Before you can start rolling, you will need to select the right expander for the job. Tube OD, and Wall/BWG will determine the size of the expander. However, there are some other factors to consider, such as tube projection, roll length, reach requirements, space constraints, and whether it’s minimum or average wall tubing.
In general, you want to roll to the lowest wall reduction possible where a tight tube to tube sheet joint can be achieved. The harder the material the less wall reduction required to obtain a tube joint. You should always consult the manufacturer of the heat transfer vessel for specific information before undertaking any maintenance procedures.
Tube pullers grip and pull the tube out from the tube sheet. There are a variety of tube removal tools available and each one has a specific use. Review the quick guide below to make sure you select the right tool for the job.
Getting the right tools for your application is critical in order to complete the job right the first time. One of the most overlooked factors when ordering tooling, is determining whether you have minimum wall or average wall tubing.
When installing heat exchanger tubes, it can be difficult to guide them through the support sheets or baffle holes. The best way to overcome this challenge is to use Elliott Tube Pilots.
