Extractor eléctrico de haces tubulares
The electric heat exchanger bundle puller is a high-efficiency unit for petrochemical maintenance, driven by an electric motor and gear reducer with a sprocket-and-chain system to pull out and push in tube bundles. It supports manual, wired, and wireless remote operation, and its three-dimensional parametric structure ensures high strength, reliable performance, shorter shutdown time, and reduced labor costs.

Pulling force test & verification
To ensure the safety and reliability of our bundle extractor, we carried out full-load
pulling force tests on site.
Las principales condiciones de prueba fueron las siguientes:
Test
machine: Electric bundle extractor 65 T (QW65 series)
Test load: up to 70 T simulated
bundle weight
Duración de la prueba de extracción continua: 30 minutos
Result: no structural
deformation, normal hydraulic temperature, stable pressure without leakage.
The test
proves that the actual pulling capacity meets and exceeds the rated value, providing a safe
margin for field operation.
Preguntas frecuentes sobre el extractor eléctrico de haces tubulares
R: This equipment is mainly used for extracting and reinstalling tube bundles of shell-and-tube heat exchangers. It is suitable for major overhauls, shutdown maintenance, and emergency repair operations in refineries, chemical plants, LNG plants, and power plants. It is particularly well suited for projects with heavy tube bundles, severe fouling, limited on-site space, and strict requirements on minimizing downtime.
R: La selección del modelo depende principalmente de tres parámetros:
-
Maximum tube bundle weight (including fouling) – we recommend keeping a 20–30% safety margin.
-
Tube bundle length – standard handling range is aprox. 6–15 m; beyond this can be customized.
-
Site conditions – for example, whether there is heavy fouling and whether frequent continuous operation is required.
For instance, if the maximum tube bundle weight is 45 t, we recommend selecting the 65T model to ensure sufficient pulling force to deal with fouling and potential sticking.
R: For standard models, the rated pulling capacity is approximately 25–100 tons. Los parámetros típicos del haz tubular que puede manejar son:
-
Longitud del haz tubular: aprox. 6–15 m
-
Diámetro del haz tubular: aprox. 1000–2800 mm
The exact applicability should be checked against the actual heat exchanger drawings, and we can verify the parameters and recommend a suitable model based on your project data.
R:
-
A relatively flat and solid ground is required for placing the main unit and installing the rails.
-
The ground must have sufficient load-bearing capacity for the equipment weight and the tube bundle weight.
-
Reserve enough operating space in the length direction of the equipment so that the tube bundle can be fully extracted.
-
Confirm in advance the lifting conditions (crane capacity, lifting points, etc.).
If the site conditions are limited, we can provide simplified layout recommendations or customized solutions.
R: For standard models without special customization, the typical delivery time is
about 3–6 meses after order
confirmation.
If you require special pulling
capacity, extended rails, explosion-proof configuration, or other customized options,
the delivery time may be slightly longer. The exact schedule will be confirmed in our
official quotation and contract.
