China FF Flange Manufacturer, Supplier, Factory

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.

SN Valve is a leading China carbon steel tube sheet manufacturer. Carbon steel tube plate is mainly used in shell-and-tube heat exchangers, boilers, pressure vessels, steam turbines, large central air-conditioning and other equipment, play a role in supporting and fixing the tubes and shells, thermal conductivity, corrosion resistance, as well as withstand high pressure.

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.

Threaded flanges are flanges with internal or external threads that are connected by screwing the threads on the flange to the threads on the pipe or equipment against each other. This type of flange is usually used in low-pressure and low-temperature operating environments because of its relatively low connection strength, but easy installation and removal.

SN Valve is a leading China threaded cross manufacturer. Threaded tee is an important pipe fitting that connects four pipes together by means of a threaded connection to realise the diversion or merging of fluids. 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 systems for changing piping direction, branching piping or realising special connections.

Bellows Flange is mainly used to connect bellows with other components such as pipes, equipment or valves. It connects the bellows with the flange through bolts or other fastening devices to form a reliable connection system. Bellows flange plays the role of connection, support and sealing in the piping system, and can withstand certain pressure and displacement.
