Hydrostatic testing machines are our leading products. We have produced more than 60 steel pipe hydrostatic testers of different types since the founding of the company.
Our fully automatic hydrostatic testing machines are available in different types:
A. In terms of head, there are 4 types: single-head, double-head, three-head and four-head hydrotester;
B. In terms of displacement method, there are 3 types:tooth plate step-walking type, chain displacement type and tilting displacement type;
C. In terms of pressurizing method, there are 3 types: pneumatic cylinder pressure amplifier type, hydraulic cylinder pressure amplifier type and high pressure pump type; double-class pressure amplification is employed for hydrostatic testing machine for large diameters and high pressure to ensure quick pressure amplification;
D. In terms of sealing method, there are 4 types: end sealing type, outer diameter sealing type, combined outer diameter sealing type, and large clearance outer diameter type;
E. In terms of length adjustment method, there are 2 types: manual displacement type and motorized displacement type.
We produce hydrostatic testing machines ranging from 5MPa to 70MPa. The simpler end sealing is used for machines under 21MPa. We offer the end seal crushing stress control technology, which ensures long service life of seals (up to 2000 pipes per seal ring).
Based on the requirement of products, we can supply perfect software package which, in combination with pressure senor, provides all-inclusive functions including collection, storage, display, search and printing output of test data.
In addition, we can also supply all auxiliary functions such as steel pipe stocking, splitting, pre-rinsing, water pre-filling and post water draining then drying with compressed air.
The smallest hydrostatic testing machines produced in our company is the Φ76(Φ16-Φ76) 4-head hydrostatic testing machines with capacity of 12 pipes/min; the largest in the Φ457 single-head tester with capacity of 1pipe/min for Φ457 pipe;
We also produce single-end hydraulic testers for Φ340 coupling pipes, which using both the inner and outer seals at the coupling end, performs hydrostatic test separately on the coupling end of the coupling pipe.
