What is a CR pipe?
A CR pipe is a welded steel pipe or tube made from cold rolled steel strip. The strip is rolled at or near room temperature, then formed and welded (ERW) into a round, square or rectangular section. The result is a clean, bright surface, uniform wall thickness and close dimensional control.
CR pipe full form
CR = Cold Rolled. You will also see the same product called cold rolled pipe, CR tube, C R pipe or, loosely, CRCA pipe (after the cold rolled close annealed strip it is made from).
CR pipe vs HR pipe
| Feature | CR pipe (cold rolled) | HR pipe (hot rolled) |
|---|---|---|
| Raw material | Cold rolled strip | Hot rolled strip |
| Surface finish | Smooth, bright, paint-ready | Rougher, mill scale present |
| Dimensional tolerance | Tighter | Wider |
| Wall thickness | Thin to medium gauges | Medium to heavy gauges |
| Cost | Higher per kg | Lower per kg |
| Typical use | Furniture, appliances, racks, gym equipment | Structures, general fabrication, scaffolding |
Note: Surface and tolerance are the main reasons to pay more for CR. If the pipe will be hidden or heavily welded, HR/MS pipe is usually the economical choice.
Where CR pipes are used
- Furniture: office chairs, tables, cots, school furniture, racks
- Home appliances: frames and stands, fans, coolers
- Automobile and two-wheeler parts: light tubular components
- Fitness equipment: gym frames and handles
- Electrical enclosures and display units that need a smooth finish
How to choose a CR pipe
- Shape and size: outside diameter (or side lengths) in mm
- Wall thickness: thinner saves weight, thicker adds stiffness
- Length: standard 6 m or cut-to-length for less wastage
- Finish: plain, oiled or ready for plating and powder coating
- Quantity and delivery city so freight can be quoted correctly
