HDPE water supply pipe characteristics:

1. Long service life: under normal conditions, the short service life can reach 50 years.
2. Good sanitation: PE pipe is non-toxic, does not contain heavy metal additives, does not scale, does not breed bacteria, and solves the problem of secondary pollution of drinking water. Comply with the provisions of GB/T17219 Safety Evaluation Standard and the relevant health evaluation provisions of the Ministry of Health.
3. It can resist the corrosion of various chemical media: no electrochemical corrosion.
4. The inner wall is smooth, the friction coefficient is extremely low, the medium passing capacity is correspondingly improved and has excellent wear resistance.
5. Good flexibility, high impact strength, strong shock resistance and distortion resistance.
6. Light weight, convenient transportation and installation.
7. The unique electric melting connection, hot melting butt joint and hot melting socket connection technology make the interface strength higher than that of the pipe body, ensuring the interface strength.
8. The welding process is simple, the construction is convenient, and the comprehensive cost of the project is low.
9. PE Huankang water supply pipes dn20~dn90 are blue, those above dn110 are blue or black with blue lines, other colors need to be customized, and the color of fittings corresponds to the color of pipes.
10. Low flow resistance: HDPE water supply pipe has smooth internal surface, and its Manning coefficient is 0. 009。 The smooth performance and non adhesion characteristics ensure that the HDPE water supply pipe has the conveying capacity compared with the traditional pipes, and also reduces the pressure loss and water transmission energy consumption of the pipeline.

The color of HDPE water supply pipe shall be blue or black, and the black pipe shall be provided with co extruded blue bars. There shall be at least three color bars along the longitudinal direction of the pipe. Appearance: the color of pipes shall be basically the same. The surface of the pipe shall be smooth and flat, without cracks, bubbles, peeling, obvious impurities and serious shrinkage. Tube The end face of the material shall be cut flat and perpendicular to the axis.
