Q:How to descaling galvanized steel pipe?
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
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 is the diameter of the steel tube DN20?
1, nominal diameter is nominal diameter, or nominal diameter, or nominal size.2, nominal diameter is a variety of pipe and pipe accessories generic caliber. The same nominal diameter of the tube and pipe accessories can connect with each other, with interchangeability. It is not a real sense of the pipe diameter or diameter, although its value is closer with the pipe diameter or equivalent, is a convenient integer for reference only, are not strict with processing size. Nominal diameter is not the outer diameter, nor the inner diameter, but a nominal size similar to the diameter of the ordinary steel pipe. In order to connect the pipe and pipe fittings in a uniform dimension, each nominal diameter corresponds to an outer diameter, and the inner diameter value varies with the thickness.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
High frequency welding uses the skin effect to concentrate the energy of the high frequency current on the surface of the workpiece, and uses the proximity effect to control the position and range of the high frequency current flow path. The speed of the current is very fast, it can in a short period of time will be adjacent to the edge of the steel plate heating, melting, and through the extrusion docking, each has its own advantages, but also each has its own shortcomings. Generally according to specific circumstances, specific analysis of specific choices.
Q:What does "spiral welded steel pipe" DN325*10 mean?
Labeling is wrong: it should be said for 325*10, the diameter of pipe wall thickness of 10, 325;For example, the nominal diameter shall be: DN300.
Q:Seamless steel tube with the tube with what is the difference?
Seamed tube can withstand the maximum 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;
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Classification is not the only way, fastener type steel pipe scaffolding is divided by force, and the latter 2 are classified according to the structure.
Q:Seamless steel pipe is how to do it?
Round tube has some limitations, such as in the plane bending conditions, the tube is better than square and rectangular tube bending strength, and some agricultural machinery skeleton, steel, wood furniture, commonly used square, rectangular tube. According to different purposes, other sections of special-shaped steel pipe are needed.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless 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. Compared with solid steel such as round steel, steel tube is lighter in strength and equal in resistance to bending and torsion. It is an economical cross section steel and is widely used in the manufacture of structural and mechanical parts.
All these steel pipes are suitable for the industries of oil, natural gas,ship building,chemical, environmental protection,boiler, water conservancy, electrical industry,steel structure, building and other related fields.Our company following the principle that ‘customer supemacy, business integrity’We will do our best to supply best products and service to our customers. We expect mutual benefit.
