15CrMo square and rectangular steel pipes are an indispensable material in modern industry, widely used in petroleum, chemical, power, and machinery manufacturing industries. Their unique performance advantages not only meet specific engineering needs but also drive technological progress and development in related industries.
First, the material characteristics of the 15CrMo square and rectangular steel pipes
15CrMo, or 15CrMo steel, is a low-alloy high-strength structural steel. It contains certain amounts of chromium and molybdenum, and the addition of these alloying elements significantly improves the hardenability, hot strength, and oxidation resistance of the steel. Therefore, 15CrMo steel has high creep strength, high endurance strength, and good resistance to hydrogen, nitrogen, and ammonia corrosion. 15CrMo square and rectangular steel pipes are made from this high-quality steel through processes such as cold drawing or hot rolling. The structural characteristics of square and rectangular steel pipes enable them to perform excellently under complex stresses such as pressure, bending, and torsion, and they are easy to connect and install, greatly simplifying the construction process.
Second, the production process of 15CrMo square and rectangular steel pipes
The production process of 15CrMo square and rectangular steel pipes mainly includes raw material preparation, heating, piercing, rolling, cooling, finishing, and inspection. Piercing is the key step in forming the tubular structure, utilizing the metal’s plastic deformation ability at high temperatures to pierce solid round steel into hollow tube blanks. The rolling process uses multiple passes of rollers to gradually deform the tube blank into the desired square or rectangular cross-section.
The cooling stage is crucial for controlling the product’s microstructure and properties. Rapid cooling refines the grains, improving the steel’s strength and hardness, while slow cooling helps eliminate internal stress and improve toughness. The finishing stage includes straightening, end trimming, and surface treatment to ensure dimensional accuracy and appearance quality. Finally, rigorous physical and chemical testing and performance testing ensure that each batch of products meets relevant standards and customer requirements.
