Q:304L stainless steel pipe can withstand 0.1MPA?
304L stainless steel pipe can withstand 0.1MPAThe pipe can be able to withstand the pressure to see the size, there is the stainless steel seamless pipe pressure is stronger than that of stainless steel pipe joints. 0.1Mpa=10 kg pressure.
Q:Why is stainless steel magnetic?
304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. Like a lot of steel strips, the product is made up of 103 tubes, without obvious magnetic induction, producing 9.5 tubes. Due to the large deformation of the Ling bend, the magnetic sense is obvious, and the square tube produced by the utility model has larger deformation than the round tube, especially the folding part, the deformation is more intense, and the magnetism is more obvious. In order to completely eliminate the magnetic properties of the 304 steel caused by the above reasons, the stable austenite structure can be recovered by the solution treatment at high temperature so as to eliminate the magnetism. In particular, magnetic because it causes 304 stainless steel, and other materials such as stainless steel, carbon steel, magnetic 430 is not the same level, that is to say the magnetic steel 304 always showed a weak magnetic.
Q:Why can stainless steel pipes be welded by argon arc welding?
Argon arc welding arc welding, convenient operation and observation; electrode loss is small, easy to maintain the arc length, welding flux free, coating layer, so it is easy to realize mechanization and automation; argon arc welding welding can almost all metals, especially some refractory metal, oxidizable metals, such as magnesium, titanium, molybdenum zirconium and aluminum and its alloys; by the welding location restrictions, can be used for all position welding.
Q:What factory uses industrial stainless steel tube to be more?
For equipment manufacturing and maintenance, etc., the annual consumption of stainless steel pipe more than 20000 tons. Such industries mainly use sanitary or antibacterial grade stainless steel tube.
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:Comparison of ring type connection and argon arc welding of stainless steel pipe
Characteristics of argon arc welding of stainless steel pipe:1. Permanent structure, reliable quality;2. Reduce the number of parts used;3. The construction technology is relatively complicated.
Q:Stainless steel pipe specification 25*2 what does it mean?
Phi 25*2 indicates that the outer diameter is 25mm and the wall thickness is 2mm. This is a small tube
Q:What brand of stainless steel pipe cutting machine is good?
That choose the cutting way, to me the tool pipe cutting manner is also a very good method, small caliber selection automatic instrument lathe, large caliber SOONFAN anti vehicle type cut pipe (pipe does not turn the rotary knife type), of course, saw blade, saw blade, laser, plasma and other methods can be used, for example to decide according to their own conditions for pipe cutting.
Q:What is the welding of stainless steel?
Sheet argon arc welding greater than 10mm by hand welding or gas shielded welding
Q:How can stainless steel and copper pipe be welded?
Used to burn the brass pipe welding copper tube of copper which is often used for the installation and maintenance of brass stainless steel is rarely used because there are few people who will burn
