Frost and the Sun is a wonderful day... Does the HDPE pipes burst with frost?

Time rushes by inexorably fast! Just like summer has begun, and the second month of autumn is on its way, and #winter not far away! You need to think in advance about some issues, including pipes.

It is believed that HDPE pipes can easily withstand cold temperatures. Is it really? Let's figure it out!

What is HDPE?

HDPE- this is an abbreviation indicating that the pipes are made of low pressure polyethylene (0.941-0.965), i.e. high density polyethylene.

There are pipes made of LDPE - high pressure polyethylene. Externally, the HDPE and PDV pipes are identical, and it is quite difficult to find at least some external differences. You can find out what kind of pipe is in front of you only if you have a passport or marking.

HDPE - very dense and hard material. Scratches can only be left on it with considerable effort when exposed to a sharp object.

How does the relationship between HDPE pipes and frost develop?

Let's remember why pipes usually burst in the cold? This is due to the fact that when freezing

#water expands in volume and exerts pressure on the pipe walls. This happens with pipes made of any material.

There is only one "law" - the thinner the pipe, the higher its resistance to water freezing.

Specifically about HDPE pipes - I declare with confidence that they can withstand low temperatures and easily tolerate several freeze-thaw cycles.

Therefore, for cold terrain #HDPE pipe Is a great option. BUT! Remember the importance of good couplings and fittings. Make sure that they are made of frost-resistant materials. Otherwise, even the best quality HDPE pipes will be useless, and they will not withstand even a minimal cold snap.

HDPE is resistant to low temperatures. IN #frost the pipe may freeze if there is liquid in it. But it will not burst. The pipe will simply stretch and expand in diameter. And with gradual warming and thawing of the liquid, the HDPE pipe will return to its original parameters. This characterizes HDPE as a high-quality frost-resistant material for pipes.

Despite the good frost resistance of HDPE pipes, it is still recommended to lay them below the level of soil freezing. And for more peace of mind, electrodes or fire tools can be used when laying pipes.

In conclusion, I will say once again - HDPE pipes do not break with frost.HDPE is an excellent solution for operation in cold regions of the country. Only low-quality fittings made of materials that are not resistant to cold can fail.

So choose the right material not only for pipes, but also for their connections! And do not confuse HDPE pipes for water / heating and for cable laying! They are not the same!

If you are still faced with the problem of freezing, loosening the soil can help.
