Key points of construction and installation of coated steel pipe
1). It shall be implemented by "Technical Regulations for Construction Water Supply Plastic Coated Composite Pipeline Engineering" CECS125:2001.
2) The following construction equipment should be used for coated steel pipes:
(1) Cutting should be done with a metal saw;
(2) The pressing groove should adopt a special groove rolling machine;
(3) The pipe bending machine should be cold bending;
(4) The pipe threading machine should be used for pipe thread processing;
(5) Deburring and processing corners of plastic-coated steel pipe ports should be processed with files;
(6) Small brushes or small toothbrushes should be used to apply high-strength inorganic solvent liquid epoxy resin coatings.
