Product Description
What are ASTM A795 Fire Sprinkler pipes?
ASTM A795 Fire Sprinkler pipes is a specific type of carbon steel pipe designed and manufactured exclusively for use in fire protection systems. It’s a standard set by the American Society for Testing and Materials (ASTM) that covers both black and hot-dipped zinc-coated (galvanized) welded and seamless steel pipe.

ASTM A795 vs.ASTM A53 & ASTM A135 Fire Sprinkler Pipe Standards
While other standards like ASTM A53 and ASTM A135 also cover fire steel pipe, ASTM A795 is specifically tailored for fire protection system use, making it the primary standard for fire sprinkler piping.
- ASTM A53: This is a broader standard for steel pipe used in general mechanical and pressure applications (e.g., steam, water, gas lines). While A53 pipe can be used in fire protection systems, A795 has more specific and rigorous requirements directly related to fire safety. A53 covers three manufacturing technologies: continuous butt welding (Type F), resistance welding (Type E), and seamless steel pipe (Type S).
- ASTM A135: This standard specifically covers electric-resistance-welded (ERW) steel pipe, suitable for fire protection purposes. While A135 is used for fire sprinkler pipe, A795 is more comprehensive as it also includes seamless pipe and typically has more stringent quality controls for fire protection.
In essence, ASTM A795 provides a dedicated and robust set of requirements to ensure the reliability and safety of pipes used in critical fire suppression systems.
