Q:Fastener type steel pipe scaffold steel pipe wall thickness
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm. The standards in Shanghai are in line with national standards and 3.25mm can be used.Shelf tubes commonly used specifications, sizes are generally 48.3x3.0, 48.3x3.25, 48.3x3.5.
Q:Will the steel tube dance?
The steel tube dance tube has a rotating steel tube and a fixed steel tube, so that different types of steel pipe can be chosen according to the type of pipe dance performed by the dancer.
Q:Where is the difference between seamless steel pipe and welded pipe
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:How are steel tubes represented?
If you speak of steel pipe, if it is water. Gas transmission pipe, then it is said: nominal diameter refers to the inner diameter. The units are millimeters or inches. [for example, water pipes with phi 25. It means that the nominal diameter (diameter) is 25mm (or an inch) steel pipe.
Q:Seamless steel tube with the tube with what is the difference?
Of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good, pay attention to oh!!
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
15CrMo is a steel Pearlite Heat-resistant steel, has high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloy elements in steel, the tendency of hardening of steel is obvious, and the weldability is poor.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Seamless pipe hot rolling, cold rolling, cold drawn three kinds. Among them, the amount of hot rolling, the largest quantity, the price is relatively cheap. Precision, roughness, mechanical properties, cold drawn and cold rolled are better. Of course, the specific use of your requirements, not expensive
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
The general production of hot-rolled seamless steel pipe in the automatic tube rolling mill. Solid billet after inspection and clearance of surface defects, cut into required length, in the tube hole end surface of centering, then sent to a heating furnace, in punch in punch. While continuing to rotate and advance, in the roll and immediate action, tube gradually form a cavity, called capillary. Sent to the automatic tube rolling mill on rolling. Finally after all the entire thickness, sizing machine sizing, achieve specifications. Using continuous pipe mill production of hot-rolled seamless steel tube is advanced.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing must be used or combined method of cold rolling. Usually in two roller mill, rolling ring groove tapered plug pipe in variable cross section circular slot and the composition. Drawing is usually in single or double 0.100T chain drawbench.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller die hole extrusion. This method can produce smaller diameter steel pipe
Q:What does GALV mean in a steel tube?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:What type of steel pipe for security windows?
General anti-theft window through the round tube is 3 cm square tube, 22.5 mm diameter round tube, also can use all square tube to do, if you want to median 304, the pipe is estimated more expensive, the market to do the price in 60 to 110 range. As for plastic steel, Anhui conch brand, the price of 180 this way. Aluminum alloy 110 to 230 specific look what material?!
