National Fire Protection Association（NFPA）standards are required to be adopted to more and more overseas projects in terms of the fire protection design. The comparisons between NFPA standards and Chinese national standards, Technical code for fire protection water supply and hydrant systems(GB 50974—2014), are including:1)the fire water supply system with high steady pressure in NFPA standards; 2)the types and classifications of fire hydrant indoor and outdoor; 3)the rules about flow and head of fire pump，etc. Through the experience in overseas projects, we propose suggestions for the fire protection system design in China.
