Ipayipi lensimbi elishiselwe, elaziwa nangokuthi ipayipi elishiselwe, ipayipi lensimbi elenziwe ngepuleti lensimbi noma ngomugqa wensimbi ngemuva kokucwiliswa nokushiselwa.Amapayipi ensimbi ashiselwe anenqubo elula yokukhiqiza, ukusebenza kahle kokukhiqiza okuphezulu, izinhlobo eziningi kanye nokucaciswa, kanye nokutshalwa kwezimali okuncane kwemishini, kodwa amandla ajwayelekile aphansi kunalawo amapayipi ensimbi angenamthungo.Kusukela ngeminyaka yawo-1930s, ngokuthuthuka okusheshayo kokukhiqizwa okuqhubekayo kwensimbi ye-strip ephezulu kanye nokuthuthuka kobuchwepheshe bokushisela nokuhlola, ikhwalithi yama-welds ibilokhu ithuthukiswa ngokuqhubekayo, izinhlobo kanye nokucaciswa kwamapayipi ensimbi ashiselwe kuye kwanda, nokuningi. futhi amasimu amaningi athathe indawo yamapayipi ensimbi angajwayelekile.Ipayipi lensimbi yomthungo.Amapayipi ensimbi ashiselwe ahlukaniswe abe amapayipi ahlanganisiwe aqondile kanye namapayipi ashiselwe okuvunguza ngokwendlela yokushisela.Inqubo yokukhiqiza ipayipi ehlanganisiwe ye-seam ilula, ukusebenza kahle kokukhiqiza kuphezulu, izindleko ziphansi, futhi ukuthuthukiswa kuyashesha.Amandla epayipi elishiselwe elivunguzayo ngokuvamile aphakeme kunalawo omthungo oshiselwe ipayipi oqondile.Kodwa-ke, uma kuqhathaniswa nobude obufanayo bepayipi lomthungo oqondile, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.Ngakho-ke, amapayipi amaningi ashiselwe anama-diameter amancane asebenzisa i-seam welding eqondile, futhi iningi lamapayipi ahlanganisiwe anama-diameter amakhulu asebenzisa i-spiral welding.
Inqubo evamile yokwenza ipayipi lensimbi lomthungo oqondile yinqubo yokwenza i-UOE kanye nenqubo yokwenza ipayipi lensimbi ye-JCOE.Ngokwesicelo, ihlukaniswe ngamapayipi ashiselwe jikelele, ipayipi elishiselwe, ipayipi elishiselwe umoya-mpilo, ipayipi le-wire casing, ipayipi le-metric welded, ipayipi le-idler, ipayipi lepompo elijulile, ipayipi lemoto, ipayipi le-transformer, ipayipi kagesi elinezindonga ezincane, welding kagesi ipayipi emise okukhethekile kanye Kuvunguza ashiselwe pipe.
Ngokuvamile amapayipi ensimbi ashiselwe asetshenziselwa ukuthutha uketshezi olunomfutho ophansi.Yenziwe nge-Q195A.Q215A.Q235A insimbi.Futhi iyatholakala kwezinye izinsimbi ezithambile okulula ukuzishisela.Ipayipi lensimbi lidinga ukuhlolwa ukucindezelwa kwamanzi, ukugoba, ukwenza isicaba, njll. noma umenzi angenza ukuhlolwa okuthuthukisiwe ngokwemibandela yawo.Ipayipi lensimbi elishiselwe ngokuvamile linezidingo ezithile kwikhwalithi ephezulu, futhi ubude bokulethwa ngokuvamile buyi-4-10m, engacelwa ngokuvumelana nezidingo zangempela.Umkhiqizi uletha ngobude obungaguquki noma ubude obukabili.
Ukucaciswa kwepayipi elishiselwe kusebenzisa ububanzi obuningi ukuze kubonise ukuthi ububanzi obujwayelekile buhlukile kulowo wangempela.Ipayipi elishiselwe lingahlukaniswa libe izinhlobo ezimbili: ipayipi lensimbi elinezindonga ezincane kanye nepayipi lensimbi enodonga oluwugqinsi ngokuvumelana nobukhulu obucacisiwe bodonga.
Amapayipi ensimbi ashiselwe asetshenziswa kakhulu kumaphrojekthi wokudlulisa uketshezi olunomfutho ophansi, amaphrojekthi wesakhiwo sepayipi lensimbi, njll. ngoba amanani awo aphansi kunalawo acaciswe okufanayo.
