Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Butt fastener: used for connecting two steel pipe jointsThin-walled stainless steel pipe, the national standard consists of three parts, respectively on the thin stainless steel pipe connection, the sealing ring of raw materials of various specifications of O type thin wall stainless steel pipe diameter and wall thickness of pipe and rubber have clear requirements, in order to ensure the quality of the whole pipeline, pipeline safety and guarantee system durability. The connection mode is clamp type and ring type.
Q:How to identify stainless steel pipe and steel pipe?
The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
In general, steel is divided into two groups according to their chemical composition: carbon steel and alloy steel;(1): carbon steel low carbon steel (C = 0.25%); carbon steel (0.25% < C < 0.60%); high carbon steel (C = 0.60%)(2): alloy steel, low alloy steel (alloy is less than or equal to 5%); in steel (5% < < 10% alloy; high alloy steel (alloy) = 10%)Carbon seamless steel tubes are mostly pipes for mechanical engineering structures and pipes for conveying fluids.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
The straight seam welding is relative to the spiral welding and the T-shaped welding, and so on.
Q:What is the outer diameter of the steel tube?
The outer diameter refers to the maximum diameter including the thickness of the steel tube, the inner diameter is the length of the hollow part inside, and the outer diameter minus the inside diameter is the thickness of the steel pipe
Q:RC is it welded steel pipe or galvanized steel pipe?
Common pipelines in construction are as follows:SC: welded steel pipeTC: wire tubes, thin steel tubesPC: rigid plastic pipesCT: cable trayCP: metal hoseSR: steel grooveRC: water gas pipe
Q:Can the KBG25 steel tube hold 4 six types of cables?
Over five types of cables, the outer cross section is about 24 square millimeters, over six types of network cable for the outer cross section of about 35 square millimeters, so 35*4/490=28.57%, far more than 20%. Therefore, according to the norm, only 3 super six categories can be worn. If the distance is short and the joint is not enough, it can be laid like this, but it does not conform to the construction standard
Q:Does the seamless steel pipe need rust removal?
The use of solvent, emulsion cleaning steel surface, in order to achieve the removal of oil, grease, dust, lubricants and other similar organic compounds, but it can not remove rust, scale, welding of steel surface, so the production in anti-corrosion only as an auxiliary means.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
The difference is: 20# ordinary steel seamless steel pipe. 20G is the type of steel for high pressure boiler tubes.
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.
