Pup Joint
Ib tug pup sib koom ua ke yog ib lub casing los yog tubing ntawm qhov ntev luv dua li Range 1 nrog tib txoj hlua txuas, siv los kho qhov ntev ntawm cov hlua tubular rau nws qhov kev xav tau.
Pup Joints yog tsim los ntawm AISI 4145H lossis 4140H-hloov hlau alloy, kho cua sov rau Brinell Hardness ntau ntawm 285-341 nrog Charpy "V" notch yam tsawg kawg nkaus lub zog ntawm 40 ft / lb ntawm 70 ° F thiab ib nti hauv qab ntawm qhov chaw. .Pup Joints yog kho cua sov rau 110,000 PSI yam tsawg kawg nkaus.Tag nrho cov kev sib txuas yog phosphate coated los tiv thaiv galling thaum pib ua-up.
Lawv muaj nyob rau hauv tus qauv ntev ntawm 5', 10', 15' thiab 20' nrog rau lwm yam kev teeb tsa raws li kev thov.
Integral Pup Joints mob siab rau Sour Service daim ntawv thov muaj.PJ-110 PUP S yog Sour Service Pup Joint siv ASCOWELL C cov ntaub ntawv muab kev txhim kho kev tiv thaiv rau Sulfide Stress Cracking nrog siab yield zog.
Peb tuaj yeem muab ntau yam khoom siv laum hlua thiab cov khoom siv nrog tus qauv API lossis kev ua haujlwm siab
kev sib txuas kom tau raws li qhov xav tau tshaj plaws ntawm kev xav tau drilling.

Kev tiv thaiv corrosion ntawm roj av casing feem ntau muab faib ua peb hom:
- Txhuam cov tshuaj tiv thaiv corrosive rau ntawm phab ntsa sab nrauv.
- Txhuam los tiv thaiv corrosion txheej rau ntawm phab ntsa sab hauv.
- Txhuam cov tshuaj tiv thaiv corrosive thiab txias txheej.
Nrog kev siv cov roj casings thiab pup sib koom ua ke nyob rau hauv hnyav roj extraction industries xws li cov polar thiab marine.Nws yuav tsum muaj cov khoom siv thiab cov qauv ntawm cov roj av pup sib koom ua ke, thiab nws yuav tsum muaj qhov zoo nodality, zoo heev lub cev muaj zog, ruaj khov khoom, thiab ntau yam kub hloov.Yog tias cov roj casing tsis tuaj yeem ua tau, nws yuav tsum tau coated nrog cov tshuaj tiv thaiv corrosive los pab nws tiv taus qhov hnyav.Cov txheej txheem ntawm cov phab ntsa sab nrauv yog siv los txo cov kev xeb sab nraud, thiab cov txheej txheem tiv thaiv corrosion ntawm cov phab ntsa sab hauv yog los txo kev sib txhuam, txo cov corrosion hauv cov yeeb nkab, thiab nce cov roj thauj.Anti-corrosive rwb thaiv tsev txheej yog siv los thauj cov roj crude thiab roj roj, thiab txo cov cua sov tawm ntawm cov raj xa mus rau hauv av.
Sab nrauv yuav tsum tau coated (xim) thiab cim raws li API 5CT tus qauv, bundled nrog ntoo rooj plaub, pallets, steel siv los yog lwm yam ntim raws li cov neeg muas zaub xav tau.
