Detailed Product Description

Cold Drawn Seamless Tube

1. Definition

A cold-drawn seamless tube is a cylindrical product that is manufactured by drawing a solid metal billet through a piercing rod to create a hollow tube without any seams or welds. This seamless construction sets them apart from other types of tubes, such as welded or hot-rolled tubes. The absence of seams enhances the tube’s structural integrity and resistance to various stresses, making it an ideal choice for critical applications.

2. Dimension

Outer Diameter	3.2-177.8 mm
Wall Thickness	2.2-25.4 mm
Length	SRL, DRL or according to customer's requirement

3. Production Process

Billet Preparation→Heating→Piercing→Elongation→Cold Drawing→Heat Treatment (Optional)→Surface Treatment

4. Application

Oil and Gas Industry	Pipelines: Cold drawn seamless tubes are used for transporting oil and gas over long distances due to their high strength and resistance to pressure.
	Downhole Tubing: These tubes are critical in drilling operations, providing structural integrity in high-pressure and high-temperature environments.
Power Generation	Boilers: Used in the manufacturing of boiler tubes that operate under high pressure and temperature, ensuring efficient heat transfer.
	Heat Exchangers: Employed in heat exchangers to transfer heat between fluids while maintaining structural integrity under thermal stress.
Automotive Industry	Hydraulic Systems: Cold drawn seamless tubes are often used in hydraulic cylinders and components, providing reliable performance in demanding conditions.
	Chassis Components: They are used in various structural components of vehicles due to their strength and lightweight properties.
Aerospace Industry	Aircraft Components: Used in manufacturing critical components of aircraft, such as landing gear and fuel lines, where high strength-to-weight ratios and reliability are essential.
	Engine Parts: Employed in the production of engine components that require precise dimensions and excellent mechanical properties.
Construction and Structural Applications	Support Structures: Cold drawn seamless tubes are used in scaffolding, support columns, and other structural applications where strength and durability are paramount.
	Frameworks: Utilized in various construction frameworks, providing robust support for buildings and infrastructure.
Medical Equipment	Surgical Instruments: These tubes are used in high-precision medical instruments due to their sterile finish and mechanical reliability.
	Implants and Prosthetics: Employed in manufacturing implants and prosthetic devices that require biocompatibility and strength.
Chemical and Petrochemical Industries	Pressure Vessels: Used in the construction of pressure vessels that store and transport chemicals under high pressure.
	Piping Systems: Employed in piping systems for transporting corrosive materials, often treated for enhanced corrosion resistance.

6. Packaging & Delivery

Packaging Method	Description	Benefit
Wooden Crates	Tubes are often packed in sturdy wooden crates that provide robust protection against physical damage during transit.	This method is suitable for large quantities and heavy-duty applications, preventing bending or deformation.
Steel Bundles	Tubes may be bundled together using steel straps or wire, ensuring they remain securely in place during transportation.	This method allows for efficient handling and maximizes space during shipping.
Plastic Wrapping	Individual tubes or bundles are wrapped in plastic film to shield them from moisture, dust, and contaminants.	Protects the surface finish and prevents corrosion during storage and transport.
Cardboard Boxes	Smaller quantities of tubes can be packaged in cardboard boxes, providing lightweight protection.	Ideal for easy handling and shipping, especially for less fragile items.
End Caps	Protective end caps are placed on the ends of the tubes to prevent damage during handling and transport.	Maintains the integrity of the tube openings and prevents contamination.
Pallets	Tubes can be stacked on wooden or plastic pallets for easier handling with forklifts and for organized storage.	Facilitates efficient loading and unloading processes.

Transportation Method	Description	Benefit
Road Transport	Trucks are commonly used for transporting cold drawn seamless tubes over short to medium distances.	Flexible and efficient for local deliveries and can navigate various terrains.
Rail Transport	Trains are utilized for long-distance transportation, especially for bulk shipments.	Cost-effective for large volumes and reduces road congestion.
Sea Freight	Containers are used to ship tubes internationally by sea, often combining them with other goods.	Economical for large shipments over long distances, although transit times are longer.
Air Freight	For urgent shipments, air freight can be used to transport tubes quickly to their destination.	Fastest transportation method, though more expensive and typically used for smaller quantities.
