PE USED FOR WATER SUPPLY AND WASTEWATER

POLYETHYLENE (PE) PIPES AND FITTINGS FOR WATER SUPPLY AND SEWERAGE SYSTEMSPOLYETHYLENE (PE) PIPES GAMRATGAMRAT PE pipes are manufactured by extrusion of polyethylene of a density higher than 930 kg/m3 with the addition of antioxidants, stabilizers and pigments necessary for the production of pipes of specifi c mechanical properties and weldability. The base resin is HDPE of PE100 grade. The quality of polyethylene is confirmed by suppliers’ certifi cates. High quality raw materials and our production technology on a global level, and the ability to make inspection and analytical testing enable us to manufacture pipes of the highest quality, in accordance with the requirements of international standards. 

GAMRAT POLYETHYLENE PIPES PE ARE DESIGNED FOR THE DISTRIBUTION OF DRINKING WATER, TECHNOLOGICAL LIQUIDS, AND SEWAGE AS WELL AS PROTECTIVE PIPES. THIS VARIETY OF APPLICATIONS OF POLYETHYLENE PIPES RESULTS FROM THEIR EXCELLENT PHYSICAL AND MECHANICAL PROPERTIES AND THEIR RESISTANCE TO AGGRESSIVE MEDIA. AT THE SAME TIME, POLYETHYLENE PIPES ARE PHYSIOLOGICALLY NEUTRAL AND HARMLESS TO THE ENVIRONMENT.

Advantages of PE pipesGAMRAT Polyethylene pipes, along with the entire range of fi ttings for permanent and detachable joints, create a uniform and universal system that ensures more than 50 years of service life. The system is characterized by:

• excellent mechanical strength;
• high impact resistance (the PE pipes do not crack under impact, even at low temperatures down to – 80°C);
• very good fl exibility;
• possibility of capping pipes and stopping the media flow for renovations;
• smooth internal surface that reduces the flow resistance;
• low weight;
• pipe joints made easily and quickly;
• resistance to corrosive agents in the soil;
• resistance to stray electrical currents;
• physiologically inertness – plastic material do not release any contaminants to the environment

Physical and mechanical properties

• Density of pipe material: 0,930–0,960 g / cm3
• Melt fl ow index: 0,2–1,4 g/10 min. at the load of 5 kg and temperature of 190°C
• Ultimate elongation at rupture: not less than350%
• Thermal stability, at. 200°C: not less than 20 min
• Linear thermal expansion: 0,2 mm / m / °C
• Elasticity coefficient: 600–800 N / mm2

The GAMRAT polythene pipes for water supply and sewage transportation are made of:

• PE 80 class material for pressures of 0,5; 0,63; 0,8; 1,0 and 1,25 MPa ( PN 5; PN 6,3; PN 8; PN 10 and PN 12,5)
• PE 100 class material for pressures of 0,6; 1,0 and 1,6 MPa (PN 6; PN 10 and PN 16).

The pipes are manufactured in blue or black. In case of black pipes it is possible to make four or six colour stripes.

PE PRESSURE FITTINGS FOR WATER SUPPLY AND SEWERAGESegmented fi ttings are produced in stationary conditions by butt welding of PE100 polyethylene pipe segments and PE100RC polyethylene pipe segments.  They are used for construction and repair of water supply and sewage systems. The offer includes SDR 11 and SDR 17 fi ttings of the following types:

• bends with angles 15°, 30°, 45°, 60°, 75°, 90° with diameters ranging from 90-500 mm
• equal tees of the inlet angle of 90° with diameters ranging from 90-400 mm
• reducing tees of the inlet angle of 90 ° with diameters ranging from 90-160 mm
• reduction couplings available with diameters ranging from 90-160 mm
