Hard Drawn Copper Tube for straight pipe runs
S K Metal supplies rigid copper tubing for buyers who require straightness, controlled dimensions and a specified drawn temper.
In addition, hard drawn tube is usually installed in straight runs or fabricated with appropriate tools and fittings. Its OD, wall, temper, surface condition and governing standard must suit the intended service. However, rigid tube should not be treated as interchangeable with annealed coil stock. Therefore, buyers should confirm the installation design and joining method before ordering.

Hard Drawn Copper Tube applications and options
First, confirm the system specification and straight-length schedule. Then select the required OD, wall, finish, end preparation and packaging.
Plumbing straight tube
In addition, suitable tube can serve hot and cold water systems when its dimensions and material meet the design.
Discuss plumbing sizes →Cleaned copper tube
However, applications with internal cleanliness requirements need specified cleaning, end sealing and documentation.
Review quality requirements →Cut-to-length tubing
Moreover, project schedules can define straight length, cut tolerance and end condition for installation or fabrication.
Prepare a length schedule →Heat-exchanger tube
Furthermore, equipment fabrication may require controlled OD, wall, straightness and surface condition.

How to specify Hard Drawn Copper Tube
Therefore, a complete specification helps prevent errors in OD, wall, temper, straight length, material standard and installation requirements.
- OD & wall
- First, provide outside diameter, specified wall thickness and dimensional tolerances.
- Temper
- Next, state the exact hard drawn or other drawn temper required by the governing specification.
- Length & straightness
- Also confirm standard or cut length, length tolerance and any straightness requirement.
- Material & standard
- Moreover, identify copper grade, applicable tube standard and project requirements.
- Surface & ends
- In addition, specify finish, internal cleanliness, end sealing and protective packaging.
- Service conditions
- Finally, provide medium, design pressure, temperature, joining method and equipment reference.
- Quantity & delivery
- Therefore, include piece quantity, packaging, inspection, delivery city and required date.
Important: Do not select rigid tubing by OD alone. The system designer should approve wall, temper, material, standard, pressure requirements, routing and joining procedure.
Applications
Applications of Hard Drawn Copper Tube
Because systems differ, the correct straight tube depends on dimensions, temper, material standard, joining method and operating conditions.
Air-conditioning lines
For example, suitable straight tube can be used in refrigerant systems when the equipment specification permits it.
Water distribution
Moreover, specified copper tube can serve compatible hot and cold water installations.
Heat exchangers
In addition, equipment builders may require controlled OD, wall, straightness and surface finish.
Medical gas projects
Furthermore, these projects require the exact approved tube standard, cleanliness and qualified joining process.
Industrial piping
However, material and pressure requirements must be checked against the specific service.
OEM fabrication
Therefore, repeat purchases should follow an approved drawing, material schedule and inspection plan.
Quality and documentation
Verify straight-tube dimensions and condition
Before ordering, define the OD, wall, temper, straightness, length, surface and cleanliness checks required for Hard Drawn Copper Tube. In addition, designers can review the Copper Tube Handbook for general information about copper tube and joining practices.
Discuss your material requirement →- OD, wall thickness and tolerance verification
- Temper, length and straightness checks
- Surface, cleanliness and end-condition review
- Material and inspection documents when quoted
- Protective packaging and size identification

Frequently asked questions
Hard Drawn Copper Tube FAQs
What is Hard Drawn Copper Tube?
It is copper tube supplied in a drawn temper with comparatively high rigidity. However, the exact temper must match the governing material specification.
Which dimensions are required for a quotation?
In addition, provide OD, wall, temper, straight length, tolerances and quantity for each size.
How is hard drawn tube different from annealed coil?
Hard drawn tube is comparatively rigid and commonly supplied in straight lengths. By contrast, annealed coil is more readily formed where its specification permits.
Can straight lengths be cut to size?
Availability depends on size and quantity. Therefore, state cut length, tolerance and end condition in the enquiry.
How should hard drawn tube be joined?
The approved method depends on the service and tube specification. Consequently, state the required brazing, soldering or mechanical joining procedure.
Can inspection documents be requested?
Yes, subject to availability by order. Finally, list material, dimensional and traceability documents when requesting a quote.
