Product Description

Cold Rolled / Drawn vs. Hot Finished Pipes

Property Cold Rolled / Cold Finished Hot Finished / Hot Rolled
Dimensional Tolerance Extremely tight (typically 0.05 mm to 0.15 mm) Broader (typically 0.5 mm or higher)
Surface Finish Smooth, shiny, scale-free (Ra 0.41.6 m) Rough, dark oxide mill scale
Mechanical Strength Higher yield & tensile strength due to work hardening Lower yield strength, higher ductility
Wall Thickness Uniformity Superior wall concentricity Standard eccentricity variation
Cost Higher (requires extra processing steps & annealing) Lower (direct hot extrusion/piercing)

Common Production Methods

  1. Cold Pilgering (Cold Rolling): A cold reduction method where multi-roll passes compress the pipe over a stationary tapered mandrel. Ideal for heavy wall reductions, high alloy steels (like AISI 4140, 4340, or stainless grades), and precise inner diameter (ID) control.

  2. Cold Drawing (DOM / CDS): The pipe is pulled through a die and over an internal plug or mandrel. Used extensively for producing Drawn Over Mandrel (DOM) welded tubing and Cold Drawn Seamless (CDS) precision pipes.

Typical Applications & Standards

  • Hydraulic & Pneumatic Cylinders: Requires honed internal surfaces and strict roundness.

  • Automotive & Aerospace: Drive shafts, steering columns, and high-strength structural tubing where weight-to-strength ratio is critical.

  • Precision Mechanical Components: Bushings, bearing sleeves, and machined tubular parts.

Common Standards:

  • ASTM A513 (Type 5 / Type 6): Electric-resistance-welded carbon and alloy steel tubing (DOM).

  • ASTM A519: Seamless carbon and alloy steel mechanical tubing.

  • EN 10305 (Parts 1 & 2): Steel tubes for precision applications (seamless cold drawn and welded cold drawn).
