Product Description
Suitable for hydrostatic pressure test of steel pipes with outer diameter of 25mm~88.9mm, le-ngth of 4~6m, and pressure ≤4Mpa.
The hydraulic press adopts the middle pipe inlet and outlet type, the clamp is set at the central
pressure test station of the hydraulic press, and the pipe inlet/outlet is automatically lifted and
moved.
The steel pipe with a spray port welded on the pipe requires the buyer to manually assist the s-
ingle pipe inlet.
Steel pipe O.D. 25~48.3mm,0.8mm alarmed automatically if have leakage hole;
Steel pipe O.D. 60.3~88.9mm,2.0mm alarmed automatically if have leakage hole.

1.1.4 Steel pipe parameters
1 Outer diameter of steel pipe (mm): ¢33.4mm~88.9mm;

3 Wall thickness of steel pipe (mm): mm
4 End form of pipe: with groove or thread
Process flow
Material storage rack → the step-by-step pipe moving device moves four steel pipes to the material waiting rack →
the horizontal feeding conveying device rises and horizontally moves the steel pipe to be pressure tested to the pr-
essure testing station of the hydraulic press → clamps → the pressure test heads at both ends move forward → pip-
e end seals → water injection and exhaust → exhaust valve closes → water injection valve closes → pressurization
→ pressure maintenance → pressure relief → pressure test heads at both ends move back → release the clamps →
steel pipes are sent out → next cycle.
