Q:What's the difference between stainless steel decorative pipes and polished stainless steel pipes?
Polished stainless steel pipe is different from stainless steel decorative tube, generally speaking, the material is better. Yes, the steel tube just appeared is a bit rough and not smooth enough, so it needs polishing to make it appear smooth. Mostly Austrian stainless steel, nickel, corrosion resistance, but the price is expensive, mainly for industrial and outdoor decoration.
Q:How much is one ton of stainless steel pipe?
First of all, to determine the use of your stainless steel pipe, and now mainly with 304 stainless steel and 316L stainless steel,304 moderate price, good rust resistance, suitable for daily home decoration.
Q:How much more expensive is 304 stainless steel than 201?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. The common marking methods in the market are 06Cr19Ni10, SUS304, in which 06Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.
Q:What does "stainless steel pipe 201304" mean?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.
Q:How can the stainless steel tube eliminate stress?
Or artificial stress, method: stresses both ends of the steel pipe fixed by the mold, through high-frequency shocks, so that the internal stress relief of the steel pipe
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: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:Stainless steel pipe pickling ratio
Usage: used for contaminant removal of various types of stainless steel parts, sheet metal surface and its equipment rust, oxide skin, after welding of yellow blue black spot welding, a silver white metal surface cleaning, and surface passivation, corrosion resistance of stainless steel.
Q:What are the connecting methods of stainless steel pipes for indoor water pipes?
Card type features: easy to install, connecting the external pipe, the internal rubber ring is evenly compressed into hexagonal. Scope of application: cold water system, pipe direct drinking water system, and more suitable for pipe installation. The utility model has the advantages that the connection is simple and convenient, the working hours are short, and the cost is moderate. Drawback is the single application, the maintenance of trouble, both the pipe sealing ring in aging and need to be replaced more trouble, because the connection was stuck, replacement is the need to both ends of the pipe to replace the sawing.
Q:How can I clean the stainless steel tube?
1, cleaning stainless steel gently method is simply to use hot water and clean soft cloth to wipe the surface, and then use dry metal with other soft cloth, to prevent water stains thoroughly.2, if ordinary water leaves some dirt or grease, you can add a mild detergent water.
