High Pressure φ≤89mm 70Mpa 2-Station Pipe Inspection Line for OCTG Tube Mill Hydro Tester

Overview

φ≤89mm 70Mpa 2-Station OCTG Tube Mill Hydro Tester is purpose-built for hydrostatic pressure testing of seamless and welded pipes covering diverse outer diameters to identify concealed inherent defects. Before pressurisation, pipe ends are hermetically sealed using either large-clearance radial sealing or end-face sealing, followed by high-pressure water filling into the pipe bore. Test pressure is held compliant with applicable industrial standards to validate seal tightness and detect any leakage. All test data is automatically logged to a dedicated database for full traceability and archived record access. Designed with dual manual and automatic control modes, the unit achieves reliable, secure and eco-friendly operation.

Tailored Oil Pipes Hydrostatic Testing Mchine with diverse diameter also could be manufactured by our factory according to your specification.

Process Flow

The hydraulic pressure test has three processes: pipe flushing, pressure testing and water drainage, and they are run in sequence as follows:

Pipe feeding bed 1→ flipping pipe 1→ pipe flushing → flipping pipe 2 → pipe feeding bed 2→ lateral movement chain → test pressure (clamping → radial pre-sealing → water injection → pipe end sealing→ pressure increase → pressure holding → pressure relief → water discharge → clamp loosening→ lateral movement)  → pipe feeding bed 3 (discharge pipe bed) → water drainage- flipping pipe 3 → storage bed
