but also on other factors. In most cases, the heat dissipation coefficient of film, rust scale and the surface condition of metal. Stainless steel can keep the surface clean, so its heat transfer is better than other metals with higher thermal conductivity. Liaocheng Suntory stainless steel provides the technical standard of stainless steel plate Stainless steel plate high-strength stainless steel plate with excellent corrosion resistance, bending workability, toughness of welding parts and stamping workability of welding parts. Specifically, Si, Mn, P, s, Al and Ni with an appropriate content of less than .% of C, less than .% of N, more than % of Cr and less than % shall meet & le; Cr Mo Si & le; & le; Ni (c n) . (Mn Cu) & le; Cr . (Ni Cu) Mo & Ge; , . & le; C, n & le; . stainless steel plate is heated to ~ ℃, and then cooled at a cooling rate of more than ℃ / S. in this way, it can become a high-strength stainless steel plate with martensite content of more than %, high strength of more than mpa, corrosion resistance and bending processability, and excellent toughness of welding heat affected zone. It can be significantly improved by reusing Mo, B, etc High stamping performance of welded parts.In the building water supply pipe system, due to the end of the glorious history of galvanized steel pipe, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some deficiencies in varying degrees, which are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. Therefore, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe.Bitam,Stainless steel and alloy tool steel (C content is expressed in thousandths), stainless C & le; .%, such as CRNI ultra low carbon C & le; .%, such as crnimo.Model & mdash; The addition of sulfur improves the processability of the material.Model & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.

The numbering rules adopt element symbols; Pinyin, open hearth steel: p; Boiling steel: F; Killed steel: B; Class a steel: a; T: special GCr: ball.　　Model & mdash; other properties are similar except that the risk of weld corrosion is reduced due to the addition of titanium.Installation works,There are various connection modes of stainless steel pipes. The common types of pipe fittings are compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. These connection modes have different application ranges according to their principles, but most of them are easy to install, firm and reliable. The sealing ring or gasket materials used for connection are mostly silicone rubber nitrile rubber and EPDM that meet the requirements of national standards. L stainless steel pipe, L stainless steel pipe and other brand products are provided for a long time. The designated products are complete and the quality is guaranteed s stainless steel pipe, which eliminates the need for useWith the implementation of China's reform and opening up, the national economy has achieved rapid growth, and a large number of urban houses, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, under certain circumstances, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm. In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first it has the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe which will play an incomparable role in improving water quality and people's living standards.Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe, so most stainless steel pipe users do not have to question this point.Fair price so most stainless steel pipe users do not have to question this point.

Stainless steel pipe packing bag is nothing more than the function of protecting the surface of stainless steel pipe,The best way to improve the quality of stainless steel pipe fittings is to change the process from ingot to billet. Due to the improvement of continuous casting process, this has become a necessary means to improve product quality.B cold rolling shall be subject to heat treatment, pickling or similar treatment, and then leveled to obtain appropriate gloss.Model & mdash; other properties are similar except that the risk of weld corrosion is reduced due to the addition of titanium.Oroshaza,High frequency welding high frequency welding: with relatively high power supply, it can reach a higher welding speed for steel pipes with different materials,Oroshaza302 stainless steel strip, it is more than ten times its high welding speed. Therefore,Oroshaza304 thick wall stainless steel pipe, stainless steel pipes for common use have a higher consumption rate. Due to the high speed of high frequency welding, it is difficult to remove burrs in welded pipes. At present,Oroshaza316L stainless steel decorative pipe, high frequency welding Welded stainless steel pipe can not be borne by chemical and nuclear industries, which is also one of the reasons.Austenitic stainless steel has good resistance to uniform corrosion, but there are still the following problems in local corrosion resistance: intergranular corrosion of austenitic stainless steel. Austenitic stainless steel will have intergranular corrosion when it is kept warm at ~ ℃ or cooled slowly. The higher the carbon content, the greater the tendency of intergranular corrosion. In addition, intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix, which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.Rockwell hardness the Rockwell hardness test of stainless steel pipe is the same as Brinell hardness test. The difference is that it measures the depth of indentation. Rockwell hardness test is widely used at present, and HRC is second only to Brinell hardness Hb in steel pipe standards. Rockwell hardness can be used to measure metal materials from very soft to very hard, which makes up for the disadvantage of Brinell method, It is simpler than Brinell method and can read the hardness value directly from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as Brinell method.
