Specifies the qualified stress for joints, bends, and tees.

Typical units (depending on your unit system):

  • lb/in2

  • KPa

  • N/mm²

A qualified stress, Qs, provided by the manufacturer is defined as:

Pq is the qualified pressure;

D is the average diameter of the pipe;

tr is the average reinforced wall thickness of the pipe.

The qualified stress, sqs, for fittings is calculated as:

  • CAESAR II does not require qualified stress Qs for plain pipe. Qs for pipe = hl(2:1), and hl(2:1) is required input for plain pipe.

  • You must enter qualified stress Qs for joints, bends and tees even if these fitting are not in the piping model. You can type positive values (1000.0 for Qs and 1.0 for r, for example) to pass the Error Checker.
