Mtundu wa Taper Annular BOP
Mbali
1) Gwiritsani ntchito tapered packing unit ndi mutu wa BOP ndipo thupi limalumikizidwa ndi midadada ya latch.
2) Chisindikizo champhamvu cha BOP chimatenga mphete yosindikizira ngati milomo kuti muchepetse kuvala kwa mphete yosindikizira ndikuwonetsetsa kusindikizidwa kodalirika.
3) Pistoni yokha ndi gawo lonyamula katundu ndizomwe zimasuntha, zomwe zimachepetsa bwino malo ovala ndikufupikitsa nthawi yokonza ndi kukonza.
4) Zida zonse zachitsulo zomwe zimakumana ndi madzi am'madzi ziyenera kukwaniritsa zofunikira za NACE MR 0175 pa ntchito yowawasa.
5) Kupanikizika kwabwino kumathandizira kusindikiza.

Izi zimakhala ndi chosindikizira cha milomo chokhala ndi mphamvu yodzisindikiza yokha kuti ikhale yodalirika. Ili ndi bore mu pisitoni poyesa sitiroko kuyeza moyo wa rabala. Kulumikizana kwa mbale ya claw kumatsimikizira kulumikizana kodalirika, ngakhale kupsinjika kwa chipolopolo ndikuyika kosavuta. Ma pistoni ake apamwamba ndi ooneka ngati cone, zomwe zimapangitsa kuti pakhale kunja kwa kunja kwake. Kuphatikiza apo, pamwamba pa mikangano imakhala ndi mbale yotsimikizira ma abrasion kuti iteteze mutu ndipo ndiyosavuta kuyisintha.
