Hydrotester is mainly used for testing the pipe. It adopts polyamine end sealing and internal support large gap sealing two kinds of sealing method. Besides, this line has oil-water balance system. The industrial computer can record, store, and print the testing results. The hydrotester has the advantages, such as stable pressure maintaining, high safety.The hydrotester in our company can test the pipe from Φ219 to Φ5000mm. Max. testing pressure is 50Mpa.

Weld Seam Grinding Machine

For the submerged-arc welding pipe, the welding seam has the surplus. Before having the beveling and hydrotesting, the both sides of pipe need to be grinded. Internal & external grinder can take the role of manual grinding to save the labor, decrease the labor intensity, and improve the production efficiency.

Deslagging Machine

After the submerged arc welding, the residual welding flux and peeling welding slag stay in the pipe. It is not easy to clean for the small size pipe. Traditionally, the crane hangs up one side of pipe to clean the slag. This kind of method occupies the crane and it is not safety. The deslagging is not enough. The deslagger can incline the pipe and rotate the pipe to clean the welding slag. It also can save the crane source with high safety.
