Carbon Steel Seamless Pipe
Seamless Steel Pipe amapangidwa kuchokera kuchitsulo chozungulira cholimba'billet'chomwe chimatenthedwa ndi kukankhira kapena kukoka pamtundu wina mpaka chitsulocho chipangidwe kukhala chubu lopanda kanthu.Chitoliro chopanda msoko chimatsirizidwa kuti chikhale chofanana ndi makulidwe a khoma kuchokera pa 1/8 inchi mpaka 32 inchi OD.Carbon Steel Seamless Pipes / Tubes Carbon steel ndi aloyi wopangidwa ndi chitsulo ndi kaboni.Gawo la mpweya muzitsulo limakhudza kuuma, mphamvu ya elasticity ndi ductility ya carbon steel.Chitoliro chachitsulo chosasunthika cha carbon steel kapena ingot yolimba yachitsulo imapangidwa ndi chubu cha capillary kudzera mu dzenje, kenako kudzera pa kuyimba kotentha, kozizira kapena kozizira kumapangidwa.Msokonezo mpweya zitsulo chitoliro mu makampani zitsulo China ali ndi udindo wofunika.Seamless carbon steel chitoliro ndi chubu chozungulira, mapaipi odulira makina opangira ma dzira kuti adutse pafupifupi 1 m kutalika opanda kanthu, ndikutumizidwa ndi kutentha kwa ng'anjo ya conveyor lamba.Billet amadyetsedwa mu ng'anjo yotentha, kutentha kumakhala pafupifupi madigiri 1200 Celsius.Mafuta ndi hydrogen kapena acetylene.Kuwongolera kutentha kwa ng'anjo ndiyo nkhani yaikulu.Chubu lozungulira linatuluka kuti liwombetse makinawo kudzera mumphamvu ya mpweya.Nthawi zambiri nkhonya wamba ndi tapered mpukutu perforation makina, nkhonya mkulu kupanga dzuwa, mankhwala khalidwe, lalikulu m'mimba mwake kukula dzenje, akhoza kuvala zosiyanasiyana zitsulo.Perforation, chubu chozungulira chakhala chikugubuduza mtanda wa mipukutu itatu, kugudubuza kapena kutulutsa.Chofinyidwa pa chubu pambuyo kukula.Kukula pobowola mothamanga kwambiri ma rotary cone mu billet kupanga chubu.Chitoliro cha m'mimba mwa mphero kuti mudziwe kutalika kwa kubowola awiri.Pambuyo chitoliro mwa sizing mu kuzirala nsanja, kuzirala ndi kutsitsi madzi, zitsulo pambuyo kuzirala, ayenera kuwongola.Pambuyo pa lamba wachitsulo wotumizidwa ndi kuwongola makina oyesera zitsulo (kapena kuyesa kukakamiza) kuyesa mkati.Ngati chitoliro mkati ming'alu, thovu ndi mavuto ena adzakhala wapezeka.Pambuyo chitoliro komanso kudzera okhwima khalidwe ulamuliro Buku kusankha.Ubwino wachitsulo, kugwiritsa ntchito manambala a utoto wopopera, mawonekedwe, nambala yopangira zambiri.Ndi crane kulowa m'nkhokwe.
