3PE anticorrosion spiral steel pipe manufacturer /3PE anticorrosion pipe manufacturers - Hebei Tianze pipeline limited company welcome to visit factory.
3PE anticorrosion pipe has been 3PE for the service life of the anti-corrosion concern, more and more people for the problems appeared in the production of 3PE, anti-corrosion steel pipe has a complete set of production technology abroad, the service life is to get people's attention, the three layer structure of polyethylene coating (3PE) properties synthesis of fusion bonded epoxy powder coating and extrusion two polyethylene anticorrosive coating, interfacial properties of fusion bonded epoxy powder coating and chemical resistance properties, and polyethylene coating extrusion mechanical protection characteristics together, thus improve their performance. Therefore, the outer protective layer of the buried pipeline is very superior. 3PE corrosion is generally composed of 3 layers of structure:
First layer epoxy powder (FBE>100um)
Second layer adhesive (AD) 170 ~ 250um
Third layers of polyethylene (PE) 2.5 ~ 3.7mm in the actual operation of the three kinds of materials mixed together, through processing and steel tube firmly combined with the formation of excellent anti-corrosion layer. The processing methods are generally divided winding and die coated type two.
3PE anticorrosion pipe (three layer polyethylene) technology is an advanced anti-corrosion technology in late 90s from abroad, it is called fusion bonded epoxy / extruded polyethylene protective layer structure. 3PE anticorrosion technology has good comprehensive performance of epoxy coating and extrusion two polyethylene anticorrosion layer, the interfacial properties of epoxy coating and chemical resistance properties and mechanical properties of graphene polymer extrusion has the advantages of protecting coating etc. together, thus improve their performance. Its characteristics: high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, can be applied in 150 degree medium, in the cold zone are adapted to. Therefore, the 3PE anticorrosion layer is an ideal protection layer for buried pipeline. According to the authoritative department testing, with 3PE corrosion protection technology for the buried pipeline life can be up to 50 years. Three tier PE has been the first in the petroleum and natural gas systems to be applied. China has built the Shaanxi Beijing gas pipeline and Korla Shanshan oil pipeline, the recent national key project west east gas pipeline nearly 4000 kilometers are adopted three layers of PE external coating. In the days of the city, Shaanxi gas into Tianjin 67 km high pressure pipeline, outer ring road 30 km high pressure natural gas pipeline, Shaanxi Beijing line underground gas storage reservoir 122 km pipeline is also the use of the three layer pe. It has become the development direction of the pipeline outside anticorrosion layer in the future.
