27SiMN Yozimitsidwa Ndi Chitsulo Chotentha API Series Pipeline Steel Pipe Carbon Steel Round Pipe

Mafotokozedwe Akatundu

Chitoliro chachitsulo cha kaboni kapena chitoliro cha chitsulo cha kaboni chimapangidwa ndi ingot yachitsulo kapena chitoliro cholimba chopanda kanthu pobowoleza, kenako chimapangidwa ndi kugudubuza kotentha, kugudubuza kozizira kapena kujambula kozizira. Mpweya zitsulo chitoliro amatenga mbali yofunika kwambiri mu makampani China zitsulo chitoliro. The zopangira mpweya zitsulo chitoliro ndi kuzungulira chubu akusowekapo. Chozungulira chubu chopanda kanthu chimadulidwa ndikukonzedwa ndi makina odulira, ndipo chopanda kanthu chokhala ndi kukula pafupifupi 1m chimatumizidwa ku ng'anjo kuti chiwotche kudzera pa lamba wotumizira. Billet imatumizidwa ku ng'anjo kuti itenthedwe kutentha pafupifupi madigiri 1200 Celsius. Mafutawa ndi hydrogen kapena acetylene. Kuwongolera kutentha mu ng'anjo ndilo vuto lalikulu. Pambuyo pozungulira chubu billet kutulutsidwa mu ng'anjo, iyenera kupyozedwa kupyolera mu kubowola kokakamiza. Nthawi zambiri, woboola wodziwika kwambiri ndi woboola mpukutu. Woboola uyu ali ndi kuthekera kwakukulu kopanga, mtundu wabwino wazinthu, kukula kwakukulu kwa perforation ndipo amatha kuvala magiredi osiyanasiyana achitsulo. Pambuyo perforation, wozungulira chubu akusowekamo ndi motsatizana adagulung'undisa atatu mpukutu mtanda kugubuduza, mosalekeza kugudubuza kapena extrusion. Pambuyo extrusion, chotsani chitoliro kwa kukula. Makina ojambulira amazungulira mumluza wachitsulo mwachangu kwambiri kudzera pakubowola kowoneka bwino kuti apange chitoliro chachitsulo. The awiri m'mimba mwake wa zitsulo chitoliro anatsimikiza ndi akunja awiri kutalika kwa sizing makina pang'ono. Pambuyo poyesa, chitoliro chachitsulo chimalowa munsanja yozizirira ndipo chimakhazikika ndi kupopera madzi. Pambuyo pozizira, chitoliro chachitsulo chidzawongoledwa. Pambuyo kuwongola, chitoliro chachitsulo chimatumizidwa ku chowunikira chachitsulo (kapena kuyesa kwa hydrostatic) ndi lamba wotumizira kuti azindikire zolakwika zamkati. Ngati pali ming'alu, thovu ndi mavuto ena mkati mwa chitoliro chachitsulo, adzadziwika. Mipope yachitsulo iyenera kusankhidwa mosamala ndi dzanja pambuyo poyang'anitsitsa khalidwe. Pambuyo poyang'aniridwa ndi chitoliro chachitsulo, chiwerengero, ndondomeko, chiwerengero cha batchi yopangira, ndi zina zotero ziyenera kupakidwa utoto. Ndipo adakwezedwa m'nyumba yosungiramo katundu ndi crane.

27SiMn Chitoliro chachitsulo = 27 silicon manganese chitsulo chitoliro, chomwe ndi chimodzi mwa zida za chitoliro chachitsulo chosasunthika, ndipo mpweya wa carbon uli pakati pa 0.24-0.32%. SIMN imatchulidwa padera chifukwa zomwe zili mu silicon manganese muzinthu zisanu (carbon C, silicon Si, manganese Mn, phosphorous P, sulfure s) ndi za 1.10-1.40%.

Zomwe zili: zakhala zikugwira ntchito m'munda wa chitoliro chopanda chitsulo ku China kwazaka zopitilira 20. Gululi lili ndi mizere yopangira zitsulo zopitilira 10, zomwe zimapanga 27SiMn zozimitsidwa komanso kupsya chitsulo chitoliro, chitoliro chachitsulo cha API, chitoliro cha kaboni chitsulo chozungulira ndi chitoliro chachitsulo chaku America. Iwo ali osiyanasiyana ntchito. Tsopano makasitomala ake akuluakulu ali ku South Africa, Central Asia, Europe ndi mayiko ena, ndi matani masauzande ambiri kuti apereke zofuna za makasitomala.
