Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel belongs to carbon manganese steel, the content of carbon is about 0.16%, and the yield point is equal to 343MPa (strength grade is 343MPa). 16Mn steel alloy content is less, good weldability, welding generally without preheating. But because the 16Mn steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat.
Q:How to descaling galvanized steel pipe?
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
Q:Seamless steel pipe and welded pipe what is the difference?
The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
Q:How to make the magnetic steel, can be like a magnet?
Of course, not all materials can be magnetized, austenitic stainless steel will not do.
Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
Differ,Thermal expansion seamless steel tube is what we often call "thermal expansion tube", the density is relatively low, but a strong contraction of the steel pipe, (seamless steel pipe) can be referred to as "heat expansion.". A finishing rolling process for pipe rolling by using oblique rolling or drawing method to enlarge pipe diameter. In a relatively short period of time, the outer diameter of the steel pipe becomes larger, and the seamless tube with nonstandard and special type can be produced, and the cost is lower and the production efficiency is high, which is the development trend of the international rolling tube field at present.
Q:Are metal spiral tubes the same as metal bellows?
The corrugated pipe is extruded by the extruder, the winding pipe is wound in a circle, and the prestressed metal corrugated pipe is a reserved channel.
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel pipe mainly because of anti-interference and electrical connectivity, to prevent other strong magnetic strong signal interference weak signal, while in the electrical connection, galvanized steel pipe can be directly connected to the bridge.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
Q:Is it good to buy a simple wardrobe or a steel pipe?
Natural nobility, if the quality and the degree of firmness, is the simple steel cloth cabinet is the best. However, because the texture of wood wardrobe, solid wood wood may be used after deformation.
