SAE4340 40CrNiMoA Alloy Seamless Steel Paipu

SAE4340 40CrNiMoA Alloy Seamless Steel Pipe Kiʻi ʻia

ʻO ka wehewehe pōkole:

40CrNiMoA paipu kila maʻemaʻe ʻole he kiʻekiʻe-ikaika, kiʻekiʻe-toughness alloy structural paipu kila.ʻO ka mea nui i loko o ka chromium, nickel, molybdenum a me kahi mea liʻiliʻi o ka carbon, silicon, manganese a me nā mea ʻē aʻe, ma o nā ʻāpana kikoʻī a me nā kaʻina hana wela, he kūpaʻa maikaʻi ka corrosion a me ka hana wela kiʻekiʻe.Ma muli o kona ʻano mechanical maikaʻi loa a me ka laulā o nā kahua noi, ua hoʻohana nui ʻia i nā ʻoihana he nui.

Kahua noi

1. I loko o ka ʻoihana petrochemical, hiki ke hoʻohana ʻia e hana i nā lako kī e like me nā moku kiʻekiʻe, nā reactors, nā mea hoʻololi wela, a me nā mea ʻē aʻe, hiki ke kū i nā hopena o ka wela kiʻekiʻe, ke kaomi kiʻekiʻe a me ka media corrosive.

2. I loko o ka ʻoihana uila, hiki ke hoʻohana ʻia e hana i nā ʻāpana no nā set generator, boilers, turbines a me nā mea hana ʻē aʻe, hiki ke kū i ka ukana kiʻekiʻe a me nā kūlana hana kiʻekiʻe.

3. Ma ke kahua mokulele, hiki ke hoʻohana ʻia e hana i nā ʻāpana koʻikoʻi e like me ka pae hoʻokele mokulele a me nā hale fuselage e hoʻomaikaʻi ai i ka palekana a me ka hana o ka mokulele.

Eia hou, hiki ke hoʻohanaʻia nā paipu kila 40CrNiMoA no ka hanaʻana i nā mea nui i nā kaʻa, nā moku, nā ala kaʻa a me nāʻoihana'ē aʻe e hoʻonui i ka maikaʻi o ka huahana a me ka hilinaʻi.
