Mapepa akapetwa kaviriinovakwa neyako yakazvimirira maWels kuti iite yakasimba uye yakavimbika kubatana pakati pezvidimbu zvikamu. Iyi yakapetwa kaviri nzira inovimbisa kuti pombi inogona kutsungirira kushushikana uye kutambudzika kunogona kusangana panguva yekushanda, kuiita sarudzo yakavimbika yezvekunyorera iko kutadza haisi sarudzo.

Chimwe chezvakanakisa zvakanakira mapepa maviri-akakwana kugona kwavo kubata nzvimbo dzakakwirira-dzvinyiriro. Maitiro akapetwa kaviri anogadzira kubatana kusanzwisisika uye kwakasimba kubatana kwezvikamu zvePIPE, kuvimba kuti zvinogona kutsungirira kumanikidzwa kwemukati pasina njodzi yekukora kana kutadza. Izvi zvinovaita kuti vakunde kuti zvikumbiro zvakadai semafuta negesi pipi, apo kutendeseka kwePippeline system kunoshoropodza nekubudirira kwekuchengetedza.
