ASTM A795 YEEB yog cov yeeb nkab roj teeb tshwj xeeb siv rau cov tshuaj tiv thaiv hluav taws, nrog kev tsim tawm tshwj xeeb thiab cov txheej txheem yuav tsum tau ua. Nws cov yam ntxwv tseem ceeb thiab kev siv yog raws li hauv qab no:
1. Cov yam ntxwv tseem ceeb
Kev Tsim Tsim Tsim
Cov ntsiab lus muaj roj carbon qis (0.15% -0.35%), noj rau hauv tus account todness thiab lub zog yuav tsum tau ua.
High sulfur thiab phosphorus tswj (Sulphor tswj (Sulphur
Alloy cov ntsiab xws li chromium, npib tsib xee, thiab molybdenum tuaj yeem ntxiv los txhim kho corrosion tsis kam.
Dual txheej txheem raug
Txhawb ob qho txheej txheem vuam (cov txheej txheem mainstream) thiab cov txheej txheem seamless kom yoog raws li cov xwm txheej sib txawv.
Cov txheej txheem saum npoo tsheb kub-dip galvanizing kev kho mob (Zinc txheej ntau dua lossis sib npaug rau 85μm) txhim kho corrosion tsis kam.
Cov Khoom Siv Neeg Kho Tshuab
Tos lub zog ntau dua los yog sib luag rau 180MPA, Tensile lub zog ntau dua lossis sib luag rau 325mpa, ntsib lub siab xav tau ntawm cov hluav taws tiv thaiv kab ke.
2. Cov chaw thov tseem ceeb
Pipelines
Lub tsev tua hluav taws sprinkler system pob tw / ceg pipelines;
Hluav Taws Hydrant Dej Pipelines thiab Kev Siv Dej Kub Ceev.
Tshwj xeeb scenario expansion
Ib puag ncig qhov kub tsawg hluav taws xob pipelines (xws li -46℃ua haujlwm);
Tshuaj lom neeg cov khoom siv cov kav dej paus tso cov kav dej (Customized Alloy Raffived version yuav tsum tau).

3. Kev Ua Haujlwm thiab Siv Cov Ntsiab Lus
Cov Txheeb Xyuas Zoo
Kuaj cov tuab (ntau dua los yog sib npaug rau 85μm) thiab kev sib dhos ntawm galvanized txheej;
Yuav tsum kuaj cov weld zoo (vuam txheej txheem yeeb nkab) thiab flattening / devended kev ua haujlwm.
Hloov chaw txwv tsis pub
Kev kub siab rau cov raj (xws li sa178) lossis siab siab txheej txheem kev teeb tsa (xws li A500) tsis tuaj yeem hloov.
