Pipe Equal Tee pdf downloads

A pipe tee is defined “Equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter. Equal Tee Manufacturers in China are available in sizes from half an inch to 48 inches (or larger) and in seamless and welded execution (seamless up to 24 inches, welded for tee sizes above 24 inches).

Pipe Reducing Tee pdf downloads

Reducing Tee Fittings is another type of pipe tee used in pipe and tube fittings. Pipe Tees are available two popular forms—have all outlets of the same size or they can be reducing tees in which they are with a combination of different outlet sizes. Reducing Tee Manufacturers in China, like all pipe tees, is in the shape of T with two ends of equal size and the third one slightly smaller.

1. Large size stainless steel tee

For production of large size stainless steel tee, two steel plates are placed into corresponding mould for compression molding first by hydraulic press. Then butt welding will be done to attach these two steel pieces together. Through this exact process, the maximum caliber of the seamed stainless steel tee we could produce reaches 100 inches.

2. Seamless stainless steel tee 

In our company, there are cold press forming machines exclusive for production of seamless tee made of stainless steel. In addition, we can also produce seamless tee with larger size by hot press forming by mould process for customers.

3. Forged stainless steel tee 

Through forging process, we are also able to manufacture stainless steel socket weld tee or threaded tee.

Recommended Applications

An extensive use of stainless steel fittings can be found in the following industries:

• Petrochemical industry: Oil refining, ethylene, coal to oil, coal to olefins and other projects.
• Natural gas industry: LNG ships, LNG terminals, and natural gas pipeline projects.
• Power station industry: In thermal power plant, the water pipeline (usually stainless steel) used for supercritical units, circulating fluidized beds, power generation boilers, steam turbines, generators and other equipment, including reheater tube, superheater tube, water screen tube, economizer tube, downcomer and header, etc.
• Machinery and equipment manufacturing industry: Equipment structures such as pressure vessel, heat exchanger, fluid control, hydraulic transmission, instrumentation and others.
• Others: Shipbuilding, papermaking, desalination, food production and other industries; Aviation, aerospace, military, nuclear power plants and other projects.
