Loose Flange

Loose flange is a type of flange connection that is characterized by a certain degree of mobility or removability of the connection between the flange and the pipe or equipment. This type of connection allows the flange to be easily Loose flange is widely used in a variety of industrial fields, especially in situations that require frequent disassembly and replacement of equipment. It allows the pipeline or equipment to be moved and adjusted to a certain extent without being restricted by the flange, thus improving the flexibility and adaptability of the system.

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.

High Pressure Butt Welding Flange

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.

Socket Welding Cross

A socket welding cross is a fitting with four openings, three of which are connected to the main pipe and one of which serves as a connection for a branch pipe. Its structure is characterised by the fact that at least one of the openings is designed as a socket port, which can be inserted into the pipe and connected by welding. Socket weld cross is usually made of high quality carbon steel, alloy steel or stainless steel to ensure its high strength and good sealing performance.
