Kazi za couplings
Couplings na mizizi ni vitu muhimu katika tasnia ya mafuta na gesi, ikitumikia kuunganisha urefu wa casing au bomba za bomba pamoja, ambazo hufanywa kutoka kwa vifaa ambavyo vinafanana au kuzidi daraja la casing au neli.

Viungo vya PUP
Pamoja ya PUP ni aina ya casing ya urefu mfupi na neli, ambayo hutumiwa kurekebisha urefu wa kamba ya jumla. Viungo hivi vya PUP kawaida hutiwa kwenye ncha zote mbili na huja kwa urefu tofauti ili kuwezesha marekebisho muhimu katika kisima.
Urefu wa kawaida: 1ft, 2ft, 3ft, 4ft, 6ft, 8ft, 10ft, nk ..
Daraja: J55, K55, N80, L80, P110, nk.
