Sucker Qws Rau Suav Factories
C-class high-zoo carbon steel pas nrig yog tsim los ntawm SSYD-1 (sib npaug rau AISI1526), nrog rau nruab nrab lub zog, zoo yas, theem tiv thaiv corrosion thiab lwm yam tshwj xeeb rau ib puag ncig ntawm acidic nruab nrab tsis ua rau sulfide kev nyuaj siab tawg.Qib D sucker yog ua los ntawm high-Cr-Mo alloy structural steel 30CrMoA (sib npaug rau AISI 4130), muaj zog siab, zoo plasticity, lub neej ntev thiab lwm yam ntxwv, muaj feem xyuam rau cov tsis-corrosive los yog me ntsis corrosive ib puag ncig ntawm qhov tob tob.Qib K nqus cov pas nrig yog ua los ntawm qib high-qib Ni-Mo alloy structural steel 20Ni2MoA (sib npaug rau AISI 4620), muaj zog nruab nrab, zoo ductility, corrosion kuj thiab lwm yam ntxwv, haum rau siv nyob rau hauv lub teeb loads thiab qhov dej ntiav nyob rau hauv lub xub ntiag. ntawm corrosive media.
Raws li API tus qauv tsim, cov pas dej da dej yog ua los ntawm cov khoom siv zoo carbon steel lossis hlau alloy.Ob qhov kawg muaj tib cov xov sab nraud.Raws li tus qauv qib, nws tau muab faib ua 1 thiab 2, uas tuaj yeem txuas nrog lub siab kawg ntawm tus pas nrig zoo, lossis qis kawg ntawm cov roj zoo nqus pas nrig thiab.
