The production of thick-walled seamless steel pipes through heat treatment processes.

Thick-walled seamless steel pipes can ignite without any issues. However, some may require oil coating. This suggests that the raw materials for round steel might be unstable. Generally, there aren't many issues with round steel from large ironworks, but it can be a different story for smaller ones.

Thick-walled seamless steel pipes are diligent in their corrosion resistance work. The adhesion strength and compressive strength of the hot-dip galvanized layer are good, making it less likely to come off. Although there may be cases of corrosion in hot-dip galvanization, it is considered professionally and with regard to health over a long period. For welding and managing steel of Grade 45, you should apply anti-corrosion agents carefully. You can generally brush on red rust after hot-dip galvanization and then use cold zinc spray to penetrate, effectively maintaining the surface of the zinc film on the Grade 45 steel pipe, preventing corrosion and rust spread.

Hot-dip galvanized paint is highly effective in various applications, including important steel structures for roads, bridges, construction projects, power towers, tunnel projects, construction machinery and equipment, containers, structural steel, communication transmission systems, signage, ship carbon steel plates, and machinery. The use of hot-dip galvanized paint yields significant results.

The purpose of the heat treatment process is to improve the performance of seamless steel pipes and fine seamless steel pipes in industrial equipment, eliminate thermal stress, and improve the machining and manufacturing performance of the composite materials of seamless steel pipes.

Thick-walled seamless pipes require training in quenching equipment for heat treatment technology.

According to the purpose of heat treatment technology, heat treatment technology can be divided into preheat treatment technology and post-treatment technology.

1. Preheat Treatment Preparation

The purpose of preheat treatment preparation is to improve manufacturing performance, eliminate internal stress, and prepare high-quality aluminum alloy components for heat treatment technology. Heat treatment methods include annealing, normalization, timeliness, and heat treatment.

2. Quenching Treatment

Quenching treatment is mainly used to eliminate internal stress caused by blank production processing and mechanical processing and manufacturing.

To avoid excessive transportation workload, for parts with general accuracy, one quenching treatment before precision machining is sufficient. However, for parts with high precision requirements (such as the casing of coordinate milling machines), the production process should involve 2 or multiple quenching treatments. Simple parts generally do not undergo quenching treatment.
