Tube cleaning is a necessary part of any vessel maintenance process. Depending on the application, water, gases, and other caustic chemicals can be run through the unit. Overtime, these compounds cause deposit build-up inside of the tubes, resulting in a loss in operating efficiency.
To get the best performance out of a vessel it’s important that it maintains necessary operating capacity. While there are several preventative maintenance procedures that can prolong the life of the vessel, eventually a decision on retubing or replacing the unit will need to be made.
When it comes to removing tubes, there are many different options to choose from. Hydraulic or automated pulling options can be a great way to speed up the job, reduce tube sheet damage, and improve operator ergonomics. However, before selecting a pulling package, it’s important to consider the vessel type, tube condition, and space constraints
In recent years, the use of exotic materials in heat exchanger tubing has become a lot more common. While these materials are great for working in tough conditions, they can have be very challenging to work with as they often require more tooling and job time. This is especially true in tube removal where pulling spears are used. Tapping spears have become an effective way to overcome many of these issues.
When needing to use and install mechanical tube plugs, having the correct tools for the job can make it easier and quicker to get the job. Below are step by step instructions to help overcome this challenge.
With a variety of boiler tube removal methods out there, it can be difficult to determine the best approach for your application. Depending on the amount of expansion, age of the tube, and other wear factors, tubes can be extremely difficult to get out. Removing tubes through a king hole can be an easier method of removal, especially for operators with varying experience levels.
The design of a chiller can pose some challenges when it comes to tube installation and maintenance. From the center tube sheet to tube enhancements, special considerations need to be made when choosing the correct tooling for the job.
Elliott Tool Technologies, a USA based tube tool manufacturer, announced the launch of a newly redesigned Grooving & Serrating tool. Equipped with a reusable wear pad the new mandrel design allows for metal chips to escape easily, reducing damage to the mandrel and tube sheet hole.
Training programs can benefit to all organizations, especially, those in competitive markets. From improving operator retention, boosting productivity, and cutting job costs, training is a great investment to ensure your staff is up to date on all the latest industry practices.
Elliott Tool Technologies, a USA based tube tool manufacturer, announced the launch of a new condenser expander collar design. The air cooler collar ring is designed to prevent costly damage to the plug hole threads and reduce the pressure put on the header box face.
