Distinguish between plastic-lined steel pipe and plastic-coated steel pipe
2023-05-12 09:55
1. Distinction in use:
Plastic-lined steel pipes are usually divided into plastic-lined steel pipes for cold water and plastic-lined steel pipes for hot water;
Plastic-coated steel pipes are usually divided into plastic-coated steel pipes for water supply and plastic-coated steel pipes for fire protection.
2. Material distinction:
Plastic-lined steel pipes are distinguished by different lining materials. They are usually divided into polyethylene PE-lined steel pipes and heat-resistant polyethylene PE-RT plastic-lined steel pipes, which are what we usually call plastic-lined steel pipes for cold water and plastic-lined steel pipes for hot water. Plastic-lined steel pipe;
Plastic-coated steel pipes are distinguished by different coating materials, usually divided into polyethylene PE plastic-coated steel pipes and epoxy resin EP plastic-coated steel pipes.
3. Process distinction:
Plastic-lined steel pipes are based on hot-dip galvanized steel pipes, and polyethylene-lined PE and heat-resistant polyethylene PE-RT plastics are used as inner linings;
Plastic-coated steel pipes are treated with polyethylene PE and epoxy resin EP plastic powder as the coating.
