With the economic growth and the improvement of people's living standards, the good comprehensive performance of stainless steel and the advantages of durability, beauty, long service life, and high cost-effectiveness have been recognized by people. From gorgeous hotels, commercial buildings, stadiums, churches, municipal, bridges, tunnels and other public facilities to residential houses; from decoration, roofs, reinforced concrete, urban water supply projects to water tanks and baths in residential houses, stainless steel is used more and more widely.
The early application of various seamless steel pipes in the field of construction engineering began in the 1930s. For example, the Savoy Hotel in London built in 1929 should use stainless steel as ceiling and wall decoration, and it has remained in the sea and environmental pollution for 70 years. With its beautiful appearance, the American Chrysler Building built in 1930 uses stainless steel as the roof and surface decoration. It has only been cleaned twice so far. It stands in the large building complex in New York.
In which areas are seamless steel pipes most widely used?
1. Application in decoration engineering. In addition to walls, cylinders, automatic retractable doors, roller shutter doors, step fence handrails, balcony handrails, rain downspouts, flag poles, street lamp poles, arcade frames, kitchen and bathroom countertops, sinks, brackets, etc. in residential houses, in which the application is increasing day by day. The grades of steel used in decoration engineering are mostly 304, and 316 is also used.
2. Application in water supply engineering. With the rapid economic development and the improvement of people's living standards, a large number of urban residential buildings, public buildings and tourist facilities have been constructed, and new requirements have been put forward for the supply of domestic water and hot water. Water quality issues have attracted much attention. Galvanization is a common pipe material in water supply projects. Because steel pipes are easily corroded, it is difficult to improve water quality due to the phenomenon of "red water" and "green water", and experts predict that they will gradually withdraw from the stage of history due to more leakage and short service life. Plastic pipes, composite pipes and copper pipes It is not as superior as stainless steel seamless steel pipes in terms of safety, reliability, sanitation, environmental protection, economy and durability. Domestic and foreign engineering practices have proved that stainless steel is the energy-saving and environmentally-friendly pipe with the best comprehensive performance in the water supply system and the best guarantee of the water supply quality.
