What are the characteristics of 3PE anticorrosive steel tubes
1, the polyethylene material made of 3PE control, so that the pipe life is long, molecular weight is large, good stability, aging resistance, under the normal working temperature and pressure, can guarantee the service life of more than 50 years.

2. 3PE steel tube has high corrosion resistance of polyethylene and chemical corrosion resistance of natural gas, liquefied gas and man-made gas. The chemicals in the soil do not degrade in the pipe.

3. The elongation at break of 3PE steel pipe is above 500 percent. Polyethylene has good elasticity and is easy to bend.

4, polyethylene has good impact resistance, seismic performance, and has a high temperature adaptability, can be used in the temperature range of 60~80℃ can rest assured, the non-uniform settlement of the pipe foundation is also very strong adaptability, therefore, in winter construction, due to the good impact resistance of the material, will not occur embrittlement phenomenon.

5. No heavy metal stabilizer is added when 3PE steel pipe is processed with polyethylene material, which is non-toxic and harmless. This is a green pipe. Polyethylene materials can be recycled, will not cause pollution to the environment.

6. The new type of flame retardant and antistatic 3PE steel pipe is suitable for inflammable and explosive places.

7. The reliable connection mode of 3PE polyethylene steel tube and pipe is mainly hot-melt or electro-melt. The interface material, structure and pipe body are basically consistent, realizing the combination of joint and pipe material, effectively resisting annular stress, axial tension and oblique stress are caused by internal pressure, and there is no need to worry about leakage and air leakage.

3PE polyethylene steel pipe is light in material, simple in operation, simple in construction, only 1/8 of the steel pipe, simple in welding process, fast, easy to operate, easy to bend, low comprehensive cost, significant economic benefits.
