JIS G3452 SGP pipe is a hot-dip galvanized, carbon steel welded pipe designed for ordinary piping applications. It is manufactured from mild carbon steel strips that are formed into a round tube and welded longitudinally. After welding, the pipe is pickled, galvanized, and coated to ensure superior corrosion resistance and enhanced durability in general service environments.
Standard: JIS G3452 (SGP)
Size Range: 15 mm – 200 mm outside diameter
Schedule/Thickness: SCH10–SCH40 (varies by diameter)
Length: Random (up to 12 m) or cut-to-length per order
Surface Treatment: Hot-dip galvanizing (≥ 610 g/m² zinc coating)
Below is a comparison of five analogous carbon steel piping grades and their typical chemical compositions (wt %):
| Grade | C (max) | Si (max) | Mn (max) | P (max) | S (max) |
|---|---|---|---|---|---|
| JIS G3452 SGP | 0.25 | 0.35 | 1.20 | 0.040 | 0.050 |
| ASTM A53 Gr. B | 0.30 | 0.40 | 1.20 | 0.050 | 0.050 |
| EN 10255 L (Grade I) | 0.25 | 0.50 | 1.50 | 0.050 | 0.050 |
| GB/T 3091 Q195 | 0.22 | 0.35 | 1.40 | 0.045 | 0.050 |
| GOST 3262 ST3 | 0.25 | 0.50 | 1.60 | 0.040 | 0.050 |
Typical mechanical performance of these analogous grades is summarized below:
| Grade | Yield Strength (min) | Tensile Strength (range) | Elongation (min, 5 d) |
|---|---|---|---|
| JIS G3452 SGP | 245 MPa | 410 – 550 MPa | 21 % |
| ASTM A53 Gr. B | 205 MPa | 360 – 480 MPa | 25 % |
| EN 10255 L (Grade I) | 195 MPa | 280 – 430 MPa | 30 % |
| GB/T 3091 Q195 | 195 MPa | 315 – 430 MPa | 28 % |
| GOST 3262 ST3 | 205 MPa | 350 – 500 MPa | 26 % |
Corrosion Resistance: Hot-dip galvanizing provides a thick, uniform zinc layer for long-term protection.
Dimensional Accuracy: Precision welding and forming ensure consistent wall thickness and roundness.
Weld Quality: Longitudinal seam welds are inspected to meet strict non-destructive testing criteria.
Versatility: Wide range of sizes and schedules suitable for low-pressure services.
Cost-Effective: Economical production process with reduced material wastage.
JIS: JIS G3452 SGP
ASTM: ASTM A53/A53M (Gr. A/B)
EN: EN 10255 (formerly BS 1387)
