Seamless vs Welded — Which Pipe to Choose?
| Key Item | Seamless Pipe | Welded Pipe |
|---|---|---|
| Manufacturing | Formed without a weld seam | Formed from strip/coil with welded seam |
| Pressure Performance | Excellent for high-pressure and critical service | Suitable for many systems; spec depends on grade and NDT requirements |
| Size & Availability | Broad wall thickness range; custom production | Fast lead time and wide availability in common sizes |
| Typical Uses | Process piping, boilers, high-pressure lines, critical fluids | Structural tubing, general piping, decorative/architectural tube |
| Cost & Lead Time | Higher cost; longer lead time for specials | Often more cost-effective with shorter lead time |
