With the continuous improvement of China's economy, it has driven the rapid development of energy industries such as oil and gas, as well as the prosperity of the steel pipe industry and pipeline

Compared with other non-destructive testing methods, the water pressure test of steel pipes has the following advantages: 1. It can expand larger size defects to the critical size, thereby exposing si

1. Research on sealing performance: sealing parts with steel pipe end face, outer diameter end face or radial sealing, as well as sealing performance of various hydraulic cylinders and valve bodies; 2

An electro-hydraulic proportional valve is a hydraulic component that can adjust and control the pressure, direction, and flow rate of liquid flow in proportion to changes in input electrical signals.

1. Responsible for the use, maintenance, and adjustment of the hydraulic press, and conducting static water pressure tests on each steel pipe in accordance with product standards and technical require

After the pressure test of the pipeline is completed by a large-scale pipeline water pressure testing machine, it is necessary to drain the pipeline. Currently, the drainage method is to open the seal
