Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Major use differentiation:1, seamed tube can withstand the maximum operating pressure is generally less than 20 kg, which is the most secure use. It is generally used in water, gas, compressed air and other low-pressure fluid;2 seamless tube can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.3, there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.4, 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
Q:Are the welded and galvanized tubes the same weight?
The difference is that because zinc has weight, even if the difference is very small, there are also differences,Galvanized pipe weight is basically the same about 1.06 of the welded tube, of course, you can artificially ignored.
Q:Can the KBG25 steel tube hold 4 six types of cables?
The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
D108: refers to the outer diameter of 108mm;4: refers to the wall thickness of 4mm.
Q:Fastener type steel pipe scaffold external parts name
Steel pipeScaffold steel pipe should adopt outer diameter 48mm and wall thickness 3.5mm welded steel pipe, also can use outer diameter 51mm and wall thickness 3.1mm welded steel pipe. For horizontal horizontal rods, the maximum length of steel pipe shall not be greater than 2m; other poles shall not be greater than 6.5m, and the maximum mass of each steel tube shall not exceed 25kg, so as to be suitable for manual handling.
Q:What is the single length of galvanized steel pipe?
Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20G seamless steel tube is a high-pressure boiler tube. In addition to carbon content, 20G seamless steel tubes also have some trace elements that are more suitable for use as boiler pressure vessels. In addition, 20G also focuses on its physical performance. Such as bending, impact and tensile properties. 0G seamless steel tube is a kind of steel strip with hollow section and without seams. A steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
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.
