Needle Valves

Hitesh Metal is expertise trader & supplier for high quality Steel Needle Valves , which is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. Fatigue resistance is lower than that in butt - welded construction due to the use of fillet welds and abrupt fitting geometry, but it is still better than that of most mechanical joining methods. Stainless Steel Needle Valves offered by Hitesh Metal are used for lines conveying flammable, toxic or expensive material where no leakage can be permitted. Valves are used only in conjunction with ASME Pipe and are available in the same size range. Carbon Steel Needle Valves are used in areas where pipe - work is permanent and are designed to provide good flow characteristics. They are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller. Alloy Steel Needle Valves offered by Hitesh Metal is a good choice wherever the benefits of high leakage integrity and great structural strength are important design considerations. To join pipe to Valves and fittings or to other sections of pipe, fillet - type seal welds be used. Duplex Steel Needle Valves are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. Hitesh Metal also offer these Nickel Alloy Needle Valves in different sizes, shapes and designs as per customers specifications at affordable rates.
