Production mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. 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.Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transmission pipelines such as petroleum, chemical industry, medical treatment, food, light industry,MazatlanPrecision stainless steel belt manufacturer, mechanical instruments and mechanical structural parts. In addition, when the bending and torsional strength are the same, the weight is relatively light. It provides L stainless steel pipe, s stainless steel pipe and L stainless steel pipe for a long time. It is an old brand of with advantages in price and guaranteed quality It is also widely used in manufacturing mechanical parts and engineering structures. It is also commonly used as furniture, kitchenware, etc.Mazatlan, which is intuitive and convenient. However it is not suitable for steel pipes with hard or thin steel.Oranjestad,Assembly: the sealing ring shall be correctly installed in the U-groove of the pipe fitting, put the pipe into the socket of the pipe fitting and wait for crimping.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.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 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, 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, 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.

The experimental ice load of concrete decorated stainless steel pipe is the highest in the cold areaStainless steel pipe will not rust, but it is relatively not easy to rust. It will rust in a specific environment. It will rust if placed in seawater or acid-base environment. Even in the air, it will be corroded and oxidized slowly, but it will take a long time. In general, stainless steel pipes will not rust. However, if the stainless steel pipe is used or maintained improperly, the stainless steel pipe may rust. When we see rust spots on the steel surface, we can quickly confirm that it is a sign of rust. Why does stainless steel pipe rust? First of all, let's understand the structure of stainless steel pipe: stainless steel pipe is a crystal solid composed of atoms similar to a piece of toys. In addition to iron, it also contains its metal components, such as chromium, nickel, titanium, etc. Chromium and nickel have anti rust function. It forms a protective film - passive film to prevent stainless steel pipe from rusting. Generally, as long as the film is not damaged, broken or contaminated by impurities, the stainless steel pipe will not rust. However, if the blunt film is damaged due to improper use or maintenance, the stainless steel pipe will rust.According to the purpose, it can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure chemical fertilizer pipe, petroleum cracking pipe) and marine pipe.Standard requirements,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.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, stainless steel has become one of the cost-effective materials selected by architects. Stainless steel integrates performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.Duplex stainless steel product description: This stainless steel has good corrosion resistance in urea carbamate solution and high stress corrosion cracking resistance in chloride environment. At the same time, the duplex stainless steel has excellent mechanical properties and can be used in plant construction with high safety requirements.
