Stainless steel pipes are essential components across a wide range of industries due to their excellent corrosion resistance and mechanical properties. Among them, the D90 seamless stainless steel pipe, with its precise dimensions and high-quality finish, stands out as a prime example of advanced stainless steel technology. This article explores the manufacturing process and diverse application areas of the D90 seamless stainless steel pipe.
I. Manufacturing Process of D90 Seamless Stainless Steel Pipe
The D90 seamless stainless steel pipe refers to a stainless steel pipe with a nominal outer diameter of 90 mm, manufactured without welded seams. It is produced using sophisticated techniques to ensure superior quality, durability, and performance. The key stages in its production include:
Raw Material Selection
Premium-grade stainless steel billets or plates are selected to ensure excellent corrosion resistance, strength, and workability.
Hot Rolling and Cold Drawing
The raw material undergoes hot rolling followed by cold drawing, where it is repeatedly heated, extruded, and drawn to form a uniform, seamless tubular structure.
Pickling and Surface Polishing
After forming, the pipe is treated with acid pickling to remove surface oxides, followed by polishing to enhance surface smoothness and aesthetic appeal.
Sizing and Wall Thickness Control
The pipe is calibrated to achieve precise outer diameter and wall thickness specifications, ensuring consistency and compliance with industry standards.
Heat Treatment
Heat treatment is applied to relieve internal stress from processing, improve mechanical properties, and enhance the pipe’s corrosion resistance.
