Kev sib txuas hom thiab xaus
Xaus:Feem ntauTE (Threaded thiab Coupled).
Kev sib txuas:Vim hais tias C110 yog siv nyob rau hauv siab - siab qaub qhov dej,Kev sib txuas hwm hwm(xws li, VAM TOP, Tenaris Blue, Fox) tau pom zoo. Cov no muab "Metal-rau-Metal" cov ntsaws ruaj ruaj uas muaj roj- nruj, uas muaj kev nyab xeeb dua rau H2S kev pabcuam tshaj li tus qauv API threads.
Couplings:Yuav tsum tau ua los ntawm seamless C110 qib Tshuag thiab yuav tsum tau ua tib yam kev kho cua sov thiab SSC kuaj raws li cov yeeb nkab lub cev.
Kev xeem rau API 5CT C110
Vim tias muaj kev phom sij ntawm qhov chaw qaub, C110 kev sim yog ib qho nyuaj tshaj plaws hauv API tus qauv:
Kev Ntsuas SSC (Sulfide Stress Cracking):
Txheem:Raws li NACE TM0177.
Yuav tsum tau:Txoj Kev A (Tensile) lossis Method D (DCB) yuav tsum tau ua pov thawj tias cov khoom tsis tawg hauv
H2SH2S
saturated brine.
Hardness Test (yuav tsum tau):
Tseem ceeb:Txhua qhov sib koom ua ke thiab kev sib txuas yuav tsum tau sim hardness. Hla -sectional hardness traverses yuav tsum tau ua kom tsis muaj "hard spots" tshaj30 HRC.
Metallographic Examination:
Kev txheeb xyuas ntawm microstructure, feem ntau xav tau qhov tsawg kawg ntawm 90% tempered martensite kom ntseeg tau tias muaj kev sib haum xeeb.
NDT (Tsis yog -Kev kuaj kev puas tsuaj):
100% Ultrasonic Testing (UT) thiab Magnetic Particle Inspection (MPI) txhawm rau txheeb xyuas qhov tsis zoo ntawm sab hauv thiab saum npoo.
Hydrostatic Test:
Txhua qhov sib koom ua ke raug sim ntawm kev kub siab kom ntseeg tau tias cov pa tawm - pov thawj kev ncaj ncees.
Charpy V-Ntch Impact Test:
Xyuas kom cov khoom tseem tawv thiab ductile ntawm qhov kub thiab txias kom tsis txhob nkig tawg.
