10#Seamless steel pipe instructions
Used in various fields such as automobiles, machinery, construction, boilers, petrochemicals, various chain tubes, electric power, aerospace, ports, ships, bridges, sports, decoration, textile machinery, etc.
10#Seamless Steel Pipe Purchasing Instructions
10# seamless steel pipe delivery status: delivery without heat treatment or heat treatment (annealing, normalizing or high temperature tempering). If the delivery is required to be delivered under heat treatment, it should be indicated in the contract, and if it is not specified, the delivery shall be delivered without heat treatment.
20#Seamless steel pipe technical parameters (such as technical standards of material, process, size, etc.)
Mechanical properties: Tensile strength σb (MPa): ≥410(42) Yield strength σs (MPa): ≥245(25) Elongation δ (%): ≥25 Reduction of area ψ (%): ≥5, hardness : No heat treatment, ≤156HB, sample size: sample size 25mm, 20# seamless steel pipe is made of 20# steel, the strength is slightly higher than 15#, it is rarely quenched and has no temper brittleness. Cold deformation has high plasticity, generally used for bending, rolling, bending and hammer arching, etc.
20# seamless steel pipe performance characteristics
The welding performance of arc welding and contact welding is good, the thickness is small during gas welding, and cracks are easy to occur on the parts with strict requirements or complex shapes. The machinability cold drawn or normalized state is better than the annealed state, and is generally used to manufacture workpieces with low stress and high toughness requirements.
20# Seamless steel pipe instructions (such as use place, working principle, product structure, safe operation instructions, etc.)
Used in various fields such as automobiles, machinery, construction, boilers, petrochemicals, various chain tubes, electric power, aerospace, ports, ships, bridges, sports, decoration, textile machinery, etc.

The role of ground copper rowOnce the power supply line or equipment is seriously overloaded or faulty, the faulty circuit has a great threat to the equipment on the line, which will damage the electrical equipment and damage the normal operation of the power system, therefore, taking measures to protect the equipment on the line and the power line is a prerequisite to ensure the safety of the equipment and equipment. Ground copper row when current or fault occurs, the leakage electricity in the circuit is guided underground to protect the electrical equipment.VIEW MORE
