Apvalks
Apvalks ir liela diametra caurule, kas kalpo kā konstruktīvs aizturs naftas un gāzes urbumu sienām vai urbuma urbumam. To ievieto akas urbumā un iecementē vietā, lai aizsargātu gan pazemes veidojumus, gan urbuma urbumu no sabrukšanas un ļaut urbšanas šķidrumam cirkulēt un veikt ekstrakciju.Tērauda korpusa caurulēm ir gluda siena un minimālā tecēšanas robeža 35 000 psi.
Akas korpuss kalpo arī sānu sienai.Standarti un tehniskie nosacījumi piegādei: API Spec 5CT ISO13680 Pakāpe: J55, K55, N80-1, N80-Q, L80-1, L80-9Cr, L80-13Cr, C95, P110.Protektora veidi: NUE, EUE, VAM, STC, LTC, BTC, speciālais klīrenss, XC, VAM TOP, NEW VAM.
Eļļas apvalka caurule: Apvalki tiek izmantoti akas sienas vai lejas cauruma nostiprināšanai, kuriem ir plašs diametrs, ko var iedalīt vadītāju apvalkos, tehniskajos apvalkos un eļļas apvalkos.
Izmantošana: Akas apvalks kalpo arī sānu sienai.
