- Po'lat quvurlarning bosim ko'tarish qobiliyati va devor qalinligini hisoblash formulasi:
Bosim=(devor qalinligi × 2 × po'lat quvur materialining kuchlanish kuchi) / (tashqi diametr * koeffitsient)
Yuqorida aytib o'tilgan po'lat quvur bosim koeffitsienti qat'iy qiymat emas, u mis quvurining haqiqiy bosim ko'tarish qobiliyatiga qarab o'zgaradi. Quyida po'lat quvur bosim koeffitsientining ta'rifi diapazoni keltirilgan:
Qachon bosim P<7Mpa, the coefficient is S=8;
Qachon 7
When the pressure P>17,5, koeffitsienti S =4.
