Jun. 25, 2018

Structure of internal epoxy monolayer polyethylene in epoxy coated steel pipe

1. Steel pipe substrate: seamless steel pipe, welded steel pipe (straight weld, spiral weld)

2. Inner anti-corrosion coating: sanitary grade epoxy powder coating, heavy-duty anti-fat epoxy resin powder.

3. External anti-corrosion coating: hot-melt single-layer polyethylene powder coating


Internal epoxy three-layer polyethylene (3PE) structure

1. Steel pipe substrate: seamless steel pipe, welded steel pipe (straight weld, spiral weld)

2. Inner anti-corrosion coating: sanitary grade epoxy powder coating, heavy-duty anti-fat epoxy resin powder.

3. External anti-corrosion coating: hot-melt three-layer structure of polyethylene coating, the bottom layer is a fusion epoxy powder, the middle layer is hot melt adhesive, the outer layer is high-density polyethylene.
