Cov cuab yeej siv tshuaj thiab cov kav dej cia siab ntau ntawm cov hlau tsis huv, muab cov khoom siv tsis zoo, corrosion-resistant tsim nyog hauv kev tsim khoom thiab cua sov.ua kom tsis muaj menyuam.Txawm li cas los xij, cov thermoplastics muaj uas tuaj yeem muab cov khoom zoo dua qub lossis cov nqi qis dua.Cov yas tsis tshua muaj nqi xws li polypropylene (PP) thiab polyvinyl chloride (PVC) tuaj yeem siv tau rau cov tshuab tsis-compendial.Lwm tus, xws li polyvinylidene fluoride (PVDF) muab kev tiv thaiv tshav kub ntau dua, tuaj yeem tsim nyog rau cov dej tsis txaus, txawm hais tias lawv xav tau kev txhawb nqa tas mus li hauv cov ntawv thov kub.Tus nqi ntawm PVDF qhov system yuav yog kwv yees li 10-15 feem pua qis dua tus nqi ntawm cov hlau tsis muaj steel ib zaug muaj xws li passivation, boroscope radiographic tshuaj xyuas, thiab lwm yam.Cov txheej txheem tshiab ntawm kev koom nrog PVDF tubing tawm ntawm qhov vuam ntau dua li ua tau nrog cov hlau tsis muaj steel.Thaum kub dua, txawm li cas los xij, thermal expansion ntawm cov yas ua ib qho kev txhawj xeeb loj.
Kev xaiv cov khoom siv yuav tsum ua kom zoo ib yam (tag nrho 316L lossis tag nrho 304L thiab lwm yam) thoob plaws hauv kev faib khoom, khaws cia, thiab ua cov txheej txheem yog tias tau npaj ua ntu zus.
Rau cov dej tsis txaus, kev siv 316L steel yog nyiam.Rwb thaiv tsev raustainless hlau kavYuav tsum tsis muaj chlorides, thiab cov hangers muab nrog cov khoom sib cais los tiv thaiv galvanic corrosion.
304L thiab 316L stainless hlau yog qhov kev lag luam nyiam nyob rau hauv cov tso tsheb hlau luam rau kev khaws cia cov dej tsis txaus.Jacket khoom nyob rau hauv kev sib cuag nrog lub plhaub yuav tsum tau sib xws, kom tsis txhob chromium depletion nyob rau hauv lub weld-cuam tshuam aav.Cov dej tsis-compendial yuav tsis xav tau tib theem ntawm kev tiv thaiv corrosion los yog siv cov pa roj carbon tsawg-nickel-chromium alloys thiab tshwj xeeb tiav, nyob ntawm tus tswv.'s dej specifications.
