Ipayipi lenqubo lidlala indima ebalulekile emandleni, kumakhemikhali, ku-petrochemical, metallurgy namanye amayunithi okukhiqiza. Inqubo yokufaka ihlobene ngokuqondile nekhwalithi yephrojekthi kanye namandla okuphepha. Ekufakweni kwepayipi lenqubo, ubuchwepheshe bepayipi lenqubo yiphrojekthi enezidingo eziphezulu zobuchwepheshe kanye nenqubo yokufaka eyinkimbinkimbi kakhulu. Izinga lokufakwa kwamapayipi lithinta ngqo ikhwalithi yenqubo yokuthutha, alithinti kuphela inqubo yokuthutha umkhiqizo, kodwa futhi lidlala indima enkulu emsebenzini. Ngakho-ke, ekufakweni kwepayipi lenqubo yangempela, ikhwalithi yokufaka kufanele ilawulwe. Leli phepha lidingida futhi lichaze ngokulawulwa kokufakwa kwamapayipi kanye nezinkinga okufanele zinakwe emkhakheni wokufakwa kwamapayipi eChina.
Ipayipi lomoya elicindezelwe
Ukulawulwa kwekhwalithi yokufakwa kwamapayipi enqubo e-China ikakhulukazi kuhlanganisa: isigaba sokulungiselela ukwakhiwa, isigaba sokwakha, isigaba sokuhlola, ukuhlolwa kokuhlolwa, ukuhlanzwa kwamapayipi kanye nesiteji sokuhlanza. Ngokukhula kwezidingo zobuchwepheshe, ekwakhiweni kwangempela, kufanele silungiselele, sifake, silawule futhi sinqande ukugqwala ngokwesimo sangempela.
1. Nquma uhlelo lokufakwa kwepayipi lenqubo
Ngaphambi kokuba kunqunywe ukufakwa kwepayipi lenqubo, amanani ayisisekelo okufakwa nokwakhiwa kwephrojekthi kufanele achazwe ngokuvumelana nezimo zendawo yokufaka nokwakhiwa kanye nomklamo wokwakha. Izinsiza eziyinhloko zabantu nezinto ezibonakalayo zokwakhiwa zizoqinisekiswa ngokulawula sonke isimo sokuthuthukiswa kwephrojekthi kanye nempahla eyinhloko nezinsiza zabantu zeyunithi yokwakha. Ngokuhlelwa kwesistimu yezinto ezibonakalayo kanye nabasebenzi, ukwabiwa okuphelele kuyenziwa. Ngaphansi kombandela wokuqinisekisa inqubekelaphambili yokwakha, inqubo ehambisanayo izohlelwa futhi ihlelwe ukuze kugcinwe abasebenzi bokwakha futhi kulwele isikhathi sokwakha, ukuze kuthuthukiswe ukusebenza kahle kwemishini emikhulu efana nokhreyini.
Njengephuzu eliyinhloko lokulungiselela uhlelo lokwakha, uhlelo lobuchwepheshe ikakhulukazi luhlanganisa: uhlelo olunembile lokuphakamisa kanye nesicelo senqubo yokushisela. Lapho kushiselwa izinto ezikhethekile kanye nokuphakanyiswa kwamapayipi anobubanzi obukhulu, incazelo yobuchwepheshe yohlelo lokwakha kufanele ithuthukiswe, futhi isisekelo sokuqondisa esiqondile sizothathwa njengesisekelo sokwakhiwa nokufakwa kwesayithi. Okwesibili, ngokuya ngohlelo lokuqukethwe lokuqukethwe nezinyathelo zokuqinisekisa ukuphepha, uhlelo lokwakha lunganqunywa ngokuhlanganisa zonke izici zezinto, futhi isiza sizoqondiswa ngokufanele nangokuhlelekile ukuze kwakhiwe okuhambisanayo.
2. Ukusetshenziswa kobuchwepheshe bokwenza amaphayiphi ekwakhiweni
Njengenqubo evamile eShayina, inqubo yokwakhiwa kwephayiphi kusengaphambili kufanele inakwe ngenxa yokujula okungaphelele kokwakhiwa kanye nenani eliphansi lokwenziwa ngaphambilini. Isibonelo, amanye amaphrojekthi wokwakha aphakamisa ukuthi ukwakhiwa kwamapayipi kufanele kube ngaphezu kuka-40%, okuthuthukisa kakhulu ubunzima bezinkampani zokwakha ngokusho kwesimo sangempela. Njengesixhumanisi esiyisihluthulelo sokufakwa kwamapayipi enqubo, ukujula kokwenziwa kusese kuyinqubo elula yokwenziwa emabhizinisini amaningi e-China. Isibonelo, inqubo yokwakhiwa kwangaphambili kwesigaba sepayipi eqondile ngendololwane kanye nepayipi ukuxhumana okubili futhi umuntu angaxazulula inkinga yokufaka elula yepayipi yenqubo. Uma imishini yokubhobhoza ifakiwe, ayikwazi ukudlala indima yokwakhiwa kwamapayipi. Ngakho-ke, ekwakhiweni kwangempela, kufanele sicabangele inqubo yokwakha kusengaphambili, futhi sifake igobolondo elihambisanayo elakhiwe endaweni yokufaka i-mercury ne-heat exchanger ngaphansi kwemibandela. Epayipini lokuhlanganisa lensimu elifanisiwe, lapho umhlangano wensimu usuqediwe, amajoyinti okushisela eqembu lensimu elingisiwe adonselwa emuva esitshalweni esihambisanayo sokwenza izinto, futhi okokusebenza okuzenzakalelayo kusetshenziselwa ukushisela, futhi i-flange ehambisanayo ixhunywe ngamabhawodi. . Ngakho-ke, umsebenzi we-welding manual endaweni yokwakha ungasindiswa futhi ukusebenza kahle kokufakwa kwepayipi kungathuthukiswa.
