Steel Pipes for Fire Fighting Systems in Saudi Arabia
Steel pipe requirements for fire sprinkler and fire water systems in Saudi Arabia: NFPA standards, ASTM A53/A795/A135, listed pipe, grooved joints, schedules and Civil Defense approvals.

Short answer: Fire fighting piping in Saudi Arabia is typically designed to NFPA standards (such as NFPA 13 for sprinklers and NFPA 14 for standpipes) as adopted by the Saudi Fire Code and Civil Defense. Steel pipe to ASTM A53, A135 or A795 is commonly used, in schedules permitted by NFPA, often with grooved or threaded joints and UL/FM listed components.
Fire protection systems are life-safety systems. Pipe selection must follow the design, the code and the approving authority — this guide summarises what buyers typically encounter.
Codes and authorities
- Saudi Building Code — SBC 801 (Fire Code) sets fire protection requirements
- NFPA 13 (sprinklers), NFPA 14 (standpipes) and NFPA 24 (private fire service mains) are widely referenced
- Civil Defense reviews and approves fire protection designs and installations
Common pipe standards
| Standard | Notes |
|---|---|
| ASTM A53 | Welded and seamless, black or galvanized |
| ASTM A135 | ERW pipe, including lighter walls |
| ASTM A795 | Black and galvanized pipe specifically for fire protection |
Some projects require UL-listed or FM-approved pipe and components; check the specification.
Schedules and joining
| Joining method | Typical wall |
|---|---|
| Threaded | SCH 40 for smaller sizes |
| Roll-grooved | SCH 10 or SCH 40, per listing |
| Welded | Per NFPA and design |
Grooved couplings are popular for speed and flexibility.
Black vs galvanized
Wet systems often use black steel; dry and pre-action systems, where trapped moisture and oxygen cause corrosion, often use galvanized pipe. MIC (microbiologically influenced corrosion) and water quality are design considerations.
Fire water mains and tanks
Underground mains may use ductile iron, HDPE or coated steel. Fire water storage tanks are typically designed to NFPA 22 — see steel storage tanks.
Buying checklist
- Standard and schedule match the approved design
- Listing/approval documents where required
- Mill certificates and hydrotest records
- Correct end finish (threaded, grooved, plain)
- Coating as specified
