Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.Clamping connection steps: cut off the pipe according to the required length. When breaking the pipe, it shall not be too large to prevent the pipe from being out of round.Ioannina,Theoretical weight: Cr Ni austenitic stainless steel austenitic stainless steel (kg / M) s-wall thickness (mm)Stainless steel pipe, which was consumed and used at the end of the s, is a rebirth group emerging in today's pipe range. It has been widely used in the construction of water supply and direct drinking water pipelines. Stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing wall thickness and money, so as to facilitate further implementation. In order to promote stainless steel pipe, since the s, China has started to reduce wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical effect of stainless steel pipe makes the stainless steel pipe lose its application and expand quickly. There are various connection modes of stainless steel pipes. The rare types of pipe fittings include contraction 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 methods have different application ranges according to their principles, but most of them are convenient, nitrile rubber and EPDM that meet the requirements of national specifications, which eliminates the worries of users. In the construction of water supply pipe system, due to the glorious history of galvanized steel pipe, all kinds of new plastic pipes and composite pipes have been lost and developed rapidly but they are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. In direct drinking water, stainless steel pipe system is undoubtedly one of the best. At present,IoanninaStainless steel industrial pipe, hotels and public places at the international level have been equipped or are equipped with direct drinking water pipelines. In many cases, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm has the characteristics of safety reliability,Ioannina303 stainless steel welded pipe, environmental protection sanitation, hot water system and water supply system that puts safety and sanitation first. It has been proved by engineering theories at home and abroad that it is not only one of the new, energy-saving and environmental protection pipes with good comprehensive function of water supply, but also a very competitive water supply pipe, which will play an unparalleled role in improving water quality and improving people's living standard.Sandbay,Application fields: chemical industry, construction industry.Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, we can give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been used for nearly years. The ninetieth generation of the last century plans to replace it. Because the oak material is not modern enough, the container leaks due to corrosion days after it is replaced with stainless steel.Pipeline direct drinking water has developed rapidly. With the development of national economy, pipeline direct drinking water has developed rapidly in domestic cities such as Beijing, Shenzhen, Shanghai and Chongqing, and economically developed medium-sized cities have also actively planned to catch up. In direct drinking water, stainless steel pipe system is undoubtedly second to none. At present, domestic high-grade hotels and public places have been equipped or are equipped with direct drinking water pipes.

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.The cold working process performance and cold forming performance are much better than that of ferritic stainless steel.AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.Respect for customers,Household worries.First of all, let's understand what stainless steel is. Generally speaking, steel that will not rust is called stainless steel, but in an academic sense, steel resistant to weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid resistant steel. In practical application, while the steel resistant to chemical medium is called acid resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about %, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self passivation film) on the steel surface, which can prevent further corrosion of the steel matrix. In addition to chromium, the commonly used alloy elements include nickel, molybdenum, titanium, niobium, nitrogen, etc., so as to meet the requirements of various uses on the microstructure and properties of stainless steel.After that, the second widely used steel is mainly used in food industry, pharmaceutical industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than stainless steel pipe, it is also used as & ldquo; marine steel & rdquo;. SS is usually used in nuclear fuel recovery devices. Grade stainless steel Steel pipes usually also meet this application level.
