Petroleum asphalt, raw materials wide, low prices. However, poor working conditions, difficult to guarantee quality, serious environmental pollution.


Coal tar epoxy, easy to operate, but a long time covering layer is cured by environmental impact, suitable for field work, the following 10 ℃ difficult construction.


Anticorrosive cold tapes, easy to operate, but slightly worse adhesion, low water resistance, low intensity, the large environmental impact.


Epoxy powder corrosion, electrostatic spraying, anti-corrosion material with the same kind of tube frit good, strong bonding, epoxy powder but water is poor (high water absorption, reaching 0.83%), to cathodic protection design bring some difficulties. Site appliance requirements, the operation is difficult, difficult to control quality.


3PE shrink materials, sealing strong pipeline corrosion, high mechanical strength, water resistance strong, stable quality, convenient construction, applicability, and do not pollute the environment. PE low water absorption (less than 0.01%), along with high strength epoxy, hot melt adhesive PE low water absorption and good flexibility, high corrosion reliability, the disadvantage is: Compared with other mending material costs high cost.


Features cold tapes and 3PE shrink bands are: for all kinds of pipe coating material of the body, while the other method is applicable to the same or close to the pipe coating material body.
