All materials have a degree of expansion and contraction in them. The type of Liquid or gas being sent through the pipe, the temperature and pressure will also have an effect. Also whether the pipes are installed above or below ground will impact on the results. You need to be more definite in your request.: All pipes will be affected by thermal expansion. The two critical factors are the temperature of the media being transported, and the type of pipe. If the liquid is always at a constant temperature, then the pipe will reach a stable point when stasis is arrived at and then the expansion/contraction will be at a minimum. But if the pipe has a high coefficient of expansion, such as plastics, then provision has to be made for the initial expansion, either through expansion loops or expansion joints.: : Dear Sir,: : We are a group of students investigating on the various ways to lay a pipe for 100km without being affected by the thermal : : expansion.: : In Singapore, we do not have problems of large temperature difference as what you experienced over in Australia.: : We would like to know more about how you overcome such problems in Australia. Please give us some advise.: : We thank you for your kind attention and hope to receive your precious reply soon.: : Regards: : Tan Peng Yeon
