With the implementation of China's reform and opening up, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, 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, reliability, 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.The petrochemical industry, including the chemical fertilizer industry, has a great demand for stainless steel pipes. Stainless steel pipes are mainly used in this industry, including, , l, etc., with an outer diameter of about ￠ - ￠ and a wall thickness of about mm-mm (generally medium and low pressure transmission pipes with a specification of more than & phi; mm). The specific application fields are: furnace pipes, material transmission pipes, heat exchanger pipes,PalinStainless steel pipe agent, etc.Palin,Doing well in marketing strategy innovation is a very key factor for every manufacturer joining stainless steel pipe to realize the marketing effect of market competition; However, due to the different characteristics of each market, stainless steel pipe manufacturers need to make different marketing strategy adjustments; As the saying goes, & ldquo; No matter what kind of cat it is, catching mice is a good cat& rdquo; Professional projects include: stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe and other related businesses. Merchants who hope to have this business please. This is also true in the marketing strategy. Therefore, manufacturers of stainless steel pipes need to make marketing innovation at any time to match the changing market conditions.The welding of stainless steel pipe is usually composed of backing welding, filling welding and cover welding. Backing welding of stainless steel pipe is a key link in stainless steel pipe welding, which is not only related to the quality of engineeringHormigueros,Low temperature processing of stainless steel pipe --- martensite series stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote martensite quenching. It is suitable for stainless steel easy to produce residual austenite.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.The surface resistance is less than mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.

Since the beginning of last year, foreign countries have frequently carried out & ldquo; Double inverse & rdquo; This has a great impact on China's stainless steel casting industry. Export is a large part of the development of China's stainless steel industry and occupies a huge market share in its industrial development. In the face of economic downturn and slow development, the development of China's stainless steel industry should constantly improve product quality, Better develop overseas trade and deal with trade protectionism, combine products with environmental protection, energy resources and cultural environment, and improve the competitiveness of stainless steel products. Only in this way can we achieve an invincible position in foreign trade.It is also frequently launched on the surface. If you want to buy a stainless steel water supply pipe with quality assurance, what should you choose?The experimental ice load of concrete decorated stainless steel pipe is the highest in the cold areaHighly recommended,Stainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance, which can not be compared with cast iron pipes, it shall not be too large to prevent the pipe from being out of round.

Welding of stainless steel pipe argon arc welding stainless steel pipe: it is required to have deep penetration no oxide inclusion, and the heat affected zone can be as small as possible. Argon arc welding maintained by tungsten inert gas has good compliance high welding quality and good penetration function. Its commodities are widely used in chemical, nuclear and food industries.target,Stainless steel and alloy tool steel (C content is expressed in thousandths), such as thousandth of CrNi (i.e. .% C), stainless C & le; .%, such as CRNI ultra low carbon C & le; .%, such as crnimo.Hot dip galvanized sheet hot dip galvanized sheet, which immerses the sheet into the molten zinc bath to make its surface adhere to a layer of zinc. It is mainly produced by continuous galvanizing process, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate. Liaocheng Suntory stainless steel plate weighing method: stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel basic weight (density)Since the back is not filled with argon, its advantages are obvious, mainly for its simplicity and low cost, which is suitable for installation on the construction site. However, due to its structural characteristics,Palin5mm thick stainless steel plate, flux cored welding wire has high requirements for welders during operation, with fast wire feeding speed and high wire feeding accuracy. It is difficult to master. Welders should be specially trained and skilled before they can participate in welding in Yangba, Nanjing And foreign construction sites,PalinS32101 stainless steel plate, we have successfully solved the problem that argon cannot be passed through the junction and repair port.Palin,Solution treatment. The main purpose of water quenching after heating the steel to ~ ℃ is to dissolve the carbide in austenite and keep this state to room temperature, so that the corrosion resistance of the steel will be greatly improved. As mentioned above, in order to prevent intergranular corrosion, solid solution treatment is usually used to dissolve CrC in austenite and then cool rapidly. Air cooling can be adopted for parts, and water cooling is generally adopted.Stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable. The successful development of pipeline and new reliable, simple and convenient connection makes it have more irreplaceable advantages of other pipes. It will be used more and more in engineering, and the use will be more and more popular. It has a good prospect.Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals and its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.
