1. Product Overview
Product Name
76-660mm High Frequency Pipe Shopping Mall Fire Protection Pipeline Tube
Core Standard & Product Positioning
This series of high-frequency (HFW) fire protection steel pipes is strictly manufactured in accordance with GB/T 3091, GB/T 13793, ASTM A795 and ASTM A53 international fire pipeline standards. Adopting advanced high-frequency longitudinal welding technology, covering complete outer diameter range of 76mm to 660mm. It is professionally customized for large shopping malls, commercial complexes, supermarket buildings and public commercial fire protection systems. With stable pressure resistance, zero leakage performance and fire safety certification compliance, it solves the hidden dangers of insufficient pressure resistance and easy aging of ordinary welded pipes in commercial building fire water supply and sprinkler systems.
Core Features for Mall Fire Projects
Different from ordinary structural and fluid pipes, this HFW fire protection tube is optimized for commercial building fire safety standards. It features uniform weld texture, excellent hydraulic pressure resistance, stable low-temperature toughness and long-term anti-aging performance. Fully adapting to long-term standby, instant high-pressure water supply working conditions of shopping mall fire pipelines, it meets the strict fire safety acceptance standards of large public commercial buildings, ensuring stable operation of fire sprinkler, fire hydrant and water supply main pipelines.
