Q:Stainless steel tube, also known as why tube
Production methods can be divided into two categories: seamless pipe and welded pipeSeamless steel pipe can be divided into hot-rolled pipe, cold rolled tube, cold drawn tube and extruded tubeWelded pipe is divided into straight welded pipe and spiral welded pipe and so on
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:304 stainless steel, welded to seamless difference in what place?
The seamless tube is made by pressing a hole in a stainless steel billet at a temperature of 2200 degrees F. At this high temperature, the tool steel is made soft and spirally shaped from the hole by stamping and drawing. Thus, the wall thickness of the pipeline is uneven and the eccentricity is high. Thus ASTM allows seamless pipe wall thickness ratio of the wall thickness difference of seamed tube. Through the seamed tube cold rolling plate precision (per roll width is 4-5 feet) made. These cold rolled plates usually have a maximum wall thickness of 0.002 inches. The steel plate is cut into a width of PI D, in which D is the outer diameter of the pipe. Tube wall thickness tolerance is very small, and the entire circumference of the wall thickness is very uniform.
Q:Disadvantages of stainless steel tubes
Stainless steel pipe is a kind of more durable pipeline material. But its price is higher, and the construction process requirements are relatively high, but its material strength is hard, the field processing is very difficult. Therefore, in the decoration project, the probability of choice is low.
Q:How thick is the 3 stainless steel tube?
Refers to the stainless steel tube with a wall thickness of 3 mm.
Q:How can the inner walls of stainless steel tubes be polished?
Electropolishing is thrown to the workpiece as anode, insoluble metal poles at the same time as the cathode, immersed into electrolytic cell, with the direct current produced anodic dissolution selectively, so as to achieve the surface brightness increasing effect. Specific can be used to search "what is electrolytic polishing" can understand!
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
Arc welding is the most widely used welding method in industrial production, it is to use the principle of arc discharge (commonly known as arc combustion) the heat generated by the electrode and the work piece and the formation of weld in melting each other after condensation, so as to obtain the solid joint welding process. The scope of application of electric arc welding is very extensive, such as bucket teeth of excavator, loader, bulldozer blade blade plate, screw conveyor, crusher, mixer blade, rail, forging, gear wheel flange, all kinds of mold, slag crusher, ball mill, machine tool equipment etc..
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
1. The pipe is embedded in the pipe, and the ring pressure connection strength is high;2. After the ring is pressed, the inserted part of the pipe and the pipe is a closed ring, which can not generate spiral loosening and strong vibration resistance;3. The sealing material fills the entire seal cavity tightly and the seal is very reliable;4. Easy to install and quick.5. Shrinkage and anti drawing test of ring seal joint
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:What color is stainless steel? What color is stainless steel pipe culture?
You want to draw the stainless steel, or to mirror the drawing, usually gray, mirror is generally bright silver, of course, the color is also there, ah, you need it
