Rajendra Pipe Fittings is a producer and retailer of ASTM A182 Gr F321/321H Socketweld Fittings which is recognised by industry. The ASTM A182 Gr F321/321H Socketweld Fittings we produce are made from the highest quality raw materials and are in compliance with global and regional quality requirements. The ASTM A182 Gr F321/321H Socketweld Fittings, the right blend of nickel, chromium, and titanium, provide a high resistance to corrosion and oxidation. The ASTM A182 Gr F321/321H Socketweld Fittings are designed to provide better efficiency even at low temperatures, and at high temperatures. Such coils will carry temperatures of as high as 870 ° C. The ASTM A182 Gr F321/321H Socketweld Fittings offer excellent properties in manufacturing and machinability. At Rajendra Pipe Fittings, we are revered to offer the highest quality items that meet the needs of our customers. Therefore, we are undertaking extreme quality checks for our goods.
The ASTM A182 Gr F321/321H Socketweld Fittings are well suited to hardening by cold working. For the ASTM A182 Gr F321/321H Socketweld Fittings, which is at least five times the carbon content, the component level of carbon can be shown by the sum of titanium content. These fittings have strong weldability properties and usually no need for post-welded annealing. The ASTM A182 Gr F321/321H Socketweld Fittings are not prone to intergranular corrosion after heating within the 425-850 ° C carbide precipitation range. The ASTM A182 Gr F321/321H Socketweld Fittings are not well finished, and are considered to have strong resistance to subsequent aqueous corrosion. The ASTM A182 Gr F321/321H Socketweld Fittings can be used at higher temperatures in most diluted organic acids and at lower temperatures in pure phosphoric acid and with solutions diluted at elevated temperatures up to 10 percent. ASTM A182 Gr F321/321H Socketweld Fittings provide greater properties for creep and tension break. Applications of the ASTM A182 Gr F321/321H Socketweld Fittings are large and require the manufacture of exhaust manifolds and expansion joints for the aircraft. Tubing of heating elements, heat exchangers and thermal oxidizers are made with ASTM A182 Gr F321/321H Socketweld fittings because they give high heat resistivity. These Fittings are used in the manufacturing of Pharmaceutical Equipment, Chemical Equipment and also used in Pulp and Paper Industry.
