Kufunika kopanga chitoliro cholumikizidwa ndi msoko wautali pansi pa nthaka

Pakadali pano, mapaipi amagwiritsidwa ntchito makamaka ponyamula mafuta ndi gasi mtunda wautali. Mapaipi achitsulo a mapaipi omwe amagwiritsidwa ntchito m'mapaipi akutali makamaka ndi awa:mapaipi achitsulo ozungulira ozungulira ozungulirandi mapaipi achitsulo olumikizidwa molunjika okhala ndi mbali ziwiri. Chifukwa chitoliro cholumikizidwa chozungulira chozungulira chimapangidwa ndi chitsulo chodulidwa ndipo makulidwe ake a khoma ndi ochepa, kusintha kwa chitsulo kumachepetsedwa ndi kutentha kwa zinthuzo. Kuphatikiza apo, pali zofooka zina zosagonjetseka za chitoliro cholumikizidwa chozungulira chozungulira, monga weld yayitali, kupsinjika kwakukulu kotsalira komanso kudalirika kochepa kwa weld. Ndi kufunikira kowonjezereka kwa mapaipi achitsulo otumizira mafuta ndi gasi, sagwiritsidwanso ntchito m'malo okhala anthu ambiri komanso madera omwe ali ndi zofunikira kwambiri zodalirika, ndipomapaipi owongoka olumikizidwa molunjika a mainchesi akulupang'onopang'ono akulowa m'malo mwa mapaipi ozungulira.

Posachedwapa, China ikufulumizitsa chitukuko cha mafuta ndi gasi ku East China Sea. Chifukwa cha chitukuko cha kufalikira kwa mafuta m'madzi akuya, payipi yomwe ili pansi pa nyanja imakhudzidwa ndi mphamvu zophatikizana za kupanikizika, mphamvu yogundana ndi mphamvu yopindika, ndipo vuto la kuphwanyika likuwonekerabe, lomwe ndi mgwirizano wofooka wa payipi yolumikizidwa mozungulira. Pofuna kukweza mphamvu yoyendera payipi ndikuwonetsetsa kuti payipi ya pansi pamadzi ikupita kukhoma lolimba, payipi ya pansi pamadzi nthawi zambiri imagwiritsa ntchito payipi yolumikizidwa molunjika. Chifukwa chake, poyerekeza ndi payipi yolumikizidwa mozungulira, payipi yolumikizidwa molunjika imakhala ndi kulondola kwakukulu komanso kuwotcherera kosavuta kukonza, kotero kuchokera pankhaniyi, payipi yolumikizidwa molunjika ndiyonso chisankho choyamba.

Makina, zomangamanga, makampani opanga mankhwala ndi mafakitale ena amafunika mapaipi owongoka. Pakadali pano, dzenje lamkati la mpando wa valavu limapangidwa pambuyo popangira mumakampani opanga makina, zomwe zimatenga nthawi yambiri, zimawononga ndalama zambiri komanso zimawononga zinthu. Ngati chitoliro chowongoka chokhala ndi makoma okhuthala chikugwiritsidwa ntchito, chidzakhala chotsika mtengo kwambiri. Kuphatikiza apo, chifukwa cha zofunikira za makina oletsa kuphwanyika, mapaipi owongoka okha ndi omwe amagwiritsidwa ntchito pomanga mapaipi; chitoliro chowongoka chikuyembekezekanso kugwiritsidwa ntchito pa mapaipi a mankhwala.
