It is obvious that the shortest straight path for the pipe seems to be most economical and viable in the first sense. There can be many reasons; 1. Shorter the pipe, lesser the capital expenditure required in procurement, welding and erection. 2. Shorter the pipe, lesser will be the pressure dropmaking it more suitable for the proper operation. 3. Shorter the pipe, lesser will be the number of supports required to support the pipe.

How To Deal With Thermal Pipe Expansion and Contraction polyethylene pipe thermal expansion process

The rate of thermal expansion usually depends on three key factors The pipe material different materials expand at different rates. So different types of plastic pipe (e.g. PP, PVC, PE etc) and different types of metal pipe (e.g. steel, copper, iron) will have different coefficients of expansion.How To Deal With Thermal Pipe Expansion and Contraction polyethylene pipe thermal expansion processThe rate of thermal expansion usually depends on three key factors The pipe material different materials expand at different rates. So different types of plastic pipe (e.g. PP, PVC, PE etc) and different types of metal pipe (e.g. steel, copper, iron) will have different coefficients of expansion.IMPORTANT INFORMATIONHigh density polyethylene pipe (HDPE) has several properties that make it very different from tradi-tional water works pipe materials Coefficient of thermal expansion is over 10 times that of DI and steel and 3 times that of PVC. In practical terms, this means HDPE pipe

Is thermal expansion and contraction of HDPE pipe a problem?

The key is management of the resultant thermal strain. As with all materials, expansion and contraction must be taken into consideration when designing a HDPE piping system. Buried pipelines usually do not move due to soil friction. However, thermal effects must be considered for above grade applications. The unrestrained coefficient of thermal expansion for HDPE pipe is approximately 9x10-5 in/in/oF.Module 162 Multilayer composite polymer-al-polymer pipes polyethylene pipe thermal expansion processA significant advantage over solid plastic pipes is that multilayer pipe has reduced thermal expansion, with the intermediate aluminium layer maintaining the expansion rate to about 10% of that of a solid PE-RT pipe. Practically, this would mean that a multilayer pipe would expand 2mm for every metre run as its temperature rises from 0°C to 80°C.Natural gas pipeline systems on site distribution 2019 polyethylene pipe thermal expansion processAs a result, it is limited to lower pressure applications (< 125 psig). Pipe wall thickness requirements are greater than for metal piping, resulting in smaller inside diameters for a given size pipe. PE has a higher coefficient of thermal expansion than metal. PE has the potential to

The thermal movement rate (Figure 4.5) in mm/m for 30°C= 6.0 mm/m. The total thermal movement is then 6.0 x 100 = 600 mm. Where pipes are buried, the changes in temperature are small and slow acting, and the amount of expansion/contraction of the PE pipe is relatively small.Pipestar Australia HDPE Industrial PlasticsThe co-efficient of thermal linear expansion of polyethylene varies with temperature but at ambient lies in the range 1.2 to 2.4 x 10-4 per degree C. In broad terms, this is about twenty times that of steel, and therefore unrestrained pipe will expand or contract much Properties and applications of HDPE or High Density polyethylene pipe thermal expansion processHDPE (High Density Polyethylene) After its experimental preparation in the 1930s, the application in high frequency radar cables during World War II, gave impetus to its commercial production. This thermoplastic is available in a range of flexibilities depending on the production process. High density materials are the most rigid.
