With the arrival of winter, a topic of concern for the pipeline industry has emerged, which is the cold and frost resistance of pipelines. Many hard pipes on the market are prone to bursting at once when the water in their pipes freezes and expands.

And there is no need to worry about this issue with TPU flat hoses, because TPU layflat hoses only support themselves due to pressure inside the tube when in use. Even if there is water in the TPU layflat hose when not in use, it will not be in an extreme state and can accept swelling caused by water freezing. However, the cold resistance issue of TPU layflat hoses cannot be ignored. Each type of hose and hose has a working temperature range during use, and exceeding or falling below this temperature range can easily cause hose damage or rupture. Ordinary engineering hoses will become hard and brittle at temperatures below minus a few degrees Celsius due to material and process reasons, forming non visible cracks on the surface. At the same time, the strength of the material itself will be greatly reduced. At this time, when the hose is in a high-pressure working state, it is easy to damage or even burst. So many of our customers have this concern, but our high-pressure TPU flat hose does not need to worry about it. Firstly, our material is polyurethane, and its working temperature range is -46 ℃~76 ℃. Within this range, the physical properties of the hose do not change much, and its use is not affected. This temperature range actually covers most application scenarios, so our customers do not need to worry about whether the hose can be used in high cold temperatures.
