- Formula tal-kalkolu tal-kapaċità tal-ġarr tal-pressjoni tal-pajp tal-azzar u l-ħxuna tal-ħajt:
Pressjoni=(ħxuna tal-ħajt × 2 × qawwa tat-tensjoni tal-materjal tal-pajp tal-azzar) / (dijametru ta 'barra * koeffiċjent)
Il-koeffiċjent tal-pressjoni tal-pajp tal-azzar imsemmi hawn fuq mhuwiex valur fiss, jinbidel skont il-kapaċità attwali tal-pressjoni tal-pajp tar-ram. Din li ġejja hija l-firxa tad-definizzjoni tal-koeffiċjent tal-pressjoni tal-pajp tal-azzar:
Meta l-pressjoni P<7Mpa, the coefficient is S=8;
Meta 7
When the pressure P>17.5, il-koeffiċjent huwa S =4.
