PRODUCT INTRODUCTION

Cold Drawn Seamless Cylinder Tube

a high-precision steel tube produced through a cold drawing process that enhances its dimensional accuracy, surface finish, and mechanical properties. CDS tubes are widely used in industries where precision, strength, and performance are critical.

Key Features:

Seamless Construction:

Made without welds, providing uniform strength and eliminating weak points.
Ensures better pressure handling compared to welded tubes.

Cold Drawing Process:

Involves pulling the tube through a die to achieve precise dimensions and a smooth surface finish.
Results in enhanced mechanical properties and tighter tolerances.

Material Options:

Commonly available in carbon steel (SAE 1020, 1026, 1035; A 106 grade A, B, C; E355, ST52, ST37.4,) and alloy steel.
Suitable for applications requiring high strength and durability.

High Dimensional Precision:

Tolerances conform to international standards (DIN 2391, EN 10305-1).
Smooth inner and outer surfaces reduce friction and wear.

Mechanical Strength:

Offers excellent tensile strength, yield strength, and fatigue resistance.
Suitable for high-pressure applications.

Applications:

Hydraulic and Pneumatic Cylinders: Used as cylinder barrels or pipes due to their precision and durability.
Automotive Industry: Components such as drive shafts, shock absorbers, and steering systems.
Oil and Gas: For pipelines and high-pressure applications.
Construction and Machinery: Structural components requiring strength and precision.
General Engineering: Machine parts, rollers, and spindles.

Benefits of CDS Tubes:

Superior strength and performance.
Smooth surface finish for improved functionality and reduced wear.
Tight dimensional tolerances for precision applications.
Versatility across a wide range of industries.

CDS tubes are an industry standard for high-performance, precision-engineered applications, ensuring long-lasting reliability and efficiency.

Seamless Tube Manufacturing Process

We use a special method called Cold Drawn Process to make our seamless tubes. This process ensures that the tubes have a smooth surface and exact dimensions. After making the tubes, we heat treat them to give them the strength and properties they need. This involves relieving stress, normalizing it, and setting it according to specific standards and requirements. We use special equipment called roll straighteners to ensure the tubes are perfectly straight. We check the quality of our tubes very carefully to make sure they are top-notch. We also pack them with great care for export, so they arrive in perfect condition.

Industrial & Applications of Seamless Tubes

Many industries use seamless steel tubes for various important tasks. These include shipbuilding, power plants, oil refineries, chemical plants, steel factories, and fertilizer manufacturers.
