Grinding the nozzle of seamless steel pipe: After cutting, the plastic layer of the nozzle should be polished with an angle grinder.
GB/T8162-2008 (Seamless steel pipe for structure). Mainly used for general structure and mechanical structure. Its representative materials (brands): carbon steel 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, 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.
Choose a suitable place and warehouse: The place or warehouse for storing steel should be selected in a clean, clean, well-drained place, away from factories and mines that generate harmful gases or dust. Weeds and all sundries must be eradicated on the site, and the steel must be clean.
In the heat treatment process, the repaired parts must be normalized, and the structural parts that require mechanical properties must be normalized and quenched and tempered to meet the mechanical performance requirements.
Generally, seamless steel pipes are used to transport water, gas, oil and other fluid pipes and to make various structural parts, and their mechanical functions such as tensile strength, yield strength and elongation should be sampled.
