34Cr4 Alloy Seamless Steel Pipe Features

1. Malosi maualuga, sili ona lelei le ofuina ma le malosi.

2. Machinability lelei ma faʻatinoga mautu i lalo o le avega maualuga ma tulaga faʻalavelave maualuga.

Talosaga Field

34Cr4 alloy seamless paipa uʻamea o loʻo faʻaaogaina lautele i le fale gaosi oloa, masini inisinia, masini faufale ma isi fanua.

Fa'amatalaga Togafitiga vevela

Tiini 860ºC, suau'u mālūlū;Fa'avevela 500ºC, fa'alili vai, fa'amalulu suau'u.

Tulaga Fa'atau

Tuuina atu i le vevela (faʻasaʻoina, faʻafefeteina poʻo le vevela maualuga) poʻo le leai o se faʻamaʻi vevela, o le tulaga o le tuʻuina atu e tatau ona faʻaalia i totonu o le konekarate.
