Description
UL Approved Fire Sprinkler Steel Pipe Information
UL Approved Sprinkler Pipes SCH40 are approved by Underwriters Laboratories (UL) for use in fire sprinkler systems. The "SCH40" designation indicates that the pipe has a standard wall thickness according to the ASTM schedule system.
UL approval ensures that the sprinkler pipe meets the safety and performance standards set by UL for use in fire protection applications. This includes factors such as corrosion resistance, strength, and durability, as well as compliance with specific installation and performance requirements.
