Chitoliro cha Chitsulo cha ASTM A335 42CRMO

Chitoliro cha Chitsulo cha Alloy chimagwiritsidwa ntchito pazinthu zomwe zimafunikira kukana kwa dzimbiri kolimba komanso kukhazikika bwino komanso pamtengo wachuma. Kunena mwachidule, mapaipi a alloy amakondedwa m'malo omwe mapaipi achitsulo amatha kulephera. Pali magulu awiri azitsulo za alloy - high alloys ndi low alloy steels. Mapaipi omwe amapanga zitsulo zotsika za alloy ali ndi alloying zomwe zimakhala pansi pa 5%. Pamene alloying zili mkulu aloyi zitsulo zingakhale pakati 5% kuti pafupifupi 50%. Zofanana ndi ma aloyi ambiri mphamvu yogwira ntchito ya Chitoliro Chopanda Seamless Pipe ndi pafupifupi 20% kuposa chitoliro chowotcherera. Chifukwa chake m'mapulogalamu omwe ali ndi mphamvu yayikulu yogwirira ntchito ngati chofunikira, kugwiritsa ntchito chitoliro chopanda msoko ndikoyenera. Ngakhale kuti ndi amphamvu kuposa chitoliro chowotcherera, mtengo wake ndi wokwera kwambiri. Komanso, chiopsezo intergranular dzimbiri pa kutentha anakhudzidwa weld zone kwambiri mu mankhwala welded. Kusiyana kowoneka pakati pa Chitoliro Chowotcherera Chitsulo cha Aloyi ndi chinthu chopanda msoko ndi msoko wa latitudinal kutalika kwa chitoliro. Komabe, lero, ndi kupita patsogolo kwaukadaulo, msoko womwe ukupezeka pa Alloy Steel ERW Pipe utha kuchepetsedwa kwambiri pogwiritsa ntchito mankhwala apamtunda, kotero kuti umakhalabe wosawoneka ndi maso a anthu.
