The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.

For the manual clamping tool, the upper and lower jaw are fixed modules, and the pressure is set to output a constant pressure of 50MPa. The detection standard is to observe the seam of the upper and lower jaw and press it once or twice.

.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 a total of 18 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 19 specimens in 5 groups were compared, and the effects of different void ratio,SUS440C stainless steel plate, 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 21-2n austenitic heat-resistant stainless steel and inner layer 12cr-12ni martensitic heat-resistant stainless steel was simulated and optimized by using DEFORM-3D finite element simulation software. The internal and external deformation, stress-strain field and temperature field of double-layer stainless steel pipe were analyzed, 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 1100 deg; C. Feed angle 8 & deg;, Roll speed: 200rmin. 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, and the forging forming process is analyzed

The national standard thickness of stainless steel pipe mainly depends on the thickness of raw materials and processing technology. The thickness of welded pipe is basically the same as that of raw materials. For seamless pipe, it is slightly thinner than that of raw materials. At present, the stainless steel pipe industry is dominated by large negative difference, mainly for the consideration of cost saving, 0 thickness. It provides all kinds of stainless steel plates, stainless steel coils, stainless steel belts, stainless steel pipes for individuals and enterprises all over the country for a long time, on-site settlement and honest operation. There are offices all over the country for long-term cooperation. Generally there will be 0.91 ~ 1.

.The large electric clamping tool is 220V power supply, and the motor drives the oil cylinder to clamp. The connecting oil pipe and quick connector must not be contaminated otherwise the dirt entering the oil circuit system will affect the normal use of the tool. Connect the main engine and hydraulic cylinder, turn on the power supply first, then tighten the pressure relief valve, wait until the pressure gauge rises to about 45MPa, or the main engine automatically trips, then open the pressure relief valve, turn off the power supply, and remove the tong head after complete pressure relief.

Shop around and choose affordable stainless steel water supply pipes. Comparing the prices of pipes sold by various companies, we should choose carefully and should not buy them. However, which saves the transmission cost, so the price will not be too expensive.

  ·Rotary shaft, press roller, blade, impeller, etc. in high-strength corrosion-resistant environment.

Buttress shall be set at the turning of T-interface pipeline in vertical or horizontal direction. The size of buttress shall be determined through calculation according to pipe diameter, corner, working pressure and other factors.

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.

Allowable depth of straight track: hot rolled and hot-rolled steel pipes with diameter less than or equal to 140mm shall not be greater than 5% of the nominal wall thickness, and the large depth shall not be greater than 0.5mm; cold drawn (rolled) steel pipes shall not be greater than 4% of the nominal wall thickness, and the large depth shall not be greater than 0.3mm.

Fair price.  309— It has better temperature resistance.

The power supply with vertical external characteristics is adopted, and the positive polarity is adopted in DC (the welding wire is connected to the negative pole).

In addition to common scenes in life, stainless steel is also used in some high-end machinery fields, such as food industry, chemistry, medical devices, aircraft exhaust pipes, etc. It can be seen that stainless steel has been widely used in heavy industry, light industry, daily necessities industry, architectural decoration and other industries. Due to the superior performance, the professional L stainless steel pipe, s stainless steel pipe and 904L stainless steel pipe have advanced technology, strict testing, more affordable price and more preferential. Consultation is welcome. The market of stainless steel is destined to be sesame blossom and higher!

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.

plan.In the past few years the United States has imposed anti-dumping and countervailing duties on a variety of steel pipe products exported from China, including ring welded pipe, rectangular pipe, pipeline pipe, welded stainless steel pressure pipe, oil well pipe and seamless steel pipe. These foreign double back pressures have greatly reduced the number of steel pipes exported by China.

Since the beginning of last year, foreign countries have frequently carried out & ldquo; Double inverse & rdquo; This has a great impact on China's stainless steel casting industry. Export is a large part of the development of China's stainless steel industry and occupies a huge market share in its industrial development. In the face of economic downturn and slow development, the development of China's stainless steel industry should constantly improve product quality, Better develop overseas trade and deal with trade protectionism,Stainless steel tape magnetic, combine products with environmental protection, energy resources and cultural environment, and improve the competitiveness of stainless steel products. Only in this way can we achieve an invincible position in foreign trade.
