12Cr2Mo High Pressure Seamless Boiler Yeeb Nkab

Cov12Cr2Mo Seamless Boiler Tubeyog sib npaug rau ASTM A335 P22 Boiler Pipes thiab ASTM A213 T22 Tubes. GB/T9948 12Cr2Mo steel tubing yog hom pearlite kub-resistant steel. Nws muaj kev tiv thaiv zoo heev rau hydrogen corrosion, high-temperature mechanical zog, thiab kub creep kuj. Cov tubing no tau siv dav rau kev siv roj av tawg.

12Cr2Mo alloy steel kav yog tsuas yog siv los tsim cov khoom zoo carbon steel, alloy structural steel thiab stainless tshav kub-resistant steel seamless steel kav rau chav boiler kav dej siab thiab siab dua, raws li zoo raws li cov kav dej rau roj tawg.

12Cr2Mo seamless alloy boiler hlab yog tsuas yog siv rau chav yeeb nkab phab ntsa thiab headers nrog superheater yeeb nkab nto kub tsawg dua los yog sib npaug rau 580 degree thiab cov yeeb nkab saum npoo kub tsawg dua los yog sib npaug li 540 degree rau high-power power station boilers xws li 300 thiab 600MW.
