ASTM A179 / ASME SA179 Tubu eziwanyisiganya ebbugumu - BLOG

Okwanjula

ASTM A179 / ASME SA179 enyonyola ttanka ezitaliiko buzibu, ezikubiddwa ennyogovu-ezikubiddwa, ezitono-kaboni ezikoleddwa yinginiya okusobola okutambuza obulungi ebbugumu n’okukola obulungi mu kukola. Nga tulina okuzimba bbugwe okutono-n’okufuga okukakali okw’ebyuma, ttanka zino zikozesebwa nnyo mu biwanyisiganya ebbugumu n’ebifuumuula mu makolero gonna agalongoosa, eddagala ly’amafuta, n’amasannyalaze.Octal Pipe egaba ttanka za A179/SA179 eri abakola EPC n’ebyuma mu nsi yonna, nga bawagira ttanka zombi ez’obwereere n’enkuŋŋaana za U-bend.

Ebirungo by’Eddagala

Kemiko ya kaboni entono eyongera ku kukola mu nnyonta ku U-okubeebalama n’okugaziwa kwa tube-okutuuka ku-tubesheet.

Ekintu	Ekyetaagisa (wt%) .	Obukulu bwa Yinginiya
Kaboni (C) .	0.06–0.18	Akuuma ductility okusobola okukola
Manganese (Mn) .	0.27–0.63	Okunyweza n’okuggya omukka mu mubiri
Ekirungo kya Phosphorus (P) .	Entono oba yenkana 0.035	Ekoma ku buzibu bw’okumenya
Ekibiriiti (S) .	Entono oba yenkana 0.035	Okwoza kungulu okw’omunda n’okuweta

Ebintu by’Ebyuma

Eby'obwa nannyini	Ekyetaagisa Ekitono ennyo	Omulimu mu Bawanyisiganya Ebbugumu
Amaanyi g’okusika	Okusinga oba okwenkana 325 MPa (47 ksi) .	Omusingi gw’obukuumi bw’ebizimbe
Amaanyi g’amakungula	Okusinga oba okwenkana 180 MPa (26 ksi) .	Afuga okukyukakyuka mu kiseera ky’okukola
Okuwanvuwa	Okusinga oba okwenkana ebitundu 35% .	Kikulu nnyo okusobola okugaziya mu ngeri ey’obukuumi
Obukaluba	Entono oba yenkana 72 HRB	Eziyiza okwatika mu kiseera kya U-okubeebalama

Ebintu bino bisobozesa okukola mu ngeri ey’obukuumi n’okuweereza okunywevu mu bundles za exchanger.

Okukola & Okulongoosa mu bbugumu

ASTM A179 / ASME SA179 tubes zikolebwa nga ziyita mu nkola y’emirimu efugibwa etaliimu buzibu bw’okukola nga egobererwa okukuba ebifaananyi mu ngeri ennyogovu okusobola okutuuka ku kugumiikiriza okw’ebipimo okunywevu n’ebitundu eby’omunda ebiseeneekerevu okusobola okulongoosa mu bulungibwansi bw’okutambuza ebbugumu-.

Enkola y’okufulumya etaliiko buzibu

Hollow billet → okufumita → okukola mu bbugumu → multi-pass cold drawing

Okufuga ebipimo kukakasa nti ekyetaagisa ekitono-ekisenge kituukirira mu butuufu

Okukuba ebifaananyi mu nnyonta kwongera ku kumaliriza kungulu n’obuyonjo obw’omunda-kikulu nnyo okukendeeza ku bucaafu mu bifo ebiwanyisiganya ebbugumu

Okulongoosa mu bbugumu okusembayo

Oluvannyuma lw’okuyita okusembayo okunnyogoga-okusika, ttanka zikolebwako ebbugumu kuOkusinga oba okwenkana 1200℃F ( Okusinga oba okwenkana 650℃) .ku:

Okumalawo situleesi ezisigaddewo ezireetebwa emirimu egy’ennyogoga
Okuzzaawo ductility eyeetaagisa kuU-okubeebalama n'okugaziya kwa tubesheet
Okulongoosa obutebenkevu bw’enzimba obw’ekiseera ekiwanvu- wansi w’emigugu egy’ebbugumu egy’enzirukanya

Embeera y'okungulu & okuteekateeka

Ebiweereddwaminzaani-ey'obwereereokukuuma omulimu gw’ebbugumu ogusinga obulungi
Enkomerero ziriokuyonja era burr-free, okukakasa okwesigika weldability oba okugaziwa ebyuma mu kiseera ky’okukuŋŋaanya
Okufuga kuno okw’okukola n’ebyuma kuyamba okukakasa obulamu obuwanvu obw’okuweereza, okwesigamizibwa kw’enzimba, n’okuteekebwa mu ngeri ey’obukuumi mu bundles za high-density exchanger.

Okukebera & Okugezesa

Okusinziira ku ASTM A179 ne ASTM A450/A450M:

Ekintu eky’okukebera	Omugaso
Okukebera amazzi oba NDE	Leak-okukakasa okunyweza
Okugezesa okupapajjo	Okukebera amaloboozi n’obugumu
Flaring / Okugezesebwa mu kifo	Akakasa obusobozi bw’okugaziya tubesheet
Okugezesebwa kw’obukaluba	Okukakasa omutendera gw'omulimu ogw'ennyogovu-
Okulondoola obubonero & MTC	Awagira okwekenneenya QA n’okubala pulojekiti

Engineering & Okugula Ebintu Ebikulu

Olubu	Obulagirizi bwa Yinginiya	By’olina Okulambika
Sayizi ya Tube	OD mm 3.2–76.2 (1/8–3 mu) .	OD × Obugumu bwa bbugwe obutono × Obuwanvu
Okusobola okukola (formability).	Esaanira U-okubeebalama n'okugaziya	Min. radius y’okubeebalama Esinga oba eyenkana 2–2.5 × OD
Embeera y’okungulu	Okufuga obucaafu & okukola obulungi mu bbugumu	Scale-free nga erina enkomerero ezikuumibwa
Omutendera gw’okukebera	Okusinziira ku nkola criticality	Ebigezo bya Hydrostatic/NDE + ductility
Ebiwandiiko	Audit & okugoberera code	MTC nga erina okulondoola okujjuvu
Okupakinga n'okutambuza ebintu	Ziyiza okukulukuta n’okukosebwa	Okukuuma ebweru w'eggwanga mu nnyanja-grade

Ekitundu kimu nga kiwagira byombiokukubaneokugula ebintuokusalawo.

Okusaba

Ebiwanyisiganya ebbugumu ebya Shell & tube
Amaanyi-ebifo ebifuumuuka
Eggaali y’omukka enyogoza ebyuma ebirongoosa
Ebintu ebinyogoza empewo mu makolero n’ebinyogoza empewo
Enkola z’okugaana ebbugumu
Ku byuma ebirimu chloride- oba okukwatibwa amazzi g’ennyanja:
lowooza ku kukkiriza okukulukuta, okusiiga, oba aloy ezirongooseddwa nga ASTM A213.

Okubumbako

ASTM A179 / ASME SA179 seamless heat exchanger tubes ziwa ebbugumu ekirungi ennyo-transfer efficiency, obusobozi obwesigika okukola, n'omulimu ogukakasibwa mu makolero cooling units.

Octal Pipe egaba ttanka za A179/SA179 ezilondoolebwa mu bujjuvu nga zirina U-bend fabrication ey’okwesalirawo, ebiwandiiko bya MTC ebijjuvu, n’okukeberebwa kwa BV / ABS okujuliziddwa, okukakasa nti okugoberera pulojekiti za exchanger ezisaba.
