The scope of application of coating steel pipe for them to bring a lot of room for development, followed by increased demand for coating steel pipe, the manufacturers have mushroomed to build a new era of coating steel pipe with people continue to strengthen the awareness of environmental protection, Plastic pipe industry ushered in a new high-speed development stage, coating steel pipe as environmental protection, energy saving, corrosion, flame retardant quality products.
Fire coating pipe recommended welding steel pipe in the plastic pipe at the interface to be reserved 150mm long light pipe (mainly to prevent the process of erosion can be coated with high temperature anti-rust primer), so when welding will not burn Coated film. After the completion of welding, the quality of qualified to use plastic bags around the entanglement coating method, shrink tape coating method or flame spraying method on the welding and the reserved 300mm pipe end for anti-corrosion treatment.
