Water pipes are generally made of spiral steel pipes, which are welded by submerged arc welding. Because the welded pipe is spiral, the liquid pressure is distributed on each side of the pipe to enhance the strength of the pipe. If the straight seam steel pipe is used, the large pipe is usually rolled up and welded directly by steel plate, which requires large steel plate, which greatly increases the difficulty of production, so spiral pipe is used for large pipe diameter.




Selection and maintenance of large-caliber spiral steel pipe as water pipeline: For cleaning domestic water pipeline, to master the correct method, we must adhere to prevention and do a good job in daily maintenance. Water pipe. In the decoration and renovation of family houses, the best way to prevent leakage of water supply and pipes is to strictly comply with the technological requirements to ensure the quality of the project. In addition, domestic water pipelines should have a sense of regular maintenance.


Large diameter spiral steel pipe shall conform to the manufacturer's name, brand and specifications. The water supply pipe is connected by threads, and the exposed threads should be exposed at the joint. When the equipment is finished, it should be fixed with pipe clamp in time. Pipeline and pipe fittings or valves should be firmly connected without any loosening. In the future, the installation of pipes should be checked by water, and the leakage should be checked by visual inspection and hand feeling. Check whether all faucets and valves are flat, whether the opening is sensitive, whether the water is dredged and whether there is leakage. Check whether the water meter is working properly.


Winter protection method of water spiral pipe: professional pipe maintenance agent can be used to regularly clean, disinfect and sterilize sewage pipe, keep the pipe unblocked, and prevent the pipe from becoming a breeding ground for pathogens.  When cleaning pipelines, professional pipeline maintenance products should be used to achieve sterilization, deodorization, cleaning, anti-blocking and other functions. When choosing maintenance products and dredging products, we should pay attention to the safety of products, select products with high sterilization rate and test them by professional organizations.
