High density polyethylene pipes for drinking water networks
POLYETHYLENE CHARACTERISTICS
By comparison to metal pipes, using polyethylene pipes for drinking water networks has the following advantages:
- Resistance to solvents, acids and alkaline substances;
- Good resistance to abrasive wear;
- Reduced pressure losses;
- Easy and user-friendly installation technology;
- Good bending strength;
- Minimum deposits in time;
- Reduced rugosity;
- Ecological, recyclable and non-toxic;
- Maintaining the raw material characteristics in time (polyethylene);
- guaranteed life-time of at least 50 year;
- inertia to corrosion;
- light weight and suppleness allow easy installation;
- easy weldability even at low temperatures;
- reduced installation costs;
- cheap maintenance, special reliability of connection systems;
- reducing pressure losses on the installation, constant pressure in the network;
- shock and external mechanical action resistance.
- continuous control of computer-programmed technological parameters and wall thickness by ultrasonic apparatus;
- compliance with and implementation of the requirements of quality standards, the system being certified by CERTIND S.A. - Bucharest according to the ISO 9001 - 2008 referential;
- the tests carried out in the own laboratory, accredited by the "Accreditation Association of Romania" (RENAR) through the Accreditation Certificate no. LI 033;
- approval by the Ministry of Regional Development and Public Administration for use in the transportation and distribution of drinking water;
- health certificate issued by the Ministry of Health.
