Fabricant chinois de machines d'essais hydrostatiques pour tubes de cuvelage et de production (OCTG), unité d'essai de pression pour tubes en acier au carbone et en acier allié

Présentation générale

GH Petro is a professional OCTG Casing Tubing Hydrostatic Test Machine Manufacturer in China.Our factory’s hydrostatic testers are designed in accordance with API 5CT and other relevant standards and our products adopt a large radial gap sealing/end-face sealing method to seal both ends of steel pipes according to customers’request.

High-pressure water is injected into the pipes, and the pressure is maintained for a specified time to check for leakage.All test results are automatically saved in the database to realize full traceability of inspection data.

Hydrostatic tester types：single-station hydrostatic testing machine,double-station hydrostatic testing machine and multi-station hydrostatic testing machine.

GH pipe hydrostatic testers are engineered for seamless, ERW, LSAW and SSAW steel pipes, as well as stainless steel and alloy steel pipes. Each unit is custom-engineered based on your pipe specifications, including outer diameter, wall thickness, pipe length, required test pressure and production throughput.

Featuring a heavy-duty hydraulic frame, PLC automatic control system and high-pressure plunger pump, the equipment delivers stable pressurization, dependable sealing and high operational efficiency for continuous industrial production.

Déroulement du processus

L'essai de pression hydraulique comprend trois étapes : le rinçage des canalisations, l'essai de pression et la vidange de l'eau, ainsi que ils sont courir les uns après les autres comme suit :

(Quai de chargement → Butée de tuyau et distributeur) → Inclinaison du tuyau → Alignement et rinçage → Station d’attente → Introduction dans la machine d’essai → Serrage par gabarits → Avance des têtes d’essai aux deux extrémités jusqu’à leur position → Pré-étanchéification → Remplissage d’eau et purge → Augmentation de la pression dans le corps du tuyau → Maintien de la pression → Décharge séquentielle de la pression → Les deuxtêtes d’essai aux deux extrémités se rétractent → Libération des gabarits, le tuyau en acier se retire des têtes d’essai → Évacuation du tuyau de la machine d’essai (émission d’un signal pour les tuyaux n’ayant pas passé l’essai) → Purge de l’eau résiduelle → Déchargement sur le rack de déchargement → Cycle suivant

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.
