Automatic tube pullers or Runpullers are specific devices for removing tubes from heat exchangers, boilers, or condensers. When the tubes of heat exchanger, boiler or condenser have been used for several years, or have started to leak, the consequence is reducing the overall efficiency. Therefore, the damaged or precipitated tubes should be removed by Automatic tube pullers.

For pulling process the maintenance operator prepares the Automatic tube puller by connecting the hydraulic power source and position it to the specific tube. The precise and safety of this stabilization is important. After inserting the puller into the tube, the device uses expandable jaws which fit inside the tube tightly and grip the tube then pull the tube out of the tube sheet.

A hydraulic pump will generate the necessary pressure to power the Automatic tube puller. This hydraulic pressure forces the gun to pull the tube out of the tube sheet. Once the tube is completely removed, the extracted tube is then set aside for inspection or disposal. This process will continue automatically.

Advantages of Automatic tube puller:

• Accurate performance
• High efficiency
• Reduce down time
• Continuous high speed tube removal
• Available with both electric or pneumatic drive

Only Puller function:

1. Preparation: the operator prepares the tube puller by attaching the device to the specific tube which need to be extracted.
2. Operation: the semi-automatic tube puller uses a hydraulic power to grip and pull the tube.
3. Extraction: as the puller operates, theOnly puller extracts the tube from the heat exchanger, boiler or condenser.
4. Completion: once the tube is completely removed, the run puller then repositioned to extract other tubes.

Advantages:

• Enhanced efficiency
• Ease of use
• Accurate performance
• Compact design

The Grippul/Attaching hydraulic stub puller is a specific device for pulling tubes. This device is particularly useful in re-tubing the U-type heat exchangers.

Steps for re-tubing by using Grippul:

1. Using a tube cutter to cut the end of the tube connected to the tube sheet.
2. Inserting the Grippul into the remaining tube. This attachment is secure to ensure the tube pulling out completely.
3. Throw the pulled tube away, and attach to another tube in order to complete the process.

By cutting the tube’s end and utilizing the Grippul device, the maintenance process becomes faster and easier.

Advantages of using the device:

• Increasing efficiency
• Ease of use
• Safety
• Robust construction
• Customizable

Tube bundle lifting machine

A tube bundle lifter is a specialized device which has designed for lifting and displacing tube bundles in shell and tube heat exchangers. These lifters are essential for handling tube bundles during repair and maintenance operations.

Increase safety, security and can be used both within the plant and during the production of heat exchangers. By lifting the tube bundle easily and safely, the Bundle lifter eliminates the risk of destroying the tubes.

Performance of the Tube bundle lifter

Tube bundle lifting machine is a device designed to lift and handle tube bundles for industrial applicaxtions.it applies an extensive force throughout the tube bundle which prevents the tube bundle from buckling compared to traditional methods.

Features and Functions:

• Robust and Reliable Construction
• Precision Handling
• Versatile and Customizable
• Ease of Mobility
• Precision Handling
• Enhancing Safety and Efficiency
• Compact Design

Tube bundle rollers  are hydraulic devices used to wash tube bundles during services. Tube bundle rollers (TBR) consists of one driven roller unit and one non-driven roller unit.

 Based on tube sheet diameter, the distance between rollers can be adjusted. The velocity of rollers can also be controlled for washing during maintenance. The rollers are well heat treated and coated, resistant to corrosion and welding during services.

And can be used in washing centers of refineries for tube bundle washing and also welding too.

Tube bundle roller is a device with high efficiency used for washing and giving service to heat exchangers. While this innovative design proved incredibly successful at meeting our customers’ needs, we’ve now completed the overall design for our  TBR.

Tube bundle roller performance

Tube bundle rollers are designed for the rotation of tube bundles, allowing operators to clean 100% of the shell side. Sold as a set, the TBR consists of one driven roller unit and one non-driven roller unit. The system is hydraulically driven from the cab of an automated bundle cleaner.

Advantages of tube bundle roller

• Enhanced Efficiency
• Reduced Labor
• Safety Improvement
• Precision Handling
• Versatility
• Cost Savings
• Ease of Use
• Durability

overall, tube bundle rollers are valuable tools that enhance the maintenance process of tube bundles in heat exchangers and related equipment, offering significant benefits in terms of efficiency, safety, and cost-effectiveness.

A tube bundle extractor ( tube bundle puller ) facilitates removing tube bundles from heat exchangers, boilers, or other process equipment. It grips and pulls tube bundle from its entire shell. Based on the tube bundle weight and its length, various extractors can be used.

Applications

Tube bundle pullers are widely used in industries where shell and tube heat exchangers are common, including:

• Petrochemical Plants: For maintenance of heat exchangers used in refining processes.
• Power Plants: In the maintenance of condensers and heat exchangers involved in power generation.
• Chemical Plants: For various process heat exchangers.

Operation

Using a Tube bundle puller typically involves the following steps:

1. Preparation: Ensuring the heat exchanger is properly shut down and depressurized.
2. Attachment: Securing the extractor to the tube bundle and the heat exchanger shell.
3. Extraction: Using the tube bundle puller to carefully pull the bundle out of the shell.
4. Maintenance: Performing the necessary cleaning, inspection, and repair work on the bundle.
5. Reinsertion: Using the tube bundle puller to carefully reinsert the bundle into the shell.

Tube bundle pullers are critical tools for maintaining the efficiency and reliability of heat exchangers, ensuring that industrial processes run smoothly and safely.
