Chinyorwa ichi chinopa imwe nzira yekumisikidzwa kune yeAustralia chikafu indasitiri masevhisi.Zvakadai zvinosanganisira:
ASTM A269 "Kutsanangurwa kweGeneral Seamless uye Welded Austenitic Stainless Simbi Pipe"
ASTM A249 "Kutsanangurwa kweWelded Austenitic Steel Boiler, Superheater, Heat Exchanger, uye Condenser Tubes"
AS1528 yakadzokororwa muna 2001 nevemakambani makuru muAustralian food production and tubing industry.AS 1528 yakasiyana nekuti inovhara zvese zvine chekuita nekuiswa kunze kwemachubhu.
Saizi yese magiredhi akajairwa akadai semagiredhi 304, 304L, 316 uye 316L.AS1528.1 anovhara ese magiredhi e duplex uye austenitic Stainless steels akanyorwa muASTM A240.
Saizi yese inoda fusion welded zvigadzirwa zvisina filler simbi.Makakatanwa akadai seASTM A270, ASTM A269 uye AS 1528 zvakare inovhara zvigadzirwa zvisina musono.
AS 1528 inotsanangura ukobvu hwezita hwe 1.6mm kune ese kunze kwemadhayamita (OD) asi 2 mm ye203.2 mm OD;humwe hukobvu hunogona kutaurwa nemutengi.Kushivirira kwakajairwa ndiko +nil, -0.10mm.Kushivirira kwakashata zvachose itsika yakajairika yemhando dzose dzepombi, uye inogadzirwa kumucheto kwepasi kweiyo tolerance range.A typical range is between 1.52 and 1.58 mm.Kushivirira uku kunoshandawo kune pombi fittings.
* ASTM A554 Kushivirira kwemamiriro ekubvisa weld.*AS1528 inovharawo OD saizi 12.7, 19.0, 31.8, 127.0, 152.4 uye 203.2mm
Zvose izvi pombi nokurondedzerwa zvinopa rusvingo ukobvu uye kunze dhayamita limits.The mukati dhayamita haritauri zvakasiyana.
Iwo akasiyana epamusoro pekupedzisira zvivakwa anokurudzirwa neChikafu Indasitiri Services Australia ndeaya anotevera:
Zvigadzirwa zvekurapa zvinoshandiswa muindasitiri yechikafu zvinoda mapaipi asina weld zvakasara mukati memukati.
Iwo emakanika zvimiro zveakasiyana simbi isina simbi mamakisi anowanzo shandiswa muindasitiri yechikafu ndeaya anotevera:
