[hot rolled strip / sheet] has the advantages of low hardness, a total of 18 concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material,Stainless steel pipe, 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 19 specimens in 5 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,Stainless steel plastic coated pipe, 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 110 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 push3 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 12% and 240% respectively. The analysis of ABAQUS finite element and experimental simulation results shows that the error of the two results can be basically within 15%. 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,High temperature resistant stainless steel belt, 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 9 austenitic and 9 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 318-9) and Japanese code (aij-cft), China's relevant regulations D 13-51-200dlt5085-1999 and CECS 282012 calculate the preparation of stainless steel pipe construction, prepare construction scheme and construction schedule scheme, and establish quality standards.

(II) The price of steel has been running at a low level. From January 31 to June 2012, the overall performance of the domestic steel market was depressed. With the substantial release of crude steel production capacity, the market supply and demand fell into an imbalance, which has been weak for more than four months. As of June 26, 2013, the steel price index had dropped to 100.48 points, lower than the first 6 points. The prices of eight steel varieties mainly counted by the iron and steel industry association were lower than the first 6 points

.For example, the raw material difference of the three materials, such as 20 and, which are common in the market, is more than 5000 yuan per ton.

Stainless steel tubes can be found everywhere in our daily use. I believe many friends are asking why we have so many stainless steel tube products in our life. Therefore, xincoral Xiaobian will help you better understand the three characteristics of stainless steel tubes.

Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sea water, sea breeze, 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 100 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 16 days after it is replaced with stainless steel.

As we all know, stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances, & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is that stainless steel pipes will also rust. I believe many friends will be surprised! I believe there are many people who don't know how to explain to customers! Next, add n at the end of the brand as spcen. Quenching and tempering code of cold-rolled carbon steel sheet and strip: annealing status is a equivalent to China 08Al (52) deep drawing steel. If it is necessary to ensure non aging property, standard quenching and tempering is s, 1 / 8 hard is 1 / 4, hard is 1 / 2, hard is 1. Surface processing code: dull finish rolling is D, bright finish rolling is B. spcc-sd represents cold-rolled carbon sheet generally used for standard quenching and tempering and matt finish rolling. Another example is spcct-sb It refers to cold-rolled carbon sheet with standard quenching and tempering and bright processing and required to ensure mechanical properties.

(V) the profitability of the steel plant has declined month by month. In the first half of 2013, the metallurgical industry realized a profit of 73.9 billion yuan, a year-on-year increase of 7%, of which the ferrous metal smelting and rolling processing industry realized a profit of 45.4 billion yuan, a year-on-year increase of 27%. From January to may, the profitability of key large and medium-sized iron and steel enterprises was far lower than the overall level of the industry, and showed a downward trend month by month. Although the profit increased by 34%, it was only 2.8 billion yuan, with a profit margin of 0.19%. In May, 86 key large and medium-sized iron and steel enterprises realized a profit of only 500 million yuan, falling month on month for five consecutive months, of which 34 suffered losses, with a loss surface of 40%.

Clamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe, not on the left and right sides of the tong head.
