mThe ice load is the main control load of offshore platform in severe cold area which has high requirements for the shear bearing capacity of the conduit 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， a total of concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material， concrete strength，310S stainless steel pipe void ratio and shear span ratio on the shear capacity of concrete-filled steel tubular in pipe. By studying the failure mode，304 food grade stainless steel pipeHow to play a practical role bearing capacity and local strain relationship of members under different conditions， 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. By comparing the load displacement curves of specimens in groups， 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 are analyzed. The results show that with the increase of concrete strength the bearing capacity of specimens increases，310S stainless steel pipe 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 composite forming process of double-layer stainless steel pipe for primary circuit main pipe of nuclear power plant 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 pipe performance. The three roll cross rolling 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 distribution of double-layer stainless steel pipe were analyzed， The parameter combination of optimal deformation is obtained by designing orthogonal test. The simulation results show that the large values of equivalent stress， equivalent strain and temperature are concentrated in the contact 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. Through range analysis and variance analysis of orthogonal design test， 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，310S 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， stainless steel pipe materials have been widely used in public transportation tools such as buses，304 food grade stainless steel pipeHow to play a practical role subways， high-speed railway vehicles， household cars and so on!

JlStainless steel pipe appeared in Foshan， Guangdong Province in the tenth generation of the last century. With the rapid development of science and technology in recent decades， stainless steel pipe production is all over the country. Stainless steel pipe is more and more widely used. But in fact， most people，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd including many people in the industry， do not know much about the classification and application of stainless steel pipes. Take stainless steel pipe for example.
The pipes for pipe cutting shall be professionally cut by stainless steel. Rotate it for two circles， and then rotate it for two circles until it is cut off. It must not be enough to allow personal strength to be in place at one time to lock the piece to cut off the pipe， otherwise the pipe end will be cut off， and the pipe fittings or rubber rings cannot be inserted; After the pipe above DN is cut the internal and external burrs must be removed with a hand grinder， and an appropriate outer slope opening shall be opened at the same time to avoid damaging the sealing ring.
The above conditions can cause the damage of the protective film on the surface of stainless steel and lead to corrosion.
fProduction process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).
LSeamless stainless steel pipe， also known as stainless steel pipe， is made of steel ingot or solid pipe blank through perforation， and then made by hot rolling cold rolling or cold drawing. The specification of seamless steel pipe is expressed by outer diameter * wall thickness mm. With the implementation of Chinas reform and opening-up policy， the national economy has achieved rapid growth， and a large number of urban houses， public buildings and tourism facilities have been built， which puts forward new requirements for hot water supply and domestic water supply. In particular， people pay more and more attention to the problem of water quality， and the requirements are also increasing. Galvanized steel pipe， a common pipe， will gradually withdraw from the historical stage under the influence of relevant national policies because of its corrosiveness. Plastic pipe， composite pipe and copper pipe have become common pipes in the pipeline system. However， in many cases， stainless steel pipe has more advantages， especially the stainless steel pipe with wall thickness of only . ~ mm， which has the characteristics of safety， reliability， sanitation， environmental protection， energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe， which will play an incomparable role in improving water quality and peoples living standards.

Online consultationuIn order to prevent the occurrence of welding pores， the welding parts must be cleaned if there is rust， oil stain， etc.
VTherefore， there are requirements for the service environment of stainless steel， and it needs to be wiped frequently to remove dust and keep clean and dry.
However， some people will still ask whether our stainless steel pipes can be used as water pipes through online communication or telephone communication.
rPrice of stainless steel pipe with mm diameter: according to the current market situation， the price of stainless steel pipe with mm diameter is yuan per ton.
kQAccording to the steel structure， austenite ferrite ferrite martensite and precipitation hardening note: precipitation hardening (precipitation strengthening): refers to a heat treatment process in which the metal is hardened by the segregation zone of solute atoms in supersaturated solid solution and / or the desolved particles are dispersed in the matrix. For example， austenitic precipitated stainless steel can obtain high strength by precipitation hardening at ~ ℃ or ~ ℃ after solution treatment or cold working. That is， the supersaturated solid solution of some alloys is placed at room temperature or heated to more & amp; gt;& amp; gt;
