ASME SA179 waa halbeeg loogu talagalay tuubooyinka birta ah ee aan kala go 'lahayn ee loogu talagalay isweydaarsiga kulaylka oo ay samaysay Bulshada Injineerada Farsamada ee Mareykanka (ASME), kaas oo qeexaya tilmaamayaasha muhiimka ah sida habka wax soo saarka, halabuurka kiimikada, sifooyinka farsamada iyo dulqaadka cabbirka ee tuubada. Heerkani wuxuu hubinayaa in tuubada birta ahi ay leedahay iska caabin cadaadis oo aad u fiican, hab-dhaqanka kulaylka iyo iska caabinta daxalka ee kala duwan ee is-weydaarsiga kulaylka, wuxuuna ku habboon yahay xaaladaha shaqada ee adag ee kiimikada, korontada, cuntada iyo warshadaha kale.
Faa'iidooyinka ugu muhiimsan ee habka sawir-qaadista qabow
Tuubada caadiga ah ee qabowga laga soo saaro ee Maraykanka waxay isticmaashaa tiknoolajiyada sawir-qaadista heerkulka qolka waxaana si sax ah u sameeyay caaryada. Waxay leedahay sifooyinka soo socda:
Cabbirka saxda ah: dulqaad adag oo dhexroorka dibadda ah (sida ±0.10mm), dhumuc darbiga oo isku mid ah, oo ku habboon qaab-dhismeedka isweydaarsiga kulaylka ee shaabadaysan.
Xoojinta sifooyinka farsamada: isbeddelka qabowgu wuxuu ka dhigayaa miraha inay u jeedaan jihada, waxay hagaajisaa xoogga jiidista (≥325MPa) iyo adkaanta, iyadoo la ilaalinayo adkeysiga wanaagsan.
Tayada dusha sare ee aadka u fiican: darbiga gudaha oo siman (qallafsanaan Ra≤0.8μm), waxay yareysaa iska caabbinta dareeraha, waxayna wanaajisaa hufnaanta is-weydaarsiga kulaylka.
Tilmaamaha cabbirka muhiimka ah
ASME SA179 waxay daboolaysaa noocyo kala duwan oo qeexitaanno ah si loo daboolo baahiyaha xaaladaha kala duwan ee is-weydaarsiga kulaylka:
Kala duwanaanshaha dhexroorka dibadda (mm) Kala duwanaanshaha dhumucda derbiga (mm) Xaaladaha caadiga ah ee codsiga
12.7~25.4 1.24~2.11 Beddelaha kulaylka saxanka ee is haysta
25.4~38.1 2.11~3.81 Qalabka isku beddelka kulaylka ee qolofta kiimikada iyo tuubada
38.1~50.8 3.81~5.59 Kondenserka cadaadiska sare leh ee saldhigga korontada
Kiisaska codsiga warshadaha
1. Warshadaha kiimikada
Sifeynta batroolka: Xirmooyinka tuubooyinka is-weydaarsiga kulaylka ee loo isticmaalo fal-galayaasha haydarojiinaynta, oo u adkaysta daxalka haydarojiin sulfide (fiirsashada H₂S ≤50ppm).
Soo saarista aashitada sulfuric: Qaboojinta gaaska SO₂ ee heerkulka sare leh (≤450℃), dahaarka ka hortagga daxalka ayaa loo baahan yahay marka la isticmaalayo birta kaarboonka.
2. Koronto
Tuubooyinka Kondensarka: Warshadaha korontada ku shaqeeya ee kuleylka, tuubooyinka birta ah ee SA179 waxay u adkaystaan ​​​​cadaadiska uumiga 0.1MPa, iyadoo uumigu uu yahay 50W/(m·K), iyo kor u kaca waxtarka kondensarka 15%.
