Sewage & Waste

Combines the strength of Polymer Concrete with the enhanced corrosion resistance of GRP. The Pipe consists of an internal and an external composite liner of glass reinforced plastic sandwiching a core of Polymer Concrete.

The two liners which act as permanent formwork during casting of the pipe, bond to the polymer concrete to become an integral part of each other. This bond gives a major increase in strength. The ring beam strength of this pipe is over twice that of a plain Polymer Concrete Pipe.
 

The outside of the pipe has a smooth glossy exterior consisting of a glass reinforced liner. This gives a total external impervious surface to the pipe. The pipe does not absorb water during the drive, and the weight you start with is the weight you finish with. The smooth exterior face also helps reduce friction thus reducing jacking loads.

Simona Polypropylene (PP) is the most widely used material for chemical-technical applications. Compared to PE, it displays greater rigidity particularly in the upper service temperature range (up to +100°C). Its key characteristics also include excellent chemical resistance, good long-term properties when exposed to various substances and high stress crack resistance.

There are two types of polypropylene: homopolymers (PP-H) and copolymers (PP-C). PP-H consists entirely of a combination of propylene monomers and covers a service temperature range from 0°C to +100°C. PP-C features a chemical combination of propylene monomers and ethylene monomers, which increases the material's impact strength at low temperatures. PP-C covers a service temperature range from –20°C to +80°C and is less rigid than PP-H. SIMONA offers best-in-class products of the highest possible quality in both categories – for applications that demand maximum safety and reliability.
