Los ntawm kev kho mob khaub thuas- kos duab, sab hauv phab ntsa roughness (Ra) ntawm no loj txoj kab uas hla welded stainless hlau yeeb nkab yog txo kom tsawg dua los yog sib npaug rau 1.6 μm; Qhov no ua rau cov kua dej tsis muaj zog thiab ua rau cov yeeb nkab muaj zog tiv taus scaling thiab clogging.
Cov khoom siv piping nthuav tawm tshwj xeeb tsis kam rau kev xeb thiab intergranular corrosion. Tom qab vuam, tag nrho ntev ntawm cov yeeb nkab tau txais kev kho mob, ua rau cov nplej ua kom zoo nyob rau hauv ob qho tib si weld seam thiab tshav kub- thaj tsam cuam tshuam. Tsis tas li ntawd, cov khoom siv tau ua tiav dhau qhov kev ntsuam xyuas kev sib xyaw ua ke raws li ASTM A262 Practice E (los yog txoj kev sulfuric acid-copper sulfate).

Cov qhab nia xaiv tau
- Rau ultra-siab-kub siv-xws li cov uas pom nyob rau hauv refinery siab-kub cua sov rauv thiab tso pa systems-Qib 310S yog qhov kev xaiv, muaj peev xwm ua hauj lwm ruaj khov ntawm kub tshaj 1000℃.
- Rau cov kav dej tsis tu ncua raug rau qhov ntsuas kub ntawm 400℃txog 800℃-thiab rau qhov kev tshaj tawm tag nrho-weld kev kho cua sov tsis muaj peev xwm ua tau- Qib 321 thiab 347/347H tau pom zoo rau lawv cov kev tiv thaiv zoo heev rau intergranular corrosion.
- Rau cov koom haum refinery piping tes hauj lwm nrog cov peev nyiaj tsawg thiab tsis tshua muaj corrosive mob, Duplex Stainless Steel Qib 2205 yog qhov kev xaiv tsim nyog; thaum nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion tawg, nws tsis haum rau ultra-siab- daim ntawv thov kub.

FAQ
Q: Dab tsi yog qhov siab tshaj plaws sab nrauv thiab phab ntsa tuab koj tuaj yeem tsim tau?
A: Peb tuaj yeem tsim cov kab uas hla mus txog 1800mm thiab phab ntsa thicknesses txog 60mm. Thov paub meej nrog peb lub tuam txhab kev ua haujlwm ua ntej rau kev ntxiv - loj loj.
Q: Puas yog tag nrho cov kav dej puas tau ua tsis tau -kev kuaj ua ntej xa khoom?
A: Yog. Tag nrho cov kav dej ASTM A358 tau dhau los ntawm ob qho tib si ultrasonic (UT) thiab radiographic (RT) tsis yog- kuaj kev puas tsuaj ua ntej tawm hauv lub Hoobkas, nruj me ntsis ua raws li cov qauv 1-Class 5. Lawv tsis muaj qhov tsis xws luag xws li weld porosity, tawg, thiab slag suav nrog. Ua tiav cov ntawv xeem muaj nyob thiab ua tau raws li cov qauv kev lees paub ntawm lub tshuab ua kom zoo.
Q: Koj puas tuaj yeem ua tau siab -kub tsis kam thiab corrosion- tiv thaiv kev kho mob ntxiv?
A: Txhawb. Peb tuaj yeem muab cov kev kho mob tshwj xeeb xws li electropolishing, ntxiv dag zog rau passivation, siab -tej txheej kub, thiab kev ntxhov siab- nyem annealing, txhim kho cov kav dej tsis kam mus rau siab - kub oxidation thiab media corrosion.
