are readily available in the market.

It is the addition of other elements that make alloy steel stronger. Heat-treated elements such as silicon and manganese give alloy steels improved properties and additional benefits, such as increased corrosion resistance or improved weldability.
