Features
The subsea hydraulic bolt tensioner embodies the characteristics of rapidity and efficiency, enhancing the reliability of equipment in deep-sea operations, improving the safety of the equipment, and significantly increasing efficiency.
Ultra-high pressure manual hydraulic pumps, ultra-high pressure pneumatic hydraulic pumps, and ultra-high pressure electric hydraulic pumps can all be used in conjunction.
The subsea hydraulic bolt tensioner embodies the characteristics of rapidity and efficiency, enhancing the reliability of equipment in deep-sea operations, improving the safety of the equipment, and significantly increasing efficiency.
Application scenario: In the development of deep-sea oil and gas fields, the laying and connection of submarine pipelines require high-precision and high-strength equipment.
The function of subsea tensioners: Large tonnage high-pressure hydraulic cylinders are used to drive subsea pipeline laying machines (PLET/PLEM) and connectors, ensuring precise docking and sealing of pipelines in high-pressure and low-temperature environments.
Case: In deep-sea oil and gas fields in the North Sea and Gulf of Mexico, hydraulic cylinders are used to install and maintain subsea pipelines, ensuring the safety and reliability of oil and gas transportation.
