Therefore, the quality of anti-corrosion steel pipes must be judged on the base materials’ anti-corrosion quality.

1. Anti-corrosion:

(1) No irritating odor.

(2) The appearance is delicate and the workmanship is good, without burrs.

(3) 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 a high hygiene level, non-toxic and non-polluting.

(4) External plastic coating process: The polyethylene coating has the characteristics of bright, good adhesion, hard appearance, wear resistance, smoothness, etc. It can withstand low temperatures and prevent corrosion.

2. Steel pipe:

(1)Good compressive ability and not easy to deform.

(2) There are pipe fittings warranty and inspection reports.

(3) There is no weld, which can be verified in a bright place.

(4) Strong mechanical ability and will not break in the flaring test.

(5) There is no interference such as burrs, and the inner wall is clean and delicate.

(6) The steel pipe is made of high-quality carbon steel without debris and has good hygiene.
