I. Txheej txheem cej luam
Nrog rau txoj kev loj hlob sai ntawm thoob ntiaj teb tshuaj thiab lub zog logistics, stainless hlau cia tank thiab ntim tau dav siv nyob rau hauv kev thauj mus los thiab cia cov tshuaj, khoom noj khoom haus thiab dej haus, lub zog thiab lwm yam ntaub ntawv. Vim nws zoo heev uas tsis muaj kub toughness thiab zoo corrosion kuj, austenitic stainless hlau yog dav siv nyob rau hauv kev tsim kho ntawm cryogenic cia tso tsheb hlau luam, khoom siv thiab loj cryogenic lug.

3.Our electrode GES-308LT (E308L-16)
Txhawm rau ua kom tau raws li kev xav tau ntawm kev lag luam, peb lub tuam txhab tau tsim ntau yam ntawm qhov kub thiab txias, siab toughness austenitic stainless hlau electrodes, cov tshuaj muaj pes tsawg leeg ntawm cov hlau deposited (raws li qhia nyob rau hauv Table 1) thiab ruaj khov mechanical zog (raws li qhia nyob rau hauv lub rooj. 2), thiab muaj tag nrho cov txheej txheem vuam zoo heev Kev ua tau zoo, thiab zoo heev kub tsis tshua muaj kev cuam tshuam toughness, qhov cuam tshuam ntawm nws cov nyiaj ferrite ntawm qhov cuam tshuam tus nqi (Table 3).

1. Tsawg tam sim no vuam yuav tsum tau siv;
2. Khaws lub arc kom tsawg li sai tau;
3. Thaum lub arc viav vias mus rau ob sab ntawm qhov zawj, nres ib pliag, thiab lub viav vias dav yog tswj tsis pub dhau 3 npaug ntawm txoj kab uas hla ntawm electrode.
5.Pipeline daim duab ntawm vuam consumables daim ntawv thov
Rau -196 ℃ qis-kub tsis zoo stainless hlau vuam consumables, tom qab xyoo ntawm kev tshawb fawb thiab kev loj hlob ntawm vuam consumables, peb twb muaj kev txhawb welding consumables rau vuam rods, khoom cores, flux cores thiab submerged arcs, thiab tau tsim tes electrode nruam arc. welding consumables rau tag nrho-txoj hauj lwm vuam, thiab muaj ntau yam engineering daim ntawv thov ua tiav, txais tos cov neeg muas zaub los sab laj thiab xaiv!
