Pipe Drawing Service
Pipe drawing is a specialized cold-working process used to convert round pipes into square and rectangular hollow sections with improved dimensional accuracy and higher mechanical strength. We provide professional pipe drawing services in India for manufacturers and fabrication units that require precise hollow sections with enhanced load-bearing capacity and uniform wall thickness.
This process improves the mechanical properties of the pipe by refining the grain structure and increasing strength without adding material. The drawn square and rectangular hollow sections are widely used in structural, engineering, automotive, and fabrication applications where strength, consistency, and dimensional control are critical.
Process Overview
In pipe drawing, a round pipe is passed through a specially designed die and mandrel to form square or rectangular sections. The cold drawing process reduces tolerances, improves surface finish, and increases mechanical strength due to work hardening. This method produces hollow sections with:
- Accurate corner radii
- Uniform wall thickness
- Improved straightness
- Better dimensional control
The result is a stronger and more consistent product compared to conventionally formed sections.
Materials We Work With
We provide pipe drawing services for a wide range of metals commonly used in Indian industries, including:
Stainless Steel
Alloy Steel
Carbon Steel
Mild Steel (MS)
Precision Steel Tubes
Section Shapes & Size Range
We offer pipe drawing for the following hollow sections:
Square Hollow Sections (SHS)
Rectangular Hollow Sections (RHS)
Size range and wall thickness can be customized based on raw pipe dimensions and drawing feasibility. Close tolerances can be achieved compared to roll-formed sections.
Quality Control & Inspection
Each drawn pipe is checked for:
Dimensional accuracy
Wall thickness uniformity
Straightness
Surface finish
Mechanical property consistency
Test reports and inspection documentation can be provided as per requirement.
Mechanical Advantages of Drawn Hollow Sections
Pipe drawing significantly enhances mechanical performance due to controlled deformation. Benefits include:
- Higher tensile strength
- Improved yield strength
- Better load distribution
- Reduced internal stress variation
- Improved consistency across batches
These properties make drawn hollow sections suitable for demanding structural and engineering applications.

Frequently Asked Questions
Q1. Why choose pipe drawing instead of roll forming?
Pipe drawing provides better dimensional accuracy, tighter tolerances, and higher mechanical strength compared to roll-formed hollow sections.
Q2. Does pipe drawing increase strength?
Cold drawing increases tensile and yield strength due to work hardening of the material.
Q3. Can you draw stainless steel pipes?
We provide pipe drawing services for stainless steel as well as carbon and alloy steels.
Q4. Are wall thickness and corner radius consistent after drawing?
The drawing process ensures uniform wall thickness and controlled corner radii throughout the section.
