Ububanzi obukhulu i-spiral welded pipe (saw)iwuhlobo lwepayipi olunezinhlobonhlobo zokusetshenziswa futhi lungasetshenziswa emikhakheni nasezimbonini ezahlukene. Okulandelayo, ake sihlolisise ukusetshenziswa kwamapayipi ensimbi anobubanzi obukhulu.

Okokuqala nje, amapayipi amakhulu ashiselwe okuvunguzayo angasetshenziswa njengamapayipi amanzi.

Amadolobha anezimboni nezindawo ezithuthukisiwe kwezolimo adinga amanzi amaningi ukuze ahlangabezane nezidingo zokukhiqiza kanye nezidingo zokuphila, kanti amapayipi ensimbi avunguzayo anezimpawu zokumelana nokucindezelwa, ukumelana nokugoba, ukumelana nokushisa okuphezulu, nokumelana nokugqwala, okungaqinisekisa ukuphepha nokuzinza kokulethwa kwamanzi. , ngakho-ke zisetshenziswa kakhulu kwezokuthutha Insimu yokukhiqiza amanzi namanzi asekhaya.

Okwesibili, amapayipi amakhulu ashiselwe okuvunguzayo angasetshenziswa njengamapayipi kawoyela.
Eminyakeni yamuva nje, ngokuthuthuka komnotho wembulunga yonke, isidingo nokukhishwa kwemithombo kawoyela negesi siyaqhubeka nokwanda, kanti amapayipi ensimbi avunguzayo adlala indima ebaluleke kakhulu ekuthuthweni kukawoyela negesi. Ukusetshenziswa kwamapayipi ensimbi anobubanzi obukhulu njengamapayipi kawoyela akukwazi nje kuphela ukuqinisekisa ikhwalithi nokuphepha kwamapayipi kawoyela, kodwa futhi kunciphisa izindleko zokunakekela kanye nobunzima.

Ngaphezu kwalokho, amapayipi amakhulu ashiselwe okuvunguzayo angasetshenziswa njengezinto zokwakha.
Emkhakheni wokwakha, isidingo semakethe siyakhula. Ngenxa yezici zamandla aphezulu, ukuphepha nokuthembeka, ukufakwa komsindo nokushisa ukushisa, amapayipi ensimbi okuvunguza asetshenziswa kabanzi ezakhiweni zesakhiwo sensimbi kanye nezakhiwo ezinde emkhakheni wokwakha.

Ipayipi elihlanganisiwe elivunguzayo elinobubanzi obukhulu lingasetshenziswa nakweminye imikhakha yokufaka isicelo. Isibonelo, imishini emikhulu ye-petrochemical, ifenisha yezindlu esezingeni eliphezulu, ukukhiqizwa kwezimoto, amakhemikhali esakhiwo sensimbi nezisekelo ezithwala umthwalo wobunjiniyela bakamasipala, njll.

Izinzuzo zamapayipi amakhulu ashiselwe okuvunguzayo:

Amandla aphezulu: Ipayipi elishiselwe okuvunguzayo elinobubanzi obukhulu linamandla aqinile aqinile, amandla acindezelayo kanye nokumelana nomthelela, futhi lifanele izindawo ezihlukahlukene ezinokhahlo.
Ukumelana nokugqwala okuhle: Ubuchwepheshe bokwelashwa kwamapayipi ensimbi (njengopende ovimbela ukugqwala, ukunamathela kwe-epoxy resin, njll.) kungathuthukisa ukumelana nokugqwala kwamapayipi ensimbi futhi andise impilo yawo yesevisi.
Ukonga izinto zokwakha kanye nezindleko zokunciphisa: Inqubo yokukhiqiza yamapayipi ensimbi enobubanzi obuvunguzayo inganciphisa ngempumelelo ukusetshenziswa kwezinto ezibonakalayo futhi inciphise izindleko zobunjiniyela.
Ukusebenza kokuvikela imvelo: Izinto zamapayipi ensimbi zingaphinda zisetshenziswe, okuhambisana nomqondo wokuvikelwa kwemvelo okuluhlaza.
Ukwakhiwa okulula: Ipayipi lensimbi elivunguzayo lixhunywe ngokushisela, futhi inqubo yokwakha ilula futhi iyashesha.

Izinyathelo zokuphepha zokuthenga amapayipi amakhulu ashiselwe okuvunguzayo:

Amandla omkhiqizi: Khetha umkhiqizi wamapayipi ensimbi asongelwe ngamandla aqinile nolwazi olucebile lokukhiqiza ukuze uqinisekise ikhwalithi yomkhiqizo ethembekile.
Ikhwalithi yomkhiqizo: Qonda okubalulekile, amandla, ukumelana nokugqwala nezinye izakhiwo zamapayipi ensimbi, bese ukhetha imikhiqizo yekhwalithi ephezulu ehlangabezana nezidingo zobunjiniyela.
Intengo enengqondo: Qhathanisa izingcaphuno zabakhiqizi abaningi bese ukhetha imikhiqizo enezindleko eziphezulu zokusebenza.
Ikhwalithi yesevisi: Qonda izinsizakalo zomkhiqizi zokuthengisa kwangaphambili, ukuthengisa kanye nangemuva kokuthengisa, bese ukhetha umkhiqizi onokwaneliswa kwesevisi ephezulu.
