BAOLAI Sch10 Fire Sprinkler Pipes For Fire Fighting System

What is BAOLAI Sch10 Fire Sprinkler Pipes?

BAOLAI manufactures UL-listed and FM-approved fire sprinkler pipes used in fire sprinkler systems. Sch10 fire sprinkler pipes is a specially designed, lighter-weight steel pipes with a specific wall thickness, used in fire protection systems, and manufactured to meet stringent industry standards for safety and performance.

Sch10 fire sprinkler pipes is typically made from steel, often carbon steel (meeting standards like ASTM A135 or ASTM A795) or stainless steel (meeting standards like ASTM A312). Stainless steel offers enhanced corrosion resistance, especially in certain environments.

Approvals and Standards

Fire sprinkler pipes, including Schedule 10, must meet rigorous safety and performance standards. Common approvals and standards include:

• • UL Listed (Underwriters Laboratories): Indicates that the product has been tested and meets specific safety standards.
  • FM Approved (Factory Mutual): Signifies that Factory Mutual has tested the product and meets their standards for property loss prevention.
  • ASTM A135, ASTM A795: These are common ASTM (American Society for Testing and Materials) standards that specify the manufacturing and material requirements for steel pipe, often including fire protection applications.

Key Characteristics and Specifications of BAOLAI Sch10 Pipe 

Wall Thickness: The wall thickness of a Schedule 10 pipe is thinner than a Schedule 40 pipe of the same nominal size. The exact thickness varies depending on the pipe’s nominal pipe size (NPS). This thinner wall makes the pipe lighter and more cost-effective.

Approvals and Standards: Sch10 fire sprinkler pipes are manufactured to meet specific industry standards to ensure safety and reliability. They are typically:

• UL (Underwriters Laboratories) Listed.
• FM (Factory Mutual) Approved.
• Manufactured to standards like ASTM A135, ASTM A795, or ASTM A53.

Working Pressure: Schedule 10 fire sprinkler pipes are generally rated for a working pressure of up to 300 psi.

Finishes: They are available in both black and hot-dip galvanized finishes. Galvanized pipes are required for dry systems to meet specific zinc coating specifications.

Corrosion Resistance: Manufacturers may apply special coatings, such as a proprietary mill coating or an antimicrobial coating (like MIC Shield), to the inside of the pipe to inhibit corrosion. This is a crucial consideration, as corrosion can compromise a sprinkler system’s performance and longevity.

Applications of Sch10 Fire Sprinkler Pipes

Due to its thinner wall, Schedule 10 pipe is generally used in low to moderate pressure applications. In fire sprinkler systems, it’s a common choice because it offers a balance of durability, corrosion resistance, and cost-effectiveness. It’s often approved for systems with working pressures of 300 psi or less.

• Wet systems: Systems where pipes are constantly filled with water.
• Dry systems: Systems where pipes are filled with pressurized air or nitrogen and water is released only when a sprinkler head is activated.
• Pre-action and Deluge systems: Specialized systems used in areas where accidental water discharge could cause significant damage.

Advantages of Schedule 10 Fire Sprinkler Pipes

• Lighter Weight: Compared to higher schedule pipes, Sch10 is lighter, which can make installation easier and potentially reduce labor costs.
• Cost-Effective: Less material generally means a lower manufacturing cost.
• Corrosion Resistance: Many Sch10 pipes are manufactured with coatings (like black enamel or proprietary mill coatings, or hot-dip galvanizing for dry systems) or are made from corrosion-resistant materials (like stainless steel) to extend their lifespan and reduce maintenance. Some even have antimicrobial coatings to inhibit microbiologically influenced corrosion (MIC).
• Adaptability: It’s available in various sizes (from 1/2 inch to 12 inches or more) and can be used in various types of sprinkler systems (wet, dry, deluge, preaction)
