Botenya ba lebota: SCH5-SCH160
Tekanyetso: ASME DIN JIS BS GB/T JB SH HG, ka tsela e latelang: GB/T12459-2017, GB/T13401-2017, ASME B16.9, SH3408, SH3409,HG/T21635,DL/T695,SY7,DIN10
Lisebelisoa: metsi, lino, biri, lijo, lik'hemik'hale tsa petrole, matla a nyutlelie, mechine, lisebelisoa tsa bongaka, menontsha, ho haha ​​​​likepe, ho thibela metsi, liphaephe, joalo-joalo.
Ho paka: lebokose la lepolanka, lebokose Qoba splicing ka r ea sekoahelo sejana, e leng tla fokotsa thinning le khatello ea kelello e phahameng. Ha o kopanya, litlhoko tsa tataiso ea seam ea welding li lumelloa feela ho ba radial le circumferential. Li-caps tse kholo li ka tlosa tlhoko ena nakong e tlang. Sebaka sa splicing se lokela ho hlokoa, se seholo ho feta 3δ mme eseng ka tlase ho 100mm (sebaka se amehileng ke mocheso ke sebaka se nang le khatello e matla, 'me lik'hemik'hale sebakeng sena li tla chesoa. Ka hona, hoa hlokahala ho qoba sebaka se nang le khatello e phahameng ea maikutlo, se amanang le botenya. Leha ho le joalo, ho thata hore lisebelisoa tsa sehatsetsi li finyelle tlhokahalo ena 'me li na le khethollo ea tsona.

Kamora ho kopanngoa, hlooho e kopantsoeng le weld e kopantsoeng e lokela ho lekoa ka 100% ray kapa ultrasonic, 'me boemo ba thuto bo tla latela khetla ea lisebelisoa. Boemo ba tlhahlobo le karo-karolelano ea seam ea ho qetela e entsoeng ka weld e tšoana le khetla ea thepa, e senyang haholo. Mohlala: Haeba khetla ea thepa e lekoa ka 20%, III e tšoaneleha. The bulkhead splicing weld le weld ho qetela ba boetse ba III tšoaneleha, 'me tjheseletsa kopanelo coefficient ke 0,85;
Haeba ntlo ea thepa e lekoa ka 100%, II e tšoaneleha. The bulkhead splicing weld le weld ea ho qetela le tsona lia tšoaneleha II, 'me coefficient e kopanetsoeng ea welding ke 1.
Ka hona, le hoja splicing ea bulkhead e lekoa ka 100%, boemo ba thuto bo fapane, 'me bo latela khetla ea thepa.
Empa ela hloko ts'ebetso ea tlhahiso ea ts'ebetso:
Mokhoa o nepahetseng ke: ho koala (ho ngola) - lipoleiti tse nyane li bokelloa ka lipoleiti tse kholo - ho theha - tlhahlobo e sa senyeheng.
Haeba ho fosahetse ho hlahloba pele ho bōptjoa, boleng ba sehlahisoa ka mor'a ho bōptjoa bo ke ke ba tiisetsoa. Ke ho re, teko e sa senyeheng e bolela teko ea ho qetela e sa senyeheng.
