When using gb 20 seamless steel pipe, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.
