It is obvious that tube removal is an intricate process that normally involves pulling out tubes and tube stubs as well as cutting of tubes. Since the tubes of heat exchangers and steam condensers corrode and suffer because of long-term use, the tubes require replacement at regular intervals that can help the unit as well as the operator to keep it working at its full capacity. The companies have developed a rich line up of tube pulling machines.The machines are able to successfully pull out tubes that are deteriorated and help in the healthy operation of plants and factories. The tubes, being used at various places, play an important role and hence one must focus on the quality as well as maintenance of the tubes.
The oldest method of removing tubes from a tube sheet is to manually pull them out by using a suitable tool after they are crushed with a hammer. This kind of method will take a lot of time and manpower because each tube requires to be pulled out individually. Tube removal tools are discussed below:
Continuous hydraulic tube puller
In this method, tubes are pulled continuously through the gun, and both methods pneumatic power packs and electric packs are utilized. In power, pack pressure is allowed up to 350 bar working pressure.
- The hydraulic tube pulling gun is in commune with power pack through 9v DC remote control thus ensuring safety and eliminating the requirement of electrical cord between gun and pump.
- It is available in electric TTP system or pneumatic PPP system for perils, hazardous explosive working surroundings.
- The microprocessor is controlled on power pack and hydraulic tube pulling gun ensuring trouble-free
- The tube can be removed without any damage to the tube
- Ease of operation and low setup time and smooth tube removal.
- High speed automatic cycling and high power for highest speed of tube puller.
- Available with auto switch over from low-pressure, high flow to high-pressure, low flow on load and when the load is released again back to a low-pressure, high flow.
- It has automatic slow start feature to diminish the risk of breaking tube puller, and it conserves consumables.
- Fitted with compact power pack and hydraulic tube pilling gun.
- It has stainless steel body of power pack for longer corrosion free life
- Low maintenance cost
- It is mounted on four-wheelers for easy handling and is portable with handle.
- It removes tube without causing damage to the tube
- Ease of operation and low set up time.
- Only one man is needed for operation.
- Considerable saving of time and money in comparison to conventional systems.
- Contains interchangeable pulling guns with same power pack.
- It has the compact design of gun and power pack.
- Have 15ton gun and 30-ton
- 24 VDC control electric power pack
- It pulls up to 3 OD tubes continuously and pills up to 4 OD stub
