I-Seamless Carbon Steel Pipe uhlobo lwepayipi elisetshenziswa kabanzi ensimini yezimboni. Inqubo yayo yokukhiqiza ayihileli noma yikuphi ukufudumala, yingakho igama elithi "seamless". Lolu hlobo lwepayipi luvame ukwenziwa ngensimbi esezingeni eliphakeme yekhabhoni noma ngensimbi ye-alloy ngokugoqa okushisayo noma okubandayo. I-Seamless Carbon Steel Pipe isetshenziswa kabanzi emikhakheni eminingi efana namafutha, igesi yemvelo, imboni yamakhemikhali, i-boological, ukuhlola okuhle kwemishini ngenxa yokumelana nokushisa okuhle. Isibonelo, amapayipi ensimbi angenamthungo ama-boilers wengcindezi aphansi naphakathi asetshenziselwa ukukhiqiza amapayipi aseSteate asezingeni eliphakeme, amapayipi abilayo wamanzi namapayipi anamanzi aphezulu ama-boilers we-locomotive ahlukahlukene wengcindezelo. Futhi amapayipi ensimbi angenamthungo wama-boilers aphezulu wengcindezelo asetshenziselwa ukwenza amapayipi okushisa kwamanzi okushisa ama-boilers amanzi anengcindezi ephezulu nangaphezulu. Ngaphezu kwalokho, amapayipi e-carbon engenamthungo nawo angasetshenziswa ukukhiqiza izingxenye ezihlelekile kanye nezingxenye zemishini, njengezimoto ezihamba ngezimoto, ozimele webhayisekili, kanye nokwakhiwa kwensimbi ekwakheni. Ngenxa yenqubo yayo yokukhiqiza, amapayipi e-carbon engenamthungo angamelana nezingcindezi eziphakeme ngesikhathi sokusebenzisa futhi azithambekele ekuvuzeni, ngakho-ke zibaluleke kakhulu ekudlulisela uketshezi.
Ukuhlukaniswa kwamapayipi e-carbon engenamthungo ikakhulukazi kususelwa ezintweni zokukhiqiza nokusetshenziswa. Ngokwendlela yokukhiqiza, amapayipi e-Carbon engenamthungo angahlukaniswa izigaba ezimbili: asongelwe ama-hot and obandayo (adonswe). Amapayipi ensimbi asongelwe avuselelayo afaka amapayipi ensimbi ajwayelekile, amapayipi ensimbi aphansi nangaphakathi nendawo, amapayipi ensimbi aphezulu, amapayipi ensimbi angenazinsimbi, amapayipi e-petroleum, lapho kugoqwa khona (kudonswa) Amapayipi ensimbi angenamthungo afaka amapayipi ensimbi amancanyana e-carbon, amapayipi ensimbi omncane, amapayipi ensimbi angenazinsimbi namapayipi ensimbi ahlukahlukene akhethekile. Ukucaciswa kwamapayipi ensimbi angenamthungo kuvame ukuvezwa kumamilimitha wobubanzi obungaphandle nobukhulu bodonga. Izinto ezisetshenziswayo zifaka insimbi eyejwayelekile nekhwalithi ephezulu yekhabhoni (efana ne-Q215-A kuya ku-Q275-a ne-50 insimbi), i-alloy yensimbi ephansi (enjenge-16mnv, i-16mn, i-steel engasho lutho . Ukukhethwa kwalezi zinto zokwenziwa kuhlobene namandla, ukumelana nokucindezela kanye nokuphikiswa kokugqwala kwepayipi, ngakho-ke kuzoba nezidingo ezahlukahlukene zezinto ezibonakalayo ezinhlelweni ezahlukahlukene zezimboni. Isibonelo, ama-steelbon aphansi anjenge-No. 10 no-20 Insimbi engu-20 asetshenziselwa amapayipi okulethwa koketshezi, ngenkathi ama-carbon ephakathi anjenge-45 no-40cr asetshenziselwa ukwenza izingxenye zemishini, ogandaganda . Ngaphezu kwalokho, amapayipi ensimbi angenamthungo kufanele alawule kahle ikhwalithi ngesikhathi sokukhiqiza, kufaka phakathi ukuhlolwa kokwakheka kwamakhemikhali, ukuhlolwa kwempahla yamakhemikhali, ukuhlolwa kwengcindezi yamanzi, ukuqinisekisa ukuthembeka kwabo nokuphepha ngaphansi kwezimo ezahlukahlukene zokusebenza. Inqubo yokukhiqiza yamapayipi e-carbon yensimbi engenamthungo nayo ibaluleke kakhulu. Kubandakanya izinyathelo eziningi ezifana nokuqothuka, ukugoqa okushisayo, ukugibela okubandayo noma umdwebo obandayo we-ingots noma amashubhu aqinile, futhi isinyathelo ngasinye sidinga ukuthi kulawulwe umkhiqizo wokugcina. Ukwenza isibonelo, ukukhiqizwa kwamapayipi ensimbi angena emthungo ashushulule adinga ukufudumeza i-tube mali acishe abe ngu-1200 degrees Celsius, bese embhoboza ngebhontshisi nge-roller obliqur, ukuqhuma okuqhubekayo noma ukukhishwa. Amapayipi ensimbi agoqwe abandayo adinga ukuthi i-tube malit izothathwa ithathwe ngaphambi kokuba kube khona ukubanda (ukudonswa) ukufeza usayizi owufunayo. Lezi zinqubo zokukhiqiza eziyinkimbinkimbi azigcini ngokuqinisekisa ikhwalithi yangaphakathi yepayipi lensimbi engenamthungo, kodwa futhi likunikeze ukunemba okungcono nokuqedwa komhlaba. Kuzinhlelo zokusebenza ezisebenzayo, amapayipi e-carbon engenamthungo asetshenziswa kabanzi kwizimboni eziningi ezinjenge-oyela, igesi, imboni yamakhemikhali, ukonsela amanzi, njll ngenxa yokusebenza kwawo okuhle nokwethembeka. Bayingxenye ebaluleke kakhulu embonini yanamuhla. Noma ngabe kusezingeni eliphakeme lokushisa kanye nezindawo eziphakeme zengcindezi noma emithonjeni yezindaba ezilonakalisayo, amapayipi e-carbon engenamthungo angakhombisa ukusebenza kwawo okuhle futhi anikeze iziqinisekiso eziqinile zokusebenza okuphephile kwezinhlelo eziphephile zezinhlelo eziphephile zezinhlelo zezimboni.
Ububanzi bamapayipi e-carbon engenamthungo angasuka ku-DN15 kuya ku-DN2000mm, ukushuba udonga kuyahlukahluka kusuka ku-2,5mm kuya ku-30mm, futhi ubude buvame phakathi kuka-3 no-12m. Lezi zinhlaka ezinobukhulu zivumela amapayipi e-carbon engenamthungo ukuze asebenze ngokuqine ngaphansi kwengcindezi ephezulu kanye nezindawo eziphakeme zokushisa, ngenkathi futhi eqinisekisa ukuthembeka kwabo ngesikhathi sokuhamba nokufakwa. Ngokusho kwe-GB / T 17395-2008 ejwayelekile, usayizi, ukwakheka, isisindo nokuphambuka okuvumelekile kwamapayipi ensimbi angenamthungo kulawulwa ngokuqinile ukuze kuqinisekiswe ikhwalithi yomkhiqizo nokuphepha. Lapho ukhetha amapayipi e-carbon engenamthungo, kubalulekile ukucubungula ububanzi bawo bangaphakathi, ububanzi obungaphandle, ubukhulu nobude, yizinto ezibalulekile ekunqumeni ukusebenza kwepayipi. Isibonelo, ububanzi obungaphakathi bunquma usayizi wesikhala soketshezi ukuze udlule, ngenkathi ububanzi obungaphandle nobubanzi obuhlobene kakhulu nomthamo wepayipi. Ubude buthinta indlela yokuxhumana yepayipi kanye nobunzima bokufakwa.
