Q:304L stainless steel pipe can withstand 0.1MPA?
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
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.
Q:Why can't stainless steel tubes be cut with acetylene?
That is because the iron element in the high temperature, if the above 99,6% will occur on the oxygen oxidation phenomenon is very strong, because of the heat transfer cycle, in order to make the cutting to continue uninterrupted, continuous heating it when cutting calories.
Q:What factory uses industrial stainless steel tube to be more?
The automotive industry also has a lot of demand for stainless steel pipes. The main use of stainless steel is the exhaust system, which accounts for more than 1/2 of the total amount of stainless steel in the automobile, and 80% of the ferritic stainless steel. The exhaust gas from the automobile engine flows through the exhaust manifold, front pipe, hose, converter, and central pipe and finally flows out of the muffler. Commonly used in the exhaust system are 409L, 436L and so on. Automobile muffler mainly uses stainless steel pipe. According to estimates, the use of stainless steel pipes in the car accounted for the entire downstream of the stainless steel pipe about 1.5% of the amount, while the use of stainless steel seamless tubes and welded pipe ratio of about 2:1.
Q:About stainless steel welding deformation
For welding of grade 304 stainless steel, the current can be adjusted a little, not preheating, to prevent deformation after welding, the welding sequence should pay attention to, such as left -- right -- in the welding line, avoid welding head, to prevent warping.
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Austenitic stainless steel is the stainless steel with austenite structure at normal temperature. When the steel containing Cr is about 18%, Ni, 8%~25% and C is about 0.1%, it has a stable austenite structure. Austenitic chromium nickel stainless steel includes the famous 18Cr-8Ni steel, and on this basis, increasing the content of Cr, Ni, and adding Mo, Cu, Si, Nb, Ti and other elements developed by the high Cr-Ni series steel. Non magnetic austenitic stainless steel with high toughness and plasticity, but the intensity is low, not through the phase change to strengthen, can only be strengthened by cold working, such as adding S, Ca, Se, Te and other elements, it has good machinability. Good comprehensive performance, corrosion resistant variety of media.To prevent intergranular corrosion, this kind of stainless steel is usually low carbon or ultra low carbon.
Q:Where is the difference between seamless steel pipe or welded pipe?
1., the appearance of seamless steel pipe and welded pipe difference in the welded pipe wall welded tendons, and seamless No.2. seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:How can the stainless steel tube eliminate stress?
After heating 500 degrees, placed at room temperature or placed at room temperature for more than 2 years
Q:The difference between galvanized steel pipe and stainless steel pipe
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:Stainless steel pipe pickling ratio
Usage: apply proper amount of this product onto the surface of stainless steel to be processed, the thickness of 1~2 mm, 5-30 minutes or longer (by dirt, sheet materials and processing requirements), process the best brush a few times, the surface oxide skin, rust completely clean, with water (lime water or salt water better) rinse, avoid rust.
