Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and specifically to a steel pipe outer wall anti-corrosion spraying device. Background Technology

[0002] Steel pipe is a hollow long steel material with a hollow cross section. It is widely used as a pipeline for transporting fluids such as oil, natural gas, water, coal gas, and steam. In addition, steel pipe is lighter in weight while maintaining the same bending and torsional strength. It is also widely used in the manufacture of mechanical parts and engineering structures, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction.

[0003] In existing steel pipe spraying production processes, a rotating mechanism is typically added to improve spraying uniformity, driving the steel pipe to rotate and achieve even paint coverage. However, steel pipes of different specifications exhibit significant quality variations. For heavier steel pipes, a more powerful drive unit is required during spraying to ensure stable rotation, leading to a significant increase in production costs. Therefore, we propose a steel pipe external wall anti-corrosion spraying device to address the aforementioned problems. Utility Model Content
