321 Titanium Stabilized Valve Castings

Igoa Oloa: 321 Ti-Tu'u Valve Uamea Fa'amautu
(Shandong Hongyang Uamea Fa'apitoa - Maualuluga-Foma'i Fofo Fofo o le A'au)

Sa'o - lafo mai le ZG10Cr18Ni9Ti (321 Stainless Steel) fa'atasi ai ma le fa'amautu o le titanium, o tatou vaega valve ua fa'ainisinia mo le maualuga-vevela vevela. Lelei mo siosiomaga acidic / oxidative e oo atu i le 650 tikeri ma intergranular corrosion tulaga lamatia, tuuina atu 2-3x umi auaunaga ola nai lo tulaga 304 valves.

1. Puipuiga a'afia Intergranular

Ti fa'amautu: Ti e sili atu pe tutusa ma le 5×C mea i totonu e fa'ate'aina le fa'alogoina (ASTM A262 Practice E fa'amaonia)

Malosi maualuga-vevela: Fa'atumauina Sili atu pe tutusa ma le 150MPa malosi maua i le 600 tikeri

Tete'e fa'ama'i:<0.2mm/year scale thickness at 900°C

2. Tekonolosi Tu'u Sa'o

Ala lavelave o tafega: Monobloc cast body/bonnet e aveese ai vaivaiga uelo

Fa'atonuga: Fa'apalepale CT6 (ISO 8062) i luga o fa'amaufa'ailoga taua

Tulaga lelei: E pei o-tu'u Ra E itiiti ifo pe tutusa i le 12.5μm, fa'amae'aina i le Ra1.6μm

3. Fa'atino -Ato'a

Feso'ota'iga ala o fa'asalalauga: Tete'e i vaila'au fefiloi ( Itiiti pe tutusa ile 40% H₂SO₄/HNO₃)

Fa'ailoga o le mamafa: Vasega 150-2500 (ASME B16.34 fa'amalieina)

Cryogenic malosi: Sili atu pe tutusa ile 80J aafiaga ile -196 tikeri (LNG-fa'amaonia)

Talosaga masani

Fa'amamaina: FCC iunite vevela (650 tikeri / kasa oona)

La'au vaila'au: Va'au fa'atonu o le nitric acid (40% HNO₃ @90 tikeri)

LNG Fale: Cryogenic globe valve (-162 tikeri auaunaga)

Faiga faaniukilia: Valau fa'atonutonu a le boric acid (tete'e -radiation)

✔ Puleaina o le fa'aputuga: I -su'esu'ega fa'apitoa o le vevela + fa'amaoniga fua faatatau o le Ti/C
✔ NDT: 100% PT i tino + 20% RT sampling
✔ Su'ega fa'atinoga: Fa'ata'ita'iga tulaga fa'agaioia P-T uila

• API 600/API 6D • ASME B16.34 • NACE MR0175
• EN 10204 3.1 tusipasi • PED 2014/68/EU

Fa'alautelega e fai faitalia:

X-a'a ua asiasia (ASTM E186 fa'asino)

Cryogenic aafiaga su'ega lipoti

3D su'esu'e lipoti vaega

Lagolago Inisinia

• Ta'iala filifilia mea mo ala fa'asalalau fa'apitoa
• CFD-fa'ata'ita'iga ala fa'asolo o lo'o avanoa
• Atina'e fa'ata'ita'iga i totonu ole 20 aso faigaluega

O lenei fa'amatalaga fa'atekinisi e maua ai fa'amatalaga au'ili'ili mo su'esu'ega fa'ainisinia a'o fa'atumauina le taula'i atu i fa'amatalaga fa'apitoa ma agava'a fa'atino. Ua aveese uma fa'amatalaga fa'afeso'ota'i pe a mana'omia.
