Amapayipi Ahlanganisiwe E-Arc Ahlanganisiwe Angaphansi Komoya Embonini Yesimanje

Amapayipi Ahlanganisiwe E-Arc Afakwe Nge-Spiral Embonini Yesimanje Isithombe Esivelele

Incazelo emfushane:

Kuyo yonke indawo enkulu yemboni yesimanje, onjiniyela nochwepheshe bahlala befuna izixazululo ezingcono kakhulu zokuhlangabezana nezidingo ezahlukahlukene zengqalasizinda kanye nezokuthutha. Phakathi kobuchwepheshe obuningi bokukhiqiza amapayipi obutholakalayo,ipayipi elihlanganisiwe le-arc elicwiliswe ngaphansi kwamanzi elijikelezayo(SSAW) ivele njengokukhetha okuthembekile nokungabizi kakhulu. Le bhulogi ihlose ukukhanyisa izinzuzo nezinselele ezibalulekile ezihambisana nalobu buchwepheshe bokukhiqiza amapayipi obusha.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Izinzuzo zepayipi elihlanganisiwe le-arc elifakwe ngaphakathi eliyindilinga:

1. Ukwakhiwa okuphumelelayo:

Amapayipi e-SSAW anomklamo wokushisela ojikelezayo ovumela ukukhiqizwa okuphumelelayo kanye nesikhathi sokukhiqiza esincishisiwe. Lesi sici esiyingqayizivele senza kube ukukhetha kokuqala kwamaphrojekthi okwakha amakhulu njenge-oyili kanyeamapayipi kaphethiloli, izinhlelo zokudlulisa amanzi, kanye namapulatifomu okubhoboza asogwini lolwandle. Inqubo yokushisela eqhubekayo iqinisekisa izinga eliphezulu lokuqina kwesakhiwo, okwandisa ukuqina kanye nokuphila kwenkonzo yepayipi.

2. Amandla amahle kakhulu kanye nokuguquguquka:

Isakhiwo esijikelezayo sepayipi le-SSAW sandisa amandla alo, sivumela ukuthi limelane nezingcindezi zangaphandle nezangaphakathi. Lawa mapayipi ayakwazi ukumelana nezimo zomkhathi ezimbi kakhulu, okwenza afaneleke ukusetshenziswa ngaphezulu nangaphansi komhlaba. Ngaphezu kwalokho, ukuguquguquka kwamapayipi e-SSAW kwenza ukuthi avumelane kalula futhi afakwe ezindaweni ezahlukahlukene, kufaka phakathi izindawo ezimagebhugebhu kanye nenhlabathi engazinzile.

3. Isixazululo esingabizi kakhulu:

Izinqubo zokushisela eziqhubekayo zandisa umkhiqizo ngenkathi zinciphisa kakhulu amaphutha kanye nezindleko zokushisela. Ngaphezu kwalokho, amapayipi ashiselwe nge-arc acwiliswe ngaphansi kwe-spiral anikeza amandla nokuqina okuphezulu, anciphisa izindleko zokulungisa nokulungisa phakathi nesikhathi sawo sokuphila, okwenza kube ukukhetha okungabizi embonini.

Izinselele ezibhekene namapayipi ahlanganisiwe e-arc acwiliswe ngaphansi kwamanzi ajikelezayo:

1. Ukulawulwa kwekhwalithi:

Ngenxa yezinqubo eziyinkimbinkimbi zokushisela ezihilelekile ekukhiqizeni amapayipi ahlanganisiwe e-arc ac ac acwiliswe ngaphansi kwamanzi, ukuqinisekisa ikhwalithi ehambisanayo kuyinselele. Uma amapharamitha okushisela engalawulwa ngokunembile, kuzovela amaphutha okushisela njengokusikwa okungaphansi, ama-pores, kanye nokuntuleka kokuhlanganiswa. Ukuze kunqotshwe le nselele, izinyathelo zokulawula ikhwalithi eziqinile kanye nezinhlelo zokuqapha ezithuthukisiwe ngesikhathi senqubo yokukhiqiza zibalulekile.

2. Ububanzi bokukhawulelwa kobubanzi bepayipi:

Nakuba amapayipi ahlanganisiwe e-spiral ac welded arc afakwe emanzini afanele ukusetshenziswa kobubanzi obukhulu, angase angafaneleki ezimbonini ezidinga ubukhulu bamapayipi amancane. Inqubo yokukhiqiza isebenza kahle kakhulu kumapayipi amakhulu, okuholela ekutholakaleni okulinganiselwe kwamaphrojekthi amancane njengokusebenzisa amapayipi ezindaweni zokuhlala kanye nokusetshenziswa kwezimboni ezincane. Ngezidingo ezinjalo, kufanele kucatshangelwe ubuchwepheshe bokukhiqiza amapayipi obuhlukile.

3. Ukwembozwa kobuso:

Enye inselele ebhekene nemboni yamapayipi e-SSAW ukuqinisekisa ukuthi kunezimbozo zobuso ezifanele nezihlala isikhathi eside ukuze kuvikelwe ekugqwaleni nasekugugeni. Ukusetshenziswa kwembozo ezindaweni ezijikelezayo kudinga imishini ethuthukisiwe kanye nobuchwepheshe ukuqinisekisa ukumbozwa okulinganayo kanye nokunamathela. Imbozo yobuso efanele ibalulekile ekwandiseni impilo yenkonzo yamapayipi ahlanganisiwe e-arc ac acwiliswe ngaphansi kwamanzi, ikakhulukazi ezindaweni ezinzima.

Ekuphetheni:

Amapayipi ahlanganisiwe e-spiral ac welded ac welded abonakala ewubuchwepheshe obunenzuzo enkulu embonini yesimanje, enikeza ukusebenza kahle, amandla kanye nokusebenza kahle kwezindleko. Umthungo wawo oyingqayizivele we-spiral weld uvumela ukukhiqizwa okuphumelelayo kanye nokuqina okwandisiwe, okwenza ufanelekele amaphrojekthi amakhulu okwakha. Kodwa-ke, ukuze kuqhubeke impumelelo kanye nokwamukelwa kabanzi kwalolu buchwepheshe bokukhiqiza, izinselele ezifana nokulawulwa kwekhwalithi, ububanzi obulinganiselwe bobubanzi, kanye nokugqoka okungaphezulu kudingeka kuxazululwe. Ngokunqoba lezi zinselele ngokuthuthuka kwezobuchwepheshe kanye nokubambisana kwemboni, ipayipi elihlanganisiwe le-spiral ac welded linekusasa elithembisayo ekuguquleni nasekusekeleni ingqalasizinda ebalulekile emhlabeni jikelele.
