Isiciko sepayipi

Intsimbi engatyiwayo: 304 304L 316 316L 321 2520 310, 317, njl.

Intsimbi yekhabhoni: A234WPB, A420WPL6, WPHY52, WPHY60, WPJHY65, WPHY70 njl.

Ububanzi: DN15-DN2500

Ubukhulu bodonga: SCH5-SCH160
Imigangatho: ASME DIN JIS BS GB/T JB SH HG, ngolu hlobo lulandelayo: GB/T12459-2017, GB/T13401-2017, ASME B16.9, SH3408, SH3409, HG/T21635, DL/T695, SY/T0510, DIN2617
Ukusetyenziswa: amanzi, iziselo, ibhiya, ukutya, iikhemikhali zepetroli, amandla enyukliya, oomatshini, izixhobo zonyango, izichumisi, ukwakhiwa kweenqanawa, ukuthintela amanzi, imibhobho, njl.
Ukupakisha: ibhokisi yomthi, ibhokisi. Kuphephe ukutywina kwi-r yesigqubuthelo sesitya, okuya kunciphisa ukuncitshiswa kunye noxinzelelo oluphezulu. Xa udibanisa, iimfuno zesikhokelo somthungo wokutywina zivunyelwe kuphela ukuba zibe yi-radial kwaye zijikeleze. Ii-caps ezinkulu zinokususa le mfuneko kwixesha elizayo. Umgama wokutywina kufuneka ufuneke, ongaphezulu kwe-3δ kwaye ungabi ngaphantsi kwe-100mm (indawo yokutywina echaphazeleka bubushushu yindawo enoxinzelelo oluphezulu, kwaye ukwakheka kweekhemikhali kule ndawo kuya kutshiswa. Ke ngoko, kuyimfuneko ukuphepha indawo enoxinzelelo oluphezulu, enxulumene nobukhulu. .Ngokwamava asebenzayo, ubude bokubola koxinzelelo bukhulu kune-3δ kwaye bungabi ngaphantsi kwe-100mm). Nangona kunjalo, kunzima kwizixhobo zokufriji ukuhlangabezana nale mfuneko kwaye inobungcali bayo.
Isiciko sepayipi ye-Hemispherical
Emva kokudibanisa, intloko edibeneyo kunye ne-weld edibeneyo kufuneka zivavanywe nge-100% ye-ray okanye i-ultrasound, kwaye inqanaba lokufaneleka liza kulandela igobolondo lezixhobo. Inqanaba lokuhlola kunye nomlinganiselo we-weld seam yokugqibela eyenziweyo iyafana negobolondo lezixhobo, elichitha imali eninzi. Umzekelo: Ukuba igobolondo lezixhobo livavanyiwe nge-20%, i-III iyafaneleka. I-bulkhead splicing weld kunye ne-final weld nazo ziyafaneleka nge-III, kwaye i-welding joint coefficient yi-0.85;
Ukuba indlu yezixhobo ivavanyiwe ngokupheleleyo, u-II uyafaneleka. I-bulkhead splicing weld kunye ne-final weld nazo ziyafaneleka ngokupheleleyo, kwaye i-welding joint coefficient yi-1
Ngoko ke, nangona i-bulkhead splicing ivavanyiwe ngokupheleleyo, inqanaba leemfanelo lahlukile, kwaye lilandela igobolondo lezixhobo.
Kodwa nikela ingqalelo kwinkqubo yokwenziwa kwenkqubo:
Indlela echanekileyo yile: ukubhula (ukubhala) – iipleyiti ezincinci zidityaniswa zibe ziipleyiti ezinkulu – ukwenza – uvavanyo olungonakalisiyo
Ukuba akulunganga ukuvavanya ngaphambi kokubumba, umgangatho wemveliso emva kokubumba awunakuqinisekiswa. Oko kukuthi, uvavanyo olungonakalisiyo lubhekisa kuvavanyo lokugqibela olungonakalisiyo.
