ASTM A179 / ASME SA179 Tubes ya échangeur ya chaleur - BLOG

Maloba ya ebandeli

ASTM A179 / ASME SA179 elimboli ba tubes sans soudure, froid-bendami, basse-acier carbone ingénierie mpo na transfert ya chaleur efficace mpe performance ya formation ya kozala na confiance. Na botongi ya mur ya moke-mpe na contrôle métallurgique ya makasi, ba tubes oyo esalelamaka mingi na ba échangeurs ya chaleur mpe ba condensateurs na kati ya ba industries ya raffinerie, pétrochimie, mpe ya puissance.Octal Pipe epesaka ba tubes A179/SA179 pona ba fabricants ya EPC na ba équipements mondiaux, oyo esimbaka ba tubes ya pamba mpe ba assemblages ya U-bend.

Composition chimique oyo esalemi

Chimie ya carbone ya nse-ematisaka mosala ya malili mpo na U-bending mpe tube-na-tubesheet expansion.

Eloko	Esengeli (poids%) .	Signification ya Ingénierie
Carbone (C) 1.1.	0.06–0.18	Ebatelaka ductilité mpo na kosala
Manganese (Mn) ya .	0.27–0.63	Kolendisama mpe ko désoxyder
Phosphore (P) ya .	Na nse to ekokani na 0,035	Ezali kopekisa kobukana ya kobukana
Soufre (S) ya .	Na nse to ekokani na 0,035	Bopeto ya surface ya kati mpe soudable

Propriétés mécaniques

Lopango	Esengeli ya moke koleka	Role na ba échangeurs ya chaleur
Bokasi ya kokangama	Monene koleka to ekokani na 325 MPa (47 ksi) .	Marge ya sécurité structurelle
Bokasi ya Rendement	Monene koleka to ekokani na 180 MPa (26 ksi) .	Contrôlaka déformation na tango ya formation
Elongation ya nzoto	Monene koleka to ekokani na 35% .	Critique mpo na expansion ya sécurité
Bokasi ya makasi	Na nse to ekokani na 72 HRB	Epekisaka kopasuka na tango ya kogumbama ya U-

Ba propriétés oyo epesaka nzela na fabrication sûr mpe service stable na ba faisceaux ya échangeur.

Fabrication & Traitement ya molunge

Ba tubes ASTM A179 / ASME SA179 esalemaka na nzela ya flux ya mosala ya fabrication sans soudure contrôlée oyo elandi na dessin froid ya précision mpo na kozua ba tolérances dimensionnelles serrées mpe ba surfaces internes lisses mpo na amélioration ya efficacité ya transfert ya chaleur-.

Processus ya production sans soudure

Billet creux → ko percer → formation ya moto → multi-passe dessin ya malili

Contrôle dimensionnel e assurer que besoin minimum-mur ekokisama na bosikisiki

Dessin ya malili ematisaka bosilisi ya likolo mpe bopeto ya kati-ezali na ntina mingi mpo na kokitisa bosoto na ba échangeurs ya chaleur

Traitement ya chaleur ya suka

Sima ya passe ya suka ya malili-draw, ba tubes ezo traité na chaleur naMonene koleka to ekokani na 1200 degrés F ( Monene to ekokani na 650 degrés ) .na:

Bolongola ba stress oyo etikali oyo eyaka na mosala ya malili
Zongisa ductilité oyo esengeli mpo naU-kogumbama mpe bopanzani ya nkasa ya tube
Kobongisa stabilité structurelle ya tango molayi-na se ya ba charges thermiques cycliques

Condition ya surface & préparation ya likolo

Ezali kopesamaéchelle-ya ofelempo na kobatela performance thermique ya malamu
Nsuka ezalipeto mpe burr-ofele, ko assurer soudure fiable to expansion mécanique na tango ya assemblage
Contrôle oyo ya fabrication mpe métallurgique esalisaka mpo na ko assurer vie ya service ya molayi, fidélité structurelle, mpe installation ya sécurité na ba faisceaux ya échangeur ya haute-densité.

Botali & Bomeki

Na boyokani na ASTM A179 mpe ASTM A450/A450M:

Eloko ya botali	Mokano
Momekano ya hydrostatique to ya NDE	Fuite-vérification ya serrage
Momekano ya kopɛtola	Vérification ya son mpe ductilité
Momekano ya flaring / Substitut	Validate capacité ya expansion ya feuille ya tube
Momekano ya makasi	Malili-kondimisa ya nivo ya mosala
Marquage & traçabilité ya MTC	Esungaka ba revues ya QA na ba audits ya projet
