Hydraulic and Instrumentation — Material Recommendation

Is your current tubing material the right fit? In hydraulic and instrumentation lines, the wrong grade can mean leaks, downtime, and safety risks — while an advanced Alleima alloy can eliminate those failure modes entirely.

This tool helps you identify a better-suited Alleima grade for your specific application based on the operating environment and the failures you’re seeing today.

A few questions is all it takes. Pick your application, your current material, and how it has been failing — we’ll suggest a grade designed to remove those risks.

Hydraulic and Instrumentation

Select the application where the tubes are installed.

Application

Select the specific application. This determines the operating environment and risk profile used in the recommendation.

Sub Application

Select the sub application to further refine the operating environment.

Current Material

Tell us about the material currently used in your tubes and how it has been failing.

Material Grade

Select the grade currently in use. The recommendation is based on this selection.

Tube Dimensions

Select the tube outer diameter × wall thickness. If your exact dimension is not listed, pick the closest available option.

Main Failure Reason

Pick the failure mode that best matches what you typically see in this installation.

Losses Due to Failure

Approximate cost impact of a typical failure event (downtime, replacement, lost production combined).
