Cold-Drawn Seamless Steel Pipes, also known as precision-drawn tubes or cold-finished seamless pipes, represent our high-precision product line manufactured through advanced cold-drawing technology. These precision cold-drawn tubes are produced by drawing seamless steel billets through precision dies at room temperature, resulting in superior dimensional accuracy, excellent surface finish, and enhanced mechanical properties that significantly outperform conventional hot-rolled pipes.

Cold-Rolled Steel Tubes, also known as fine-rolled seamless tubes, are manufactured through an advanced process where steel shells are precisely rolled over mandrels using controlled roller systems. This sophisticated rolling technology applies calculated radial pressure while maintaining steady axial movement, producing tubes with exceptional dimensional consistency and reliable mechanical properties.

Quenched and Tempered Steel Pipes (Q&T ) represent advanced heat-treated steel tubes that undergo precise "quenching + high-temperature tempering" processes. These special heat-treated tubes are engineered to achieve optimal balance between strength and toughness through the formation of tempered sorbite microstructure, making them ideal for heavy-load and high-pressure applications in demanding working conditions.
lnquiryDetail
Normalized Steel Pipes (NBK/+N Condition) represent a standardized delivery state where steel tubes undergo normalizing heat treatment after cold forming processes. These normalized seamless tubes are heated to 30-50°C above Ac3 (for hypoeutectoid steel) or Accm (for hypereutectoid steel) temperatures, maintained at this level, then cooled in air to achieve refined microstructure and balanced mechanical properties.
