Koj puas muab cov fasteners ua raws li NACE MR0175 rau kev pabcuam qaub?
Yog lawm, peb tshwj xeeb hauv kev tsim cov fasteners raws li NACE MR0175 / ISO 15156 rau cov kev pabcuam qaub. Cov fasteners no yog tsim los nrog kev tswj nruj ntawm hardness (feem ntau max HRC 22 rau qee qib) thiab tau txais kev kuaj tshwj xeeb kom ntseeg tau tias muaj kev tiv thaiv sulfide kev nyuaj siab tawg. Cov ntaub ntawv pov thawj kev ua raws cai yog muab rau txhua qhov kev xa khoom xa tuaj rau kev siv roj thiab roj.
Cov Lus Qhia thiab Kev Xaiv Cov Lus Qhia
Xaiv txoj cai alloy steel fasteners yog qhov kev txiav txim siab uas cuam tshuam rau kev nyab xeeb, kev ua neej ntev, thiab kev ua haujlwm ntawm koj qhov project tag nrho.

Raws li peb txav mus txog xyoo 2026, qhov kev thov rau kev txhim khu kev qha, cov kev daws teeb meem siab nrawm txuas ntxiv mus ntxiv. Txawm hais tias koj tab tom tsim ib lub refinery tshiab, sib sau ua ke cov tshuab hnyav, lossis tswj cov txheej txheem tseem ceeb, qhov zoo ntawm koj cov fasteners tsis tuaj yeem cuam tshuam.
Leej twg yuav tsum xaiv peb lub Hoobkas ncaj qha kev daws teeb meem?
- EPC Cov neeg cog lus: Leej twg xav tau bulk ntau nrog guaranteed ntawv pov thawj rau loj-scale industrial tej yaam num.
- OEM Manufacturers: Nrhiav qhov zoo ib yam thiab kev cai specifications rau machinery thiab automotive ntau lawm kab.
- Pab Pawg Saib Xyuas: Yuav tsum tau txhim khu kev qha hloov pauv rau cov tshuab hluav taws xob siab thiab kub kub nrog tsawg kawg nkaus downtime.
Los ntawm kev xaiv cov chaw tsim khoom ncaj qha hauv paus hauv Handan cov cuab yeej cuab tam fastener, koj ruaj ntseg tsis yog tus nqi sib tw nkaus xwb tab sis kuj muaj kev sib koom tes tsim los ntawm ntau tshaj kaum xyoo ntawm kev paub, thev naus laus zis tshiab, thiab kev cog lus tsis tu ncua rau qhov zoo. Peb caw koj los tshuaj xyuas koj qhov project specifications thiab ncav cuag peb pab neeg technical. Cia peb pab koj txheeb xyuas cov qib zoo, txheej txheej, thiab kev teeb tsa kom ntseeg tau tias koj lub rooj sib txoos sawv qhov kev sim ntawm lub sijhawm thiab kev ntxhov siab.
Coj mus rau kauj ruam tom ntej ntawm kev ruaj ntseg koj cov saw hlau nrog hwm, Hoobkas ncaj qha alloy steel fasteners. Tiv tauj peb hnub no rau kev sib tham ntxaws thiab nqe lus raws li koj qhov kev xav tau ntawm qhov project 2026.
