Weldable Pressure Vessels thiab Industrial Boilers
Nws yog tus nqi - cov khoom siv tau zoo thiab txhim khu kev qha rau fabricating welded siab hlab ntsha thiab cov boilers muaj kev lag luam uas ua haujlwm nyob rau hauv siab - kub thiab nruab nrab - siab. Nws zoo heev weldability tso cai rau tsim kom muaj siab - weld pob qij txha zoo, thaum nws cov qauv kev ruaj ntseg ua kom ntev - lub sij hawm muaj kev nyab xeeb nyob rau hauv thermal ua tshuab.
Sour Service Ib puag ncig
Lub alloy formulation endows steel phaj nrog zoo tiv thaiv sulfide kev nyuaj siab tawg, ua rau nws haum rau cov khoom siv nyob rau hauv qaub kev pab cuam ib puag ncig uas muaj hydrogen sulfide. Nws tuaj yeem tiv taus kev sib xyaw ua ke ntawm acidic media thiab kub siab, txo qhov kev pheej hmoo ntawm cov cuab yeej tsis ua haujlwm hauv cov roj hnyav thiab roj rho tawm thiab ua cov xwm txheej.
Muaj ntau daim ntawv thov kev lag luam
Tshaj siab tshaj- cov khoom siv coj mus kuaj, nws muaj ntau yam kev siv thoob plaws hauv kev lag luam petrochemical, chemical processing, thiab thermal power industries. Nws yog siv los tsim cov khoom siv hluav taws xob hloov hluav taws xob, cov khoom siv hluav taws xob reactor, thiab siab -cov kav dej kub, hloov mus rau ntau hom kev ua haujlwm uas xav tau kev sib npaug ntawm lub zog thiab kev tiv thaiv corrosion.
Kev siv roj av
Nws yog siv dav hauv kev ua cov pa roj thiab kev sib kis, nrog rau kev tsim cov roj tso tsheb hlau luam, cov khoom siv tswj cov khoom siv siab, thiab cov kav dej rau kev thauj cov roj kub siab - kub. Nws tswj kev ua haujlwm ruaj khov nyob rau hauv cov kev hloov pauv ntawm cov roj siab thiab qhov kub thiab txias, ua kom muaj kev nyab xeeb thiab kev nyab xeeb ntawm cov txheej txheem roj.
