Overview
120Mpa High Duty OCTG Hydrostatic Test Press Equipment for Pressure Testing of Seamless & Welded Steel Pipes.
Our factory’s hydrostatic testers are engineered to comply with API 5CT and other relevant standards. Depending on customer requirements, our machines employ either large radial gap sealing or end-face sealing to seal both ends of steel pipes.
High-pressure water is pumped into the pipe, and pressure is held for the specified dwell time to detect leakage. All test results are automatically stored in a database, enabling full traceability of inspection records. Hydrostatic tester configurations include single-station, double-station and multi-station models.
GH hydrostatic testers are built for seamless, ERW, LSAW and SSAW steel pipes, as well as stainless steel and alloy steel pipes. Each unit is custom-engineered to match your pipe specifications: outer diameter, wall thickness, pipe length, required test pressure and production throughput.
Equipped with a heavy-duty hydraulic frame, PLC automatic control system and high-pressure plunger pump, the equipment provides stable pressurization, reliable sealing and high operational efficiency for continuous industrial production.

Process Flow
The hydraulic pressure test has three processes: pipe flushing, pressure testing and water drainage, and they are run in sequence as follows:
(Loading Rack → Pipe Stop & Distributor) → Pipe Tilting → Alignment & Flushing → Standby Station → Feeding into Testing Machine → Clamping by Jigs → Both-End Test Heads Advance to Position → Pre-sealing → Water Filling & Venting → Pipe Body Pressure Boosting → Pressure Holding → Sequential Pressure Relief → Both-End Test Heads Retract → Jigs Release, Steel Pipe Retracts from Test Heads → Pipe Discharge from Testing Machine (signal output for untest-passed pipes) → Residual-water Blowing-off → Discharge onto Unloading Rack → Next Cycle
Why Choose This Hydro Testing Machine?
Selecting the proper pipe hydrostatic testing machine involves more than simply satisfying pressure requirements. Stable performance, dependable operation and low maintenance directly affect production efficiency and operational costs.
