Soláthraíonn an post seo tagairt doLaghdaitheoirí brionnaithe 904Lméideanna agus Sleachta reatha.
Sonraíochtaí Laghdaitheora ASME B16.11 904L
Déantar ár laghdaitheoirí 904L (lena n-áirítear Ionsáigh Laghdaigh agus Laghdaitheoirí Snáithithe) a mhonarú trí bhrionnú te beacht chun struchtúr dlúth gránaigh a chinntiú atá in ann seirbhísí ardbhrú a sheasamh.
Caighdeáin: ASME B16.11, MSS SP-79 (le haghaidh ionchuir)
Ábhar Grád: ASTM A182 F904L
Aicmí Brú: 3000 # (Caighdeánach), 6000 #, agus 9000 #
Naisc: Soicéad Táthú (S/W) nó Snáithithe (NPT/BSPT)
Friotaíocht in aghaidh creimeadh: PREN Níos mó ná nó cothrom le 34 (Níos fearr go 316L i dtimpeallachtaí clóiríd)

Praghas Athfhriotail 2026 le haghaidh Laghdaitheoirí Cruach Dhosmálta 904L
Mar gheall ar an ábhar ard nicil (25%) agus moluibdín (4.5%) i 904L, tá an costas in aghaidh an aonaid i bhfad níos airde ná an caighdeán 304 nó 316 grád. Tá praghsanna i margadh na Síne do 2026 cobhsaithe ach tá siad fós íogair do luaineachtaí nicil LME.
Raon Athfhriotail na Síne FOB Reatha (Aicme 3000# - Snáithithe/SW):
NPS 1/2" - 1": $12.50 - $28.00 in aghaidh an aonaid
NPS 1-1/4" - 2": $35.00 - $72.00 in aghaidh an aonaid
NPS 3" - 4": $115.00 - $240.00 in aghaidh an aonaid
Fachtóirí a bhfuil Tionchar acu ar an Athfhriotail Deiridh:
Méid an Ordaithe: Cáilíonn mórorduithe (os cionn 100 aonad) le haghaidh lascaine 5-10%.
Deimhniú: Áiríonn praghsanna MTRanna caighdeánacha (Tuarascálacha Tástála Muilte) go EN 10204 3.1. Tá cigireacht tríú páirtí (TPI) ag SGS nó BV ar fáil ar chostas breise.
Críochnaigh: Tá picilte caighdeánach agus pasivation san áireamh; tabhóidh anáil gheal nó -snasta leictrilít préimh.
Roghnú laghdaitheoir Cruach brionnaithe 904L
Sonraítear laghdaitheoirí 904L le haghaidh tiúchan seirbhíse aigéad sulfarach idir 10-98% agus teochtaí suas le 40 céim, i gcás ina dteipfeadh ar chaighdeán 316L. Mar gheall ar uimhir choibhéiseach friotaíochta pitting an chóimhiotail (PREN) de 34-37 tá sé oiriúnach do thimpeallachtaí clóiríd suas le 1,000 ppm.
Cinntíonn comhlíonadh tríthoiseach ASME B16.9 feistiú ceart-suas le comhpháirteanna píopa cúplála, agus lamháltais á gcoimeád laistigh de ±1.5mm do thoisí deiridh{-go{{{{{{{}}}deireadh). Soláthraíonn monaróirí Síneacha a chloíonn le córais cháilíochta ISO 9001:2015 cruinneas comhsheasmhach tríthoiseach atá ríthábhachtach do nósanna imeachta táthúcháin.
Trí chóireáil teasa ag 1,100-1,150 céim agus múchadh tapa ina dhiaidh sin, uasmhéadaítear friotaíocht creimeadh agus airíonna meicniúla. Coscann anáil réiteach cuí íogrú agus coinníonn sé friotaíocht an chóimhiotail ar chreimeadh idirghráinneach.
Achoimre
Ba cheart do cheannaitheoirí laghdaitheora cruach dhosmálta 904L an cóimheas laghdaithe sonrach agus an rang brú a sholáthar, toisc go mbíonn tionchar suntasach ag tiús bhalla ar mheáchan ábhartha agus ar phraghas deiridh. Mar phríomh-mhonaróir atá bunaithe sa tSín, coinnímid fardal láidir amhábhar AL6XN agus 904L chun amanna luaidhe de 15-20 lá a chinntiú le haghaidh gaibhneachta saincheaptha.
