Ukuhlaziywa Okuqhathanisayo Kwamapayipi Ahlanganisiwe Ahlanganisiwe Abandayo, Ahlanganisiwe Kabili Ahlanganisiwe Ahlanganisiwe Ahlanganisiwe Futhi Ahlanganisiwe Ahlanganisiwe Ahlanganisiwe Ahlanganisiwe Ajikelezayo

Yethula:

Ezweni le-ipayipi lensimbiEkwenzeni izinto zokukhiqiza, kunezindlela ezahlukahlukene zokukhiqiza amapayipi ahlangabezana nezidingo ezahlukene zezimboni nezentengiselwano. Phakathi kwazo, ezintathu ezivelele kakhulu amapayipi esakhiwo ahlanganisiwe abandayo, amapayipi ahlanganisiwe e-arc angaphansi kwezingqimba ezimbili kanye namapayipi ahlanganisiwe e-spiral seam. Indlela ngayinye inezinzuzo kanye nokungalungi okuhlukile okumele kucatshangelwe lapho kukhethwa ikhambi elifanele lamapayipi lephrojekthi ethile. Kule bhulogi, sizohlola imininingwane yalezi zindlela ezintathu zobuchwepheshe bokukhiqiza amapayipi, sigxile ezicini zazo kanye nezicelo zazo.

1. Ipayipi lesakhiwo elihlanganisiwe elenziwe ngokubandayo:

Umkhuhlane isakhiwo esihlanganisiwe esakhiweIpayipi, elivame ukufushaniswa ngokuthi i-CFWSP, lenziwa ngepuleti lensimbi noma umcu obandayo obumba isimo esiyindilinga bese uhlanganisa imiphetho ndawonye. I-CFWSP yaziwa ngezindleko zayo eziphansi, ukunemba kwayo okuphezulu kanye nezinketho eziningi zosayizi. Lolu hlobo lwepayipi luvame ukusetshenziswa ezindleleni zokwakha ezifana nokwakhiwa kwezakhiwo zezimboni, amabhuloho, kanye nengqalasizinda.

2. Ipayipi elihlanganisiwe le-arc elicwiliswe emaceleni amabili:

I-arc ecwiliswe kabili ehlanganisiweIpayipi, elibizwa ngokuthi i-DSAW, liyipayipi elakhiwe ngokufaka amapuleti ensimbi ngama-arc amabili ngesikhathi esisodwa. Inqubo yokushisela ihilela ukufaka i-flux endaweni yokushisela ukuvikela insimbi encibilikisiwe, okuholela ekuhlanganeni okuhlala isikhathi eside futhi okumelana nokugqwala. Amandla akhethekile epayipi le-DSAW, ukufana okuhle kakhulu kanye nokumelana okuphezulu nezinto zangaphandle kwenza kube kuhle kakhulu ekuthuthweni kukawoyela, igesi namanzi kumaphrojekthi amakhulu engqalasizinda.

3. Ipayipi elihlanganisiwe lomthungo ojikelezayo:

Ipayipi elihlanganisiwe lomthungo ojikelezayo, eyaziwa nangokuthi ipayipi le-SSAW (i-spiral submerged arc welded), lenziwa ngokugoqa umugqa wensimbi ogoqwe ngokushisa ube yisimo esijikelezayo bese ugoqa imiphetho kusetshenziswa inqubo yokugoqa i-arc engaphansi komhlaba. Le ndlela ivumela ukuguquguquka okukhulu kobubanzi bepayipi kanye nobukhulu bodonga. Amapayipi ahlanganisiwe e-arc angaphansi komhlaba aqinile anamakhono amahle okugoba nokuthwala umthwalo futhi asetshenziswa kabanzi ekuthuthweni koketshezi njengowoyela negesi yemvelo, afanelekela amapayipi amabanga amade kanye nezicelo zasogwini lolwandle.

Ekuphetheni:

Ukukhethwa kwamapayipi esakhiwo ahlanganisiwe abandayo, amapayipi ahlanganisiwe angaphansi kwe-arc aphindwe kabili, kanye namapayipi ahlanganisiwe ahlanganisiwe ajikelezayo kuncike ezidingweni nasezidingweni ezithile zephrojekthi. Amapayipi esakhiwo ahlanganisiwe ahlanganisiwe abandayo ayathandwa ekusetshenzisweni kwesakhiwo ngenxa yokusebenza kahle kwezindleko zawo kanye nokunemba kwawo okulinganayo. Ipayipi elihlanganisiwe elingaphansi kwe-arc eliphindwe kabili lihamba phambili ekuthuthweni kukawoyela, igesi yemvelo kanye namanzi ngenxa yamandla alo aphezulu kanye nokunwebeka. Okokugcina, ipayipi elihlanganisiwe elihlanganisiwe elingaphansi kwe-spiral linamandla amahle okugoba nokuthwala umthwalo, okwenza kube inketho efanelekile yamapayipi akude kanye namaphrojekthi asogwini. Ukuze wenze isinqumo esinolwazi, kubalulekile ukucabangela izici ezifana nezindleko, amandla, ukumelana nokugqwala kanye nemininingwane yephrojekthi. Ngokuhlola ngokucophelela la mapharamitha, onjiniyela kanye nabaphathi bephrojekthi bangakhetha ubuchwepheshe bokukhiqiza amapayipi obufanelana kahle nezinhloso zabo zephrojekthi.
