PE Pipe Wall Thickness for raised temperature

The wall thickness of pipes are based on the maximum allowable hydrostatic design stress at 30°C water temperature for 50 years of life. In case of variation in water temperature, the working pressure needs to be modified as per given chart. However, occasional rise in temperature as in summer seaoson with concurrent corresponding reduction in temperature during night has no deleterious effects on the life and working pressure of PE pipes

Why we choose polyethylene (PE) pipes as against AC/CI or DI?

Polyethylene pipe systems offer significant advantages over ductile iron, steel and cement systems. Some of its advantages are as follows

Longevity: PE pipes have the Long track record of excellent performance, approaching 100 years worldwide.
Corrosion resistance: PE is basically chemically inert. This pipe system does not rust and corrode. This system resists chemical attack from aggressive soils. There is no need for protective layer or finishing process. PE pipe has very good abrasion resistance also.
Leak tight: Butt fused joints create a homogenous system. The fusion weld for this system is very strong Therefore, unlike ring type joints or the other mechanical jointing systems, there is no risk of leakage resulting from joint distortion.
Optimum flow rate: Smooth inside pipe surface allows for a high Hazen-Williams “c” factor. “c” remains constant throughout the lifetime of the system due to an innate high resistance to scale and biological build up.Polyethylene (PE) is also biologically inert.
Excellent water hammer characteristics to withstand surges: The inherent properties of polyethylene allow the system to significantly lower the effect of surges compared to PVC and ductile iron systems.
Flexibility: PE pipes can be coiled and supplied in length of up to 300m for small diameter pipes. This feature is one of the ma ny contributions to cost savings during the installation process.
Resistance to geological conditions: PE piping systems have inherent resistance to ground temperature fluctuations and earth instability because of high impact and breakage resistance.
Seismic Resistance: The toughness, ductility and flexibility of PE pipe combined with its other special properties, such as its leak-free fully restrained heat fused joints, make it well suited for installation in dynamic soil environments and in areas prone to earthquakes.
Abrasion Resistance: PE pipe is a frequent choice for the transport of granular or slurry solutions, such as sand, fly ash and coal. The advantage of polyethylene in these applications is its wear resistance, which for example when conveying fine grain slurries has been shown in laboratory tests to be three to five times greater than for steel pipe. PE pipe has elastic properties that under proper flow conditions allow particles to bounce off its surface. This feature combined with PE’s toughness results in a service life that exceeds that of many metal piping materials. There are several factors that affect the wear resistance of a pipeline. The concentration, size and shape of the solid materials, along with the pipe diameter and flow velocity, are the major parameters that will affect the life of the pipeline.
High strain allowed virtually eliminated failure due to freezing pipes.
