Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
The pile reinforcement cage construction characteristics: in general application of the reinforcement cage can be used when not required manual assembling reinforcement cage, such as deep or large pile diameter should be used for solid and solid mechanism of reinforcement cage better (by reinforcing cage seam welder production) to meet Zhuang Jishi high technology requirements, enhance the stability of pile foundation.
Q:How do you solder purple copper plate and steel tube?
When the copper and copper tube size is too large, argon welder welding, DC argon arc welding machine, of course, when DC argon arc welding welding belongs to welding, argon arc welding of brass with Wei Odin 204S welding, the argon arc welding wire for gas welding is not brass wire, this concept must be clear, the wire diameter of 2 80-120A, welding current parameters, if the copper thickness is relatively thick, with a red copper welding after welding preheating in advance.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:What is lined pipe?
There are inner pipe jacket, such as day, tube, etc.; there are outside the pipe painted, such as large-diameter water pipes. An internally coated steel pipe for corrosive medium fluids replaces the expensive stainless steel pipe.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
With this kind of steel manufacturing products, usually by heat treatment (normalizing and tempering); parts made before use, usually need to go through refining or chemical surface treatment (carburizing and nitriding), surface quenching or high-frequency quenching treatment. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use of different, such steel can be roughly divided into carburizing, quenching and tempering and nitriding steel three.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Outside diameter 89, most are cold drawn, more than 89 hot rolling.
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
purpose2.1 seamless tubes are widely used. General purpose seamless tubes are rolled from plain carbon structural steel, low-alloy structural steel or alloy structural steel, with the most output and are used primarily as pipes or structural parts for conveying fluids2.2, divided into three kinds according to the supply of different uses: the supply of a, according to the chemical composition and mechanical properties; the supply of B, according to the mechanical properties; the supply of C, according to the hydraulic pressure test. According to a, the B class steel supply, such as for under fluid pressure, but also to the pressure test.2.3. Seamless tubes for special purposes include seamless tubes for boilers, seamless tubes for geology, and seamless pipes for petroleum use
Q:What's the gate number of the precision steel pipe?
This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel weldability is very good, general use TIG with J50 welding wire, hand arc welding with J506, J507 and other welding rod
