The invention provides an oil tube hydrostatic testing system, relates to a system for using a hydrostatic test, and particularly relates to the oil tube hydrostatic testing system. The oil tube hydrostatic testing system comprises a feeder, a transmission machine, a pressurizing system and a discharging machine, which are connected in sequence; a stopping block is arranged at the end point where the transmission machine is connected with the pressurizing system; and a stopping device is arranged on the transmission machine. According to the oil tube hydrostatic testing system provided by the invention, the stopping device is arranged on the transmission machine; and the corrosion noise among oil tubes is reduced by improving resistance when the oil tubes slide through a stopping effect. Therefore, the oil tube hydrostatic testing system is beneficial to the body health of a production participant. The oil tube hydrostatic testing system provided by the invention has the advantages of simple structure and very high practical applicability.
