China LWN Flange Manufacturer, Supplier, Factory

SN Valve is a leading China carbon steel tube sheet manufacturer. Carbon steel tube plate is mainly used in shell-and-tube heat exchangers, boilers, pressure vessels, steam turbines, large central air-conditioning and other equipment, play a role in supporting and fixing the tubes and shells, thermal conductivity, corrosion resistance, as well as withstand high pressure.

Long Weld Neck Flange (LWN) is an extended form of butt welded flange with a neck, whose neck height is significantly higher than that of ordinary butt welded flanges. The neck is usually designed in a straight cylindrical shape, and the height is adjusted according to the nominal diameter (DN): when DN ≤ 100, the neck height is 229mm, and when DN>100, it is 305mm. The thickness of the neck wall gradually transitions to the thickness of the pipe wall, effectively improving the stress distribution, enhancing the rigidity and bearing capacity of the flange, making it suitable for working conditions with high pressure, high temperature and frequent temperature changes.

Shuangneng is a professional manufacturer and supplier of Industrial Grade Boom Manway in China, which is a mechanical device designed for heavy industries, construction sites and other occasions where heavy objects need to be moved vertically. Our customizable product can be powered by a hydraulic system that can accurately lift or lower heavy loads to meet a variety of height and weight requirements. These lifting platforms are usually equipped with a stable frame structure and flexible operating devices to ensure their efficient and stable operation in complex environments.

SN Valve is a leading China socket welding coupling manufacturer. Socket weld pipe hoop is a kind of pipe fitting that connects two pipes together by socket welding. Its structure is characterised by the design of a socket at one end, which can be inserted into the end of another pipe and welded to make the two close together. Socket welded pipe hoop is usually machined from round steel or ingot after die forging, with key dimensions such as socket hole diameter, socket hole wall thickness and socket hole depth.

SN Valve is a leading China socket welding 90 degrees elbow manufacturer. Socket welding 90 degrees elbow plays a role in pipeline connection to change the direction of fluid transmission, so that the fluid can be turned at right angles. It is designed with a socket at one end, and the other end is matched with the outside diameter of the pipeline, for insertion into the main pipe for welding. Socket welding 90 degree elbow is mainly used in small diameter, high pressure piping system, especially in the need to strictly control the risk of leakage and higher strength requirements of the occasion, such as petroleum, chemical, electric power and other industries in the pressure piping system.

Find a huge selection of Plate (PL) Flanges from China at SN Valve. Plate flat welding flange is a kind of flange cut from steel plate with a full flat flange face and a round bore in the center for connection with pipes or other flanges. The connection is usually made by flat welding, i.e., the flange is aligned with the protruding part of the pipe or equipment and then firmly connected by welding.
