Ubushushu obuphezulu be-alloy yentsimbi yokuphosa iiValve

Phezulu{{0}Ubushushu boBugcisa kwiValufa yentsimbi

 

Isebenza ngokukhethekileyo-kwiqondo eliphezulu lokuphoswa kweevalvu (538℃~1200℃) kumashishini epetroleum, amandla, kunye nesinyithi. Yenziwe kwimigangatho ye-API/ASTM/GB ngobuchwephesha bokuphosa obuchanekileyo.
