Hordhac ASTM A519

ASTM A519Tuubooyinka waa in lagu sameeyaa habka aan kala go 'lahayn waana in lagu sameeyaa kuleyl ama qabow sida ku cad.

Tuubooyinka wareegsan ee dhexroorkoodu aanu ka badnayn 12 3/4 inji (325 mm).

Tuubooyinka birta ah waxaa sidoo kale lagu samayn karaa qaab afargeesle ah, qaab leydi ah, ama qaabab kale sida loogu baahdo.

ASTM A519 -2023: Qeexitaanka Heerka Caadiga ah ee Tuubada Farsamada ee Kaarboon iyo Birta Daawaha ah ee aan kala go 'lahayn

Nooca Tuubada

ASTM A519 waxaa loo kala saari karaa iyadoo loo eegayo maaddada birta:Bir Kaarboon ahiyo Birta Daawaha.

Bir kaarboon ahwaxaa loo qaybiyaaKaarboon Yar(Tuubada Farsamada),Bir Kaarboon Sare lehiyoLa baabi'iyay ama la dib u fosfooreeyay, ama labadabaBir Kaarboon ah, si loogu waafajiyo baahiyaha warshadaha ee kala duwan iyo xaaladaha codsiga.

Marka aan la cayimin darajada, soosaarayaashu waxay leeyihiin ikhtiyaarka ah inay bixiyaanMT1015 ama MTX1020darajooyin.

Cabbirka Kala Duwan

Dhexroorka dibadda: 13.7 - 325 mm;

Dhumucda derbiga: 2-100mm.

Alaabta Ceeriin

Birta waxaa lagu samayn karaa hab kasta.

Habka Wax Soo Saarka

Tuubooyinka waxaa samayn doona ageeddi-socod aan kala go 'lahaynwaana in lagu dhammeeyaa kuleyl ama qabow, sida ku cad.

Tuubooyinka birta ah ee aan tolnayn waa tuubooyin aan lahayn tolmo la isku tolay oo dhan.

Tuubooyinka qabow-dhammaadaywaxaa lagula talinayaa baahiyaha sare ee saxnaanta cabbirka iyo tayada dusha sare.

Walaaca ugu weyn waa kharash-oolnimada iyo adkeysiga agabka,tuubo bir ah oo kulul oo dhammaataywaxay noqon kartaa doorasho ku habboon.

Xiga waa habka wax soo saarka ee tuubooyinka birta ah ee kulul ee aan kala go 'lahayn.

Halabuurka Kiimikada ee ASTM A519

Soo-saaraha birta waa inuu falanqeeyo kulaylka bir kasta si uu u go'aamiyo boqolkiiba walxaha la cayimay.

Shaxda 1 Shuruudaha Kiimikada ee Biraha Kaarboon-yar

Shaxda 1aad ee ASTM A519 Shuruudaha Kiimikada ee Biraha Kaarboon-yar

Birta khafiifka ah waa bir leh kaarboon aan caadiyan ka badnayn 0.25%. Sababtoo ah kaarboon yar awgeed, birtani waxay leedahay dabacsanaan iyo dabacsanaan wanaagsan, waana mid aan adkeyn oo ka xoog badan marka loo eego birta kaarboon badan.

Shaxda 2 Shuruudaha Kiimikada ee Biraha Kaarboonka Kale

Shaxda ASTM A519 2 Shuruudaha Kiimikada ee Biraha Kaarboonka Kale

Biraha kaarboonka dhexdhexaadka ah: Iyagoo ka kooban inta u dhaxaysa 0.25% iyo 0.60% kaarboon, waxay bixiyaan adkeysi iyo xoog sare waxayna u baahan yihiin daaweyn kulayl si loo hagaajiyo sifooyinka.

Bir kaarboon sare leh: Waxay ka kooban tahay inta u dhaxaysa 0.60% iyo 1.0% ama ka badan kaarboon, waxayna bixisaa adkeysi iyo xoog aad u sarreeya, laakiin adkeysi hooseeya.

Faa'iidooyinkayaga

Tan iyo markii la aasaasay 2014, Botop Steel waxay noqotay shirkad hormuud u ah soo-saarista tuubooyinka birta kaarboonka ee Waqooyiga Shiinaha, oo loo yaqaan adeeg heer sare ah, alaab tayo sare leh, iyo xalal dhammaystiran. Shirkaddu waxay bixisaa noocyo kala duwan oo tuubooyin bir kaarboon ah iyo alaabooyin la xiriira, oo ay ku jiraan tuubooyin bir ah oo aan kala go 'lahayn, ERW, LSAW, iyo SSAW, iyo sidoo kale saf dhammaystiran oo ah qalabka tuubooyinka iyo flanges.

Alaabteeda gaarka ah waxaa sidoo kale ka mid ah biraha heerka sare ah iyo biraha aan lahayn austenitic, oo loogu talagalay inay daboolaan baahiyaha mashaariicda dhuumaha kala duwan.
