Nominal diameter is also called mean outside diameter. Standard diameter is represented with DN and the unit symbol is mm. For example, there is a vessel with 1200mm inner diameter, thus its nominal diameter can be marked as DN1200. In general situation, there are three kinds of objects that can be...

As a kind of pipe fittings, stainless steel tees are also called as pipe tees or tee joint pipe fittings. They are mainly applied to connect main pipes and branch pipes. There are equal tees and reducing tees. Just as the name suggests, the ends of equal tees are of the same sizes. For reducing tees,...

The threaded connection is also called as screwed connection. It is a method that connects two pipelines or a pipeline and a valve through internal and external threads. Galvanized steel pipes that used in building water supply system can only be connected with threaded means.    In general,...

Olets are also called as saddle shaped pipe joints. Pipe olets are mainly used to reinforce the connection of branch pipes. Being safe and reliable, olets usually take place of pipe tees, reinforcement plates, stiffening pipe sections and other pipe joints.    It is convenient for constructors...

A union is a kind of pipe fitting that can be easily installed and disassembled.    Unions are composed of three parts, that is, nuts, cloud heads and butt joints. The union is a kind of pipe fitting that forged with steel rods or steel ingots. According to different joint methods, unions...

A pipe tee, just like what it is called, has three mouths: one entrance, two exits or two entrances and one exit. It is a kind of pipe fittings used in the junction of three same or different pipes. There are T-shape tees, Y-shape tees, equal tees and reducing tees. The main function of pipe tees is...

In general, apart from straight pipes, all accessories applied to a pipeline system are collectively known as pipe fittings. Nevertheless, we often refer to elbows, tees, reducers, caps and other varied joints as pipe fittings. At the same time, products like flanges, valves, expansion joints, piping...

1. Materials of stainless steel pipe fittings can not contact with others directly. Non-metallic materials should be added such as wood or rubber panels.   2. Arc starting should apply bake welding method and arc ending should fill the arc crater. Arc ending must be completed within a groove. Arcing...

A stainless steel pipe reducer (with a larger and a smaller head) is applied to pipeline where size diameter needs changing. Forming process methods used for reducers commonly contains necking pressing, expanding pressing or a combine of these methods. For some reducers with certain specifications,...
