Dab tsi yog qhov siab - tus qauv yuav tsum muaj rau cov khoom hauv kev lag luam roj thiab roj?

Qhov siab - tus qauv yuav tsum tau ua rau cov khoom siv hauv kev lag luam roj thiab roj yog feem ntau cuam tshuam rau plaub yam: cov khoom siv corrosion, kev ntseeg tau ntawm cov qauv, kev hloov pauv ib puag ncig, thiab kev tsim cov precision, los xyuas kom meej ntev - lub sijhawm ua haujlwm nyab xeeb nyob rau hauv huab cua xws li kev kub siab, kub kub, thiab corrosion siab.

Khoom siv Corrosion Resistance thiab Crack Resistance Requirements
Nyob rau hauv ib puag ncig hnyav uas muaj hydrogen sulfide (H₂S), carbon dioxide (CO₂), thiab chloride ions (Cl⁻), cov ntaub ntawv yuav tsum muaj kev tiv thaiv sulfide kev nyuaj siab tawg (SSC) thiab pitting corrosion:

• Cov pa roj carbon steel thiab qis- alloy steel: Yuav tsum ua raws li GB / T 20972.2-2025 tus qauv, uas qhia meej txog cov kev cai rau kev tawg- cov pa roj carbon steel thiab cov hlau tsis tshua muaj hlau, suav nrog kev tswj hardness, cov txheej txheem kho cua sov, thiab cov txheej txheem kuaj xyuas.
• Corrosion-resistant alloys (CRAs): Xws li npib tsib xee-raws li alloys thiab duplex stainless hlau, yuav tsum ua kom tau raws li kev faib tawm thiab kev ntsuam xyuas ntawm GB/T 20972.3-2025 lossis tus qauv thoob ntiaj teb ISO 15156, xaiv cov khoom tsim nyog raws li qhov tsis xws li H₂S ib nrab siab, kub, thiab p.
• Kev kho saum npoo: Cov khoom tseem ceeb xws li piston rods feem ntau siv chrome plating (0.03-0.05mm) lossis ceramic txheej los txhim kho corrosion kuj. Kev kub ceev laser cladding ntawm martensitic stainless hlau tau raug saws los ua lwm txoj hauv kev electroplating hauv qee kis.

Cov qauv kev ntseeg siab thiab kev ruaj ntseg tsim yuav tsum muaj

Cov Cheebtsam yuav tsum tau soj ntsuam RAMS nruj me ntsis (Kev ntseeg tau, Muaj, Kev Tswj Xyuas, Kev Nyab Xeeb) kom ruaj khov ua haujlwm thoob plaws hauv lawv lub neej tag nrho:

RAMS cov txheej txheem kev ntsuam xyuas kom meej meej txhais cov txheej txheem -qib kev tshuaj ntsuam rau cov khoom siv xws li cov ntoo tsim hauv qab hiav txwv, FPSO modules, thiab subsea li qub, npog cov qauv tsis ua haujlwm, cov tswv yim tu, thiab kev tswj hwm kev pheej hmoo. Cov chaw tiv thaiv kev nyab xeeb xav tau kev tshuaj xyuas tsis tu ncua, xyuas kom tsis muaj qhov txawv txav hauv cov khoom sib kis, tsis muaj lub tswb nrov hauv lub tshuab hluav taws xob, thiab cov ntaub ntawv saib xyuas kev ruaj ntseg. Ib qho kev npaj kaw thiab kev saib xyuas yuav tsum tau tsim.

3D cov khoom luam tawm tau muab tso rau hauv API 20S tshiab (hlau) thiab API 20T (polymer) cov qauv, kev tsim cov txheej txheem tsim khoom ntxiv, cov kev xav tau, thiab kev taug qab los xyuas kom meej tias cov txheej txheem tshiab ua tau raws li cov ntaub ntawv pov thawj nruj ntawm kev lag luam roj thiab roj.

Ib puag ncig huab cua Adaptability Requirements heev

Cov xwm txheej sib txawv yuav tsum muaj cov lus teb tshwj xeeb rau kev sib koom ua ke xws li kub, av noo, vibration, thiab ntsev tsuag:

• Qhov kub thiab txias: Pneumatic Cheebtsam tuaj yeem ua haujlwm ntawm -40℃txog 150 degree. Silicone roj hmab ntsaws ruaj ruaj yog siv los tiv thaiv jamming ntawm qhov kub thiab txias, thaum fluororubber yog siv los tiv thaiv kev laus nyob rau hauv high-temperature ib puag ncig.
• Ntsev Txau Corrosion Tiv Thaiv: Lub cev lub cev yog galvanized / electrophoretically kho nrog nitrile roj hmab foob, ua tiav qhov ntsuas dej tsis zoo IP65; stainless hlau (304/316) yog tsim rau chemical thiab electroplating Rhiav, nrog lub neej ntev tshaj 5000 teev.
• Kev vibration thiab kev poob siab: Lub tshuab cuab yeej pneumatic tuaj yeem tiv thaiv kev vibrations ntawm 10–55 Hz (amplitude Tsawg dua lossis sib npaug li 1 hli), thiab kev ua haujlwm tsis zoo raug tiv thaiv los ntawm kev tiv thaiv -loosing qauv thiab tsis tsim qauv.
• Kev ntsuas huab cua ib puag ncig: suav nrog kev caij tsheb kauj vab siab thiab qis qis, ntub dej kub, thiab kev ntsuas tsis tshua muaj siab los xyuas qhov ruaj khov ntawm cov khoom siv hluav taws xob hauv tsheb thiab kev sib txuas lus hauv cov xwm txheej huab cua.
