Ngokuthuthuka okusheshayo kokwakhiwa komgwaqo omkhulu kanye nokwenyuka kwesidingo sebitumen, itiyela elinemigqomo selisetshenziswe kakhulu ngenxa yokuhamba kwalo amabanga amade nokugcinwa kwalo kalula. Ikakhulukazi, iningi lebitumen ephuma kwamanye amazwe esebenza kahle kakhulu esetshenziswa emigwaqweni enesivinini esiphezulu isesimweni esinemigqomo. Lesi sitshalo sokuncibilikisa itiyela esincibilika ngokushesha, sisuse imiphongolo ngokuhlanzekile, futhi sinqande itiyela ekugugeni siyadingeka.

Imishini yokuncibilikisa itiyela ekhiqizwa inkampani yethu ikakhulukazi iqukethe ibhokisi lokususa imiphongolo, umnyango wokuphakamisa ugesi, inqola yokulayisha itiyela, uhlelo lwe-trolley drive, uhlelo lokushisisa uwoyela oshisayo, uhlelo lokushisisa uwoyela esithandweni somlilo, iphampu yebitumen kanye nesistimu yepayipi, kanye nogesi. uhlelo lokulawula nezinye izingxenye.

Ibhokisi lihlukaniswe ngamakamelo aphezulu naphansi. Igumbi eliphezulu liyigumbi elikhipha umgqomo nelincibilikisa itiyela elinomgqomo. Ipayipi elishisisa uwoyela elishisayo elingezansi kanye negesi yokushisa ephezulu evela kubhayela kawoyela oshisayo ngokuhlanganyela ukushisa imiphongolo yebitumen ukuze kufezwe injongo yokukhipha itiyela emgqonyeni. Igumbi elingaphansi lisetshenziselwa ikakhulukazi ukuqhubeka nokushisa itiyela elikhishwe emgqonyeni. Ngemva kokuba izinga lokushisa lifinyelele izinga lokushisa elimpompa (ngaphezu kuka-110°C), iphampu yetiyela ingaqalwa ukupompa itiyela. Ohlelweni lwepayipi lebitumen, kufakwa isihlungi ukuze kukhishwe ngokuzenzakalelayo ukufakwa kwe-slag kwibitumen enemigqomo.

Imishini yokuncibilikisa itiyela ifakwe amabhakede ayindilinga ahlukaniswe ngokulinganayo ukuze kube lula ukuma okunembile kwebhakede ngalinye lapho lilayisha. Uhlelo lokudlulisela lunesibopho sokulayisha nokukhipha imiphongolo esindayo egcwele itiyela nemiphongolo engenalutho ngemva kokuhlanza nokuphuma ekamelweni eliphezulu lebhokisi. Inqubo yokusebenza yemishini iqedwa ngokusebenza endaweni eyodwa kukhabhinethi yokulawula kagesi, futhi ifakwe amathuluzi okuqapha adingekayo kanye namadivayisi okulawula ukuphepha.
