hdpe pipe thermal expansion in poland Despriction

### IMPORTANT INFORMATION

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 shrinks 10 times as much as DI and 3 times as much as PVC when it gets cold. This can loosen any fittings installed on it. Also, its length shrinks 1 inch per 100 feet of pipe length with a 10° F What is high density polyethylene pipe?What is high density polyethylene pipe?High 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.IMPORTANT INFORMATION What is the coefficient of thermal expansion?What is the coefficient of thermal expansion?For materials, such as thermoplastics, for which for most practical purposes thermal expansion may be assumed to be isotropic the volumetric coefficient of thermal expansion is approximately three times the linear coefficient. The values in Table A-1 are for the convenient temperature range of approximately -30°C (- 22°F) to +30°C (86°F).TR-21 Thermal Expansion and Contraction in Plastics Piping hdpe pipe thermal expansion in poland

### What is the difference between HDPE and HDPE?What is the difference between HDPE and HDPE?HDPE has a lower modulus of elasticity and higher coefficient of thermal expansion than other pipe materials. These properties cause HDPE pipe to expand and contract much more from changes in temperature and/or pressure than other piping materials.IMPORTANT INFORMATION

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.
