ʻO nā huahana paipu kila e pili ana i nā huahana pili i hana ʻia me nā paipu kila, ka mea i hoʻohana nui ʻia i nā mīkini hana, nā waiwai (scaffolding).paipu kila, lako wai, paipu kahe ea, paipu pale ahi), aila a me ke kinoea (paipu puna wai, paipu paipu), hale kila(pā kila), mana uila (paipu kila kalapona kūkulu), kaʻa a me ka kaʻa (paipu kila maʻemaʻe ʻole) a me nā ʻoihana ʻē aʻe, a he mau ʻano kila nui e pono ai.
1. ʻO ke kūkulu ʻana i ka pipeline ikehu a me ka ʻoihana waiwai i lilo i mea ikaika nui e hoʻohana ai i nā huahana paipu kila
Ma nā manaʻo alakaʻi o ka 13th Five-Year Plan for the Development of the Steel Pipe Industry i hoʻokuʻu ʻia e ka mokuʻāina, ʻo nā mīkini kūkulu hale, nā waiwai kūʻai aku, ka lawe ʻana aku a me ka aila a me ke kinoea ka mea nui i lalo o ka noi ʻana o nā huahana paipu kila ma Kina, e helu ana no 15%, 12.22%, 11.11% a me 10%.
Ua kōkua ka Urbanization a me ka "coal to gas" i ka ulu mau ʻana o ka mākeke kinoea noho.Hoʻokaʻawale ʻia ke kinoea i loko o ke kinoea, ke kinoea liquefied a me ke kinoea maoli, kahi e lawe ʻia ai ke kinoea kūlohelohe e ka pipeline.I kēia manawa, ʻo nā kūlanakauhale liʻiliʻi a liʻiliʻi o Kina, e hoʻohana ana i ka lanahu ma ke ʻano he kumu ikehu nui, he wahi nui e pani ai.Me ka paipai 'ana a me ke kākoʻo 'ana i ka "lanihu i ke kinoea" kulekele, ka unahi o Kina maoli kinoea makeke ua steadily mahuahua, a me ke kaʻina hana o superimposed urbanization ua accelerating, a me ka unahi o ka home noho kinoea market e mau ke ala.
No laila, ma ke ʻano o ka hoʻonui ʻia ʻana o ke kūlanakauhale, e ulu mau ana ka hoʻohana ʻana i ke kinoea kūlohelohe o Kina, e hoʻoulu i ka ulu wikiwiki o ka nui o ka pūnaewele pipeline kinoea, a pēlā e hoʻonui ai i ka makemake o ka ʻoihana huahana paipu kila.Wahi a ka ʻikepili, ʻo ka mileage o nā pipeline kinoea kūlohelohe ma Kina e hōʻea i 83400 mau kilomita i 2020, e piʻi ana i 3% makahiki ma ka makahiki, a ua manaʻo ʻia e hiki i 85500 mau kilomita i 2021.
Eia hou, e like me ka Papahana ʻumikūmāhā ʻelima makahiki, pono e lawe ʻia ke kūkulu hou ʻana o ka pipeline ma ke ʻano he papahana ʻoihana koʻikoʻi i kona wā;Ua wehewehe ʻia ka manaʻo kulekele o ka "hoʻonui i ka ʻelemakule a me ka hoʻoponopono hou ʻana o nā pipeline kūlanakauhale" i loko o ka palapala o ka hālāwai, ʻo ia hoʻi ka "moderately advanced infrastructure investment".Hiki ke ʻike ʻia ua piʻi ka wikiwiki o ka hoʻonui ʻana i ka pipeline gas ma Kina, e lawe mai ana i kahi koi nui no ka ʻoihana huahana paipu kila.
2. Kaʻoihana halihali paipuloaʻa i ka nui o ka hoʻohana ʻana i nā huahana paipu kila
Wahi a ka "Research on the Development Trend of China's Steel Pipe Products Industry and the Future Investment Forecast Report (2022-2029)" i hoʻokuʻu ʻia e Guanyan Report, i kēia manawa, ʻo ka hikina a me ke komohana o ka ikehu o Kina ka puʻunaue like ʻole, a me ka lawe ʻana i ka pipeline. loaʻa ka pōmaikaʻi nui i ka lawe ʻana i ka ikehu lōʻihi.Wahi a ka ʻikepili, i ka makahiki 2020, ʻo ka huina mile o ka ʻaila a me nā paipu kinoea hou i kūkulu ʻia ma Kina ma kahi o 5081 mau kilomita, me kahi o 4984 mau kilomita o nā pipeline kinoea kūlohelohe hou i kūkulu ʻia, 97 mau kilomita o nā paipu aila ʻaila hou i kūkulu ʻia, a ʻaʻohe. hou huahana aila paipu.Eia kekahi, e hoʻomau ʻia a hoʻomaka ʻia ka nui o ka mileage o ka aila nui a me ka pipeline ma 2020 a hoʻopau ʻia i 2021 a ma hope e manaʻo ʻia he 4278 mau kilomita, me 3050 mau kilomita o ke kinoea maoli, 501 mau kilomita o ka aila ʻaila a me 727 mau kilomita o ka aila hoʻomaʻemaʻe. paipu.Hiki ke ʻike ʻia he ʻoi aku ka nui o ka hoʻohana ʻana i nā huahana paipu kila ma Kina.
