Biggest Supplier of Thick Wall Alloy Steel Tubing

Thick Wall Alloy Steel Tubing is used for very high pressure applications. These pipes have more than average wall thicknesses. These are used in petrochemical industries, nuclear power plants, chemical industrial applications and in oil and gas industry as well. The Heavy Wall Thick Steel Pipe is also used in research and development applications. The heavier pipes have their schedules numbered as EH, XH and XS. The pipes need to be double strong at times and the pipes are marked as XXS. The dimensions range according to ASTM, ASME and API standards and specifications. The outer diameters range from ½ inches to 36 inches. The heavy wall galvanized pipe is used for extra corrosion resistance.

Leading Manufacturer of large diameter heavy wall steel pipe in India

These pipes are also made from sheets, plates and coils. The seamless pipes are drawn from billets. The pipes also vary in forms such as round, hydraulic, square and rectangular. The length of the pipes vary from 3m to 18m and custom cut to length sizes. There are plain, beveled and treaded end types to the heavy wall hdpe pipe and other types. The pipes could be made up of any steel material and can have different strengths, corrosion resistance properties and heat resistance properties. The Thick Walled A106 Grade B Pipe are intended for high pressure high temperature services such as boilers, heat exchangers and in nuclear power plants. Depending on the material grade, the mechanical and physical properties vary as well as the prices.
