China Dual Phase Steel Flange Manufacturer, Supplier, Factory

SN Valve is a leading China figure-8 blank manufacturer. The Figure-8 Blank is a specially shaped piping accessory that resembles the cross-section of the number ‘8’. It is mainly used in piping systems, especially in the need to isolate or cut off the pipeline medium occasions. Through the installation of 8-word blind plate, you can achieve effective isolation of the pipeline, so as to facilitate the overhaul, maintenance or replacement of other accessories in the pipeline.

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.

Socket Welding Tee (Socket Welding Tee) is a kind of important pipe fittings with wide application in piping system. Its unique advantages and values are reflected in its structural characteristics, manufacturing process and materials, specifications and pressure levels, as well as application areas. In the process of welding and use, it is necessary to strictly comply with the relevant norms and precautions to ensure its safe and reliable operation.

Flat Face Flange is a type of flange in which the sealing surface and the overall end face of the flange are in the same plane. Its design feature is that the sealing contact surface is flat, without protrusions or depressions, suitable for sealing scenarios that require large areas of uniform contact.

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.

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.
