BS EN 10219-1 Spiral Submerged Arc Welded Pipe - Simple Clarification
Important Correction: Wrong Standard
BS EN 10219-1 is NOT for spiral submerged arc welded (SSAW) pipes!
Its actual title:
BS EN 10219-1: Cold formed welded structural hollow sections - Part 1: Technical delivery conditions
What It ACTUALLY Covers:
| Aspect | Description |
|---|---|
| Product | Structural steel tubes (for buildings, bridges) |
| Process | Cold-formed + Electric Resistance Welding (ERW) |
| Shape | Square, rectangular, circular hollow sections |
| Application | Construction, NOT pipelines |
| Excluded | Submerged arc welding, spiral welding |
The CONFUSION Explained:
People confuse it because:
Both are "welded tubes"
Both can be circular
Similar standard numbers (EN 10219 vs EN 10208)
CORRECT Standards for SSAW Pipes:
| For This Purpose | Use This Standard |
|---|---|
| Oil/Gas Pipelines | EN 10208-2 |
| Water Pipelines | EN 10224 |
| Structural Piling | EN 10219-2 (but check carefully) |
Quick Comparison Table:
| Feature | EN 10219-1 (Structural) | SSAW Pipeline Pipes |
|---|---|---|
| Use | Buildings, bridges | Oil/gas/water transmission |
| Welding | Electric Resistance (ERW) | Submerged Arc Welding |
| Seam | Straight | Spiral/helical |
| Pressure | Not for pressure | High pressure capable |
| Testing | Basic | Extensive NDT required |
Simple Rule:
If you need spiral welded pipe for pipelines:
❌ NOT EN 10219-1
✅ USE EN 10208-2
If you need structural hollow sections:
✅ USE EN 10219-1
Common Mistake:
Wrong: "BS EN 10219-1 SSAW pipe for pipeline"
Correct: "EN 10208-2 SSAW pipe for pipeline"
Remember: EN 10219 series = Structural sections (buildings)
EN 10208 series = Pipeline pipes (oil/gas/water)
