Product Description

Product Introduction

Fire pipeline special flanges are standard components used to connect fire water supply system pipelines, valves, and equipment, usually made of carbon steel, stainless steel, or ductile iron. Its core functions include:
1. Sealing guarantee: Zero leakage connection of high-pressure water flow is achieved through flange gaskets;
2. Quick disassembly and assembly: supports convenient operation during emergency maintenance or system expansion;
3. Structural strengthening: The pressure bearing capacity reaches PN16 or above (national standard GB/T 9119), adapting to the instantaneous high-pressure impact of fire pumps.
Material standards
1. Stainless steel flange (304/316L): corrosion-resistant, suitable for chemical fire protection systems;
2. Carbon steel flange (Q235B): economical and durable, widely used in civil fire pipe networks;
3 . Special coating treatment: Some products are coated with epoxy resin to prevent corrosion of underground pipelines.
Technical Parameter
1. Pressure rating: PN10~PN25 (corresponding to 1.0~2.5MPa);
2. Caliber range: DN50~DN600 (covering the demand from the fire main pipe to the branch pipe);
3 . Certification requirements: Must pass CCCF fire product certification and GB/T 9124 standard testing.
