Can PE pipe freeze crack?

PE pipes do have the risk of being frozen and cracked in a low temperature environment. When the cold strikes, if you don't understand the principle and take effective protective measures, PE pipes may affect normal use due to freezing and cracking, causing many inconveniences and losses.

PE pipes will freeze and crack at low temperatures, mainly due to the characteristics of water. When the temperature drops below freezing point, the water in the PE water supply pipe and PE water pipe will freeze, and the volume of water will expand during the freezing process, about 9%. This is like putting an expanding "Ice Hockey" in a closed PE pipe, which generates huge pressure on the inner wall of the pipe. In a continuous low temperature environment, this pressure continues to accumulate. If the quality of the PE pipe is not good, the strength and toughness of the material are not enough to withstand the pressure caused by ice expansion, and the pipe will crack or even break. For example, some PE coils produced with inferior raw materials have a great possibility of freezing and cracking under the dual action of low temperature and ice expansion pressure due to the unstable molecular structure.

In addition to the quality of the pipe, the use environment and protective measures are also key factors affecting whether the PE pipe is frozen and cracked. PE pipes laid in the open air outdoors and lack effective thermal insulation measures are directly exposed to the low temperature environment, which is more prone to freezing and cracking. Especially at night when the temperature drops sharply, without any protection, the water temperature in the pipe drops rapidly and freezes, and the pressure on the pipe increases instantly, and the fragile parts are easily broken. In addition, if the PE pipe is installed without reserved expansion space, when ice expansion occurs, there is no buffer space, which will accelerate the pipe cracking.

However, this does not mean that the PE pipe is "vulnerable" at low temperatures. High-quality PE pipe, with good flexibility and impact resistance, can resist ice expansion pressure to a certain extent. Take the PE pipe produced by Hubei Aoyuan Building Materials Co., Ltd. as an example. The company uses high-quality polyethylene raw materials and adopts advanced production technology to produce PE pipes with high strength and toughness. Under normal use conditions, even in low temperature environments, as long as appropriate protective measures are taken, the risk of freezing cracking can be effectively reduced. For example, before the advent of winter, wrap the outdoor PE pipe with thermal insulation cotton, install a heat tracing device, or empty the idle PE pipe to avoid freezing water in the pipe memory.

In the water supply and drainage projects and household water transformation of Xiantao City, Qianjiang City, Tianmen City and other places, the selection of reliable PE pipe products and professional manufacturers is an important prerequisite for ensuring the safety of the pipeline in the winter. Hubei Yuyuan Building Materials Co., Ltd. not only provides high-quality PE pipes, but also provides customers with professional winter protection guidance to help customers solve practical problems. The company relies on a complete after-sales services system and technical support team to escort the use of PE pipes for every user.
