Spiral Welded Steel Pipes Manufacturing Process
Ukukhetha Okubalulekile:
Amakhoyili Ensimbi: Amakhoyili ensimbi asezingeni eliphezulu akhethiwe, ngokuvamile enziwe ngensimbi enekhabhoni ephansi noma ephakathi nendawo, ukuze ahlangabezane nemishini edingekayo kanye nokwakheka kwamakhemikhali.
Ukuqaqa nokusika:
Ukuqaqa: Amakhoyili ensimbi ayaqaqa futhi acabangwe abe yifomu leshidi.
Ukusika: Insimbi eyisicaba iyasikwa ibe imicu yobubanzi obudingekayo. Ububanzi be-strip bunquma ububanzi bepayipi lokugcina.
Ukwakha:
I-Spiral Formation: Ucu lwensimbi luphakelwa ngochungechunge lwamarola alwakha kancane kancane abe umumo ozungezayo. Imiphetho ye-strip ihlanganiswa ndawonye ngephethini ye-helical ukwenza ipayipi.
Ukushisela:
I-Summerged Arc Welding (SAW): I-spiral seam yepayipi ihlanganiswe kusetshenziswa inqubo ye-arc welding engaphansi kwamanzi. Lokhu kuhilela ukusetshenziswa kwe-arc kagesi kanye ne-granular flux, ehlinzeka nge-weld eqinile, yekhwalithi ephezulu ene-spatter encane.
Ukuhlola I-Weld Seam: Umthungo we-weld uhlolelwa ikhwalithi kusetshenziswa izindlela zokuhlola ezingabhubhi njengokuhlola kwe-ultrasonic noma nge-radiographic.
Ukulinganisa nokubunjwa:
Izigayo zokulinganisa: Ipayipi elishiselwe lidlula ezigayweni zokulinganisa ukuze lifinyelele ububanzi obunembile kanye nobundingilizi obudingekayo.
Ukwandiswa: Ukunwetshwa kwamanzi noma okomshini kungasetshenziswa ukuze kuqinisekiswe ubukhulu bamapayipi afanayo kanye nokuthuthukisa izakhiwo zezinto ezibonakalayo.
Ukuhlola Okungonakali:
Ukuhlolwa kwe-Ultrasonic (UT): Kusetshenziselwa ukuthola amaphutha angaphakathi ku-weld seam.
Ukuhlolwa kwe-Hydrostatic: Ipayipi ngalinye lingaphansi kokuhlolwa kwengcindezi ye-hydrostatic ukuze kuqinisekiswe ukuthi liyakwazi ukubhekana nezingcindezi zokusebenza ngaphandle kokuvuza.
Ukuqeda:
I-Beveling: Iziphetho zamapayipi ziboshwe ukuze zilungiselele ukushiselwa endaweni yokufaka.
Ukwelapha Okungaphezulu: Amapayipi angathola ukwelashwa okungaphezulu okufana nokuhlanza, ukunamathiswa, noma ukugqumisa ukuze kuthuthukiswe ukumelana nokugqwala.
Ukuhlola Nokulawula Ikhwalithi:
Ukuhlola I-Dimensional: Amapayipi ahlolwe ukuthi ayahambisana yini nobubanzi, ukujiya kodonga, kanye nokucaciswa kobude.
Ukuhlolwa Komshini: Amapayipi ahlolelwa amandla aqinile, amandla esivuno, ubude, kanye nokuqina ukuze kuqinisekiswe ukuthi ahlangabezana nezindinganiso ezidingekayo.
Ukumaka nokupakisha:
Ukumaka: Amapayipi amakwe ngolwazi olubalulekile njengegama lomkhiqizi, imininingwane yepayipi, ibanga, usayizi, nenombolo yokushisa ukuze kulandeleke.
Ukupakisha: Amapayipi ayahlanganiswa futhi ahlanganiswe ngokwezidingo zamakhasimende, alungele ukuthuthwa nokufakwa.

Ukulawula Ikhwalithi Eqinile:
1) Ngesikhathi nangemva kokukhiqiza, izinduku ezi-4 ze-QC ezinesipiliyoni seminyaka engaphezu kwemi-5 zihlola imikhiqizo ngokungahleliwe.
2) Ilabhorethri kazwelonke egunyaziwe enezitifiketi ze-CNAS
3) Ukuhlolwa okwamukelekayo okuvela enkampanini yangaphandle eqokwe/ekhokhelwa umthengi, njenge-SGS, BV.
4) Igunyazwe yiMalaysia, Indonesia, Singapore, Philippines, Australia, Peru kanye ne-UK. Siphethe i-UL/FM, ISO9001/18001, izitifiketi ze-FPC
