Cov qhab nia xaiv tau
- Alloy 625 (Nickel Alloy): Tus hwm npib tsib xee-raws li alloy muab kev tiv thaiv zoo heev rau cov cua sov thiab tshuaj corrosion. Nws yog qhov kim dua tab sis zoo tagnrho rau qhov chaw huab cua hauv kev siv tshuaj lom neeg thiab aerospace.
- 316L Stainless hlau (Austenitic Stainless hlau): Feem ntau siv stainless hlau nrog zoo corrosion kuj nyob rau hauv nruab nrab ib puag ncig. Nws tsis muaj lub zog thiab qhov chaw tiv thaiv corrosion ntawm S32750, ua rau nws tsuas yog tsim nyog rau qis dua - daim ntawv thov kev pheej hmoo.
- Titanium Qib 2 thiab 5: Titanium muab kev tiv thaiv corrosion zoo heev thiab lub zog siab - rau - qhov hnyav piv. Qib 2 paub txog kev tiv thaiv dej hiav txwv thiab bio-kev sib raug zoo, thaum Qib 5 muaj zog dua txhua yam. Cov no yog cov kev xaiv zoo heev uas txo qhov hnyav thiab qhov siab tshaj plaws corrosion kuj tseem ceeb heev.
Cov chaw siv
2507 Super Duplex tubing yog tsim los siv rau hauv qhov chaw hnyav hauv qhov chaw sov uas muaj cov tshuaj chloride siab, siab salinity, thiab nruab nrab - txog - kub. Nws yog siv nyob rau hauv ib tug ntau yam ntawm geothermal piping daim ntaub ntawv, nrog rau cov dej thauj thiab subsurface installation, xws li:
Geothermal brine kis kab, reinjection pipelines nyob rau hauv geothermal systems, geothermal cua sov system piping, tshav kub exchanger thiab cog txheej txheem piping, ncaj qha - faus underground kab, trench - nteg pipelines, thiab lub ntsiab trunk kab rau hauv av - qhov chaw tshav kub twj tso kua mis. Lub raj boasts lub neej kev pab cuam tsawg kawg yog 30 xyoo thiab ntev tshaj plaws - lub sij hawm ua hauj lwm kub ntawm 280 degree, yog li ua tau raws li tag nrho cov kev cai ntawm feem ntau ntawm nruab nrab - mus rau - siab - kub nyob rau hauv tej yaam num.

FAQ
Q: Cov yeeb nkab no puas tuaj yeem siv rau hauv cov dej hauv av uas muaj cov ntsiab lus chloride ion siab?
A: Yog. Nws cov pitting kuj sib npaug (PREN) Ntau dua lossis sib npaug li 40 tuaj yeem tiv taus pitting thiab kev ntxhov siab corrosion tawg hauv cov dej hauv av nrog cov tshuaj chloride ion txog li 50,000 ppm, ua rau nws haum rau qhov siab tshaj -mineralization geothermal ib puag ncig.
Q: Yuav ua li cas tiv thaiv corrosion ntawm cov yeeb nkab faus rau hauv av?
A: Cov txheej txheem kev kho mob yog acid pickling thiab passivation (AP), uas txhim kho corrosion kuj. Rau cov av hnyav heev corrosion ib puag ncig, tshwj xeeb los tiv thaiv - cov coatings xws li epoxy resin thiab polyethylene muaj. Nws tseem pom zoo kom siv cov insulating gaskets cais cov yeeb nkab los ntawm cov yeeb nkab carbon steel kom tsis txhob galvanic corrosion.
Q: Puas yog S32750 ua tau raws li cov qauv kev pabcuam rau cov kua qaub hauv kev lag luam roj thiab roj?
A: Yog. Nws ua tau raws li qhov yuav tsum tau ua ntawm NACE MR0175 / ISO 15156 thiab tsim nyog siv rau hauv cov tshuab hluav taws xob hauv ntiaj teb uas muaj H₂S thiab CO₂.
