JIS G3452 SGP Carbon Steel Welded Pipe Hot Dip Galvanized Steel Pipe For Ordinary Piping

Material Overview

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.

Specifications

  • 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)

Chemical Composition

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

Mechanical Properties

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 %

Key Features

  • 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.

Applicable Standards

  • JIS: JIS G3452 SGP

  • ASTM: ASTM A53/A53M (Gr. A/B)

  • EN: EN 10255 (formerly BS 1387)

  • GOST: GOST 3262

  • GB: GB/T 3091

Application Fields

  1. Water Supply and Distribution

    • Service lines, mains, and branch piping for potable water systems.

  2. Gas and Air Piping

    • Low-pressure natural gas distribution, compressed air networks.

  3. Heating, Ventilation, and Air Conditioning (HVAC)

    • Chilled water, radiator connections, boiler feed lines.

  4. Construction Scaffolding and Framework

    • Temporary structures, handrails, and support scaffolding.

  5. General Industrial Piping

    • Conveyance of non-corrosive liquids and gases in manufacturing plants.
