The line pipe transports the oil, gas or water extracted from the ground to the petroleum and natural gas industrial enterprises through the line pipe. Line pipes include seamless pipes and welded pipes. The pipe ends have flat ends, threaded ends and socket ends; the connection methods are end welding, coupling connection, socket connection, etc. Line pipes are used for gas, water and oil transportation in the petroleum and natural gas industries. API SPEC 5L-2011 (line pipe specification), compiled and issued by the American Petroleum Institute, is commonly used all over the world.The line pipe supplier will explain to you what are the advantages of line pipe? 

Advantages of line pipe

1.Hygienic and non-toxic

The material is completely composed of carbon and hydrogen without any toxic heavy metal salt stabilizer. The hygienic performance of the material has been tested by the national authority.

2. Light weight

The density of stamping elbow is 0.89-0.91g/cm, which is only one tenth of steel pipe. Due to its light weight, it can greatly reduce the transportation cost and the construction intensity of installation.

3. Good heat resistance

when the working water temperature is 70 degrees, the softening temperature is 140 degrees.

4. Good corrosion resistance

Except for a few hydrogenating agents, it can withstand the erosion of a variety of chemical media. It has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no bacteria, no electricity Chemical corrosion.

5. Good thermal insulation

Due to the low thermal conductivity of the material, the thermal conductivity at 20 degrees Celsius is 0.21-0.24W/mk, which is much smaller than steel pipe (43-52W/mk) and purple steel pipe (333W/mk), so PP-R The tube has good heat preservation.

6. High impact resistance

Due to its unique impact strength performance, it is significantly improved compared to other solid-wall pipes, and its ring stiffness is equivalent to 1.3 times that of the solid-wall pipe.

7. Long service life

The pipe has a service life of more than 50 years under the rated temperature and pressure. It has anti-ultraviolet and anti-radiation, so that the product will never fade
