PERT Piping System

Smart Joint was found in 1992, who is the earliest company dedicated in PE piping system development. We focus on PE pipe, fitting and fusion machine production. For more than 20 years, smart joint played a great role in promotion of PE into gas and water industry in China and has witnessed the blooming growth of the whole industry.
Now Smart Joint see another business chance in hot water piping system and chemical industry, and is dedicated to introduce PERT into these area. There will be a fast revolution, all steels pipes will be replaced in recent years to offer a reliable PERT piping system for the city and improve the life where hot water is required. Smart Joint are capable of produce PERT II pre-insulated pipe and PERT II Fittings up to 400mm.
PE-RTII is a high performance hexane-based compound primarily intended for hot(80°C) & cold water pipe as well as demanding industrial pipe applications.

Key characteristics are:
1: a PE-RT Type II classification;
2: a superior resistance to slow crack growth coupled with a MRS of 10 MPa, ensuring safe and durable pipe systems operation;
3: a broad bimodal molecular weight distribution offering outstanding processing properties from small bore pipes to large diameter pipes extrusion, for both mono- and multilayer applications;
4: an optimized formulation of additives providing excellent long-term stability in service at elevated temperatures.
5: It combines excellent processability with elevated temperature performance and long term stability.
6: Typical applications include hot & cold water domestic plumbing, underfloor heating, radiator connections, infrastructure surface heating, cooling and deicing industrial applications e.g. in corrosive environments.
It offers outstanding processing properties. Small bore mono- and multi-layer pipes can be produced at high speed while maintaining an excellent gauge control.
Conversely, high throughput extrusion of large diameter industrial pipes is made possible on standard HDPE equipment thanks to the low sag behavior of the resin.

Comprare to steel pipe:
