Product Details



Three layer polyethylene anticorrosion is one of the main technical system of buried pipeline corrosion protection at home and abroad. It has good corrosion resistance, low water absorption and high mechanical strength. It has been used more and more widely in the field of buried water conveyance, gas transmission and pipeline transportation in recent years.

standards


At the initial stage of introducing 3PE coating technology, the research institute of engineering and technology of CPC prepared the first 3PE coating construction acceptance code in China in April 1995 with reference to din30670-1991 and nfa49-710 (March 1988 edition) for construction of shan-jing pipeline and ku-shan pipeline.In the same year, it was upgraded to the industry standard SY/ t4013-1995. After several years of summary and practice of engineering construction, it was revised to SY/ t0413-2002 in 2001, and was implemented on August 1, 2002.



At the beginning of the standards, according to the actual situation of China, polyethylene is given priority to with high density polyethylene, vicat softening point was not less than 110 ℃;The thickness of the outer coating is determined according to the German standard din30670-1991, which is mainly low and medium density polyethylene.Greatly improve the impact strength of 3 PE coating, ensures the shanxi-beijing pipeline and ku-shan pipeline construction quality, SY/T0413-2002 and 3 PE anticorrosive layer of the peel strength, impact resistant index increase, according to some special material and specified by carbon black content, ensure the 3 PE coating and weather resistance, mechanical strength and increased the repairing peel strength (i.e., heat shrinkable sleeve, heat shrinkable belt of peel strength) of primer for steel of parking frequency, in order to ensure the pipe external anticorrosive coating quality has made a contribution.


Reliable research


In view of the debate on the adoption of 3PE coating in China, CNPC research institute of engineering technology, entrusted by Beijing huayu natural gas co., LTD., completed the "study on the safety evaluation of polyethylene coating on the exterior anti-corrosion three-layer structure system of shan-jing gas transmission pipeline".This study includes the analysis of the results of the excavation inspection and no-excavation inspection of the outer anti-corrosion layer of pipeline from foreign literatures collected to Beijing hualiu natural gas co., ltd. from 2001 to 2003, as well as the 3PE anti-corrosion performance inspection of the unfinished open-pit pipeline stacked in the north China petroleum steel pipe plant for 2 years and 6 years.
