ʻO Valve ka mea kumu o ka ʻōnaehana pipeline a noho i kahi kūlana koʻikoʻi i ka ʻoihana mīkini.Loaʻa iā ia ka laulā o nā noi.He ʻāpana pono ia i ka ʻenehana hoʻouna ʻana o ka wai, wai a me ke kinoea.He ʻāpana mīkini koʻikoʻi ia i ka ʻoihana mana nuklea, ʻoihana petrochemical, lako wai a me ka hoʻomehana, a me nā kīwila.ʻO ka ʻikepili o ka ʻoihana valve honua i nā makahiki ʻekolu i hala iho nei, ʻo 19.5-20 biliona ka nui o ka hopena o ka honua holoʻokoʻa, a piʻi mau ka waiwai o ka huahana.I ka makahiki 2019, ʻo US $64 biliona ka waiwai o ka pahu valve honua, i ka makahiki 2020, ʻo US $ 73.2 biliona ke kumukūʻai o ka pahu valve honua, a i ka makahiki 2021, ʻo US $ 76 biliona.I nā makahiki ʻelua i hala iho nei, ma muli o ka piʻi ʻana o ke ao holoʻokoʻa, ua piʻi nui ka waiwai o ka puka valve.Ma hope o ka unuhi ʻana i ka inflation, ua mau ke kumukūʻai puka valve honua ma kahi o 3%.Ua manaʻo ʻia ma ka makahiki 2025, e piʻi ke kumukūʻai o ka pahu valve honua ma kahi o US $90 biliona.
I ka ʻoihana valve honua, ʻo ʻAmelika Hui Pū ʻIa, Kelemānia, Iapana, Palani a me Taiwan, ʻo Kina i ka echelon mua o ka ikaika piha, a noho kā lākou mau kiwi i ka mākeke kiʻekiʻe o ka ʻoihana.
Mai ka 1980s, ua hoʻoneʻe mālie ʻo ʻAmelika Hui Pū ʻIa, Iapana, Kelemānia, South Korea a me nā ʻāina ʻē aʻe i nā ʻoihana waena a haʻahaʻa i nā ʻāina ulu.ʻO Kina ka ʻāina me ka ʻoihana ʻoi loa a me ka wikiwiki o ka ulu ʻana.
I kēia manawa, ua lilo ia i ʻāina ʻoihana valve nui loa ma ka honua e pili ana i ka hana valve a me ka lawe ʻana aku, a ke neʻe nei i kahi ʻāina valve ikaika.
