Product Description:

The introduction of spiral welded pipe/straight seam submerged arcwelded pipe hydrotester

Spiral welded pipe/straightseam submerged arc welded pipe hydrotester mainly is used to have the pressuretesting to spiral welded pipe or straight seam submerged-arc welded pipe. Ituses polyamine to have the end sealing and inner supporting large gas sealingmethods. It is assisted by oil water balance system. Besides, the computer canrecord, store, print and testing the results. Its advantages include pressuremaintaining stability, high safety and so on

The machine adopts the structure of the symmetrical plate tension rod, the center of force is in the symmetry center of the pull rod when testing pressure; the pull beam width on both sides is greater than the maximum diameter of the pressuretesting steel pipe, to ensure both sides security of the hydraulic press when testing pressure, the structuredesign is simple, the strength and stiffness superior, performance stable, easy to maintain and use;


1 Pressurizing ways use high pressure intensifier.

2 The control system uses the system of “industrial computer (touch screen) +PLC", has automatic / manual / maintenance three work ways.

3. PLC selects Siemens S7-300/400 series, operation stable; control simple and flexible, has good scalability

4 The high-pressure water pump adopts frequency conversion control, boost rapid and stable, holding pressure fluctuation is small.

5 The host PC (touch screen) software real-time displays by pictures, curves, texts, and data, simple and intuitive.

6 Pressure-testing parameter setting is convenient and flexible and has storage, later called directly.

7 Has a perfect diagnostic function, the computer will provide real-time fault information, easy to maintain.
