Amapayipi ensimbi okuvunguza asetshenziswa kakhulu ezinhlelweni zokuhlinzeka ngamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo, kanye nokwakhiwa kwamadolobha. Amapayipi ensimbi okuvunguza aphakathi kwemikhiqizo engu-20 ebalulekile eyenziwe ezweni lami. Okokuthutha okuwuketshezi: ukuhlinzekwa kwamanzi kanye nokukhipha amanzi. Ezokuthutha igesi: igesi yamalahle, isitimu, igesi ye-petroleum ewuketshezi. Ngezinhloso zesakhiwo: ukunqwabelanisa amapayipi, amabhuloho; amapayipi amadokhi, imigwaqo, izakhiwo zokwakha, njll. Ipayipi lensimbi elivunguzayo ipayipi lensimbi elivunguzayo elishiselwe inqubo yokushisela engaphansi kwe-arc enezintambo ezimbili emaceleni ekabili kusetshenziswa ipuleti lekhoyili yensimbi eyi-strip njengempahla eluhlaza, ukubumba okungaguquki kwe-extrusion lokushisa. Ipayipi lensimbi elivunguzayo liphakela umucu eyunithi yepayipi elishiselwe. Ngemva kokugoqwa ngama-roller amaningi, umucu uyagoqwa kancane kancane ukuze wenze ithubhu eliyindilinga elingenalutho elinegebe lokuvula. Lungisa inani elincishisiwe lerola ye-extrusion ukuze ulawule igebe lokushisela phakathi kuka-1-3mm, futhi wenze zombili iziphetho zejoyinti lokushisela ziguqe.

Umehluko phakathi kwepayipi lensimbi elivunguzayo kanye nepayipi elinembile lensimbi
Amapayipi ensimbi okuvunguza angahlukaniswa abe izigaba ezimbili ngokwezindlela zokukhiqiza: Kuvunguza futhi kuthungwe. Amapayipi ensimbi athungelwe abizwa ngokuthi amapayipi ensimbi aqondile. Amapayipi ensimbi okugobile angahlukaniswa abe amapayipi angenamthungo ashisayo aginqike, adonswe ngokubanda, amapayipi ensimbi anembayo, amapayipi anwetshwe ngokufudumeza, amapayipi aphenduka abandayo, namapayipi akhishwe ngokwezindlela zokukhiqiza. Amapayipi ensimbi okuvunguza enziwe ngensimbi yensimbi ye-carbon ephezulu noma i-alloy steel futhi angahlukaniswa abe yi-hot-rolled and cold-rolled (drawn). Isici esiyinhloko se-spiral steel pipe ukuthi ayinayo i-welding seams futhi ingakwazi ukumelana nokucindezela okukhulu.

Imikhiqizo ingaba nzima kakhulu njengezingxenye ezikhandiwe noma ezibandayo. Amapayipi ensimbi ashiselwe ahlukaniswe abe amapayipi ashiselwe esithandweni, amapayipi ashiselwe (resistance welded) ngogesi, namapayipi ashiselwe nge-arc azenzakalelayo ngenxa yezinqubo zawo zokushisela ezihlukene. Ngenxa yezindlela zabo zokushisela ezihlukene, bahlukaniswe ngamapayipi ashiselwe ngomthungo oqondile kanye namapayipi ashiselwe athandelene. Aphinde ahlukaniswe amapayipi ayindilinga ashiselwe ngenxa yokwakheka kwawo ekugcineni namapayipi ashiselwe amise okwesipesheli (isikwele, isicaba, njll.) ashiselwe.

Amapayipi ensimbi ashiselwe enziwe ngamapuleti ensimbi agingqelwe abe yizimo ze-tubular futhi ashiselwe ngemithungo yezinqe noma ama-spiral seams. Ngokwezindlela zokukhiqiza, ahlukaniswe ngamapayipi ensimbi ashiselwe okuthutha uketshezi olunengcindezi ephansi, amapayipi ensimbi ashiselwe uthungo oluvunguzayo, amapayipi ensimbi ashiselwe ikhoyili, amapayipi kagesi ashiselwe, njll. Amapayipi ensimbi okuvunguza angasetshenziswa kumapayipi omoya owuketshezi futhi amapayipi egesi ezimbonini ezahlukene. I-Welding ingasetshenziselwa amapayipi amanzi, amapayipi egesi, amapayipi okushisa, amapayipi kagesi, njll.

Amapayipi ensimbi anembile yimikhiqizo evele eminyakeni yamuva. Ikakhulukazi banokubekezelelana okuqinile kanye nobulukhuni embobeni yangaphakathi kanye nobukhulu bodonga lwangaphandle. Ipayipi lensimbi eliqondile liyimpahla yepayipi yensimbi enembe kakhulu ecutshungulwe ngomdwebo obandayo noma ngokuginqika okushisayo. Ngenxa yokuthi abukho ungqimba lwe-oxide ezindongeni zangaphakathi nangaphandle zamapayipi ensimbi amahle, akukho ukuvuza ngaphansi kwengcindezi ephezulu, ukunemba okuphezulu, ukukhanya okuphezulu, akukho ukuguquguquka ekugobeni okubandayo, akukho mifantu ekuqhumeni nasekufakeni isicaba, njll., isetshenziswa kakhulu khiqiza imikhiqizo enezingxenye zomoya noma ezisebenza ngogesi, njengamasilinda noma isilinda samafutha.
