Application fields: chemical industry, construction industry.The bearing capacity of decorative stainless steel pipe ice load is the main control load of offshore platform in severe cold area, which has high requirements for the shear bearing capacity of jacket leg of 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,Vilar de Andorinho904L stainless steel plate,Vilar de AndorinhoStainless steel anode tube,Vilar de Andorinho405 stainless steel plate, 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, 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. A compound forming process of double-layer stainless steel pipe for primary circuit main pipeline of station is designed, which solves the problem of limited length of finished products in traditional forging or casting process, and meets the special requirements of complex working environment on pipeline performance. The three roll cross rolling forming process of double-layer casing with outer layer -n austenitic heat-resistant stainless steel and inner layer cr-ni martensitic heat-resistant stainless steel was simulated and optimized by using DEFORM-D finite element simulation software. The internal and external deformation, stress-strain field and temperature field of double-layer stainless steel pipe were analyzed, and the optimal deformation parameter combination was obtained by orthogonal test. The simulation results show that in the process of three roll cross rolling, the large values of equivalent stress, equivalent strain and temperature are concentrated in the area between the outer tube and the roll, and the overall performance parameters of the outer tube are greater than those of the inner tube. The range analysis and variance analysis of orthogonal design test show that the optimal deformation parameter is rough rolling temperature deg; C. Feed angle & deg;, Roll speed: rmin. Objective to improve the existing connection mode of the braking system pipe system of railway freight cars, and accurately shape the end of the stainless steel pipe, so as to obtain the forged joint with better mechanical properties. According to the connection mode of the original pipe system and the plastic forming characteristics of steel pipe, a multi-step upsetting and extrusion process for the end of stainless steel pipe is proposed.

It is suitable for stainless steel easy to produce residual austenite.Model & mdash; Add a small amount of sulfur and phosphorus to make it easier to cut.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.

. Raw material problem of stainless steel pipe. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing, which affects BQ performance. BQ with high hardness is relatively good.Today, Xiaobian can help you. If you want to choose high-quality stainless steel pipe water supply pipe, you can choose this: choose the material of stainless steel pipe water supply pipe.The continuous casting of stainless steel pipe fittings is generally matched with the refining furnace, which has strict requirements on the chemical composition and temperature of molten steel; In order to prevent secondary oxidation of molten steel, non oxidation protection pouring is required during continuous casting production; Strict requirements for refractory materials such as ladle, tundish, nozzle and submerged nozzle.investment,Therefore, the field with high utilization rate of stainless steel with high competitiveness and comprehensive quality will also be an important part of the plan.Raw materials -- strip splitting -- welded pipe making -- heat treatment -- Correction -- straightening -- end repair -- pickling -- Hydrostatic Test -- Inspection (spray printing) - packaging -- delivery (warehousing) (pipes for welded pipe industrial piping).Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.
