Gautam Tubes cater raw materials like ASTM A671 and process ASTM A 671 Welded Pipe & Tubes. We have a long track record for manufacturing welded pipes and tubes. We got expertise in producing high tensile welded pipe and tubes that are known for its prominent features. We also deal with other types of ferrous and non-ferrous welded pipes and tubes. In our inventory, we stock these pipes and tubes in various custom dimensions and surface finishes. We also offer nonstandard dimensions and provided machining allowances for multiple applications. Here we decrease possibilities of manufacturing defected pipes and tubes this is due to our well-organized manufacturing plants and manufacturing machines. We follow industrial set guidelines and norms to manufacture a superior level of products.
ASTM A671 Welded Pipe & Tubes do not have weld seam inside or outside of its surface. Mostly, welded pipes and tubes are produced by electric resistance welding operations; however, any type of standard welding operations can be applied to it. These pipes and tubes are processed from flat ASTM A671 sheets. First, these are cold formed into a cylindrical shape and then welded from its longitudinal ends.
A 671 Welded Pipe & Tubes are designed for lower to higher corrosion resistance rates in a wide range of fluctuating temperatures. It has great alloying chemistry that enables optimum corrosion resistance property. However, these pipes and tubes offer great resistance to pitting and crevice corrosion cracking. These pipes and tubes are intended to use in chemical containing environments such as chlorides, harsh acids, and other severe chemical compounds.

ASTM A671 has great resistance to organic elements. Ideally, it can serve good service in lower temperatures. It has alloying elements such as manganese, silicon, moderate carbon content. This make stabilized microstructure of alloy and provide excellent properties. A 671 has good cold work hardening rate makes it machinable ideally with standard machines and operations. It requires standard speeds and cut depths for machining. ASTM A671 Welded Pipe & Tubes are used in piping systems that works at high pressure. Therefore, the products are designed to withstand such a critical pressure without any damage.
