Ukusetyenziswa: amanzi, iziselo, ibhiya, ukutya, iikhemikhali zepetroli, amandla enyukliya, oomatshini, izixhobo zonyango, izichumisi, ukwakha iinqanawa, ukuthintela amanzi, imibhobho, njl.
Ukupakisha: ibhokisi yomthi, ibhokisi Kuphephe splicing kwi r isitya cap, nto leyo eya kunciphisa thinning kunye noxinzelelo oluphezulu.Xa udibanisa, iimfuno zolwalathiso lwe-welding seam zivunyelwe kuphela ukuba zibe yi-radial kunye ne-circumferential.Iminqwazi emikhulu ingasusa le mfuneko kwixesha elizayo.Umgama we-splicing kufuneka ufuneke, ongaphezu kwe-3δ kwaye ungabi ngaphantsi kwe-100mm (indawo ye-welding echatshazelwe bubushushu yindawo enoxinzelelo oluphezulu, kwaye ukwakheka kweekhemikhali kule ndawo kuya kutshiswa. Ngoko ke, kuyimfuneko ukuphepha indawo enoxinzelelo oluphezulu, enxulumene nobungqingqwa .Ngokuvumelana namava asebenzayo, ubude boxinzelelo lokubola bukhulu kuno-3δ kwaye bungekho ngaphantsi kwe-100mm).Nangona kunjalo, kunzima kwisixhobo sefriji ukuhlangabezana nale mfuneko kwaye inomsebenzi wayo.
Hemispherical Pipe cap
Emva kokudibanisa, intloko edibeneyo kunye ne-weld edibeneyo kufuneka ibe yi-100% ray okanye i-ultrasonic ihlolwe, kwaye inqanaba lesiqinisekiso liya kulandela iqokobhe lesixhobo.Inqanaba lokuhlola kunye nomlinganiselo we-weld seam yokugqibela eyenziweyo iyafana neqokobhe lesixhobo, esimosha kakhulu.Umzekelo: Ukuba iqokobhe lesixhobo livavanyiwe ngama-20%, i-III ifanelekile.I-bulkhead splicing weld kunye ne-weld yokugqibela nayo i-III ifanelekile, kwaye i-welding joint coefficient yi-0.85;
Ukuba izixhobo zezindlu zivavanyiwe nge-100%, i-II ifanelekile.I-bulkhead splicing weld kunye ne-weld yokugqibela nayo i-II ifanelekile, kunye ne-welding joint coefficient yi-1.
Ke ngoko, nangona i-bulkhead splicing ivavanywa nge-100%, inqanaba lesiqinisekiso lahlukile, kwaye lilandela iqokobhe lesixhobo.
Kodwa qaphela inkqubo yokuvelisa:
Indlela echanekileyo yile: ukuvala (ukubhala) - iipleyiti ezincinci zihlanganiswe kwiipleyiti ezinkulu - ukwenza - ukuvavanywa okungonakalisi
Ukuba akulunganga ukuvavanya phambi kokubumba, umgangatho wemveliso emva kokubumba awunakuqinisekiswa.Oko kukuthi, uvavanyo olungonakalisi lubhekisa kuvavanyo lokugqibela olungonakalisi.
