Safety: Handle Corrosive Acids and Caustics Safely

Back to Basics: Selecting Tube Inserts for Shell-and-Tube Heat Exchangers
A tube insert modifies flow stream characteristics to enhance heat transfer. Here's how to choose the optimal insert to meet process requirements.

Understand the corrosivity hazards of acids and caustics, and follow these guidelines to manage those hazards through inherently safer design, engineering and administrative controls, and personal protective equipment.
