Wahi a ka welded pipe production ikepili i paʻi ʻia e ka National Bureau of Statistics a me ka lālā paipu kila ma muli o ka ʻikepili hana o nā hui lālā e manaʻo ai i ka seamless steel pipe production ikepili, mai Ianuali a Dekemaba 2021, ʻo ka hana ʻana o ka paipu kila o 853.62 miliona. nā tona, i lalo he 3.66%;ʻO ka hoʻohana ʻana he 78,811,600 tons, ma lalo o 4.33% makahiki ma ka makahiki.Iwaena o lakou, welded paipu hana o 58.832 miliona tona, iho 3.57% makahiki ma ka makahiki;ʻO ka hoʻohana ʻana he 55.2763 miliona tons, ma lalo o 4.07% makahiki ma ka makahiki.ʻO ka hana i manaʻo ʻia o ka paipu kila seamless he 26.80.00 miliona tons, ma lalo o 3.86% makahiki ma ka makahiki;ʻO ka hoʻohana ʻana he 23.5353 miliona tons, me ka emi ʻana o ka makahiki he 4.93%.Hiki ke ʻike ʻia i ka makahiki 2021, ʻo ka paipu kila o Kina, ka paipu kila ʻole, ka hana paipu welded a me ka ʻai ʻana i hoʻemi ʻia i kēlā me kēia makahiki.Hōʻike ʻia ka hopena a me ka hoʻohana ʻana i nā paipu kila ma Kina i 2020-2021 ma ka Papa 1 a me ke Kiʻi 1.

Mai ka ʻikepili helu helu, ʻo ka holo holoʻokoʻa holoʻokoʻa o ka ʻoihana paipu kila o Kina i ka hapa mua o 2021, akā ʻike ʻia ka ulu ʻana o ka ulu ʻana, i hoʻohālikelike ʻia i ka hopena o nā kumukūʻai hao hao honua i piʻi nui i Mei, paipu, piʻi nui nā kumukūʻai pā. ʻO ka mea i koi aku i nā kumukūʻai kila i piʻi nui, akā ʻo kēia kūʻai ʻana i ka hopena nui i ka ʻoihana o lalo, e hoʻonāwaliwali ai ka noi.Eia kekahi, ʻo ka mokuʻāina o ka ʻoihana kila e hōʻemi i nā koi hana kila kila, ua hoʻopilikia pū kekahi i kekahi mau ʻoihana, no laila i ka makahiki 2021, ʻo ka hana ʻana o ka paipu kila o Kina kahi ʻano o ka emi ʻana.

2. Na kumukuai paipu kila ma Kina

Mai Nowemapa 2020, ma muli o ka piʻi nui ʻana o nā kumukūʻai o nā kumu waiwai nui e like me ka hao hao, ua hoʻonui nui ʻia nā kumukūʻai o ka billet a me ke kila kila ma Kina, e like me ka hōʻike ʻana ma ka Figure 2-3, a me nā kumukūʻai o ke kila. paipu.

Hōʻike ʻia ke kumu kūʻai o ka paipu kila seamless, paipu welded a me ka paipu galvanized ma Kina mai 2020 a 2021 i ka Figure 4. I waena o lākou, ke kumu kūʻai o φ 219 mm × 10 mm kikoʻī o ka paipu kila seamless piʻi wikiwiki mai Nowemapa 2020, ke kumu kūʻai. ua piʻi mai ka 4645 yuan a i ka 6638 yuan i Mei 2021 (ʻo ia ke kiʻekiʻe o ke kumukūʻai mai 2008), ma kahi o 2000 yuan, piʻi 42.9%;Ma hope o Mei 2021, ua hāʻule ke kumu kūʻai i 6,160 yuan i Iulai, i lalo kokoke i 500 yuan, a laila piʻi aʻe i 6,636 yuan i ʻOkakopa (ka lua kiʻekiʻe), a laila hāʻule i 5,931 yuan i Dekemaba.Ua oscillating ke kumu kūʻai ma kahi kiʻekiʻe mai ka hoʻomaka ʻana o ka makahiki.

ʻO ka makahiki 2021 ka makahiki maikaʻi loa no ka ʻoihana kila o Kina mai 2008, me ka hoʻomaikaʻi maikaʻi ʻana o ka ʻoihana.Eia nō naʻe, ʻo ia kekahi o nā huahana o ka ʻoihana hao a me ke kila, ʻaʻole i hoʻomaikaʻi ʻia ka paipu kila e like me ka pā, bar, wire a me ka profile.ʻO nā kumu penei: ʻo ka mea mua, ʻoiai ua piʻi nui ke kumukūʻai o ka paipu kila, ʻaʻole i piʻi ke kumukūʻai o ka paipu kila i ke kiʻekiʻe ma muli o ka mana o ke kumukūʻai aila haʻahaʻa a me ke kumu kūʻai haʻahaʻa o ka paipu ʻaila.Hōʻike ʻia ke kumukūʻai o ka paipu kila maʻemaʻe, ka pepa galvanized, ka pepa wela a me ka rebar ma Kina mai ʻApelila 2020 a Ianuali 2022 i hōʻike ʻia ma ke Kiʻi 5. Hiki ke ʻike ʻia ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ka galvanized sheet ma 2021 ma mua o ke kila seamless. paipu 300 ~ 750 yuan, a ʻo ke kumukūʻai o nā ʻano ʻelua i nā makahiki ʻē aʻe he kiʻekiʻe a haʻahaʻa, maʻamau ka fluctuating ma kahi o 200 yuan.ʻO ka lua, ma muli o ka piʻi nui ʻana o nā kumukūʻai maka a me nā mea kōkua, ke kū nei ka ʻokoʻa o ke kumukūʻai ma waena o ka paipu kila a me ka billet ma ke kiʻekiʻe o 2020, a ʻaʻole i hoʻomaikaʻi maikaʻi ʻia ka palena o nā huahana.ʻO ka mea nui, ʻo nā ʻoihana hana ʻaila puna wai, i hoʻopilikia ʻia e ke kumu kūʻai aila haʻahaʻa a me ke kumu kūʻai haʻahaʻa o ka paipu aila, paʻakikī ka hoʻokele ʻana o ka ʻoihana, ʻo ka hapa nui o nā ʻoihana ma ka ʻaoʻao o ka loaʻa kālā liʻiliʻi a i ʻole ka pohō, ke poho mau nei nā ʻoihana pākahi.

I ka makahiki 2021, ʻoiai ua hoʻoponopono ʻelua ka mokuʻāina i ka hoʻihoʻi ʻauhau ʻauhau o nā huahana kila, i hoʻihoʻi ʻia ka uku ʻauhau i 0, akā ʻaʻole i hoʻemi ʻia ka nui o ka paipu kila akā ua hoʻonui ʻia.ʻO nā kumu nui penei: ʻo ka mua, ma muli o ka hopena o COVID-19, ʻaʻole i hoʻomaka hou kekahi mau ʻoihana paipu kila haole i ka hana ʻana, a ua pōkole ka mākeke no kekahi manawa, a ua loaʻa nā kumukūʻai paipu kila honua. piʻi nui (ʻoi aku ka kiʻekiʻe o nā kumukūʻai o kekahi mau huahana i lawe ʻia aku ma mua o nā huahana kūloko);ʻO ka lua, hopohopo nā ʻoihana hoʻokuʻu aku e pili ana i nā ʻāina hahai e hoʻonui i nā kumukūʻai ma nā huahana kūʻai aku, no laila e hoʻonui, e wikiwiki i ka ikaika o ka lawe ʻana aku, ua hoʻonui nui ʻia ka nui o nā mea kūʻai aku i ka hapahā ʻehā.I Kekemapa 2021, ʻo 160.44% o ka awelika o nā mahina he 11 i hala.ʻO ka mea nui, ʻo ka lawe ʻana aku i nā paipu kila ʻole i ka mahina ʻo Dekemaba he 531,000 tons, 203.92 pākēneka o ka awelika o ka lawe ʻana aku o 260,400 tons i nā mahina 11 mua.Ua hoʻomau kēia ʻano i ka hapaha mua o 2022.

3.2 Nā mea nui e lawe aku i waho

Wahi a ka ʻikepili i hoʻokuʻu ʻia e ka China General Administration of Customs, China ka seamless steel pipe exports in 2021 3.3952 miliona tons, he makahiki-ma-makahiki ulu o 3.79%.Ma waena o lākou, he 1.2743 miliona tons ka hoʻokuʻu ʻia ʻana o ka pipeline, i lalo o 9.60% makahiki ma ka makahiki;He 906,200 tons ka nui o ka punawai aila i lawe aku i waho, he 2.81% o ka makahiki;He 151,800 tons ka ho'oku'u 'ia mai o ka paipu boiler seamless, he 15.22% ka emi o ka makahiki ma ka makahiki;ʻO ka hoʻokuʻu ʻia ʻana o ka paipu paipu welded he 757,700 tons, ma lalo o 9.16% makahiki ma ka makahiki;He 1,325,400 tons ka lawe ʻia ʻana o nā paipu hoʻoheheʻe kūikawā kūikawā a me ka huinahā like, a ʻoi aku ka 4.41% i kēlā me kēia makahiki.I ka makahiki 2021, ma muli o ka hopena o ka maʻi maʻi maʻi COVID-19 a me nā ʻauhau ʻauhau kūwaho kūloko, ua emi nui ka nui o ka hoʻopuka ʻana o nā ʻano nui ʻekolu o Kina o ka paipu seamless, seamless boiler pipe a me welded pipe.E ʻike i ka Papa 3 a me ke Kiʻi 7 no ka lawe ʻana aku i nā ʻano paipu kila nui ma Kina i 2020-2021.
