Energy saving thin-walled stainless steel pipes and fittings Introduction
The new building of the water supply pipe is hot matter . Thin-walled stainless steel pipes and fittings , sanitary and durable , looks beautiful, green energy, engineering has been recognized at home and abroad . Thin-walled stainless steel pipes and fittings have a variety of mature connections , easy installation, safe and reliable, due to reduced wall thickness, reducing the cost , so now widely applied ripe .
In foreign country thin wall stainless steel pipe applications has become universal application of thin-walled stainless steel tubes abroad starting in the 1960s , at present, the developed countries in the application of building water supply , water treatment systems are increasingly common . Britain, Germany, the U.S. and Japan have stainless steel pipe standards , there are also ISO and DINEN standards. The United States under the Clean Water Act enacted AN-SI/NSF61-1997a National Standard / National Health Fund international standards , clearly defined for the treatment of drinking water only stainless steel and ductile metal materials . Health Canada , RvA ( Dutch Accreditation Council ) and the World Health Organization also confirmed this standard. Material meets the requirements of the standard stainless steel AISI304, 304L, 316 and 316L and so on.
Second, the domestic development of thin-walled stainless steel tube profile ? Domestic water supply system in the building , galvanized steel is over a hundred years glorious history, as the representative of aluminum pipe composite pipe and PE, PP-R , such as the rapid development of plastic pipe However, there are some disadvantages of this pipe , far less than the national drinking water on water quality requirements. Therefore, the experts predicted: building water pipe will eventually return to the era of the metal tube. Stainless steel thin-walled metal tubes found in the best overall performance for the pipe, the domestic market is very promising. To this end, China promulgated the relevant standards.

Third, thin-walled stainless steel tube performance and features ? Performance and characteristics of thin-walled stainless steel pipe ?
1, the product life of up to 50 years.
2 , corrosion resistance : stainless steel with very good corrosion resistance, stainless steel resistant to chloride 200ppm , 1000ppm 304 316 stainless steel can withstand natural water chloride corrosion, tube surface in contact with oxygen will automatically generate highly dense corrosion chrome protective oxide film , in the design of stainless steel when there is no need to consider corrosion allowance .
3 , impact resistance : plumbing strength galvanized steel is 2 times 3 times brass . Joint pressure 2.5-5 mpa, anti- pull force > 5000n. The impact of high-speed water -resistant , can withstand high velocity impact of 30m / s , so the flow can withstand administered mouth, elbows , valves and corrosion caused by the vortex pump ;
4 , smooth inner wall joints : the product interface , such as pipe diameter , water resistance is small, with large diameter tubes than other traffic .
5 , thermal conductivity , good insulation properties : Its thermal conductivity is brass 1/25 , is a steel pipe , 1/ 4 , thermal expansion and contraction is slow, only PPR pipe , UPVC pipe 1 /4.
6 , Good Health : Long-term use is not easy to scale, non-toxic , non- fouling , to prevent secondary pollution pipeline , compared with other pipes, heavy metals leaching into the water (Ni, Cr, Mo) the least amount , leaching into the water pure metal (Na, Fe, Ca) the least amount ; were able to meet during the life of the country , Japan, Europe and other international drinking water standards.
7 , saving material : As a result of thin-walled , galvanized pipe weighs only 1/3 , saving a lot of material , reducing weight , especially for high-rise buildings . Products can be 100% recycled, in line with national industrial policy.
8 , simple construction : Operating time is short: The product is non- threaded connections, no complicated threading operations, before and after treatment without welding , oil pollution or welding pollution -free construction cutting or convergence time , using a special tool sealed pressure pipe fittings connection quickly.
9 , economy: stainless steel tube is one of the longest tube life species, water pipes clean energy forever . Milan Canegrate water treatment plants, carbon steel and stainless steel for its lifetime costs itemized analysis by concludes : 30 -year life cycle, the lowest rate in the pipe network , its maintenance and update costs are the lowest cost of stainless steel the . The best of the 21st century , a new , energy-efficient and environmentally friendly types of pipe used in water supply systems overall performance.
10 products look beautiful : Whether a new installation, or for a long time been used, with the new environment can support .
11 , the application of a wide range. Product application areas from the current building water supply, water supply pipes extended to direct heating, gas pipelines and the food, pharmaceutical, chemical , electronics, and fire and other industries .
