A round tube (CHS — Circular Hollow Section) is a hollow structural section with a circular cross-section. It can be manufactured as seamless, ERW welded, or spiral welded, and is available in carbon, alloy, and stainless steel grades.
Q: What are the key characteristics of round tubes?
Isotropic cross-section — uniform strength in all directions Excellent resistance to internal pressure (ideal for fluid and gas transport) Lowest drag coefficient of all cross-section shapes Smooth exterior surface — minimal wind resistance Easy to bend and curve for architectural applications
Q: What are the typical applications of round tubes?
Fluid and gas transport piping (water, oil, gas) Handrails, guardrails, and balustrades Agricultural irrigation and sprinkler systems Sign and billboard poles Boiler tubes, condenser tubes, and heat exchangers
