Q:Classification, advantages and disadvantages of stainless steel welding
Metal gas shielded arc welding.It belongs to the gas protection welding, also is a kind of arc welding, that is, in the protection of gas, welding rod arc melting. Metal gas welding can be used in steel, non alloy steel, low-alloy steel and high alloy, etc. these materials are widely used. But one thing, its protective gas must be an active gas, such as carbon dioxide or a mixture of gases. The only drawback is that if the outdoor welding, then the workpiece can not be damp, otherwise it will affect the protection of gas protection effect.
Q:Are stainless steel tubes and galvanized steel tubes the same?
It's quite different!The stainless steel pipe itself is made of stainless steel, and galvanized steel pipe is coated with zinc on the surface of the carbon steel tube
Q:304 stainless steel, welded to seamless difference in what place?
The strength of the pipeline depends on the alloy composition, which contains the same alloy and the same heat treatment of stainless steel seamless pipe and welded stainless steel pipes essentially consistent strength.After the tensile test and three-dimensional vibration test, welded stainless steel pipes tearing almost all occurred in the region far away from the welding point or local heating. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, ASME (American Society of Mechanical Engineers) that welded stainless steel pipes can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today.The provisions of ASME 100% completely under permit pressure through ultrasonic testing of welded stainless steel pipe. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current testing of welded stainless steel tube for eddy current testing is subject to legal procedures and licensed institutions. TRENT's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
Q:Does stainless steel pipe belong to hardware?
Belong to. Hardware: refers to gold, silver, copper, iron, tin, five metal materials called. Stainless steel pipe is a kind of hollow long strip round steel.
Q:Why is the outer diameter of 1 inch galvanized pipe 33.7? And the outer diameter of one inch stainless steel pipe is 25.4
Some 25.4 such outer threads, is the imperial Whitworth Thread and American Standard unified thread, single head wire estimate.
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
High temperature resistance is also good, the general use of temperature limit is less than 650 degrees centigrade. 304 stainless steel has excellent stainless steel corrosion resistance and better intergranular corrosion resistance. Delta 2 indicates wall thickness of 2 mm
Q:What's the difference between stainless steel pipe or stainless steel composite pipe?
The stainless steel composite pipe is iron pipe. The outside is plated with stainless steel. It is heavy, but it is easy to rust for a long time,
Q:What kind of welding machine is used for welding thin stainless steel plate and stainless steel square tube?
1 mm thick enough, basically argon arc welding machine can, 0.2 thick stainless steel plate welding is not good ah, how have three or four points it can be positive or negative, only a few joints only, mainly to see the technology myself you, not what, the polishing wheel is on the line let's do it, you can buy a good quality of argon arc welding machine, the high price of the arc is stable
Q:Stainless steel welded pipe or seamless pipe expensive?
From the brand can understand: domestic grade Cr smaller numbers are more expensive, the sum of Cr after the larger the number the more expensive, more expensive Cr symbols and so on. Foreign steel also has some rules: such as the stainless steel, the same series of numbers of bigger, longer, more expensive and more letters.
Q:Stainless steel heating oven tube after treatment is heating blue will not be red?
Unless they are not stainless steel, or they control the temperature of the heating tube, the continuous heating will be red, after all, the material has not changed. If the outside of the heating tube is ceramic, it won't be red.
