JIS/KS Carbon Steel Equal Tee
JIS/KS Carbon Steel Equal Tee
JIS/KS Carbon Steel Equal Tee is one of pipe fittings standard. Steel equal tee is the same size of the three end.It usually using in the pipeline trigeminal mouth. This month our finish the carbon steel equlal tee for spain customers .Equal tee is used in the connection of pipelines, connecting different pipes and connecting between pipes, playing an important role in connecting. Standardized use and promotion in the installation of pipelines, the use of three-way pipe fittings with different materials will have different effects and performance.
Equal teepass technical parameters:
1. Implementation and Reference Standards for Production and Processing: GB/T 12771-2000 “Welded Steel Pipes for Fluid Transportation” and GB/T 12459-2005 “Seamless Steel Butt Welded Pipes”. In accordance with these two standards for production and processing, to ensure that the use of certain standards in accordance with the production of PPR fittings – equal diameter tee in line with national production standards.
2. The working temperature of the equal tee is – 40 ~200 ~C. It is used according to the temperature in use, and the temperature is strictly controlled.
3. Drawing test: the drawing force of socket welded argon arc welded pipe is 3 times of the national standard.
4, flattening experiment: flattening the tube to the outer diameter of 1/3, there will be no cracks or cracks.
5. Air pressure test: each pipe is subjected to 1.6 Mpa air pressure test.
6. Pressure test: After connecting the pipe with the fittings, there is no leakage at the joint under the condition of 2.5 Mpa and holding pressure for 5 minutes.
7, tensile strength: not less than 520Mpa, elongation of not less than 35%, the measured value of this product is 733 Mpa;
8.Corrosion resistance: pipe fittings are not corroded by salt spray test.
The production process and technical parameters of equal tees need to be carried out in a certain way and method to ensure that they play an important role and value in use. The technical parameters of PPR pipe fittings and equal diameter tees need to be strictly controlled. If they are used and manufactured strictly according to the parameters, the equal diameter tees will have high quality performance and play an important role and value in production.
Five, the use of equal diameter three links:
1. The cold and hot water system of the main building, including the central heating system, is mainly suitable for the main connection of the PPR pipe, and can play an important role in connecting.
2. The heating system in the building, including floor, panel and radiant heating system, uses PPR pipe to connect pipes in different systems.
3, can be directly drinking pure water supply system;
4, central (centralized) air conditioning system;
5, transportation or discharge of chemical media and other industrial piping systems.
Six, how to choose equal diameter three links:
1. Attention should be paid to the determination of the overall utilization coefficient C (i.e. safety factor): in general occasions, and long-term continuous temperature less than 70, can choose C = 1.25; in important occasions, and long-term continuous use of temperature more than 70, and may be longer in higher temperature operation, can choose C = 1.5;
2. For cold water (<40) system, P.N1.0-1.6 MPa pipe and fittings are selected; for hot water system, P.N 2.0 MPa pipe and fittings are selected.
3. After considering the above two principles, the SDR of the fittings should not be greater than that of the pipes, that is, the wall thickness of the fittings should not be less than that of the pipes of the same specification.
