Ukuhlaziywa Okuqhathaniswayo Kwemibhobho Eshiselwe Eyakheke Ngokubandayo, I-Arc Ehlanganisiwe Ephindwe Kabili Ne-Spiral Seam Welded

Yethula:

Emhlabeni weipayipi lensimbiukukhiqiza, izindlela ezihlukahlukene zikhona zokukhiqiza amapayipi ahlangabezana nezidingo ezihlukahlukene zezimboni nezentengiso.Phakathi kwawo, amathathu agqame kakhulu amapayipi esakhiwo ashiselwe akhiwe ngendlela ebandayo, amapayipi ashiselwe i-arc anezingqimba ezimbili namapayipi ashiselwe ngomthungo.Indlela ngayinye inezinzuzo eziyingqayizivele kanye nokubi okumelwe kucatshangelwe lapho kukhethwa isisombululo esifanele samapayipi sephrojekthi ethile.Kule bhulogi, sizocubungula imininingwane yalezi zindlela zobuchwepheshe ezintathu zokukhiqiza amapayipi, sigxile ezicini zabo nasekusetshenzisweni kwazo.

1. Ipayipi lesakhiwo elakhiwe ngokubandayo:

Kuyabanda kwakheka ashiselwe isakhiwoipayipi, elivame ukufushaniswa njenge-CFWSP, lenziwa ngokubanda ukwakha ipuleti lensimbi noma umucu ube yisimo esiyisilinda bese ushisela imiphetho ndawonye.I-CFWSP yaziwa ngezindleko zayo eziphansi, ukunemba okuphezulu kobukhulu kanye nohlu olubanzi lwezinketho zosayizi.Lolu hlobo lwamapayipi luvame ukusetshenziswa ekusetshenzisweni kwesakhiwo njengokwakhiwa kwezakhiwo zezimboni, amabhuloho, nengqalasizinda.

2. Ipayipi elishiselwe i-arc elinezinhlangothi ezimbili:

I-arc ecwiliswe kabili eshiselweipayipi, elibizwa ngokuthi i-DSAW, liyipayipi elakhiwe ngokuphakela amapuleti ensimbi ngama-arc amabili ngesikhathi esisodwa.Inqubo yokushisela ihilela ukufaka i-flux endaweni yokushisela ukuze kuvikelwe insimbi encibilikisiwe, okuholela ekuhlanganyeleni okuhlala isikhathi eside futhi ukumelana nokugqwala.Amandla akhethekile wepayipi le-DSAW, ukufana okuhle kakhulu kanye nokumelana okuphezulu nezinto zangaphandle kuyenza ibe ilungele ukuthutha uwoyela, igesi namanzi kumaphrojekthi amakhulu wengqalasizinda.

3. Ipayipi elishiselwe umthungo:

Kuvunguza umthungo oshiselwe ipayipi, eyaziwa nangokuthi i-SSAW (i-spiral submerged arc welded) ipayipi, yenziwa ngokugoqa umucu wensimbi ogoqelwe oshisayo ube wumumo oyisipesheli bese ushisela imiphetho kusetshenziswa inqubo yokushisela engaphansi kwamanzi.Le ndlela ivumela ukuguquguquka okukhulu kububanzi bepayipi nokuqina kodonga.Amapayipi ashiselwe i-arc angaphansi kwe-Spiral anekhono elihle kakhulu lokugoba kanye nokuthwala umthwalo futhi asetshenziswa kakhulu ekuthuthweni koketshezi olufana nowoyela negesi yemvelo, alungele amapayipi amabanga amade kanye nezicelo zasolwandle.

Ekuphetheni:

Ukukhethwa kwamapayipi esakhiwo ashiselwe akhiwe ngendlela ebandayo, amapayipi ashiselwe i-arc anezingqimba ezimbili ezingaphansi, kanye namapayipi ashiselwe ngomthungo ovunguzayo kuncike ezidingweni ezithile kanye nezidingo zephrojekthi.Amashubhu esakhiwo ashiselwe akhiwe ngendlela ebandayo athandwa kakhulu ekusetshenzisweni kwesakhiwo ngenxa yokungabizi kwawo kanye nokunemba kwawo.Ipayipi elishiselwe i-arc elicwiliswe kabili lisebenza kahle kakhulu ekuthuthweni kukawoyela, igesi yemvelo namanzi ngenxa yamandla awo aphakeme nokunwebeka.Okokugcina, ipayipi elishiselwe i-spiral seam linekhono elihle kakhulu lokugoba kanye nokuthwala umthwalo, okulenza libe inketho esebenzayo yamapayipi amabanga amade namaphrojekthi asogwini.Ukuze wenze isinqumo esinolwazi, kubalulekile ukucabangela izici ezifana nezindleko, amandla, ukumelana nokugqwala kanye nezici zephrojekthi.Ngokuhlola ngokucophelela le mingcele, onjiniyela nabaphathi bephrojekthi bangakhetha ubuchwepheshe bokukhiqiza amapayipi obufaneleka kangcono izinhloso zabo zephrojekthi.
