Q:What is the production process of seamless steel tube?
The delivery status of hot-rolled seamless steel tubes is generally hot-rolled and delivered after heat treatment. Hot rolled seamless steel tube after quality inspection after staff strict hand picked in quality inspection should be carried out after the oil surface, followed by cold drawing experiments, hot rolling process should be carried out after the perforation experiment, if perforated expanding too large to carry out straightening correction. After straightening, the device is sent to the flaw detector by the transfer device to carry out the flaw detection experiment. Finally, the label is attached and the specifications are arranged and placed in the warehouse.
Q:Does seamless steel tube have a bend of 135 degrees?
Other name: 90 degree elbow, right angle bend, love bend, punching elbow, pressing elbow, mechanism bend, welding elbow, etc..Usage: connect two pipes with same nominal diameter or different pipe, make the pipe bend at 90, 45, 180 degrees and various degrees.Bending radius is less than or equal to 1.5 times the diameter of the elbow. It is 1.5 times larger than the pipe diameter and belongs to the elbow
Q:What is lined pipe?
Is the coating of the inside of the pipe, such as pipe conveying sulfuric acid will corrode, corrosion, but soft plastic pipe, buried in the ground to wall thicker, then you can use the liner and characteristics of hard for using steel pipe laying, sheathed in the steel pipe into the thin plastic tube, it can transport the sulfuric acid,
Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness.
Q:What's the difference between round and round tubes?
Round steel is solid and round tubes are hollow
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
However, there are a variety of non GB steel tubes on the market, mainly in the wall thickness, and are thinner than the national standard requirements, you said that thickness may have, but the thinnest only about 2.6mm-2.7mm.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
If your project is a seamless steel pipe, so theoretically, you put the tube with connected is not used.But the actual engineering operation, design drawings will be put on the normal need to improve the requirements of the drawings to the actual requirements, so if is the need of seamless steel pipe, welded pipe in the end so can you see yourself.
Q:What does "HBB" glass steel pipe mean?
The utility model has the advantages of high strength, light weight, no deformation, smoothness of the inner surface, etc.. The friction coefficient is small, the cable is light and smooth, and the cable is not damaged. The weight is only 1/4 of the steel tube, and the 1/10 of the concrete pipe can be moved by one person. The transportation is convenient and the construction is simple and convenient.
Q:How is the steel pipe dance installed at home?
Portable pipe with instructions and CD can be installed, portable steel pipe of a new patent, convenient installation, no restriction site, no drilling, readily removable, adjustable height, stainless steel, solid.
Q:DN150 welded steel tubes one meter multiple
The theoretical weight table of welded steel pipe (Kg) can be checked, and the outer diameter and wall thickness can be measured according to the formula.For example: DN150 welded steel pipe, diameter 165mm, thickness 4.5mm, weight kg per meter.Welded steel pipe theoretical weight (Kg/m) = (165-4.5) * 4.5 * 0.02466=17.81Kg
