Stainless steel pipe is a hollow strip steel, a large number of used for conveying fluid pipe, such as oil, natural gas, water, gas, steam, etc., in addition, doing bending and torsional strength phase at the same time, the weight is lighter, it is widely used in the manufacture of machinery parts and engineering structures. Also commonly used for the production of various kinds of conventional weapons, barrel, shells, etc. Safe and reliable application of stainless steel pipe, stainless steel tube, health, environmental protection, economic applicable piping of thin wall and new methods for reliable, simple and convenient connection of successful development, make its have more other pipe irreplaceable advantages, the application of the project will be more and more, use will be more and more popular, good prospect.
Along with our country the implementation of the reform and opening up policy, the national economy to obtain rapid growth, urban housing, public buildings and tourist facilities built in great quantities, to the hot water supply and water supply is put forward new requirements. Water quality problems, in particular, people pay more and more attention to, also enhances unceasingly. Galvanized steel pipe a commonly used pipe corrosion because of its easy, under the influence of national policy, will gradually become relics, plastic pipe, compound pipe and copper pipe became common tubes of pipe system. But in many cases, the stainless steel tube has more advantages, especially the wall thickness of only 0.6 ~ 1.2 mm of thin-walled stainless steel tube in high quality drinking water system, hot water system and water supply system will give top priority to safety, health, have a safe and reliable, health, environmental protection, economy applicable, etc. Engineering at home and abroad has been proved to be the best comprehensive properties of feed water system, one of the new, energy saving and environmental protection of pipes, is also a kind of very competitive water supply pipe material, to improve water quality, improve the level of people's life play a role of incomparable. In construction to the piping, the galvanization steel tube is over one hundred years of glorious history, a variety of new plastic pipe and pipe to get rapid development, but a variety of pipe still exist some shortcomings in different degrees, is far from being fully meet the needs of the water supply system, the state of drinking water and related water quality requirements. As a result, experts predicted: building water supply pipe will eventually back to the time of metal tube. According to the application of foreign experience, in the metal tube that thin-walled stainless steel tube is one of the best comprehensive properties of steel tubes.
