Bonnet ea Velve ea Heke ea tšepe e entsoeng ka Carbon

Bonnet ea valve ea heke ea tšepe e entsoeng ka tšepe e boima e entsoeng ho ASTM A105 / ASTM A350 LF2. E etselitsoe lipeipi tsa Class 300 le Class 600 tsa khatello e phahameng. Moralo oa bolted oa bonnet o nang le libaka tse tiisang ka mochini o nepahetseng. Mekhabiso e tloahelehileng e amohetsoe.

Tlhaloso e Feletseng ea Sehlahisoa: Bonnet ea valve ea heke ke karolo ea bohlokoa ea ho boloka khatello e lokelang ho mamella khatello e feletseng ea line le khatello ea mocheso oa cyclic. Libone tsa rona tsa tšepe tse entsoeng ka tšepe li hlahisoa ka theknoloji ea ho fereka e koetsoeng ho fihlela phallo e phahameng ea lijo-thollo, ho felisa kotsi ea porosity e teng mekhoeng e meng e thehiloeng ho lahla.

Bonnet e 'ngoe le e' ngoe e entsoe ka lichelete tsa ASTM A105 kapa ASTM A350 LF2 (tšebeletso ea mocheso o tlase), e tloaelehileng le e itekanetseng ho latela litlhoko tsa ASTM A788. CNC machining e netefatsa ho nepahala ha sefahleho sa flange (≤ 0.05 mm), bore concentricity, le khoele e nepahetseng bakeng sa sebaka sa ho paka kutu.

Moralo oa bolted oa bonnet o amohela likhase tse tloaelehileng tsa graphite tsa spiral-leqeba 'me o amohela lisebelisoa tse tloaelehileng tsa ho paka (PTFE, graphite, ntle le asbestos). E fumaneha bakeng sa li-valve tsa heke tse 2" ho isa ho tse 24" tse nang le likhetho tse tloaelehileng kapa tse atolositsoeng tsa molala oa bonnet.

Likarolo tsa Bohlokoa:

• Forging process: Closed-die hot forging - sebopeho se phahameng sa lijo-thollo, bophelo bo phahameng ba mokhathala
• Boitsebiso: ASTM A105 (e tloaelehileng) / ASTM A350 LF2 (tšebeletso ea mocheso o tlase -46°C)
• Phekolo ea mocheso: E tloaelehileng + e halefile (N + T) ka litlhoko tsa ASTM A105
• Machining: CNC e felletseng - sefahleho sa flange, bore, khoele, kamore ea ho paka
• NDE: UT (tlhahlobo ea ultrasonic) holim'a tsohle tse thata tsa forgings; MT (magnetic particle) ka kopo
• Taolo e lumellanang le boima ba NACE MR0175 e fumanehang bakeng sa ts'ebeletso e bolila
• Tekanyetso ea boholo: ASME B16.34, API 600

Litlhaloso:

Liindasteri tsa Likopo:

• Oli le khase holimo / bohareng / tlase
• Limela tsa ho hloekisa le tsa petrochemical
• Ho hlahisa matla (li-valve tsa mouoane)
• LNG le pipeline ea cryogenic (A350 LF2)
• Lisebelisoa tsa maoatle le maoatle

Ke Hobane'ng ha U re Khetha: Mochine oa rona oa khatiso o koalehileng (ho fihla ho lithane tse 2,500) le lebenkele le kopantseng la mochini oa CNC le re lumella ho fana ka libone tsa li-valve tse felileng ka botlalo, tse itokiselitseng ho kopanya ho tsoa mohloling o le mong. Lits'oants'o tsohle tsa bohlokoa li tsamaisana le litlaleho tsa tlhahlobo ea thepa (MTR / CMTR) le litlaleho tsa tlhahlobo ea maemo. Re amohela tlhahlobo ea motho oa boraro 'me re ka hokahanya tlhahlobo ea lipaki fekthering ea rona.
