    Ukufakwa kwamapayipi e-ASTM A234 WPB & WPC kufaka phakathi izindololwane, i-tee, nezinciphisi

    Incazelo emfushane:

    Le ncazelo ihlanganisa ukufakwa kwensimbi yekhabhoni ebhakiwe kanye nensimbi ye-alloy eyakhiwe ngaphandle kokufaka okuhlanganisiwe. Lokhu kufakwa kusetshenziselwa ukufaka amapayipi okucindezela kanye nokwakhiwa kwemikhumbi yokucindezela ukuze kusetshenzwe emazingeni okushisa aphakathi naphezulu. Izinto zokufakwa kufanele zibe yinsimbi ebulewe, izinto zokufakelwa, imigoqo, amapuleti, imikhiqizo yeshubhu engenamthungo noma ehlanganisiwe enensimbi yokugcwalisa eyengeziwe. Imisebenzi yokufakelwa noma yokubumba ingenziwa ngokufaka i-hammer, ukucindezela, ukubhoboza, ukukhipha, ukugudluza, ukugoba, ukushisela okuhlanganisiwe, ukwenza imishini, noma ngokuhlanganiswa kwemisebenzi emibili noma ngaphezulu. Inqubo yokwakha kufanele isetshenziswe ngendlela yokuthi ngeke iveze ukungapheleli okulimazayo ezifakweni. Ukufakwa, ngemva kokwakheka ekushiseni okuphezulu, kufanele kupholiswe kufike ezingeni lokushisa elingaphansi kwebanga elibalulekile ngaphansi kwezimo ezifanele ukuvimbela amaphutha alimazayo abangelwa ukupholisa okusheshayo kakhulu, kodwa hhayi ngokushesha kakhulu kunezinga lokupholisa emoyeni othulile. Ukufakwa kuzohlolwa ukucindezelwa, ukuhlolwa kobulukhuni, kanye nokuhlolwa kwe-hydrostatic.

    Ukukhiqiza

    Ukufakwa kwamapayipi ensimbi yekhabhoni i-ASTM A234 kungenziwa ngamapayipi angenamthungo, amapayipi noma amapuleti ahlanganisiwe ngokubumba imisebenzi yokucindezela, ukubhoboza, ukukhipha, ukugoba, ukushisela okuhlanganisiwe, ukwenza imishini, noma ngokuhlanganiswa kwale misebenzi emibili noma ngaphezulu. Wonke ama-weld kufaka phakathi ama-weld emikhiqizweni yeshubhu lapho kwenziwa khona ukuhlanganiswa kufanele enziwe ngokuhambisana ne-ASME Section IX. Ukwelashwa kokushisa ngemuva kokushisela ku-1100 kuya ku-1250°F[595 kuya ku-675°C] kanye nokuhlolwa kwe-x-ray kufanele kwenziwe ngemuva kwenqubo yokushisela.
