Paipa U'amea ASTM A671 CC65 CL 12 EFW: Paipa Fa'apipi'i Malosi Maualuga mo Galuega Fa'apisinisi

Paipa ASTM A671 CC65 CL 12 EFWo se paipa EFW maualuga le tulaga lelei e faʻaaogaina lautele i paipa suauʻu, kesi, vailaʻau, ma faiga faʻapisinisi lautele. O nei paipa e ausia manaʻoga oTulaga faatonuina ASTM A671ma ua mamanuina mo felauaiga o vai i le mamafa feololo ma le mamafa maualuga ma faʻaoga fausaga. E ofoina atu le faigofie ona faʻapipiʻi ma meatotino faʻainisinia, ma avea ai ma mea lelei mo inisinia paipa faʻapisinisi.

Fa'amatalaga o Meafaitino

O paipa e gaosia mai le uʻamea maualalou'amea malosi CC65, o le tuufaatasiga o vailaʻau e matuā pulea lelei ina ia maua ai le faigofie ona faʻapipiʻi, teteʻe atu i le 'ele ma le gafatia i le vevela maualuga. O le uʻamea e iai lona fausaga tutusa o le fatu ma faʻamalieina ai manaʻoga maualuluga o le fausaga ma le mamafa e faʻaaogaina i pisinisi.

Fa'atulagaga Fa'akemikolo

Fa'atulagaga Fa'akemikolo (Taua Masani)
Elemene Kaponi (C) Manganese (Mn) Silikoni (Si) Sulfur (S) Fosforo (P) Nickel (Ni) Kromium (Cr) Kopa (Cu)
Anotusi (%) 0.12–0.20 0.50–1.00 0.10–0.35 ≤0.035 ≤0.035 ≤0.25 ≤0.25 ≤0.25

Manatua: O le tuufaatasiga moni o vailaʻau e ono fesuisuiaʻi teisi i vaega taʻitasi ae e masani ona ausia tulaga faatonuina o le ASTM A671 CC65 CL 12.

Meatotino Fa'amekanika

Meatotino Taua
Malosiaga o le Fetaia'i 415–550 MPa
Malosiaga o le Tuuina Atu ≥280 MPa
Fa'aloloa ≥25%
Malosi o le A'afiaga E maua suega a'afiaga o le vevela maualalo e tusa ai ma tulaga masani, filifiliga

Talosaga

E masani ona faʻaaogaina paipa uʻamea ASTM A671 CC65 CL 12 EFW i:

  • Paipa suau'u ma kesi
  • Paipa fa'agasologa o vaila'au
  • Faiga felauaiga vai e maualuga le mamafa
  • O paipa fa'apisinisi ma masini fesuia'i vevela
  • Lagolago fausaga ma vaega fa'amekanika

Afifiina ma Felauaiga

Puipuiga: Ua fa'amaufa'ailogaina pito o paipa, ua fa'asu'u i totonu ma fafo e tete'e atu ai i le 'ele, ua afifiina i pepa po'o se ata palasitika e tete'e atu ai i le 'ele

Fa'aputuga: Fa'amauina i fusi u'amea i ni fusi; lagolago laupapa po'o paleti e maua pe a talosagaina

Felauaiga: Talafeagai mo felauaiga mamao e ala i le sami, nofoaafi, poʻo le auala
