PE100 RC HERKULES polyethylene sewage pipes made of material with increased resistance to crack propagation and contact pressure. According to the Technical Approval ITB-KOT-2017/0292 of 2017 the pipes can be laid in natural soil without the use of bedding by traditional and trenchless methods. We produce double-layer pipes for pressure PN-10 in diameters DN 32-500 and pressure PN-16 in DN 25-450. Both layers molecularly bonded are in black - they are inseparable. Pipes are available in coils or straight, depending on the nominal diameter.
