12Cr1MoVG high-pressure boiler yeeb nkab yog cov khoom siv qis-alloy steel yeeb nkab. Nws cov tshuaj muaj pes tsawg leeg muaj cov chromium thiab molybdenum siab, uas ua rau cov yeeb nkab muaj qhov kub thiab txias.
12Cr1MoVg boiler raj yog cov hlau alloy high-pressure boiler raj, uas belongs rau hlau alloy. Nws yog ua raws li cov khoom siv zoo carbon steel thiab tsim nyog ntxiv ib lossis ob peb lub ntsiab lus los txhim kho cov khoom siv kho tshuab, toughness thiab hardenability ntawm cov hlau. Seamless steel kav ua los ntawm cov hlau no yog dav siv hauv hydraulic props, high-pressure gas cylinders, high-pressure boilers, chiv khoom, roj av tawg, tsheb qag bushings, diesel xyaw, hydraulic yeeb fittings thiab lwm yam kav dej.

Kev siv thiab tu ntawm 12Cr1MoVG steel yeeb nkab
1. Kev txhim kho: Thaum lub sij hawm installation, xyuas kom meej qhov flatness thiab verticality ntawm cov yeeb nkab steel kom tsis txhob muaj kev puas tsuaj rau cov yeeb nkab steel.
2. Kev tu: Ntxuav thiab tswj cov kav hlau tsis tu ncua kom tswj tau lawv cov kev huv thiab kev tiv thaiv oxidation. Cov tshuaj ntxuav tshwj xeeb thiab cov tshuaj tiv thaiv tuaj yeem siv los kho.
3. Kev tshuaj xyuas tsis tu ncua: Kev tshuaj xyuas tsis tu ncua ntawm cov kav hlau steel, suav nrog kev tshuaj xyuas qhov muag, kev kuaj tawv tawv, kuaj metallographic, thiab lwm yam.
4. Tiv thaiv kom tsis txhob kub dhau: Thaum lub sijhawm ua haujlwm, qhov kub ntawm cov yeeb nkab steel yuav tsum tau tswj nruj nruj kom tiv thaiv kev puas tsuaj los yog tsis ua hauj lwm ntawm cov yeeb nkab steel los ntawm qhov kub thiab txias.
5. Tiv thaiv corrosion: Rau cov kav hlau uas raug huab cua, kev tiv thaiv corrosion yuav tsum tau ua, xws li txheej txheej nrog cov xim tiv thaiv corrosion, tiv thaiv cov yeeb nkab steel los ntawm corroded.
