Material & Executive Standards
This oil depot fire fighting pipeline adopts high-purity Q235B fire-grade carbon steel with stable mechanical properties, excellent pressure impact resistance and low-temperature toughness. It strictly complies with GB 50074 Oil Depot Design Code, GB 50974 Fire Water Supply Specification, GB 50151 Foam Fire Extinguishing Standard and ASTM A53, EN 10219 international industrial fire protection standards. All finished pipes pass strict hydraulic strength test and airtightness test, meeting long-term standby and emergency high-pressure water supply requirements of petrochemical fire systems.
ERW Welding Technology for Oil Depot Fire Pipeline
Adopting closed-loop precision ERW electric resistance welding one-time forming process, the weld seam achieves complete metallurgical fusion with the pipe base metal. The weld structure is dense and uniform with no pores, cracks or micro-leakage defects, avoiding pipeline failure under emergency pressure surge. After professional internal and external weld flattening and polishing, the inner wall is smooth and flat, ensuring stable water flow rate and no pressure loss. High-precision dimensional tolerance ensures perfect matching with oil depot fire valves, spray ring pipes and fire pump supporting systems.
Exclusive Advantages for Oil Depot Fire Fighting System
1. High Pressure Resistance, Stable Emergency Water Supply
Optimized thick-wall structural design and integrated weld technology enable the pipe to withstand long-term static pressure and instantaneous high-pressure impact during fire startup. It maintains stable water pressure and rated flow for oil tank cooling water systems and fire hydrant pipelines, effectively preventing pipe burst and water supply interruption in emergency fire scenarios, fully meeting petrochemical high-risk site safety standards.
2. Industrial Anti-Corrosion, Adapt to Petrochemical Environment
Oil depot sites feature volatile oil gas, humid air and slight chemical corrosive media. This ERW fire pipe supports hot-dip galvanizing, epoxy anti-corrosion and black rust-proof treatment. It effectively resists oil gas erosion, atmospheric oxidation and environmental corrosion, preventing pipe wall rust thinning and leakage, ensuring long-term safe standby operation of fire pipe networks in flammable and explosive areas.
3. Smooth Inner Wall, No Scaling & Stable Hydraulic Performance
The polished seamless inner wall leaves no welding slag or dead corners, effectively avoiding sediment accumulation and scale formation during long-term standby fire water storage. It ensures 100% unobstructed pipeline flow, guarantees rapid response of tank spray cooling systems and fire hydrant water output, and reduces daily maintenance and pipeline dredging work for oil depot fire facilities.
4. High Structural Safety, Anti-Vibration & Anti-Deformation
Oil depot fire systems are linked with fire pump frequent startup and shutdown, generating continuous pipeline vibration. The integral ERW forming pipe body has high rigidity and strong vibration fatigue resistance, not easy to loose welds or deform. It adapts to long-term alternating vibration working conditions of petrochemical fire pipe networks, eliminating potential safety hazards.
5. Standardized Matching & Easy Safety Construction
All sizes and pipe end processing comply with oil depot fire protection construction specifications. Grooved and flange connection methods support rapid standardized installation of large-area tank farm fire pipe networks. Perfectly compatible with spray ring pipes, filter valves, control valves and vent valves required for oil depot fire systems, it meets strict petrochemical fire acceptance standards.
