China LWN Flange Manufacturer, Supplier, Factory

SN Valve is a leading China butt welding 45 degrees short elbow manufacturer. Butt welding 45 degrees short elbow is a pipeline connector manufactured through hot pressing, cold working, welding and other processes, with an angle of 45 degrees, the connection is butt-welding, i.e., the elbow is directly welded to the pipe.

SN Valve is a leading China stainless steel 180° industry elbow manufacturer.

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.

Pressure vessel flange, i.e. pressure vessel flange, is a key component on the pressure vessel used to connect piping, valves, instruments and other equipment.Pressure vessel flange is a standardized connecting part, which is connected to the inlet and outlet of the pressure vessel or other parts that need to be connected to achieve a reliable connection between the pressure vessel and other equipment or pipelines. In the pressure vessel, the flange not only plays the role of connection, but also bears the important task of ensuring the sealing performance and bearing pressure.

The rubber flexible joint flange is a part used to connect pipes and equipment together. It consists of two parts: a flexible rubber joint and a flange. Rubber flexible joints are usually made of rubber materials and have good elasticity and sealing properties. In addition, they can also absorb the vibration and displacement of the pipeline to protect the pipeline from damage. On the other hand, a flange is a metal part used to connect pipes or equipment, with one or more protruding edges (i.e., flange faces) for bolting with other flanges or parts.

SN Valve is a leading China copper alloy tube sheet manufacturer. The production process of copper alloy tube and plate usually includes raw material preparation, melting and casting, processing and moulding, heat treatment and surface treatment and other steps. Among them, melting and casting is the copper alloy raw materials into liquid state after melting and casting into the required shape; processing and forming through cutting, drilling, welding and other processes will be processed into the casting of the pipe plate in line with the requirements of the heat treatment can further improve the mechanical properties of copper alloys and corrosion resistance; surface treatment can improve the surface quality of the pipe plate and corrosion resistance.
