Product Details

      Different diameter Tee (reducing tee): branch pipe and the other two diameters are called diameters three way.

It is widely used in petrochemical, petroleum and natural gas, liquefied gas, chemical fertilizer, power plant, nuclear power, shipbuilding, paper making, pharmaceutical, food hygiene, urban construction and other industries.

      The common expression methods of different diameter three-way are: large caliber size × small caliber dimension pressure grade or wall thickness.

For example: 3 "x 2" 300LB or Sch40s.

But the usual marks on the three links are wall thickness Sch40s

Different-diameter three-way, generally a professional noun, three-way pipe fittings, pipe connections, used in the main pipeline branch pipe. Different-diameter three-way is a kind of three-way, three-way general equal-diameter three-way, two different-diameter three-way. Because the three ends can be connected to the pipe and named.

Technical parameters of the three links

1. working temperature: -40 ℃ ~ 200 ℃;

2. corrosion resistance: pipe fittings weld through salt spray test no corrosion.

3.tensile strength: not less than 520 MPA, elongation not less than 35, the measured value of this product is 733 Mpa;  

4. flattening experiment: when the pipe fittings are flattened to 1 / 3 of the outer diameter, there will be no cracks or cracks;

5. execution and reference Standard: GB/T 12771-2000 stainless Steel welded Pipe for fluid conveying and GB/T 12459-2005 Steel butt welded Seamless Pipe fittings.

6. pressure test: after connection between pipe and fittings, there is no leakage in the connection under the condition of 2. 5 Mpa, pressure keeping 5min;

7. drawing test: the connecting drawing force of the inserted argon arc welding pipe fittings is 3 times that of the national standard;  

8. pressure test: each fitting was tested by 1. 6 Mpa.

      The processing method of different diameter three-way pipe fittings is to mark the different-diameter three-way pipes and break through the marks. The different diameter three-way pipe fitting processing method is suitable for the different specifications of the different diameter three-way pipe fittings on the pipeline processing; Its special processing equipment is simple in structure and low in cost. It can reduce the production cost and improve the production efficiency of this kind of pipe fittings without additional injection molding machine and injection mould.
