China LWN Flange Manufacturer, Supplier, Factory

SN Valve is a leading China threaded 45 degrees elbow manufacturer. Threaded 45 degrees elbow bends the pipe in 45-degree direction by means of threaded connection, so as to realise the change of pipe direction. It is widely used in industrial fields such as petroleum, chemical, natural gas, water treatment and heating, as well as in building and civil piping system.

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

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.

Find a huge selection of stainless steel tube sheet from China at SN Valve. Stainless Steel Tube Sheet is a structural material made of stainless steel in the form of a combination of tubes and sheets. It is an alloy with excellent corrosion resistance. It has a chromium content of at least 10.5 per cent and a carbon content of no more than 1.2 per cent, with possible additions of nickel, molybdenum, titanium and other elements to enhance performance.
Corrosion resistance: It is resistant to weak corrosive media such as air, steam and water as well as chemical media such as acids, alkalis and salts.
High strength: stainless steel has high tensile and yield strength, which can meet the needs of various structural applications.
Excellent processing performance: easy to cut, bend, weld and other processing operations, easy to make a variety of shapes and sizes of pipe and plate structure.

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.

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.
