How to deal with freezing in water pipes.

Best answer: External heating method: When the water pipe is frozen, steam, hot water, fire roasting, electric heating and other means can be used to turn the frozen water in the water pipe into water and discharge it, thus achieving the dredging effect; In-pipe heating method: Remove the pipe, and inject steam, water, salt water, etc. into the pipe with a hose thinner than the pipe, so as to melt the ice in the water pipe and clear the water pipe.

In-pipe heating method: the pipe is removed, and steam, water, salt water, etc. are introduced into the pipe with a hose thinner than the pipe to melt the ice in the water pipe and dredge the water pipe.

Outside-pipe heating method can be used for thinner pipes, and inside-pipe heating method can be used for thicker pipes.

water pipe:

Water pipes are water supply pipes. Water pipes in modern decoration are all built with buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes lined with plastic, copper pipes and stainless steel pipes. The second category is plastic-clad metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes. The third category is plastic pipe, such as lead pipe and polypropylene fiber pipe.

In the past, the pipes used for water supply were mainly cast iron pipes. Sand mold cast iron pipes are mainly used outdoors, and galvanized cast iron pipes are used indoors. However, after several years of use, it is easy to produce a large amount of rust and scale, which will breed bacteria and seriously endanger human health. The state has stipulated that sand casting process pipe fittings and cold galvanized cast iron pipes should be eliminated from June 1, 2000, the use of hot galvanized cast iron pipes should be gradually restricted, and aluminum-plastic composite pipes and new plastic pipes should be popularized.

The state also stipulates that all kinds of pipes and fittings related to drinking water pipelines must be approved by the health department before they can be sold.
