Payipu ya Casing

Payipu ya casing ey’ekyumaye nnyiriri y’enzimba ekwata ekituli ky’oluzzi nga kiggule era n’ewa ekiziyiza eky’okusiba seminti n’okwawula mu bitundu-okulonda kwo okw’ekisenge kikwata butereevu ku mabbali g’okugwa/okubutuka n’obulungi bw’oluzzi obw’ekiseera ekiwanvu-.Octal Pipe egaba payipu y’omusulo ey’omutindo ogwa waggulu-ekoleddwa mu ngeri enkakali ne API 5CT ne ISO 11960 omutindo, nga bikwata ku mutindo gw’ebyuma ebijjuvu n’...ebika by’okuyungibwaokutuukiriza ebisaanyizo bya pulojekiti mu nsi yonna.

Bw’oba ​​olonda casing y’oluzzi olupya, ebibuuzo ebisooka buli yinginiya w’okusima oba okugula ebintu by’alina okuddibwamu byangu naye bikulu nnyo:

• Casing eno esobola okukwata obuziba bw’oluzzi lwange, pressure profile, n’omugugu gw’okugwa?
• Omugabi agaba obubonero obutebenkevu (obutasukka-ebintu ebinyigirizibwa)?
• Obuwuzi bwesigika ekimala ku pulogulaamu yange ey’obuzito bw’ebitosi ne torque?
• Basobola okutuusa sayizi entuufu n’obuwanvu obwetaagisa mu nteekateeka yange ey’okudduka?
• Waliwo okulondoola okujjuvu n’okulondoola omutindo emabega wa buli kiyungo?

Octal Pipe egaba API 5CT casing ezimbiddwa okwetoloola ebyetaago bino ebya pulojekiti entuufu-si API minimums zokka.
Buli kiyungo kye tutuusa kirina kemiko efugibwa, eby’ebyuma ebikakasiddwa, okwekebejja ku ddaala lya PSL2-, n’okutebenkera kw’okulongoosa okw’ebbugumu okuwandiikiddwa okukakasa okugwa, okubutuka, n’okukola kw’okusika okuteeberezebwa mu luzzi.

Oyagala kulaba engeri payipu zino gye zipakibwamu mu butuufu, okutikkibwa n’okusindikibwa ku nzizi ne payipu entuufu?
