Use case

Technical pre-checks

Quickly visualize safe operating range before quotation, product selection, or design discussion.

Reference basis

Chart-backed values

Uses schedule, temperature, and material-based pressure tables with construction efficiency adjustment.

Output clarity

Engineer-friendly readings

Shows allowable pressure, applied pressure, utilisation percentage, and integrity status in one view.

Overview

Made for real piping conversations

This page is designed to help customers and engineers understand how pipe size, wall thickness, temperature, and construction type influence allowable working pressure.

Choose the grade

Select TP304, TP304L, or TP316 and compare how design strength changes with temperature.

Match the pipe size

Use standard NPS and DN combinations with OD and wall thickness linked to the selected schedule.

Adjust operating conditions

Slide temperature and applied pressure to see live pressure utilisation and operating status.

Interpret the result

Read safe, caution, or danger state immediately with MPa and kgf/cm² conversions included.

Engineering Notes

What this tool shows

Allowable pressure

The design limit changes with material, schedule, and temperature, so the result should always be read in context.

Construction efficiency

Switching from seamless to welded applies efficiency reduction, which directly lowers allowable pressure.

Practical use

Use this simulator as a pre-engineering and customer discussion aid, then validate final design through qualified review.
