ASTM A179 / ASME SA179 Heat Exchanger Tubes - BLOG

Mawu Oyamba

ASTM A179 / ASME SA179 imatanthauzira machubu opanda msoko, ozizira-okokedwa, otsika-a carbon steel opangidwa kuti azitengera kutentha kwabwino komanso kupanga kodalirika. Pokhala ndi zochepera-zomanga khoma ndi kuwongolera mwamphamvu zitsulo, machubuwa amagwiritsidwa ntchito kwambiri posinthanitsa kutentha ndi ma condenser m'mafakitale onse oyeretsera, petrochemical, ndi magetsi.Octal Pipe imapereka machubu a A179/SA179 a EPC yapadziko lonse lapansi ndi opanga zida, zothandizira machubu opanda kanthu ndi ma U{0}}ma bend assemblies.

Chemical Composition

Low{{0}carbon chemistry imapangitsa kuzizira kogwira ntchito kwa U-kupindika ndi chubu-ku-kukulitsa tubesheet.

Chinthu	Zofunikira (wt%)	Kufunika kwa Engineering
Mpweya (C)	0.06–0.18	Amasunga ductility kupanga
Manganese (Mn)	0.27–0.63	Kulimbikitsa ndi deoxidation
Phosphorous (P)	Ochepera kapena ofanana ndi 0.035	Malire brittleness
Sulfure (S)	Ochepera kapena ofanana ndi 0.035	Kuyeretsa mkati ndi kutenthetsa

Mechanical Properties

Katundu	Zochepa Zofunika	Udindo mu Zosintha Zotentha
Kulimba kwamakokedwe	Kuposa kapena kufanana ndi 325 MPa (47 ksi)	Mphepete mwachitetezo chachitetezo
Zokolola Mphamvu	Kuposa kapena kufanana ndi 180 MPa (26 ksi)	Amawongolera ma deformation panthawi yopanga
Elongation	Kuposa kapena kufanana ndi 35%	Zofunikira pakukulitsa kotetezeka
Kuuma	Ochepera kapena ofanana ndi 72 HRB	Imaletsa kung'amba pa U-kupindika

Zinthu izi zimathandizira kupanga zotetezeka komanso ntchito zokhazikika m'magulu osinthanitsa.

Kupanga & Chithandizo cha Kutentha

Machubu a ASTM A179 / ASME SA179 amapangidwa kudzera m'mayendedwe oyendetsedwa bwino opangidwa motsatiridwa ndi kujambula kozizira bwino kuti azitha kupirira bwino komanso malo osalala amkati kuti azitentha bwino{2}}kutumiza mwachangu.

Kupanga kosasinthika

Hollow billet → kuboola → kupanga kutentha → zambiri-zojambula zozizira kwambiri

Dimensional control imawonetsetsa kuti -zofunika pakhoma zikukwaniritsidwa molondola

Kujambula kozizira kumawonjezera kutha kwa pamwamba komanso ukhondo wamkati-zofunika kwambiri kuti muchepetse kuipitsidwa ndi zotenthetsera

Chithandizo chomaliza cha kutentha

Pambuyo pozizira komaliza-machubu amathiridwa ndi kutenthaKuposa kapena kufanana ndi 1200 digiri F (Wamkulu kuposa kapena wofanana ndi 650 digiri)ku:

Chepetsani kupsinjika kotsalira komwe kumachitika chifukwa cha ntchito yozizira
Bwezerani ductility zofunika kwaU-kupindika ndi kukulitsa machubu
Limbikitsani kukhazikika-kwanthawi yayitali potengera kuchuluka kwa ma cyclic thermal

Maonekedwe apamwamba & kukonzekera

Zaperekedwasike-yaulerekukhalabe ndi magwiridwe antchito abwino kwambiri amafuta
Mapeto ndiwoyera ndi-mwaulere, kuonetsetsa kuti weldability odalirika kapena kukulitsa makina pa msonkhano
Kupanga ndi kuwongolera zitsulo kumeneku kumathandizira kuti pakhale moyo wautali wantchito, kudalirika kwa kapangidwe kake, ndi kuyikika kotetezeka m'mapaketi apamwamba kwambiri-osinthanitsa.

Kuyang'ana & Kuyesa

Mogwirizana ndi ASTM A179 ndi ASTM A450/A450M:

Ntchito Yoyendera	Cholinga
Kuyesedwa kwa Hydrostatic kapena NDE	Kutsikitsitsa-kutsimikizira kulimba
Mayeso osalala	Kuwunika kwabwino komanso ductility
Flaring / M'malo mayeso	Imatsimikizira kuthekera kokulitsa ma tubesheet
Mayeso olimba	Chitsimikizo chozizira- cha mlingo wa ntchito
Marking & MTC traceability	Imathandizira kuwunika kwa QA ndi kuwunika kwa polojekiti

Zofunika Zauinjiniya ndi Kugula

Gulu	Upangiri Waumisiri	Zoyenera Kutchula
Kukula kwa Tube	OD 3.2–76.2 mm (1/8–3 mu)	OD × Kuchepa kwa Khoma × Utali
Formability	Zoyenera U-kupindika ndi kukulitsa	Min. utali wopindika Wokulirapo kapena wofanana ndi 2–2.5 × OD
Surface Condition	Kuwongolera koyipa & magwiridwe antchito amafuta	Osachepera-ndi mfundo zotetezedwa
Mulingo Woyendera	Kutengera kutsutsa kwadongosolo	Mayeso a Hydrostatic/NDE + ductility
Zolemba	Audit & code kutsata	MTC yokhala ndi traceability yonse
Packaging & Logistics	Pewani dzimbiri ndi zotsatira zake	Chitetezo cha m'madzi-kutumiza kunja

Gawo limodzi lothandizira onse awirikupangandikugulazisankho.

Chidule

Machubu a ASTM A179 / ASME SA179 otenthetsera opanda msoko amapereka kutentha kwabwino-kutumiza mwachangu, kupanga kodalirika, komanso magwiridwe antchito otsimikizika pamayunitsi oziziritsa a mafakitale.

Octal Pipe imapereka machubu olondola a A179/SA179 okhala ndi U-njira zopindika, zolemba za MTC, ndi BV / ABS zoyendera, kuwonetsetsa kutsatiridwa kwama projekiti osinthana nawo.
