Brief introduction of water-cooled hard pipe

1. Which is better, water-cooled hard pipe or hose?

As far as the interface is concerned, the hose should be safer. I made a hard pipe for my friend (the first time), so I changed the hose for myself these two days. After reading the screws, it is really much safer. The hard pipe is rubber plug, and the contact surface is not large, so I have been worried that there will be problems with the rubber plug, but my friend's hard pipe machine has been used for about half a year, and there is no problem.

In fact, when making hoses and hard pipes, the main consideration is installation and maintenance. Because the hard pipe is straight, it has a good impression and looks much better than the hose, but it is really convenient for beginners to put on the hose. The problem with rigid pipes lies in the treatment of dimensions. It is easy for novices to measure the size inaccurately, which leads to the scrapping of pipes, and it is also time-consuming to cut elbows.

As far as coolability is concerned, the difference between soft and hard can be ignored and need not be entangled.

3. Common sense: Teach you how to prevent the water pipe faucet from freezing.

According to past experience, the freezing weather of rain, snow, strong wind will have a great impact on urban traffic, water supply and power supply. Nanchang water supply department has issued anti-freezing tips for water supply facilities.

Nanchang water supply department reminds the general public to make timely preparations to avoid freezing of outdoor water pipes and water meters caused by sudden drop in temperature, which will affect normal water use. Users who install pipelines in the north and windward side should pay special attention. In addition, galvanized iron pipes are easier to freeze than hot melt pipes, and should be fully insulated and bandaged. At the same time, the water supply department reminds all owners, property management companies and residents to do a good job of anti-freezing and heat preservation of water facilities such as residential pipelines, building risers and roof water tanks in advance.

For the water meter installed outdoors, you can choose a thick towel or cloth to wrap the water meter, or you can turn on the faucet at home to let the water flow out in a linear way and let the water in the water pipe move, so as to prevent the water meter and water pipe from freezing. If the water meter has frozen, wrap it with a hot towel and sprinkle it with warm water (not exceeding 60 degrees Celsius) until the ice in the pipe melts and the water flows out smoothly. Do not pour boiling water or bake with fire to avoid damaging the plastic parts in the water meter.

Outdoor exposed water pipes and indoor water pipes can be wrapped with thermal insulation materials (such as old clothes, cotton wool, sponge, etc.). ), and a layer of waterproof material (plastic sheets, etc.). ) wrapped in insulation materials to prevent them from freezing. If the faucet and water pipe are frozen, you can blow them with a hair dryer, or wrap them in a towel and slowly pour in warm water. At the same time, you can tap the water pipe gently with a hard object until the ice in the pipe melts and the tap water flows out smoothly.
