In order to further optimize the operation of natural gas pipeline，the natural gas drag reducer 1，3，5-benzenetricarboxylic acid tridodecylamide（BATD）was synthesized from 1，3，5-benzenetricarboxylic acid，p-toluenesulfonic acid，dodecylamine，etc. Its performance of drag reduction and corrosion in natural gas pipeline transmission was comprehensively evaluated by using atomization time and BATD dosage as variables，along with scanning electron microscopy. The results showed that BATD could firmly adsorb on the steel surface，significantly reduce the roughness of the steel surface，and significantly improve the transmission efficiency of the gas pipeline，and also had the effect of corrosion inhibition. When the atomization time was 60 min and BATD dosage was 6 g/L，the maximum drag reduction rate reached 13.32% and the slow release rate reached 85.12%. The film forming performance of BATD solution was good，which could reduce resistance and increase transportation.
