SB111 C44300 khoom yog dab tsi?

ASTM B111 C44300 tooj liab tubing yog dab tsi?

ASTM B111 C44300 naval tooj dag tubing tau ntev tau siv nyob rau hauv tshav kub exchangers thiab condensers vim nws zoo heev corrosion kuj thiab superior tshav kub hloov zog. Nthuav 44300 naval tooj dag yog siv rau hauv cov dej tsis qab, dej brackish, thiab seawater daim ntaub ntawv, nrog rau cov roj thiab roj systems, vim hais tias ntawm nws ua ke zoo ntawm corrosion kuj, high tshav kub hloov efficiency, thiab cov nqi khoom qis dua.

Tej kev siv

Marine Engineering: Seawater condensers, nkoj propellers, evaporators, thiab cov kav dej sib pauv cua sov.

Cov Khoom Siv Hluav Taws Xob: Cov khoom siv hluav taws xob siab - cov cua kub sib txawv, cov condensers, thiab cov kav dej rau corrosive kua hauv thermal fais fab nroj tsuag.

Cov Cheebtsam muaj: li qub, lub cev twj tso kua mis, sib sib zog nqus - kos qhov chaw (xws li rivets thiab txiv ntseej), thiab cov khoom siv hluav taws xob.
