Q:What is the difference between seamless steel pipe and welded pipe?
The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
Q:Material of welded steel pipe
GB/T14980-1994 (large diameter welded pipe for low pressure fluid delivery). Mainly used to transport water, sewage, gas, air, heating, steam and other low-pressure fluid and other uses. Its representative material is Q235 grade a steel.GB/T12770-1991 (stainless steel welded pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotels and restaurants, decorations and other mechanical parts and structures. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
See the galvanized pipe and seamless steel pipe steel that differences in how if the difference is too large then the steel used for two kinds of materials for welding requirements is not the same, do not recommend direct welding, low pressure can be used in high voltage wire, welding on both sides of the same material flange with flange connection.
Q:Seamless steel pipe and welded pipe what is the difference?
Identification method: see the inside of the pipe, because the external, will deal with the welded pipe is inside a gap, you can see some, some, is not easy to see, you can slowly by hand touch, or see the specifications are relatively thin, welded pipe
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
That is, according to the production process of different classification, different from hot rolling (expansion) pipe. In the process of expanding the tube or raw material tube, it is processed by multiple cold drawing, usually on single chain or double chain cold drawn machine of 0.5 ~ 100T. Cold rolled steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube, machining pipe, thick wall pipe, small diameter and cold drawn steel tube also includes other tubes, carbon thin-walled steel, alloy thin-walled steel pipe, stainless steel pipe, special-shaped wall steel pipe. The outside diameter of cold drawn steel tube wall thickness to 6mm, to 0.25mm, to 5mm diameter thin-walled tube wall thickness is less than 0.25mm in size, accuracy and surface quality were significantly better than the hot (expanding) tube, but by the process control, its diameter and length are limited.
Q:What are the uses of seamless steel tubes?
Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, such as rolling bearing ring, Jack and so on, has been widely used in steel pipe manufacturing.
Q:What's the difference between steel pipe and pipe fittings?
Pipe fittings: parts that connect pipes to pipes. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange pipe fittings and welding pipe fittings four kinds. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.
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:Are galvanized steel tubes the same as degaussing steel tubes?
Degaussing steel tubeThe degaussing method specifies the following demagnetization in the established process document
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
