Njengoba izinhlelo zokusebenza zezimboni zivele zavela futhi zikhule ziyinkimbinkimbi, imikhiqizo nezinhlelo ezibakhonzayo kuye kwadingeka ukuthi zigcine ijubane.
Yize izindlela eziningi zokukhiqiza amapayipi zikhona, izingxoxo ezivelele kakhulu embonini ukuqhathanisa ukumelana nokuphikiswa kwe-Welded Welded (ERW) kanye namapayipi ensimbi angenamthungo (SML). Manje iyiphi engcono?
Umehluko phakathi kwepayipi lensimbi engenasici angenasici kanye nepayipi elidume kakhulu ngamagama athandwa kakhulu ngumehluko ngaphandle kwe-weld, noma kunjalo, empeleni empeleni umehluko enqubweni yokukhiqiza. NguMuhluko wenqubo yokukhiqiza ebanikeza bobabili ukusebenza nenhloso.
Ekhiqiza ipayipi elingenamthungo
Ipayipi lensimbi engenamthungo lenziwa ngensimbi eyodwa eshidi, ingaphezulu lepayipi lensimbi ngaphandle komkhondo wokuxhuma, elibizwa nge-seamless yensimbi. Ngokwendlela yokukhiqiza, ipayipi elivuthayo elivuthayo, ipayipi elibandayo elibandayo, ipayipi elibandayo lokudonsa, ipayipi le-extrusion nepayipi lepayipi lihlukaniswe ngomthungo.
Amapayipi angenamthungo aqala njenge-hunk eqinile ye-cylindrical yensimbi ebizwa ngokuthi yi-billet. Ngenkathi kusashisa, imali ekhokhiswayo isebenzisa i-mandrel igwazwe isikhungo. Isinyathelo esilandelayo ukugoqa futhi welule imali ekhokhwayo. Amabhili asongelwa ngokunembile futhi anwetshwa kuze kube ubude, ububanzi kanye nobubanzi obudongeni obuchazwe ku-oda lamakhasimende.
Ukukhiqiza ipayipi le-welded
Isimo sokuqala sepayipi eline-welded yimicu yensimbi ende, ehlanganisiwe. Sika ubude obufunayo nobubanzi bokwakha ishidi lensimbi elixakile. Ububanzi beshidi buzoba umjikelezo wangaphandle wepayipi, futhi leli nani lingasetshenziswa ukubala ububanzi bayo bokugcina abangaphandle. Ishidi elingunxande lidlula kwiyunithi yokugoqa ukuze izinhlangothi ezinde zigobele komunye nomunye ukwakha isilinda. Ngesikhathi se-ERW, imisinga efinyelela imvamisa ephezulu idluliswa phakathi kwemiphetho, ibangele ukuba incibilike futhi ihlanganise ndawonye.
Umehluko jikelele ukuthi:
Ipayipi elinenkani libhekwa njengelibuthakathaka ngokwemvelo ngoba lifaka i-Weld eyodwa. Amashubhu angenamthungo aswele lesi sici esibonakalayo sesakhiwo futhi ngenxa yalokho abhekwa ephephile. Yize ipayipi elinezinwele lifaka phakathi okuhlanganisiwe, le ndlela yokukhiqiza yenza ukubekezelela ipayipi kwe-welded kungadluli izidingo zekhasimende futhi ubukhulu buyafana. Yize ipayipi elingenamthungo linezinzuzo ezisobala, ukugxekwa kwepayipi elingenamthungo ukuthi izinqubo zokugoqa nezinolulekile zikhiqiza ubukhulu obungahambelani.
E-oyili, igesi, isizukulwane samandla kanye nezimboni zemithi, ingcindezi eningi ephezulu kanye nezicelo zokushisa eziphakeme zidinga amapayipi angenamthungo. Amapayipi we-welding ngokuvamile ashibhile ukukhiqiza futhi asetshenziswe kabanzi inqobo nje uma nje izinga lokushisa, ingcindezi kanye nezinye izinto eziguquguqukayo awedluli amapharamitha achazwe kumazinga afanele.
Ngokufanayo, akukho mehluko ekusebenzeni phakathi kwamapayipi ensimbi angenamthungo kuzinhlelo zokusebenza zesakhiwo. Ngenkathi bobabili beshintshana, akunangqondo ukucacisa ipayipi elingenamthungo lapho ipayipi elishibhile le-welded lisebenza ngokulinganayo.
