Kenyelletso ea kenyelletso ea tekheniki ea tjheseletsa ea qubu ea tšepe e sa hloekang ea corrosion.
Theknoloji ea ho tjheseletsa qubu e sebelisa welding ho fetola bokaholimo ba sesebediswa ho fihlela litlhoko tsa ts'ebetso ea sesebelisoa nakong ea ts'ebeletso. Ts'ebetso ea ho qhibiliha ha thapo ea khoele e phahame, masala a bonolo, ho phatloha ho nyane haholo, pampitšana ea welding e ntle, 'me e ka finyella welding e tsoelang pele le e tsitsitseng ka nako e telele, e ka ntlafatsang haholo katleho ea tlhahiso.
JINGLEI qubu tjheseletsa mantlha tjheseletsa terata
Hydrogenation reactor ka kakaretso e sebelisa tšepe ea CR-MO e le thepa ea substrate, 'me lihlahisoa tsa terata tsa tšepe tse sa hloekang tsa GFS-309L (transition layer) le GFS-347L (corrosion resistance) li sebelisoa haholo-holo bakeng sa lebota le ka hare le bokaholimo ba mochini.
GFS-309L+GFS-347L motsoako oa ho tjheseletsa qubu
● Mokhoa oa ho tjheseletsa ka pidium
Mohato ①:
Taba ea pele, GFS-309L e bokelloa holim'a thepa ea substrate e le lera la phetoho ho bapala karolo ea cushioning, e ka fokotsang monyetla oa ho phatloha ha welding ka mor'a moo.
Mohato ②:
Mekhahlelo e 'meli ea GFS-347L ea qubu ea welding e sebelisoa e le lera la kutu, 'me botenya bohle ba lera la phetoho + lera la kutu ke hoo e ka bang 7 ~ 8mm.
Mohato ③:
Ka mor'a ho cheseletsa mocheso oa mocheso (PWHT), moreki ea latelang o hloka 665 ° C × 12H + 705 ℃ × 32h e le mohlala.
Mohato ④:
O ile a etsa mochini oa tjheseletsa ka botenya bo hlokahalang.
