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, the smaller the shear strength. Combined with the test, 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, 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, the peak acceleration and displacement of the upper deck of the composite offshore platform of concrete filled steel tubular in stainless steel pipe are reduced by % and % respectively. The analysis of ABAQUS finite element and experimental simulation results shows that the error of the two results can be basically within %. Through the simulation analysis of the ultimate bearing capacity of the stainless steel tube in tube concrete-filled steel tubular composite platform and the original offshore platform, 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.Stainless steel, precipitation hardening stainless steel and high alloy with iron content less than % are usually named by patent name or trademark.Alexandroupoli Airport,The cold rolled steel strip has good strength and yield ratio, and the hot rolled steel strip has good ductility and toughness.W = (outer diameter wall thickness) & times; wall thickness & times; . = KGM (weight per meter).Guayaramerin,Model & mdash; High strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach hrc. It belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: C and f (easy to process).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,Alexandroupoli AirportUnit price of 314 stainless steel plate, 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.In order to ensure the appearance quality of continuous casting slab, select appropriate maintenance slag; During continuous casting, the vibration marks formed on the surface of continuous casting slab due to the vibration of mold shall be; Electromagnetic stirring must be used in continuous casting of ferritic stainless steel pipe fittings.

Stainless steel has two classifications: one is divided into chromium stainless steel and chromium nickel stainless steel according to the characteristics of alloy elements; The other is divided into m stainless steel, f stainless steel, a stainless steel and A-F duplex stainless steel according to the microstructure of steel in normalized state.As long as it is a socket connected stainless steel wire, buttress must be set through calculation.The domestic prospect is promising, and there is a large demand for building water supply pipes. According to the 'Ninth Five Year Plan' of construction and the outline of long-term objectives in , the demand for each pipe is ~ km from to , including km of cold and hot water pipes in residential construction areas.
