UL/FM Approved Red Painted Fire Sprinkler Steel Pipe - China Suppliers and Factory Direct Sales
Detailed Description of Fire Sprinkler Steel Pipe
Fire sprinkler steel pipes are intended for automatic fire sprinkler systems. The primary purpose of these pipes is to automatically activate in the initial stages of a fire, discharging water uniformly across the given protected location to either contain or extinguish the fire. Our fire sprinkler pipes are mainly manufactured of quality carbon steel (Q235B) as the base metal, and manufactured by the (electric resistance welded) ERW process to production uniformity in the weld and high pressure resistance.
🔴 Corrosion Protection Note: Corrosion protection of steel pipes is crucial in fire suppression systems because they usually have stagnant lines filled with water.
We offer two main types of external surface treatment:
① Red Epoxy Coating — Offers good corrosion resistance and easy identification within complex systems.
② Hot Dipped Galvanizing — Creates a layer of zinc-iron alloy on both the outside and inside of the pipe to combat corrosion, offering robust and long-term protection. This is a good option for dry pipe and pre-action systems, especially in corrosive environments.

Frequently Asked Questions (FAQ)
Q
What manufacturing process is used for fire sprinkler steel pipes?
Our fire sprinkler steel pipes are manufactured using the Electric Resistance Welded (ERW) process. This process ensures uniformity in the weld seam and delivers high pressure resistance, making the pipes reliable and suitable for automatic fire sprinkler systems.
Q
What are the available surface treatment options for fire sprinkler pipes?
We offer four surface treatment options: Red Epoxy Coated (Internal/External), Hot-Dip Galvanized, Black Painted, and Bare. Red epoxy coating provides easy visual identification and corrosion resistance, while hot-dip galvanizing provides a zinc-iron alloy layer for long-term protection, especially suitable for dry pipe and pre-action systems in corrosive environments.
Q
What standards and certifications do your fire sprinkler pipes comply with?
Our fire sprinkler steel pipes comply with multiple international standards including ASTM A795, ASTM A53, ASTM A135, UL 852, FM 1630, and GB/T 3091. They are also UL Listed, FM Approved, and CE Certified, ensuring they meet stringent fire safety and quality requirements worldwide.
Q
What size range and wall thickness options are available?
The pipes are available in sizes ranging from DN15 to DN300 (1/2" to 12") in NPS. Wall thickness options include Schedule 10 and Schedule 40, or can be customized as per specific standard requirements to suit your project needs.
Q
What connection types are supported for fire sprinkler steel pipes?
Our fire sprinkler steel pipes support three main connection types: Grooved, Threaded, and Welded. The choice of connection type depends on the specific system design, installation requirements, and applicable fire protection standards for your project.
Q
Can the pipe lengths be customized, and what are the standard lengths available?
Yes, pipe lengths are customizable to meet your specific project requirements. Standard lengths available include 5.8m, 6m, 11.8m, and 12m. Custom lengths can be arranged upon request to minimize on-site cutting and optimize installation efficiency.
