Cold Drawn Seamless Tube Manufacturer & Supplier in India
Cold Drawn Seamless Tube (CDS Tube) is a high-precision seamless mechanical tubing manufactured through a cold drawing process to achieve superior dimensional accuracy, smooth surface finish, excellent strength, and tight tolerances. Commonly produced under ASTM A519 and ASME SA519 standards, CDS tubing is widely used in automotive, hydraulic cylinders, engineering machinery, construction equipment, and structural applications requiring high mechanical performance and reliability.
We supply ASTM A519 CD Seamless Carbon Steel Mechanical Tubing in grades such as 1018 CDS Tubing and 1026 CDS Tubing with customized sizes, thicknesses, and finishes for industrial applications across India and global markets.
What is a Cold Drawn Seamless Tube?
A Cold Drawn Seamless Tube is a seamless steel tube produced by drawing hot-finished seamless tubes through a die and mandrel at room temperature. This cold drawing process improves the tube’s dimensional precision, concentricity, tensile strength, machinability, and surface finish.
Unlike welded tubing, Cold Drawn Seamless (CDS) Tubes do not contain a welded seam, making them ideal for applications that require high pressure resistance, structural integrity, and superior mechanical properties.
As an experienced Cold Drawn Seamless Tubing Manufacturer in India, we supply precision-engineered tubes that comply with international standards including ASTM A519 and ASME SA519 specifications.

Manufacturing Process of Cold Drawn Seamless Tubing
The production of Cold Drawn Mechanical Tubing involves multiple precision-controlled stages to achieve superior quality and performance.
Step 1: Seamless Tube Formation
A solid steel billet is heated and pierced to form a hollow tube without any weld seam.
Step 2: Hot Rolling
The hollow tube undergoes hot rolling to achieve preliminary dimensions.
Step 3: Cold Drawing Process
The tube is drawn through dies and mandrels at room temperature to reduce diameter and wall thickness while improving tolerance accuracy.
Step 4: Heat Treatment
Depending on application requirements, tubes may be annealed, normalized, or stress relieved.
Step 5: Finishing & Inspection
Final processes include straightening, cutting, non-destructive testing, dimensional inspection, and surface finishing.
This manufacturing method makes Cold Drawn Seamless (CDS) Tubes highly suitable for precision engineering applications.
