The spiral welded pipe hydraulic testing machine is mainly used for the pressure test of the spiral welded pipe to check the defects of the steel pipe and to eliminate a certain degree of residual strength of the pipe body. The equipment adopts polyurethane end face sealing, cooperates with oil-water balance system, and uses computer recording, storage and printing integrated process to display experimental results, which has the advantages of stable pressure holding and high safety.
