Stainless steel is inherently superior to many other tubes
Stainless steel is inherently superior to many other pipe materials and has been proven by many years of practical experience both at home and abroad to be a century-old green pipe with the lowest life cycle cost, the highest overall performance and great potential for growth. The thin, strong oxide film on the stainless steel surface provides stainless steel with excellent corrosion resistance in all water qualities, including soft water, excellent corrosion resistance even when used in the ground, and good erosion resistance.
Must promote the use of stainless steel water pipes. Stainless steel pipe strength is very high (galvanized pipe is 2 times, steel pipe 3-4 times, PPR pipe 8-10 times), but also has good ductility and toughness, low temperature does not change brittle; on the collision can have a strong (Austenitic stainless steel absorbs 2.5 times more energy than carbon steel during deformation), good shock and impact resistance, excellent wear and fatigue resistance, good high temperature strength, excellent fire and heat resistance Radiation performance.
Stainless steel thermal conductivity is low (is the steel pipe 1/25, is the pipe 1/4), thermal expansion and contraction slow. Stainless steel pipe high grade, the price is not high. In fact, the choice of stainless steel pipe not only investment is not high, the most noteworthy is its very low life cycle cost, which is the economic advantages of other materials unmatched by the biggest advantage.
In the construction of plumbing, since the galvanized steel pipe has ended a hundred years of glorious history, all kinds of new plastic pipe and composite pipe developed rapidly, but all kinds of pipe to varying degrees there are some shortcomings, can not fully adapt to the water supply pipe Department needs and national drinking water and related water quality requirements. Therefore, the experts predicted that: building water supply pipe will eventually return to the metal pipe era. According to foreign application experience, it is concluded that the thin-walled stainless steel pipe is one of the pipes with the best overall performance in the metal pipe.
The successful development of stainless steel pipe is safe, reliable, hygienic and environment-friendly, economically applicable, pipe thinning and a new type of reliable, simple and convenient connecting method make it more irreplaceable for other pipe materials. The application in engineering will be more and more , The use will be more and more popular, the prospect is good.
In many cases, stainless steel pipe has more advantages, especially the thin-walled stainless steel pipe with a wall thickness of only 0.6 ~ 1.2mm, which is safe for drinking water systems, hot water systems and safety and hygiene water supply systems Reliable, health and environmental protection, economic and other characteristics. It has been proved by domestic and foreign engineering practice to be one of the best water supply system comprehensive performance, new type, energy-saving and environment-friendly pipes and also a very competitive water supply pipe. It is sure to improve water quality and improve people's living standards. Comparable effect.
With the implementation of China's reform and opening up policy, the rapid growth of the national economy, the massive construction of urban residential buildings, public buildings and tourist facilities put forward new requirements on the supply of hot water and domestic water supply. Especially water quality problems, people pay more and more attention to the requirements are also constantly improving. The common pipe of galvanized steel pipe will gradually withdraw from the stage of history because of its corrosiveness under the influence of relevant national policies. Plastic pipe, composite pipe and copper pipe have become common pipe materials of the pipe system.
Stainless steel water pipe is a longevity life expectancy low cost materials, green health materials, sustainable development of environmentally friendly materials. Developed countries based on human health first and life cycle cost considerations, the application of stainless steel water pipes have become increasingly popular. After China entered the 21st century, especially after China's accession to the WTO, it is also in urgent need of improving product quality to change plastic pipe and composite pipe far from being able to fully meet the needs of water supply pipelines and meeting the current state of drinking water quality requirements of the country, so as to maximize people's living standards The goal of quality.
