Ekuqaleni, ukuthuthwa kwamapayipi ukuthuthwa kwempahla noma izinto zokwakha ngepayipi. Izinhlobo eziningi zamapayipi ensimbi zisetshenziselwa kabanzi amapayipi kumaphrojekthi amapayipi ahlukene namuhla. Ngeminyaka yawo-1860 njengoba ibhizinisi lamapayipi likhula, ukulawulwa kwekhwalithi yokwenziwa kwamapayipi kwaba yinto engokoqobo futhi ikhwalithi nohlobo lwensimbi lwamapayipi kwaba ngcono ukusuka kunsimbi ekhandiwe kuya kwensimbi. Ekuphileni kwethu kwansuku zonke, cishe wonke umuntu uyazi indawo yegalaji lendawo yangakubo; ikhaya lakho lingase lifudumale ngokufudumeza amafutha noma igesi yemvelo; futhi amakhaya amaningi asebenzisa igesi yemvelo ekuphekeni. Kodwa bewazi yini ukuthi le mikhiqizo - uphethiloli, uwoyela wokushisisa ekhaya, negesi yemvelo - ihamba amabanga amade isuka ezindaweni ezihluzwayo nasezimbonini zegesi yemvelo iye emiphakathini esizweni sonke ngamapayipi angaphansi komhlaba?
Njengoba kwaziwa yibo bonke, lolu xhaxha lwamapayipi lungamaqhawe angaculwa asekela indlela yethu yokuphila yansuku zonke ngokuhamba kwezinto ezifana namanzi, indle, uwoyela ongahluziwe kanye nemikhiqizo kaphethiloli kanye negesi yemvelo - ezikhathini eziningi ezifakwa ngaphansi kwemigwaqo yethu. Ipayipi lensimbi eliyindilinga liwuhlobo olujwayelekile lwepayipi elisetshenziswa kule migudu yenethiwekhi empilweni yangempela. Bahamba ngokuphepha ezindaweni ezingomakhelwane nasemiphakathini, benwebeka emapulazini, emahlathini, ezingwadule, nakuyo yonke indawo phakathi. Wona la mapayipi ahlinzeka ngophethiloli wokukhiqiza ugesi kanye nezakhiwo zokwakha umanyolo ukuze kwandiswe ukukhiqizwa kwezitshalo. Amapayipi aphinde aqoqe uwoyela ongahluziwe ezindaweni eziningi zasemakhaya ukuze awuhambise ezindaweni ezihluzwayo nasezimbonini zamakhemikhali ukuze bakhe yonke imikhiqizo evela ekwenziweni kwe-petroleum namakhemikhali e-petrochemicals.
Izintambo zokuqoqa uwoyela negesi amapayipi ensimbi athutha uwoyela noma igesi ukusuka endaweni yokukhiqiza ukuya endaweni yokugcina noma ipayipi elikhulu. Emakethe yensimbi, ipayipi lensimbi elifakwe emanzini ashisayo liwuhlobo oludumile lwepayipi elisetshenziswa ezimweni ezimbi kakhulu ezifana nezindawo ezonakalisayo, amazinga okushisa aphansi naphezulu, ukucindezela okuphezulu kanye nenkonzo emuncu. Igesi yemvelo ithuthwa ngohlelo lwamapayipi okudlulisela, olwakhiwe ngamapayipi ensimbi anobubanzi obukhulu. Ipayipi elivunguzayo elivunguzayo lisetshenziselwa ukwakhiwa kwamapayipi amapayipi ahamba amabanga amade ahambisa igesi.
Njengomkhiqizi ochwepheshile wamapayipi ensimbi e-China, sihlala sizibophezele ekubambeni iqhaza elikhulu embonini ye-petroleum ehlinzeka ngezinto zokuhamba eziphephile, ezinokwethenjelwa nezongayo. Ubuchwepheshe buyaqhubeka nokwenza amapayipi angcono ensimbi engcono, bathole izindlela ezingcono zokufaka ipayipi emhlabathini, futhi bahlale behlaziya isimo salo uma seliphansi. Ngesikhathi esifanayo, imithetho yokuphepha yamapayipi isiphelele kakhulu, iqhutshwa ukuqonda okungcono kwezinto ezitholakalayo kanye namasu angcono okusebenza nokugcina amapayipi.
