Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
Seamless steel pipe specifications are: outer diameter, wall thickness, material. Three of these reflect its main features.Welding pipe specifications are: nominal diameter (internal diameter), galvanized or non plated
Q:Fastener type steel pipe scaffold steel pipe wall thickness
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm. The standards in Shanghai are in line with national standards and 3.25mm can be used.Shelf tubes commonly used specifications, sizes are generally 48.3x3.0, 48.3x3.25, 48.3x3.5.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
Including galvanized steel pipe, but galvanized steel pipe is generally used for plumbing professional, electrical professional generally only civil air defense or high anti-corrosion requirements of the region;
Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:Are metal spiral tubes the same as metal bellows?
The spiral pipe is mainly used in the pipeline of petroleum and natural gas, and its specifications are indicated by outer diameter * wall thickness.
Q:What does cathodic protection of steel tubes mean?
Applied current: a macro cell consisting of a protected metal piece and an insoluble auxiliary component. The negative electrode of the battery is connected to the metal to be protected. The power supplies the electrons so that the metal is not corroded by missing points.
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Q:How much is the wall thickness standard of building 48?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:What are the advantages of PVC pipe and galvanized steel pipe?
This is different in different fields, in fact, the combination of PVC pipe and galvanized steel pipe becomes plastic steel pipe.The steel plastic pipe is in the internal and external combined with a layer of plastic pipe material and obtained a pipe, it has high mechanical strength, the steel pipe has the advantages of high impact resistance, and corrosion resistance of plastic material, has the advantages of high and low grade health fluid resistance and scaling.The steel pipe used by our company is produced by Benxi Steel, which is well known both at home and abroad. It has the advantages of low phosphorus, low sulfur and high mechanical performance. It can meet the requirements of users.
Q:What are the main aspects of precision steel tubes?
Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling.
