Astec tubes are a trustworthy manufacturer and supplier of stainless steel, carbon steels, Hastelloy steels, etc. We maintain the superior quality of Alloy Steel WP91 Pipe Fittings. This particular grade is well known for its great performance in high pressures. They are widely used in making the attachments between the pipes or valve for ensuring no leakage in all critical conditions. It has splendid welding and cold working properties. The specifications and dimensions of this alloy steel are manufactured in adherence with ASTM / ASME A/SA 182, ANSI/ASME B16.11 and BS3799, etc. It provides elongation to 20%. The general chemical composition of this alloy is consisting 0.02% sulfur, 8.5 o 9.5 % chromium, 0.85-1.05% molybdenum, 0.08 to 0.12% of carbon, 0.3 to 0.6 manganese, 0.5% silicon, and 0.01% phosphorus. Grade F19 showcase great versatility, machinability, higher impact properties, long wear life span and grain-refining. Our Alloy Steel WP91 Pipe Fittings are widespread in the engineering and textile industries. It is also preferred in non-critical jobs like cooling systems and fire protection systems.
They are also widely used in the construction of the chemical plant, vessels, pipework and also applied to structural hollow sections and pressure purposes, etc. Other than this, the Pharmaceuticals, Chemical Equipment, Sea Water Equipment, Heat Exchangers, Condensers, and Pulp and Paper Industry make great use of it. In general, grade 791 can be in socket weld or threaded weld. Socketweld is mostly used for absorbing high pressures but for small or nominal pipes. Likewise, Threaded forging is the type of pipe fittings used for less costly and non-critical works. They are easily identifiable from their appearances. If you find threading on the inner lining surface of the fitting then it is threaded. Similarly, if the surface is all clean and polished then it Socketweld fitting.
