Round HDPE Pipes
Round HDPE Pipes:
In third generation (high density PE80 and PE100) ESCR is improved by branching only the long chains, thereby not decreasing the density (maintaining stiffness / creep resistance). Short chain branches inserted on the longer molecules ensure an efficient increase of the resistance to stress cracking in the long term, while creep resistance is maintained through high density (no branches on short chains that crystallize easily).

PE Classification ISO 4427 - 2007(E).
In the early 1990s, a new type of PE material was developed in Europe with higher hoop strength giving rise to the PE100 classification. These materials are sometimes termed bimodal or 3rd generation because of the two stage polymerization process used to produce them. PE100 materials produce stronger pipes which are used for higher pressure operation in gas and water distribution systems.
A design engineer may wish to apply a greater safety factor depending on operating conditions and environmental considerations.
If you are looking for rugged dependability, light weight, long lasting service, trouble-free installation, flexibility, superior flow rates, high chemical resistance and extremely high corrosion resistances without compromising on efficiency, Jain PE piping systems are the perfect solution.
