Welded stainless steel pipe fittings
The stainless steel pipe fittings are the pipe fittings that connected by inserting the stainless steel tubes into the pipe fittings and then doing the argon arc welding on the edge of the pipe pieces, which is the most reliable way of connecting all the connections. Inner diameter of pipe fittings is equal to pipe diameter. According to the welding parts of the pipe fittings, the welding parts can be divided into three kinds of pipe fittings: slope extension, edge extension and no extension, and the welding specifications are usually dn15-dn100.

Butt welded stainless steel pipe fittings
Butt welded stainless steel pipe fittings are the pipe fittings of the stainless steel tubes and pipe fittings to the seam of argon arc welding. Welding is usually required. Outer diameter of pipe fittings is equal to pipe diameter. Butt welding is generally used for welding of stainless steel piping systems with larger specifications.

Press-fitting stainless pipe fittings
They have the characteristics of reliable safety, convenient construction, convenient installation, maintenance and update, and relatively superior economy.
The working principle of press-fitting pipe fittings are as follows: insert the thin-walled stainless steel tubes  into the press-fitting pipe sockets, clamp the stainless steel pipe fittings inside with special tools.Their cross sections are hexagonal, besides,there are o-rings seals between the stainless steel pipes and pipe fittings , and they have the characteristics of stop seepage, tensile, shock resistance and high pressure resistant. Thus, it is a relatively advanced connector in the direct drinking water system, the water system, the heating system, the steam system, the industrial tubing system and the industrial tracheal system.They are applicable to water, oil, gas and other pipe connections.

Rapid  connecting  pipe fittings
Push fit - self  Lock pipe fittings
Rapid connecting method is a kind of "Push Fit - Self  Lock" technology, as long as the tube is  inserted into push fit - self  lock pipe fittings, it will rapid connect them, and when disassembling, you can easily remove the pipe out with the special tools.
Push fit - self  Lock pipe fittings are not only more convenient to install and remove, and they have the excellent properties of repeatable use, no leakage, shockproof, cushioning expansion and contraction.
The technology is a new exploration on the pipe connection way and breakthrough. It has been widely used and verified in the water supply system at home and abroad. The pipe fittings in Hong Kong are designated by  water supplies departments.
