Q:The difference between carbon and welded steel tubes
Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
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?
Dimensions of ordinary steel tubes (taken from GB/T 17395-1998)The theory of weight / (kg/m) | wall thickness (2.9 3.0mm: 3.33)
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
Q:Stainless steel tube, also known as why tube?
Production methods can be divided into two categories: seamless pipe and welded pipeSeamless steel pipe can be divided into hot-rolled pipe, cold rolled tube, cold drawn tube and extruded tubeWelded pipe is divided into straight welded pipe and spiral welded pipe and so on
Q:How to distinguish between steel pipe and spiral pipe material?
Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
Q:A333gr6 steel pipe and domestic material of the same?
A333Gr.6 steel is no nickel steel is a kind of fine grain aluminum low temperature toughness of steel, therefore, also called Al killed steel. A333Gr.6 belongs to the United States ANSI and ASTM-SA333 cryogenic steel standards and is used at the lowest impact temperature of -46 degrees celsius. Its temperature, range of use and fracture toughness value are similar to those of domestic 16Mn steel (the minimum usage temperature of 16Mn steel is -40 degrees Celsius).
Q:What materials are used in scaffolding pipes?
Fastener warranty information should be complete, enter the site should be carried out after re sampling technology, performance shall be in accordance with provisions of the "GB15831" steel pipe scaffold fastener, before use should be individually selected, cracks, deformation, bolt slide wire is strictly prohibited.
Q:What are the main aspects of precision steel tubes?
Its inside and outside diameter size can be accurate to less than 0.2mm, and it is widely used in the manufacture of precision machinery parts and engineering structure when the bending resistance and torsion strength are the same. It is also used to produce all kinds of conventional weapons, guns, shells, bearings and so on.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
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.
The company has successively passed ISO9000 quality system, the American Petroleum Institute API, and also earned the environment healthy license, national special equipment manufacturing license.
