1. Izinyathelo
Ngokwedatha yokuphakama enikezwe ubunjiniyela bomphakathi, maka umugqa wedatha wokuphakama odongeni kanye nekholomu yesisekelo lapho ipayipi lidinga ukufakwa khona;faka ubakaki wepayipi kanye ne-hanger ngokomdwebo nenombolo;faka ipayipi ngokomdwebo wokufakwa kwepayipi kanye nenombolo esele yepayipi;Lungisa futhi ulinganise umthambeka wepayipi, lungisa ukusekela kwepayipi, futhi ubeke ipayipi.
2.Cela
Isiqondiso semithambeka kanye negradient yepayipi kufanele ihlangabezane nezidingo zokuklama;umthambeka wepayipi ungalungiswa ngepuleti lokusekela lensimbi ngaphansi kokusekela, futhi i-hanger ingalungiswa nge-boom bolt;ipuleti yokusekela kufanele ihlanganiswe nezingxenye ezishunyekiwe noma isakhiwo sensimbi, Akufanele ibanjwe phakathi kwepayipi nokusekela.
Ama-flanges, ama-welds nezinye izingxenye zokuxhuma kufanele zihlelwe ukuze zihlolwe kalula futhi zilungiswe, futhi akufanele zibe seduze nodonga, phansi noma uhlaka lwamapayipi.
Lapho ipayipi linqamula i-slab yaphansi, kufanele kufakwe ishubhu elivikelayo, futhi ishubhu elivikelayo libe ngama-50mm ngaphezu komhlaba.
Lapho ipayipi linqamula i-slab yaphansi, kufanele kufakwe ishubhu elivikelayo, futhi ishubhu elivikelayo libe ngama-50mm ngaphezu komhlaba.
Ifomu kanye nokuphakama kokusekela kanye ne-hanger kufanele kuhambisane nezidingo zemidwebo, futhi indawo yokulungisa kanye nendlela yokulungisa kufanele ihambisane nomklamo futhi ibe flat futhi iqine.
Imigqa yamapayipi avundlile noma aqondile kufanele icoceke, futhi izindawo zokufakwa kwamavalvu emigqeni yamapayipi kufanele zilingane.
3. Ukufakwa
Ukufakwa kwamapayipi kuhlukaniswe ngamasistimu nezicucu.Ipayipi eliyinhloko kuqala, bese kuba ipayipi legatsha.Ipayipi legatsha elisuka epayipini elikhulu kufanele lifakwe ngemva kokuba ipayipi elikhulu libekwe.I-Century Star yethula ukuthi ipayipi elixhunywe emshinini kufanele wenziwe ngemva kokuba impahla isilinganisiwe.
Ukuxhuma kwe-flange kufanele kugxile epayipini, futhi ama-flange kufanele ahambisane.Ukuphambuka akufanele kube ngaphezu kuka-1.5% we-diameter yangaphandle ye-flange futhi kungabi ngaphezu kuka-2mm.Izimbobo ze-bolt kufanele ziqinisekise ukuthi ama-bolts angangena ngokukhululekile, futhi ama-bolts akufanele afakwe ngezindlela eziphoqelelwe..
Izindiza ezimbili ze-gasket kufanele zibe flat futhi zihlanzeke, futhi akufanele kube khona imihuzuko ye-radial.
Ukuxhumeka kwe-Flange kufanele kusebenzise ama-bolts okucaciswa okufanayo, futhi isiqondiso sokufaka kufanele sifane.Uma kudingeka ama-gaskets, ibhawudi ngalinye akufanele lidlule elilodwa, futhi ama-bolts namantongomane ngemva kokuqinisa kufanele ahlanzwe.
