Shell & Tube Heat Exchangers

Altex is High-Spec Shell & Tube

Heat exchangers aren’t getting any easier. Shell and tube heat exchanger regulations, specifications, and technical requirements are ever-growing in scope and complexity and require significant engineering horsepower to transform the documentation into a fabricated shell & tube heat exchanger.

Big and Ugly

Large-diameter, high-pressure, heavy, challenging metallurgy, and/or high-spec shell and tube heat exchangers – this is our bread and butter.

To chew through this type of work you need serious engineering and technical horsepower, which is why Altex has over a dozen Professional Engineers in-house for your shell and tube heat exchanger!

You also need technical experts throughout the organization to drive projects successfully from manufacturing to shell and tube heat exchanger maintenance.
