1. Amanyathelo
Ngokwe-damumu yokuphakama enikezwe yinjineli yaseburhulumenteni, uphawula umgca wokuphakama kwindawo yodonga kunye nekholamu yesiseko apho kufuneka ifakwe khona umbhobho; faka iprayikhi yeparakhi kunye nomlindi ngokomzobo nenombolo; faka umbhobho ngokomzobo wokufakelwa kwemibhobho kunye nenani langaphambili lombhobho; Lungisa kunye nenqanaba lethambeka lombhobho, lungisa inkxaso yombhobho, kwaye ubeke umbhobho.
2.Izo
Umkhombandlela wethambeka kunye ne-gradient yombhobho kufuneka uhlangabezane neemfuno zoyilo; Ithambeka lombhobho linokuhlengahlengiswa yiplate exhasayo yentsimbi phantsi kwenkxaso, kwaye isishwankathelo sinokuhlengahlengiswa yi-boom bolt; Ipleyiti exhasayo kufuneka idlwengulwe ngamacandelo afakelweyo okanye isakhiwo sentsimbi, akufuneki ukuba sibanjwe phakathi kombhobho kunye nenkxaso.
Iiflethi, i-welds kunye nezinye iinxalenye eziDibeneyo kufuneka zilungiselelwe ukuhlolwa ngokulula nokulungiswa, kwaye akufuneki zisondele eludongeni, phantsi okanye kwisakhelo sombhobho.
Xa ipipeline ihambahamba i-Slab esemgangathweni, iya kufakwa ityhubhu yokukhusela, kwaye ityhubhu yokukhusela iya kuba yi-50mm ngaphezulu komhlaba.
Xa ipipeline ihambahamba i-Slab esemgangathweni, iya kufakwa ityhubhu yokukhusela, kwaye ityhubhu yokukhusela iya kuba yi-50mm ngaphezulu komhlaba.
Ifom kunye nokuphakanyiswa kwenkxaso kunye ne-hanger kufuneka ihambelane neemfuno zemizobo, kwaye indawo yokulungisa kunye nendlela yokulungisa kufuneka ihambisane noyilo kwaye ifihlakele kwaye iqinile kwaye iqinile.
Imiqolo ye-therpines okanye imibhobho ethe nkqo kufuneka icoceke, kwaye izikhundla zofakelo lwevelve kwimiqolo yemibhobho kufuneka ihambelane.
I-3. Ukufakwa
Ukufakwa kwe-Pipeline yahlulwe yangamaqhekeza kunye neziqwenga. Umbhobho ophambili kuqala, emva koko umbhobho wesebe. Umbhobho wesebe ukusuka kumbhobho ophambili kufuneka ufakelwe emva kokuba umbhobho omkhulu ubekwe. Inkwenkwezi yenkulungwane yaziswa ukuba imibhobho edityaniswe kwizixhobo kufuneka yenziwe emva kokuba izixhobo zikhutshiwe.
Unxibelelwano lwefleni kufuneka lube lugxingqwa ngombhobho, kwaye iflethi kufuneka ihambelane. Ukuphambuka akufuneki kube ngaphezulu kwe-1.5% yobubanzi beflethi yeflethi kwaye ingabi ngaphezu kwe-2mm. Imingxunya yeBolt kufuneka iqinisekise ukuba iibhotile zingena ngokukhululekileyo, kwaye iibhloko akufuneki zingeniswe ngeendlela ezinyanzelekileyo. .
Iindiza ezimbini ze-gasket kufuneka zibethe tyaba kwaye zicocekile, kwaye akufuneki zibekho ukoyikwa kwe-radic.
Unxibelelwano lwefleni kufuneka lusebenzise iibhloko zenkcazo efanayo, kwaye isikhokelo sokufakwa kufuneka sifane. Xa i-gazist iyafuneka, i-bolt nganye ayifanele ingadlulanga enye, kunye neebhanti kunye namantongomane emva kokuqinisa kufuneka zingagungqi.
