Stainless Steel Pipe Applications and Advantages

Stainless Steel Pipe/tube Applications:

Stainless steel is a recognized healthy material that can be implanted in the human body, and it is used in almost all fields involving human health. It has been widely used. Stainless steel water pipe is an environmentally friendly material that meets health requirements, can be 100% recycled, save water resources, reduce transportation costs, reduce heat loss, and avoid sanitary ware pollution. The detailed introduction is as follows:

  1. Life

Stainless steel pipes have the longest service life. From the analysis of the use of stainless steel abroad, the service life of stainless steel water pipes can reach 100 years, at least 70 years, which is as long as the service life of buildings.

  1. Corrosion resistance

One of the most prominent advantages of stainless steel pipe is its excellent corrosion resistance, which is the best among various pipes. Because stainless steel can passivate with oxidants, a tough and dense chromium-rich oxide protective film, Dr2O3, is formed on the surface, effectively preventing further oxidation reactions. Other metal pipes, such as galvanized water pipes and copper pipes, have little passivation ability. This is the key reason why the corrosion resistance of galvanized pipes is far less than that of stainless steel pipes. Stainless steel will not corrode uniformly like carbon steel, and there is no need for protective coating when used; stainless steel water pipes are used, and there is no restriction on the chemical composition of water, because stainless steel is good in water with various oxygen content, temperature, PH and hardness Corrosion resistance; stainless steel water pipes can withstand very high flow rates, even if the flow rate is greater than 40 m/s, they still maintain a very low corrosion rate, not more than 0.003 mm/year, especially suitable for high-rise water supply. Stainless steel generally does not undergo local corrosion. 304 stainless steel can tolerate up to 200 ppm of chloride content, and 316 stainless steel can tolerate up to 1000 ppm of chloride content. This conclusion is based on exposure experimental data and has been confirmed by experience. The coefficient of thermal expansion of stainless steel pipes is similar to that of copper pipes, which is 1.5 times that of ordinary steel pipes. In comparison, stainless steel pipes have the characteristics of slow thermal expansion and slow contraction.

  1. Heat and heat preservation

The thermal conductivity of stainless steel pipe is 1/25 of copper pipe and 1/4 of ordinary steel pipe, which is especially suitable for hot water transportation. The most commonly used stainless steel in the water industry is 316 and 304 stainless steel, which can meet most water treatment and customs conditions.

  1. Strength

The tensile strength of 304 stainless steel pipe is twice that of steel pipe and 8-10 times that of plastic pipe. The strength of the material determines whether the water pipe is strong, crashworthy, safe and reliable. Safety and reliability are the most important requirements for building water supply. In the case of impact by external force, the possibility of water leakage in stainless steel water pipes is extremely small. The working pressure of high-rise water supply systems is generally greater than 0.6Mpa; higher pressure requirements for pipes. Due to its excellent mechanical properties, the thin-walled stainless steel pipe can withstand high water supply pressure, up to 10Mpa or more, and is especially suitable for high-rise water supply.

Also Stainless Steel Pipes are used for Building industry machinery, oil transpiration, Food equipment, general chemical equipment, atomic energy industry components. In these fields, Stainless Steel pipes are widely used.Because of Stainless Steel pipes are Suitable for deep drawing parts and acid conveying .The steel pipe with the most production and consumption in austenitic stainless steel, which is used to produce thin-wall parts, acid-conveying pipes and structural parts, Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also often used as furniture and kitchen utensils.etc. It is also used for welding cr-ni stainless steel and stainless steel core material, non-magnetic parts and parts used in low temperature environment.
