When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, otherwise it is easy to cause damage and fall off of the water-soluble paper, resulting in loss of argon protection of the inner weld and oxidation, resulting in cutting of the weld junction and re welding, which can not ensure the welding quality and seriously affect the construction period. Therefore, the water-soluble paper should be strictly checked and pasted before welding.The main control load of the platform has high requirements for the shear bearing capacity of the guide leg of the offshore platform. In order to study the factors affecting the shear capacity of the jacket legs of the stainless steel pipe in pipe concrete-filled steel tubular offshore platform, a total of concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material, concrete strength, void ratio and shear span ratio on the shear capacity of concrete-filled steel tubular in pipe. It is found that the shear strength of members increases with the decrease of void ratio and the increase of concrete strength; The larger the shear span ratio, the empirical formula of shear capacity of concrete-filled steel tubular in pipe is proposed, which is analyzed and verified by ABAQUS finite element modeling software. The results show that the simulation is in good agreement with the test results. In order to study the axial compression performance of stainless steel tube concrete conduit leg and the axial compression performance of stainless steel concrete conduit leg, experiments are used to verify the correctness of the finite element model. The load displacement curves of specimens in groups were compared, and the effects of different void ratio, concrete strength, diameter thickness ratio and bone index on the axial compression performance of concrete-filled stainless steel tubular short columns under axial compression were analyzed. The results show that with the increase of concrete strength, the bearing capacity of specimens increases, but the ductility of specimens decreases; With the increase of void ratio and diameter thickness ratio, the bearing capacity of the specimen decreases; The bearing capacity of stainless steel tube concrete can be effectively improved by adding steel bone; Increasing the bone matching index of steel bone can improve the bearing capacity of the specimen. Based on the jacket offshore platform, it is proposed to replace the four hollow steel conduit legs of the original offshore platform with concrete-filled steel tube in stainless steel tube to form a new composite offshore platform with concrete-filled steel tube in stainless steel tube, so as to improve the ice resistance and disaster prevention ability of the offshore platform. The scale test on the offshore platform shows that the composite offshore platform of concrete filled steel tubular in stainless steel pipe (hereinafter referred to as the composite offshore platform) has better anti icing performance than the ordinary jacket offshore platform. Taking push as an example, it can be seen that the stainless steel tube in tube concrete-filled steel tubular composite platform has stronger ultimate bearing capacity. Therefore, the composite offshore platform of concrete-filled steel tube in stainless steel tube is a good new type of jacket offshore platform. Axial compression tests were carried out on austenitic and duplex stainless steel tube concrete short columns. The ultimate load, longitudinal strain and circumferential strain of the short columns under axial compression were measured. The effects of steel tube wall thickness and concrete strength on the bearing performance of the short columns were investigated. Reference was made to the European Code for design of concrete filled steel tubes (Eurocode), American code (ACI -) and Japanese code (aij-cft), China's relevant regulations D --dlt- and CECS calculate the preparation of stainless steel pipe construction, prepare construction scheme and construction schedule scheme, and establish quality standards.Mayagues,: stainless steel wire: it can also be called stainless steel wire, but it is different from stainless steel wire rope.

There is a bright future for domestic substitution for imported stainless steel pipes. Since the s, China has solved the problem of reducing wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical problems of stainless steel pipe make the stainless steel pipe applied and developed rapidly. If a pipeline can be fully applied, localization is indispensable. At present, some domestic have the ability to produce and further develop stainless steel pipes and fittings.According to the production mode, stainless steel pipe is mainly divided into seamless pipe and welded pipe. Seamless steel pipe can be divided into hot-rolled pipe cold-rolled pipe, cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.Promise and keep promise,Martensitic stainless steels typical martensitic stainless steels include Cr ~ Cr and Cr, which have good processing properties. Deep drawing, bending, crimping and welding can be carried out without preheating. Crl does not require preheating before cold deformation, but preheating is required before welding. crlcr is mainly used to make corrosion-resistant structural parts such as steam turbine blades, while crcr is mainly used to make surgical and wear-resistant parts of medical instruments; crl can be used as corrosion-resistant bearings and tools.In the interior decoration project, the proportion of water pipes is very small, whether it is data consumption or price. However, once the water pipes show achievements the results will be very serious. Therefore, it is extremely important to choose water pipes with reliable quality, high volatility convenient maintenance, health and environmental protection. With the development of the national economy and the progress of people's living standards, people's requirements for domestic water pay more and more attention to health and environmental protection. A good water source escort pipeline has become a careful choice. Water pipes are generally experienced in lead pipes & rarr; Copper pipe & rarr; Iron pipe & rarr; Galvanized iron pipe → Plastic pipe & rarr; Development process of stainless steel pipe. It has become a trend in the world to select high-quality stainless steel materials as water supply pipes. The material indicates that in Germany, more than % of residents choose stainless steel water pipes; In Japan, more than % of households in Tokyo have adopted stainless steel water pipes; In Australia, it has begun to change other pipes to stainless steel pipes; In the United States, the water pipes of five-star hotels in Las Vegas are all made of stainless steel. Since the beginning of the st century, due to the progress of living standards, more than % of residents in China need water pipes to meet their needs of high-quality life. Therefore, high-quality stainless steel materials move from tableware to household water pipes. It has become a trend to select high-quality stainless steel pipes in tooling or home decoration projects. Stainless steel water pipes and stainless steel pipe fittings will become an indispensable part of the building materials market in the future. Stainless steel material is a recognized health material that can be implanted. The manufacture of water pipes based on stainless steel has a long history in developed countries. Stainless steel pipe has gradually become a new choice of water supply pipe with the characteristics of safety, sanitation, environmental protection, economy and applicability, and has become the current world trend and development direction. Stainless steel water pipe is called the real green pipe in the st century. With the gradual standardization of stainless steel pipe industry, it can be predicted that the consumption technology and connection technology of stainless steel pipe will also slow down to standardization and become more and more perfect. The development of stainless steel pipe technology will not only create a favorable condition for health, environmental protection and sanitation for national domestic water, but also win a larger market for stainless steel pipe enterprises. Stainless steel pipe entering the construction and decoration market is an attack in the water pipe industry.Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze,MayaguesStainless steel 430 plate, 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.
