When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the bottom welding is carried out for the protection of ventilation (see Table ) and the outside is blocked with adhesive cloth.Low temperature processing of stainless steel pipe --- martensite series stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote martensite quenching. It is suitable for stainless steel easy to produce residual austenite.Offenbach,　　≥EL（%）Solution treatment. The main purpose of water quenching after heating the steel to ~ ℃ is to dissolve the carbide in austenite and keep this state to room temperature, so that the corrosion resistance of the steel will be greatly improved. As mentioned above, in order to prevent intergranular corrosion, solid solution treatment is usually used to dissolve CrC in austenite and then cool rapidly. Air cooling can be adopted for parts, and water cooling is generally adopted.Enfield Town,Water preparation, storage, purification, regeneration, seawater desalination and other water industry excellent materials. The demand is about tons.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.When the stainless steel fixed port is welded, it will be difficult to ventilate on both sides of the weld. At this time, how to ensure the argon filling protection on the inner side of the weld has become a difficult problem. For a long time, facing the national high price, the reasonable price and perfect service of all kinds of stainless steel plates, stainless steel coils, stainless steel belts and stainless steel pipes have been recognized by the majority of customers. In the actual construction on site, we use two welding joints The above problems were successfully solved by plugging with water-soluble paper on the side, ventilation from the weld center and sealing with adhesive tape on the outside (see Table ).

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, 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.

At the same time, it can also well ensure the welding quality (in the capacity expansion and reconstruction project of Urumqi petrochemical, we use this method to weld joints and repair joints, with a one-time qualified rate of welding), which is worthy of our use.Stainless steel pipe, which was consumed and used at the end of the s, is a rebirth group emerging in today's pipe range. It has been widely used in the construction of water supply and direct drinking water pipelines. Stainless steel pipe is durable and has been recognized by the engineering community, and relevant parties are starting from reducing wall thickness and money, so as to facilitate further implementation. In order to promote stainless steel pipe, China has started to reduce wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical effect of stainless steel pipe makes the stainless steel pipe lose its application and expand quickly. There are various connection modes of stainless steel pipes. The rare types of pipe fittings include contraction type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and derivative series connection mode combining welding with traditional connection. These connection methods have different application ranges according to their principles, but most of them are convenient, firm and reliable. The sealing ring or gasket materials used for connection are mostly silicone rubber, nitrile rubber and EPDM that meet the requirements of national specifications, due to the glorious history of galvanized steel pipe, all kinds of new plastic pipes and composite pipes have been lost and developed rapidly, but they are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. In direct drinking water, stainless steel pipe system is undoubtedly one of the best. At present, hotels and public places at the international level have been equipped or are equipped with direct drinking water pipelines. In many cases, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm has the characteristics of safety, reliability, sanitation, environmental protection economy and applicability in high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first.

The protection mechanism of stainless steel backing wire + TIG process is that the back weld is protected by the metallurgical reaction of slag produced by welding wire melting and its alloy elements, and the front weld is protected by argon, slag and alloy elements.Quotation sheet,After fine tuning the molten steel temperature in the argon blowing station, it is lifted to the ladle rotary table for continuous casting.The Chinese brand cold rolled non oriented silicon steel strip (sheet) represents: DW + times of iron loss value (at the frequency of Hz, the waveform is sinusoidal and the magnetic induction peak is T per unit weight iron loss value) + times of thickness value. For example, dw- represents cold rolled non oriented silicon steel with iron loss value of W / kg and thickness of .mm. Now the new model is represented as W.There are mechanical chemical and electrochemical methods to remove the scale of stainless steel pipe. Due to the complexity of the composition of the scale of stainless steel pipe, it is not easy to remove the scale on the surface and make the surface highly clear and flat. Generally, the removal of the scale of stainless steel pipe should be carried out in two steps, the first step is pretreatment and the second step is ash removal.Offenbach,In the building water supply pipe system, due to the end of the glorious history of galvanized steel pipe, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some deficiencies in varying degrees, which are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality.
