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.

Fluxo do processo
O ensaio de pressão hidráulica compreende três etapas: lavagem da tubagem, ensaio de pressão e drenagem da água, e eles são correr em sequência da seguinte forma:
(Plataforma de carregamento → Batente e distribuidor de tubos) → Inclinação do tubo → Alinhamento e lavagem → Estação de espera → Alimentação na máquina de ensaio → Fixação por gabaritos → Avanço das cabeças de ensaio de ambas as extremidades para a posição → Pré-vedação → Enchimento com água e purga → Aumento da pressão no corpo do tubo → Manutenção da pressão → Alívio sequencial da pressão → Ambas ascabeças de ensaio em ambas as extremidades recuam → Libertação dos gabaritos, o tubo de aço recua das cabeças de ensaio → Descarga do tubo da máquina de ensaio (emissão de sinal para tubos que não passaram no ensaio) → Expulsão da água residual → Descarga na plataforma de descarga → Próximo ciclo
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.
