ASTM A312 UNS S30815 253MA Pepa Fa'amatalaga Fa'atekinisi Paipa Uila

Folasaga

O leASTM A312 UNS S30815 253MA Paipa Uameao se u'amea u'amea u'amea austenitic maualuga e iloa ona o lona tete'e maualuga i le fa'ama'iina o le vevela, pala, ma mea fa'ainisinia sili ona lelei i si'osi'omaga vevela maualuga.253MAua mamanuina faapitoa mo le tautua i talosaga e manaʻomia ai le mautu o le vevela maualuga, aemaise lava ile ogaumu ma fale vevela. O lona tete'e mata'ina i scaling, carburization, ma oxidation lautele ua avea ai ma mea faatuatuaina mo siosiomaga ogaoga.

O lenei vasega o le u'amea u'amea e fa'aaogaina lautele i mea tau alamanuia maualuga ma e lelei mo fa'aoga e matua taua uma ai le malosi ma le fa'ama'iina.

Meatotino Meatotino: Uiga Autu

253MA(UNS S30815) tu'ufa'atasia lelei le malosi o le vevela ma le fa'ama'i fa'ama'i. O le mea lea e lelei ai mo faʻaoga i siʻosiʻomaga ogaoga, e pei o ogaumu ma faʻafefe vevela. O mea o loʻo i ai le maualuga o le chromium ma le nickel content, e maua ai le teteʻe lelei i le faʻamaʻiina i le vevela e oʻo atu i le 1150 ° C (2100 ° F).

Gaosiga Fa'agasologa: Tufuga mo le Sa'o

Le gaosiga o253MA uamea uamea paipamulimuli i faiga fou gaosiga e faʻamautinoa ai le maualuga ma le tumau:

  1. Gaosi Paipa Seamless: Fausia e ala i le extrusion, tatui rotary, ma faiga elongation e fausia ai paipa seamless ma mafiafia puipui tutusa.
  2. Fa'agasologa Galulue Malili: O ata maalili po'o fa'agasologa o femalaga'iga e fa'aaogaina e maua ai fua sa'o ma luga lamolemole.
  3. Togafitiga vevela: O paipa e faia togafitiga vevela ile vevela faʻapitoa e faʻaleleia ai a latou mea faʻainisinia ma faʻatinoga maualuga-vevela.
  4. Pickling & Pasivation: O paipa e pikiina e aveese fua ma oxide ata tifaga ma pasivated ina ia mautinoa le tetee atu i le pala.

Su'ega ma Asiasiga: Fa'amautinoaga Tulaga

E mulimulitaia e le Womic Steel se fa'ata'ita'iga fa'apitoa e fa'amautinoa ai le tulaga maualuga mo253MA uamea uamea paipa:

  • Su'esu'ega o Fa'ainumera: Fa'amaonia ile fa'aogaina ole spectroscopic techniques e fa'amaonia ai o lo'o fa'amalieina le fa'aogaina o mea fa'apitoa.
  • Su'ega Fa'ainisinia: Su'ega tensile, ma'a'a, ma a'afiaga e fa'amaonia ai le fa'atinoga o meafaitino ile vevela eseese.
  • Su'ega Hydrostatic: O paipa e fa'ata'ita'iina mo le malosi o le mamafa e fa'amautinoa ai le fa'atinoina o le sa'olotoga.
  • Su'ega Le Fa'aleagaina (NDT): E aofia ai su'ega ultrasonic, eddy current, ma le vali e su'e ai so'o se fa'aletonu i totonu po'o luga.
  • Su'esu'ega Va'ai & Itulau: O paipa ta'itasi e va'aia va'aia mo le fa'auma o luga, ma siaki le sa'o o fua fa'atatau.
