China LWN Flange Manufacturer, Supplier, Factory

SN Valve is a leading China lap joint stub ends manufacturer. Lap Joint Stub Ends are short pipe joints with a flanged construction, designed to be butt-welded to the pipe at one end and designed to be used with loose flanges as the connecting surface at the other end. This design allows Lap Joint Stub Ends to make flexible and reliable connections in pipework.

High quality high pressure butt welding flange is offered by China manufacturer SN Valve. High-pressure butt-welding flanges are the type of flanges that are butt-welded to the pipeline through the long neck, and their structural features include the long neck, the flange face and the welding bevel. The design of the long neck part makes the connection between the flange and the pipe stronger and can withstand higher pressure and temperature. The flange face is used to make contact with the sealing gasket to form an effective seal. The design of the welding groove is to facilitate the welding of the flange and the pipeline.

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.

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.

SN Valve is a leading China stainless steel 90° industry elbow manufacturer.

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.
