Bangdong provide Equal Tee information

The equal-diameter tee is used in the connection of the pipe to connect the different pipes to the pipe, which plays an important connection role. It is used and promoted in the installation of pipelines. The use of three-way fittings of different materials will have different effects and performance.

Classification of one or three links

The three-way in the pipeline is divided into three-way mechanical, three-way three-way, three-way three-way, three-way three-way, three-way three-way, three-way, three-way, three-way, three-way, three-way, three-way Butt welding tee, casting tee, etc. There are two types of tees according to the shape, equal-diameter tee and reducer tee. Equal-diameter tee is the same size as three mouths.

Second, the characteristics of the equal-diameter tee

The installation of equal-diameter tee is well-forged, the surface is smooth, acid and alkali resistant, high temperature resistance, reasonable price calculation, beautiful appearance and strong texture performance. Play an important role in the use, withstand the harsh conditions and perform well in value and role. The equal-diameter tee is acid and alkali resistant and anti-corrosive. It is suitable for small-flow liquid pipe output equipment and other fluid pipe fittings.

Third, the process of three-way three-way

The equal-diameter tee has a unique production process and technical parameters, and is produced according to a certain process to ensure good use value and function in production and use. The production process of PPR pipe fittings - equal tee is as follows:

Stainless steel tube→ blanking→bulging→punching forming→flat head→welding port (or interface)→solid solution treatment→washing white→wearing welding mark→fine light→air pressure detection→surface inspection→posting trademark and certificate→packaging Library. According to this workflow, the use and processing are carried out to ensure the quality and performance of the processed materials, and processing according to a certain process to ensure the smooth progress and use of the work.

Fourth, equal diameter tee technical parameters:

1. Execution and reference standards for production and processing: GB/T 12771-2000 "Stainless steel welded steel pipes for fluid transportation" and GB/T 12459-2005 "Steel butt welded seamless pipe fittings". According to these two standards for production and processing, to ensure that in accordance with certain standards in production, to ensure that the production of PPR pipe - equal diameter tee in line with national production standards.

2, the working temperature of the equal-diameter tee: -40 ° C ~ 200 ° C, in use in accordance with the temperature, strictly control the temperature;

3. Pulling test: the connecting and pulling force of the argon-arc welded pipe fittings is 3 times of the national standard;

4, flattening experiment: the pipe is flattened to 1/3 of the outer diameter, no cracks or cracks;

5, air pressure test: each pipe is tested by 1.6 Mpa air pressure;

6. Pressure test: After the pipe is connected with the pipe fittings, there is no leakage at the joint under 2.5 Mpa and pressure for 5 min;

7. Tensile strength: not less than 520Mpa, the elongation is not less than 35%, the measured value of this product is 733 Mpa;

8. Corrosion resistance: The welds of pipe fittings are not rusted by salt spray test.

The production process and technical parameters of the equal-diameter tee need to be carried out according to certain methods and methods to ensure that they play an important role and value in use. The technical parameters of PPR pipe fittings - equal-diameter tees need to be strictly controlled, strictly in accordance with the parameters for use and production. The production of equal-diameter tees will have high-quality performance, which will have an important role and value in production.

Fifth, the use of equal-diameter tees:

1. PPR pipe - equal-diameter tee The main building's hot and cold water system, including the central heating system, is mainly applied to the main connection of the PPR pipe and can play an important connection role;

2. Heating systems in buildings, including floors, siding and radiant heating systems, using PPR pipes for connection of pipes in different systems;

3. Pure water supply system that can be directly consumed;

4. Central (concentrated) air conditioning system;

5. Transportation or discharge of industrial piping systems such as chemical media.

Sixth, how to choose the equal diameter tee:

1. Pay attention to the determination of the overall use coefficient C (ie safety factor) of the pipeline: general occasion, and continuously make the temperature <70 °C for a long time, optional C=1.25; in important occasions, and the long-term continuous use temperature ≥70 °C, and it is possible Run at a higher temperature for a longer period of time, optionally C=1.5;

2. For cold water (≤40°C) system, use P.N1.0～1.6MPa pipe and pipe fittings; use for ≥PN2.0MPa pipe and fittings for hot water system.

3. After considering the above two principles, the SDR of the pipe fittings should not be greater than the SDR of the pipe, that is, the wall thickness of the pipe fittings should not be less than the pipe of the same specification.
