Calculation System Overview
Technical calculations for polyethylene pipes
Burial Strength Calculation
Simply select the diameter and length, and the deflection ratio, vertical earth pressure, etc. are automatically calculated.
This is a calculation program to diagnose problems with pipe strength, etc.

Technical calculations for pipe heat insulators
Calculation of temperature drop of fluid transported in a pipe
This program calculates how many degrees Celsius the inlet fluid temperature of a pipe will be at the outlet.
Calculation of static fluid temperature drop in a pipe
This program calculates the fluid temperature after a certain time when the fluid is at rest in a pipe.
Calculation of thermal insulation surface temperature and condensation limit humidity
This program calculates how many degrees Celsius the surface temperature of the thermal insulation will be when it is installed.
Freezing Time Calculation by Heat Insulation Material
This program calculates the time required for the fluid in a pipe to freeze when thermal insulation is installed.
