the test tube respectively in three with manual winding polyethylene tape coating engineering test similar working environment: quentin ridge inside the tunnel, the outdoor ( Simulated conditions of bridge tube) , buried ( Ningbo large industrial water pipeline) 。 In about 2 months at a time for testing cycle, the mechanical winding polyethylene anticorrosive tape coating surface quality and peel strength and electric spark leak detection, tracking, monitoring result list as follows:

1, the mechanical winding of the polyethylene tape coating, although the improper protection, construction and transportation have pierced a small amount of sand surface and welding slag, to a certain extent affect the characteristics of the coating, but in the whole test engineering, anticorrosive coating still shows the stable, up to 40 n/CM of peel strength, far beyond SY/T0414 - Polyethylene anticorrosive tape 98 'steel pipeline anticorrosion coating technology standard' 18 n/CM, polyethylene tape test results show that the combination of pipeline coating strength is reliable, the mechanical winding of anticorrosive coating performance is more superior.

2, mechanical winding polyethylene tape pipeline anticorrosive coating engineering monitoring showed that coating surface, no mechanical damage during the entire test, under 8 kv voltage always maintain good insulation performance, not dozen spark, reflects its consistent resistance; And coating the surface of sand, slag burst point, deeply by early appear a few sparks, late to spark has a tendency to expand to prove: elaborate the importance of the protection coating surface intact, any tiny surface damage, the breakthrough could lead to coating, extension, so that the loss of corrosion protection.
