SAE4340 40CrNiMoA Alloy Fa'a'umea U'amea

SAE4340 40CrNiMoA Alloy Seamless Steel Paipa Faaalia Ata

Fa'amatalaga Puupuu:

40CrNiMoA u'amea seamless paipa u'amea o se maualuga-malosi, maualuga-maa'a tu'uaga paipa uamea fausaga.O lona tuufaatasiga e masani lava ona aofia ai le chromium, nickel, molybdenum ma sina vaega itiiti o carbon, silicon, manganese ma isi elemene, e ala i vaega patino ma togafitiga vevela, o loʻo i ai le malosi o le corrosion ma le maualuga o le vevela.Ona o lona tulaga lelei faʻainisinia ma le tele o ituaiga o faʻaoga fanua, ua faʻaaogaina lautele i le tele o alamanuia.

Talosaga Field

1. I totonu o le gaosiga o le petrochemical, e mafai ona faʻaaogaina e gaosia ai meafaigaluega autu e pei o vaʻa maualuga, reactors, faʻafefe vevela, ma isi, e mafai ona tatalia aʻafiaga o le vevela maualuga, maualuga maualuga ma faʻasalalauga faʻasalalau.

2. I totonu o le eletise eletise eletise, e mafai ona faʻaaogaina e gaosia ai vaega mo seti afi, faʻavela, uila afi ma isi meafaigaluega, lea e mafai ona tatalia le maualuga o le avega ma le maualuga o le vevela o galuega.

3. I totonu o le malae vaalele, e mafai ona faʻaaogaina e gaosia ai vaega autu e pei o le faʻaleleia o vaalele ma fausaga faʻapipiʻi e faʻaleleia ai le saogalemu ma le faʻatinoga o vaalele.

E le gata i lea, e mafai foi ona faʻaogaina paipa uʻamea 40CrNiMoA e gaosia ai vaega autu i totonu o taavale, vaʻa, nofoaafi ma isi pisinisi e faʻaleleia atili ai le lelei ma le faʻamaoni.
