As an acclaimed endeavor of the business, Calico Metal are included in offering an unfathomable exhibit of Stainless Steel 347/347H Pipes and Tubes as a producer, exporter, stockiest and supplier to our residential and worldwide clients. As driving maker and exporter of 347/347H Stainless Steel Pipes and Tubes (too known as WNR 1.4550/1.4961 Pipes and Tubes), we have been extended our business sector system all through the world so that our items have been come to in the abroad commercial center. 347H Stainless Steel is variant of the basic austenitic 18/8 Grade 304 with added Columbium - the introduction of Columbium stabilizes the steel and eliminates carbide precipitation which subsequently causes intergranular corrosion. The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures.

As for national and universal nature of crude materials, we additionally offer these SS 347/347H Pipes and Tubes (likewise perceived as UNS S34700/S34709 Pipes and Tubes) in tweaked sizes and thicknesses according to particular requests by our regarded customers at business sector driving costs. These are accessible in various determination and measurements according to the customers necessities. These are generally utilized as a part of different application industry, for example, oil & gas, chemical industry, conveying water and other fluids etc. We offer to our customers at exhaustive scope of Aluminum Round Bars & Rods at extremely reasonable prices. Calico Metal manufactures, supply and export Stainless Steel Pipes in austenitic, duplex and nickel alloy seamless and welded steel pipes both from coil and from plate. During continuous production from coil, in one single operation the base material can be formed into a pipe, welded, heat-treated and subjected to non-destructive testing. All pipes are pickled and passivated in our 13 meter long with outsourced pickling facilities.

The stainless steel pipes can be manufactured in fixed lengths & random lengths between 4 & 12 meter. Stainless steel Pipes with an outside diameter between 6" (168, 3 mm) and 80" (2032 mm). Calico metal stocks Stainless steel pipes and standard piping which is ordered in accordance with ASME/ASTM SA/A312 with dimensions and weights in accordance with ASME B36.19. ASME B 36.10 available on request. Calico Metal material range includes high performance austenitic stainless steel, high temperature austenitic stainless steel, duplex & super duplex stainless steel and nickel alloy grades. The pipes can be produced in single random or double random lengths. Furthermore Calico metal has fully automatic welding equipment to make circumferential welds to enable the supply of double random lengths with a maximum length of 12 meter. Both 347/347H are used primarily in elevated temperature applications.

Applications
