Domestic implementation SY/ t0413-2002 standards, in 2002 August 1 implementation.Main specification standard polyethylene and 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.The impact strength of 3PE anticorrosive coating is greatly improved.SY/ t0413-2002 greatly improved the stripping strength and impact resistance index of 3PE anticorrosive coating, and specified the carbon black content of some special materials, which ensured the mechanical strength and weatherability of 3PE anticorrosive coating, and increased the sampling frequency of the stripping strength (i.e. the stripping strength of primer steel with heat-shrinkable sleeve and heat-shrinkable belt) of the filler.

In the early 1980s, 3PE anticorrosive steel pipe was first widely used in Europe and was well received by users. It is the most widely used pipeline coating system.In the summer of 1994, CNPC decided to introduce 3PE coating and coating technology for the shan shan oil pipeline and shan shan oil pipeline to be developed.In December of the same year, experts from petrochina infrastructure bureau, pipeline bureau, sichuan petroleum design institute and northwest pipeline command jointly organized a delegation to the United States, Italy, Turkey and other countries to inspect the 3PE coating line.In May 1995, liaohe oil construction co., LTD., in charge of bidding, introduced the first 3PE coating line in China from Canada genlaw.Normal production began in early 1996.In 1996, the shuozhou sterine plant, jointly built by Italy soxum and Harbin plastics plant no.6, was transformed and put into normal production in May.The 3PE coating line, introduced from the Netherlands by the northwest pipeline headquarters and Hong Kong joint venture, was built and put into operation in baoji yadong anticorrosion company in 1996. So far, 3PE anticorrosion has gained attention and application in China.From the beginning of the construction of the shibuninglan pipeline, through the bidding, coupled with all the domestic production of 3PE anticorrosive materials, the precast price of 3PE anticorrosive has been greatly reduced. Since then, the era of 3PE anticorrosive has been widely used in China. So far, the external anticorrosive coating of buried steel pipe with a length of 20000KM has been applied with 3PE anticorrosive coating.At present domestic dozens of 3 PE coating production line, has the processing Φ 25-2800 - mm steel pipe of 3 PE coating capability.

For the use of 3PE anticorrosive steel pipe many people only know one do not know the other, its role is really a very wide coverage, it is suitable for underground coal mine drainage, shotcrete, positive and negative pressure ventilation, drainage gas, fire sprinkler pipe network.Thermal power plant process water waste residue, return water pipeline.It has excellent applicability for water supply pipeline of anti-spray and sprinkler system.Power, communication, highway and other cable protection sleeve.Suitable for high-rise building water supply, heat supply network, tap water engineering, gas transmission, buried water and other pipelines.Petroleum transportation pipeline, chemical industry, pharmacy, printing and dyeing and other industries conveying corrosive medium process pipeline.Sewage treatment discharge pipe, sewage pipe and biological pool anti-corrosion engineering.It can be said that 3PE anticorrosive steel pipe is indispensable in the current construction, and it is believed that with the extension of science and technology, it will have more brilliant achievements in the future.
