Tensile Performance of HDPE Water Supply Pipe

Where is HDPE water supply pipe used?

HDPE water supply pipe is widely used in engineering building water supply pipe, buried drainage pipe, engineering building centralized heating, gas pipeline, welding and communication equipment maintenance waterproof casing, industrial grade pipeline, agricultural and livestock pipeline, etc. because of its unique advantages. Its main applications are power supply in big cities, natural gas in big cities and agricultural irrigation. The excellent tensile properties make the use of the commodity more common. The following will introduce the tensile properties of PE water supply pipe in detail.

 

In HDPE water supply pipe DOP applications, the polymer material has the necessary physical properties. The physical properties of most polymers are superior to the tensile properties of other HDPE fittings. Many customers believe that when HDPE fittings are used as water supply pipe, we do not care about the tensile performance as a performance indicator, but when using raw materials, we need the physical properties of polymer materials.

 

Generally there are heat shrinkable film and shrinkage reduction film that require high tensile properties of raw materials. In fact, specific HDPE fittings products usually have a tensile performance of about 200%. As with HDPE drag fittings applications, this statistic is ideal and the stretching properties are too good to be true. Due to overstretching, there is no doubt about the ring steel of HDPE water supply pipe accessories.

What is the role of tensile properties of HDPE water supply pipe? 

Many customers are not interested in the mechanical properties required when polymers are used as materials. In most applications of polymers, mechanical properties are arguably more important than other physical properties. Polymers have the broadest range of mechanical properties of any known material. This is because macromolecules consist of long chain molecules with significant relaxation properties for molecular motion. When polymers have high elongation values, ordinary PE has an elongation at break of 90% to 950% (LLDPE, a linear low density polyethylene, has a higher elongation value). Through special manufacturing processes, some materials can be stretched to length values in excess of 1000%, and ordinary polymer materials can have elongation at break of 50% to 10%. Generally speaking, heat shrinkable film, stretch film, etc., require high tensile performance of the material.

 

HDPE water supply pipe has good tensile property, not easy to damage and long service time. It is especially suitable for water supply application. Maintenance is carried out during use to extend the use time.
