Izinzuzo Zamapayipi Esakhiwo Ahlanganisiwe Ahlanganisiwe Abandayo

Incazelo emfushane:

Le ncazelo ihlanganisa amazinga amahlanu epayipi lensimbi elihlanganisiwe elenziwe ngogesi elihlanganisiwe (i-arc). Leli payipi lenzelwe ukudlulisa uketshezi, igesi noma umhwamuko.

Ngemigqa yokukhiqiza engu-13 yamapayipi ensimbi ajikelezayo, i-Cangzhou Spiral Steel pipes group Co., Ltd. iyakwazi ukukhiqiza amapayipi ensimbi ane-helical-seam anobubanzi obungaphandle obusukela ku-219mm kuya ku-3500mm kanye nobukhulu bodonga obufika ku-25.4mm.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Emikhakheni yokwakha neyokukhiqiza, ukukhethwa kwezinto zokushisela nezindlela kudlala indima ebalulekile ekuqedeni ngempumelelo kwanoma yimuphi umsebenzi. Enye yezinto ezinjalo eziye zathandwa eminyakeni yamuva nje ipayipi lesakhiwo elihlanganisiwe elenziwe ngendlela ebandayo. Lo mkhiqizo omusha unikeza izinzuzo eziningana ngaphezu kwamapayipi endabuko angenamthungo noma ahlanganisiwe, ikakhulukazi amapayipi omthungo ajikelezayo.

Umkhuhlane isakhiwo esihlanganisiwe esakhiweIpayipi lenziwa ngenqubo yokwakha ubanda, ehilela ukugoba nokwenza ama-coil ensimbi abe yisimo esifunwayo. Umphumela uba ipayipi eliqinile nelihlala isikhathi eside, kodwa elilula futhi elilula ukulisebenzisa. Ngaphezu kwalokho, inqubo yokwakha ubanda iqinisekisa ukuthi ipayipi ligcina ubuqotho besakhiwo salo kanye nokunemba kobukhulu, okwenza libe yindawo ekahle kakhulu ekusetshenzisweni kokushisela.

Ukuhlolwa Kwamanzi

Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwepayipi ukucindezeleka okungaphansi kuka-60% wamandla amancane okukhiqiza ashiwo ekushiseni kwegumbi. Ukucindezela kuzonqunywa yi-equation elandelayo:
P=2St/D

Izinguquko Ezivumelekile Ezisindweni Nasezilinganisweni

Ubude bepayipi ngalinye kufanele bulinganiswe ngokwehlukana futhi isisindo salo akumele sihluke ngaphezu kuka-10% noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, esibalwa kusetshenziswa ubude balo kanye nesisindo salo ngobude beyunithi ngayinye.
Ububanzi bangaphandle akumele buhluke ngaphezu kuka-±1% kobubanzi obujwayelekile bangaphandle obubekiwe.
Ubukhulu bodonga nganoma yisiphi isikhathi akumele bube ngaphezu kuka-12.5% ngaphansi kobukhulu bodonga obubekiwe.

Ubude

Ubude obungahleliwe obubodwa: 16 kuya ku-25ft (4.88 kuya ku-7.62m)
Ubude obuphindwe kabili obungahleliwe: ngaphezu kwamafidi angu-25 kuya ku-35 (7.62 kuya ku-10.67m)
Ubude obufanayo: ukuhlukahluka okuvunyelwe ±1in

Ukuphela

Izinqwaba zamapayipi kumele zifakwe iziphetho ezingenalutho, bese kuthi izimbobo ezisemaphethelweni zisuswe.
Uma ukuphela kwepayipi okuchazwe ukuthi kube yiziphetho ze-bevel, i-engeli kufanele ibe ngama-degree angu-30 kuya kwangu-35.

Enye yezinzuzo eziyinhloko zesakhiwo esihlanganisiwe esenziwe ngokubandayoipayipi lokushiselayikhono layo lokubekezelela amazinga okushisa aphezulu kanye nokucindezela. Ngokungafani namapayipi endabuko, asengozini yokugqwala kanye nezinye izinhlobo zokuwohloka, amapayipi akhiwe ngamakhaza aklanywe ukuze amelane nobunzima bokushisela kanye nezinye izinqubo zezimboni. Lokhu kuwenza afaneleke ukusetshenziswa ezinhlotsheni ezahlukahlukene zezicelo kusukela ekwakhiweni kwezakhiwo kuya kumaphrojekthi engqalasizinda.

Enye inzuzo yepayipi lesakhiwo elihlanganisiwe elenziwe ngokubandayo ukuthi lisebenza kahle kakhulu. Inqubo yokwakha ebandayo ingakhiqiza amapayipi ngobukhulu obuhlukahlukene kanye nezimo, okunciphisa isidingo sezinqubo zokubumba nezokugaya ezibizayo. Lokhu kwenza umkhiqizo ube shibhile futhi uthembeke njengepayipi elingenamthungo noma elihlanganisiwe. Ngaphezu kwalokho, uhlobo olulula lwepayipi elenziwe ngokubandayo lwenza ukuthuthwa nokufakwa kube lula futhi kube ngcono, okwandisa ukukhanga kwalo.

Amapayipi omthungo ajikelezayo azuza kakhulu enkambisweni yokwakha amakhaza. Amandla angokwemvelo kanye nokuguquguquka kwamapayipi abandayo kwenza abe yindawo ekahle yokwakha amajoyinti ajikelezayo aqinile futhi angavuzi. Lokhu kuwenza abe ukukhetha okuhle kakhulu kwezicelo ezifana nezinhlelo zokudonsa amanzi ngaphansi komhlaba, imigqa yamanzi ngisho nezinhlelo zokunisela zezolimo. Ngaphezu kwalokho, ubuso obubushelelezi bamapayipi abandayo bunciphisa ingozi yokungqubuzana nokuguguleka, kwandise impilo yamapayipi futhi kunciphise isidingo sokulungiswa nokulungiswa.

Sekukonke, ipayipi lesakhiwo elihlanganisiwe elibandayo linikeza izinzuzo eziningana ezenza kube ukukhetha okuhle kakhulu kokusetshenziswa kokushisela, ikakhulukazi ipayipi lomthungo elijikelezayo. Amandla alo, ukuqina kanye nokusebenza kahle kwezindleko kubenza babe ukukhetha okukhangayo kwezimboni eziningi, kusukela ekwakheni kuya ekukhiqizeni. Njengoba isidingo sezinto ezisezingeni eliphezulu nezithembekile siqhubeka nokukhula, ipayipi lesakhiwo elihlanganisiwe elihlanganisiwe elibandayo lizoba ukukhetha okuthandwa kakhulu kokusetshenziswa kokushisela.
