When using this process, the following key points should be paid attention to: during the welding process, the correct included angle between the welding handle, welding wire and weldment should be maintained. The ideal caster angle of the welding handle nozzle is & deg; & mdash; & deg;, and the included angle between the welding wire and the weldment surface is & deg; & mdash; & deg;; correct the molten pool temperature, change the included angle between the welding handle and weldment, change the welding speed, etc. to change the molten pool temperature, so as to ensure Beautiful weld formation (uniform width no concave, the current shall be slightly larger than that of solid core welding wire convex and other defects) During operation, and the welding handle shall be slightly adjusted to accelerate the separation of molten iron and molten flux coating, so as to facilitate the observation of molten pool and penetration; when filling the welding wire, it shall be sent to places of molten pool and pressed inward slightly to ensure penetration and prevent concave; during welding, the welding wire shall be regularly sent and taken out, and the welding wire shall always be ensured Under the protection of argon to prevent the end of the welding wire from being oxidized and affect the welding quality; pay attention to the welding quality of the arc and arc stop, and the spot weld shall be polished to & deg; the slope shall be gentle, and pay attention to the defects such as arc pit and shrinkage hole during arc stop.In many construction sites,Bailesti316 stainless steel plate, we use this kind of welding for priming, which can effectively ensure its quality and has certain construction difficulties.

Human factors are also one of the causes of product oxidation that some consumers often encounter when using stainless steel products. Some consumers operate improperly in product use and maintenance, especially some stainless steel pipe products used in food and chemical equipment industry. For the artificially generated oxidation of steel products, they should have correct product use knowledge and Reasonable and effective maintenance shall be carried out regularly to reduce oxidation caused by improper use.The content of chromium, molybdenum and nitrogen in local corrosion-resistant duplex stainless steel makes it have strong ability to spot corrosion and interstitial corrosion in oxidizing and acidic solutions.Continuous casting shall be adopted for stainless steel pipe fittings, so as to improve the comprehensive yield, and cooperate with out of furnace refining, which significantly improves the production efficiency, omits the blank opening process and saves a lot of energy consumption.Management Department,Stainless steel seamless steel pipe for fluid transportation (instead of gbt- instead of gbt- instead of gb-)Stainless steel, precipitation hardening stainless steel and high alloy with iron content less than % are usually named by patent name or trademark.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, 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, 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, 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,Bailesti321 stainless steel pipe, and establish quality standards.

Series & mdash; Heat resistant chromium alloy steel.Home page recommendation,Rockwell hardness the Rockwell hardness test of stainless steel pipe is the same as Brinell hardness test. The difference is that it measures the depth of indentation. Rockwell hardness test is widely used at present, and HRC is second only to Brinell hardness Hb in steel pipe standards. Rockwell hardness can be used to measure metal materials from very soft to very hard, which makes up for the disadvantage of Brinell method, It is simpler than Brinell method and can read the hardness value directly from the dial of the hardness machine. However, due to its small indentation, economic, 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,Austenitic stainless steel austenitic stainless steel is developed to overcome the lack of corrosion resistance and brittleness of martensitic stainless steel. The basic composition is crl% and Ni%, which is referred to as - steel for short. Its characteristic is that the carbon content is less than .%, and the single-phase austenite structure is obtained by the combination of Cr and Ni.Since the back is not filled with argon,BailestiStainless steel water pipe 304, its advantages are obvious, mainly for its simplicity and low cost which is suitable for installation on the construction site.
