Pressure Vessel Flange

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.

Long Weld Neck Flange

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.

Butt Welding 180 Degrees LR Return

SN Valve is a leading China butt welding 180 degrees lr return manufacturer. Butt welding 180 degrees lr return elbows are connected to the pipeline by welding and have a 180-degree bending angle and a long bending radius, hence the name long radius (LR) return elbow. The design of this elbow allows for smoother fluid flow through the pipeline, reducing flow resistance and pressure loss, while providing more space to accommodate piping layout and installation.

Socket Welding Coupling

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.
