Q:Why can stainless steel pipes be welded by argon arc welding?
Argon protection can isolate the harmful effects of oxygen, nitrogen and hydrogen on the arc and molten pool in the air, and reduce the burning loss of alloy elements, so as to obtain compact, no spatter and high quality welded joints;
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Stainless steel is usually classified according to the organization of the matrix, as follows:The ferritic stainless steel (200 and 400) the chromium content in 15%~30%, with a body centered cubic crystal structure. This kind of steel does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb and other elements, this kind of steel has high heat conductivity, low expansion coefficient, good oxidation resistance and anti stress excellent characteristics of stress corrosion, used formanufacturingthecorrosionresistanceofthe atmosphere, water vapor, waterandoxidizing parts. Ferritic stainless steel prices are relatively low and stable, and has many unique characteristics and advantages, it has been proved that in many of the original that can only use austenitic stainless steel (300) application of ferritic stainless steel is a very excellent substitute materials, ferritic stainless steel containing nickel, the main elements of Cr (>10%) and iron, chromium stainless steel special corrosion resistant elements, its price is relatively stable.. Chromium 12% ~ 30%. Its corrosion resistance and toughness increase with the increase of chromium content, and the weldability is excellent.
Q:What's the easiest way to distinguish between stainless steel 202 and 304?
They all belong to the austenitic stainless steel, 202 with Mn and N to replace part of nickel, so as to obtain the mechanical properties and good corrosion resistance, is a new type of stainless steel nickel, his strength at room temperature is higher than 304, there are no good oxidation resistance and magnetic strength in medium temperature below 800 degrees. Potions don't fly
Q:Disadvantages of stainless steel tubes
Aluminum plastic composite pipe is a kind of pipe material that is more popular at present. Because of its light weight, durability and convenient construction, it is more suitable to be used in home decoration. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and cold contraction, it will cause the wall of the pipe to be dislocated so as to cause leakage.
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: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:Difference between stainless steel and steel pipe
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).
Q:What kind of welding machine is used for welding thin stainless steel plate and stainless steel square tube?
But I've already attached a ban on reverse welding (the reverse side is a square tube frame)3. I want it to look good after welding.I was just 4. when reading practice a week of welding, can actually be said to have no understanding of welding after graduation, occasionally with ordinary welding iron will often appear in the weld the warning signs, the other is capable person, not a child, he should be responsible for his behavior. Irrigation can not go fishing? We must also be jointly and severally liable for an accident
Q:How can galvanized steel pipe to be connected with stainless steel pipe?
The method of non direct fusion is adopted, such as blue, silk head and movable joint.
Q:Stainless steel tube, also known as why tube
Use can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc.
