Zopangira zitoliro zachitsulo zimatanthawuza zinthu zokhudzana ndi mapaipi achitsulo, omwe amagwiritsidwa ntchito kwambiri pamakina omanga, malo ogulitsa nyumba (scaffolding).chitoliro chachitsulo, madzi, chitoliro cha mpweya, chitoliro chotetezera moto), mafuta ndi gasi (chitoliro cha mafuta, chitoliro cha payipi), kapangidwe kachitsulo (mbale yachitsulo), mphamvu yamagetsi (structural carbon zitsulo chitoliro), galimoto ndi galimoto (mwatsatanetsatane chitoliro chachitsulo chosasunthika) ndi mafakitale ena, ndipo ndi mitundu yofunikira kwambiri yazitsulo.
1. Kumanga mapaipi amagetsi ndi mafakitale ogulitsa nyumba kumakhala mphamvu yayikulu yoyendetsera kugwiritsira ntchito zinthu zachitsulo
M'malingaliro otsogolera a pulani ya 13 yazaka zisanu yachitukuko chamakampani azitsulo zachitsulo chotulutsidwa ndi boma, makina omanga, malo, katundu, mafuta ndi gasi ndiye minda yayikulu yogwiritsira ntchito zida zachitsulo ku China, zomwe zimawerengera 15%, 12.22%, 11.11% ndi 10% motsatana.
Kukula kwa mizinda ndi "malasha ku gasi" kwathandizira kukula kwa msika wa gasi wokhalamo.Gasi amagawidwanso gasi, gasi wa liquefied ndi gasi wachilengedwe, pomwe mpweya wachilengedwe umayendetsedwa ndi mapaipi.Pakalipano, mizinda yaing'ono ndi yapakati ku China ndi matauni, omwe amagwiritsa ntchito malasha monga gwero lalikulu la mphamvu, ali ndi malo akuluakulu oti alowe m'malo.Ndi kukwezedwa ndi kuthandizidwa ndi mfundo ya "malasha ku gasi", kukula kwa msika wa gasi wachilengedwe ku China kwakula pang'onopang'ono, ndipo njira yopititsira patsogolo mizinda ikukulirakulira, ndipo kukula kwa msika wa gasi wokhala kunyumba ukupitilira kukwera.
Chifukwa chake, potengera kukula kwamatauni, kugwiritsa ntchito gasi ku China kudzakula pang'onopang'ono, ndikuyendetsa kukula kwapaipi yapaipi ya gasi, ndikuwonjezera kufunikira kwamakampani opanga zitoliro zachitsulo.Malinga ndi deta, mtunda wa mapaipi a gasi ku China udzafika makilomita 83400 mu 2020, kukwera 3% chaka ndi chaka, ndipo akuyembekezeka kufika makilomita 85500 mu 2021.
Kuonjezera apo, malinga ndi Ndondomeko ya Zaka khumi ndi zinayi, kukonzanso mapaipi ndi kumanga kuyenera kutengedwa ngati ntchito yofunika kwambiri ya zomangamanga panthawi yake;Malingaliro a ndondomeko ya "kufulumizitsa ukalamba ndi kukonzanso mapaipi a m'tawuni" adatanthauzidwa mu chikalata cha msonkhano, chomwe chinaphatikizapo "ndalama zapamwamba za zomangamanga".Zitha kuwoneka kuti kufulumira kwa kukweza mapaipi a gasi ku China kwawonjezeka, kubweretsa malo ofunikira kwambiri pamakampani opanga zitsulo.
2. Themakampani oyendetsa mapaipilili ndi kuthekera kokulirapo kwa zinthu zapaipi zachitsulo
Malinga ndi "Research on the Development Trend of China's Steel Pipe Products Industry and the Future Investment Forecast Report (2022-2029)" yotulutsidwa ndi Lipoti la Guanyan, pakadali pano, mbali zakum'mawa ndi kumadzulo kwa mphamvu zaku China zimagawidwa mosagwirizana, komanso mayendedwe amapaipi. ali ndi mwayi waukulu pamayendedwe amphamvu akutali.Malinga ndi kafukufukuyu, mu 2020, mtunda wonse wa mapaipi amafuta ndi gasi omwe angomangidwa kumene ku China ndi pafupifupi makilomita 5081, kuphatikiza pafupifupi makilomita 4984 a mapaipi a gasi omwe angomangidwa kumene, ma kilomita 97 a mapaipi amafuta omwe angomangidwa kumene, ndipo palibe. mapaipi atsopano amafuta.Kuphatikiza apo, kuchuluka kwa mapaipi akulu amafuta ndi gasi omwe apitirire kapena kuyambika mu 2020 ndikumalizidwa mu 2021 ndipo pambuyo pake akuyembekezeka kukhala makilomita 4278, kuphatikiza ma kilomita 3050 amafuta achilengedwe, ma kilomita 501 amafuta opanda mafuta ndi ma kilomita 727 amafuta oyeretsedwa. mapaipi.Zitha kuwoneka kuti mayendedwe a mapaipi aku China ali ndi mphamvu zambiri zamapaipi azitsulo.
