There are many kinds of base materials for anti-corrosion steel pipes, such as spiral steel pipes (ssaw), straight seam steel pipes, seamless steel pipes, etc. Therefore, the quality of anti-corrosion steel pipes must be judged from the base material and anti-corrosion quality.
1. Anticorrosion
(1) The appearance is delicate and the workmanship is good, without burrs.
(2) The internal plastic coating process uses electrostatic adsorption to electrostatically adsorb the epoxy resin powder on the inner and outer walls of the steel pipe, which is firm, with high hygiene level, non-toxic and non-polluting.
(3) External plastic coating process: The polyethylene coating has the characteristics of bright, good adhesion, hard appearance, wear resistance, smoothness, etc. It can withstand low temperature and prevent corrosion.
(4) No irritating odor.
2. Steel pipe
(1) There is no weld, which can be verified in a bright place.
(2) Good compressive ability and not easy to deform.
(3) Strong mechanical ability and will not break in the flaring test.
(4) There is no interference such as burrs, and the inner wall is clean and delicate.
(5) There are pipe fittings warranty and inspection report.
(6) The steel pipe is made of high-quality carbon steel without debris and has good hygiene.
