Hydraulic Casing Extraction System & Key Features
Hydraulic Casing Extraction Configuration
The TD-EQP-EXT-002 is a hydraulic casing extractor designed for pulling drilling casings. Its published specifications include a rated pulling force of 800 kN and a rated hydraulic pressure of 28 MPa. Equipment suitability should be evaluated according to the casing configuration, expected extraction resistance, and site operating conditions.
800 kN Rated Pulling Force
The equipment provides a rated pulling force of 800 kN, compared with 600 kN for the TD-EQP-EXT-001 model. This difference allows buyers to compare the two models according to their required pulling force. Actual extraction performance depends on casing characteristics, ground resistance, and the operating arrangement.
50–168 mm Casing Diameter Range
The specified casing diameter range is 50–168 mm, with a published casing extraction depth range of 20–60 m. These parameters provide a starting point for equipment selection. Buyers should confirm casing dimensions, installation depth, and anticipated extraction resistance before choosing a model.
500 mm Hydraulic Cylinder Stroke
The hydraulic extraction system has a specified cylinder stroke of 500 mm and an extraction speed of 1,440 mm/min. These values describe the published operating parameters of the equipment. The cylinder stroke should not be confused with total casing extraction depth, and the stated extraction speed does not represent a guaranteed overall job completion rate.
7.5 kW Hydraulic Power Unit
The hydraulic power unit is equipped with a 7.5 kW motor and has published dimensions of 750 × 650 × 450 mm. The upper assembly has a listed weight of 160 kg, excluding hydraulic oil. These specifications can help buyers assess equipment arrangement and handling requirements, while the total equipment weight, electrical supply details, and complete installation dimensions require separate confirmation.
Casing Extraction Applications & Equipment Selection
Drilling Casing Extraction
The TD-EQP-EXT-002 is designed for extracting casings used in drilling operations. It has a specified casing diameter range of 50–168 mm, an extraction depth range of 20–60 m, and a rated pulling force of 800 kN. Equipment suitability should be assessed according to casing dimensions, expected extraction resistance, and drilling site conditions.
Casing Diameter and Pulling Force Selection
Casing diameter, installation depth, and expected extraction resistance are important considerations when selecting a hydraulic casing extractor. The TD-EQP-EXT-002 provides a higher rated pulling force than the 600 kN TD-EQP-EXT-001 model, while both models share the same published casing diameter and extraction depth ranges. Buyers should provide the actual casing specifications and available ground condition information to help determine which model is more appropriate.
Hydraulic Extraction and Site Arrangement
The equipment operates at a rated hydraulic pressure of 28 MPa and has a specified hydraulic cylinder stroke of 500 mm. Before selecting the extractor, buyers should review casing accessibility, available working space, equipment positioning, and the requirements for supporting and securing the equipment during operation. Detailed installation and mounting arrangements should be confirmed for the intended project.
Hydraulic Power Supply and Equipment Configuration
The TD-EQP-EXT-002 uses a hydraulic power unit equipped with a 7.5 kW motor. The published power unit dimensions are 750 × 650 × 450 mm, and the listed upper assembly weight is 160 kg, excluding hydraulic oil. Buyers should confirm the available electrical supply, hydraulic connections, equipment handling requirements, and proposed supply configuration before ordering.
Frequently Asked Questions
01What casing diameters and extraction depths does the TD-EQP-EXT-002 support?
The TD-EQP-EXT-002 has a specified casing diameter range of 50–168 mm and an extraction depth range of 20–60 m. Actual extraction capability depends on casing dimensions, ground resistance, installation conditions, and the equipment configuration. The published ranges should be evaluated against the requirements of each drilling project.
02What is the difference between the 800 kN and 600 kN hydraulic casing extractors?
The TD-EQP-EXT-002 has a rated pulling force of 800 kN and a 7.5 kW motor, compared with 600 kN and 5.5 kW for the TD-EQP-EXT-001. Both models share the same published casing diameter range of 50–168 mm and extraction depth range of 20–60 m. The appropriate model should be selected according to the expected extraction resistance and project requirements rather than rated pulling force alone.
03What are the hydraulic pressure, cylinder stroke, and extraction speed specifications?
The TD-EQP-EXT-002 has a rated hydraulic pressure of 28 MPa, a hydraulic cylinder stroke of 500 mm, and a specified extraction speed of 1,440 mm/min. The cylinder stroke refers to the movement available during an extraction stroke, not the total casing extraction depth. The published extraction speed is an equipment specification and does not represent a guaranteed overall job completion rate.
04What power supply and installation details should be confirmed before using the TD-EQP-EXT-002?
The TD-EQP-EXT-002 uses a hydraulic power unit equipped with a 7.5 kW motor. The published power unit dimensions are 750 × 650 × 450 mm, and the upper assembly has a listed weight of 160 kg, excluding hydraulic oil. Before installation, buyers should confirm the electrical supply requirements, hydraulic connections, equipment positioning, available working space, and handling arrangements. The total equipment weight and detailed mounting requirements should be confirmed separately.
05What information should I provide when requesting a quotation for the TD-EQP-EXT-002?
Please provide the casing outside diameter, casing length or installed depth, casing material and connection details, expected ground conditions, and any known extraction difficulties. Information about the available electrical supply, working space, and intended equipment arrangement is also helpful. If specific hydraulic connections, accessories, or handling equipment are required, please include these requirements so that equipment suitability and the proposed supply configuration can be reviewed.
