Structure of the Anticorrosion Coating
The coal tar epoxy coating anti-corrosion steel pipe exploits the two-component room temperature curable coating and uses the glass fiber fabric on the surface of the steel tube as strengthening coating. The coal tar epoxy anticorrosion coating is classified into the common level, strengthening level (one layer of glass fiber fabric and three layers of the anticorrosion coating) and the special strengthening level (two layers of glass fiber fabric and four layers of anticorrosion coating).
