The stainless steel electric heating tube is sheathed with stainless steel, magnesium oxide rod as core, magnesium oxide powder filler, and nickel-chromium wire as heating wire. It can be roughly divided into single-head electric heating tube and double-head electric heating pipe.
In winter, stainless steel electric heating pipes are prone to freeze cracking, causing serious water leakage. Special attention should be paid to the prevention and inspection of stainless steel electric heating tubes. In addition, the classification and use of stainless steel electric heating pipes should also be understood. First of all, we need to understand the undesirable factors that stainless steel electric heating pipes are prone to freeze cracking.
1. Antifreeze equipment (antifreeze plugs, antifreeze wooden boxes, etc.) Should be installed outdoors on faucets and pipes.
2. Houses with water pipes should be attached to door seams and window seams, and pay attention to indoor insulation.
3. There is ice in the house. Sack slices and straw rope should also be wrapped.
4. The covering sand washed by flooding in the rainy season should be filled before winter to prevent the soil layer from being too shallow and the water pipe from freezing and cracking.
5. Once the water pipe freezes, do not burn it with fire or boiling water (this can damage the sudden expansion of the water pipe and faucet). Wrap the faucet in a hot towel to help freeze.
