ASTM A 53 waxay dabooshaa tuubo bir ah oo aan fiicneyn oo alxan leh oo dhumucdiisuna tahay gidaarka.Xaaladda dusha sare sida caadiga ah waa madow, ASTM A53 (sidoo kale loo yaqaan ASME SA53 tube) waxaa loogu talagalay codsiyada farsamada iyo cadaadiska sidoo kale waa la aqbali karaa isticmaalka caadiga ah ee uumiga, biyaha, gaaska iyo khadadka hawada.Waxay ku habboon tahay alxanka iyo samaynta hawlgallada ku lug leh duubista, foorarsiga, iyo flanging.A53 tube birta aan fiicnayn waa shay ka mid ah tuubooyinka birta caadiga ah ee Maraykanka.Habka ugu muhiimsan ee wax soo saarka ee tuubooyinka birta ee A53 waxay u qaybsan tahay sawir qabow iyo duub kulul.Farqiga ugu weyn ee u dhexeeya labadooda ayaa ah in habka wax soo saarka ee tuubooyinka birta ee qabowga duuban ay guud ahaan aad uga dhib badan yihiin kuwa kululaynta, iyo muuqaalka tuubada qabow ee duuban ee birta ah ayaa ka gaaban kan kululaynta.Tuubooyinka birta ah ee duuban ee duuban, dhumucda gidaarka qabow-rogid ee birta kaarboonka ee bilaa tolmoon ayaa guud ahaan ka yar tan tuubooyinka birta kaarboonka ee duuban ee kulul, laakiin dusha sare ayaa u muuqda mid ifaya.Dusha sare ee tuubada birta kaarboon ee kulul-rogid waa mid aad u qallafsan.Habka ugu muhiimsan ee wax soo saarka wareega tube maran → kululaynta → daloolin → saddex-roll rogid rogid, si joogto ah u rogid ama extrusion → saarista tuubada → cabbirka (ama yaraynta dhexroor) → qaboojinta → toosan → hydraulic test (ama ogaanshaha cillad) → calaamadaynta → maktabadda gelin.

1. Habka ugu muhiimsan ee wax-soo-saarka tuubada birta ah ee kulul ee duuban (habka kormeerka ugu weyn):
Diyaarinta iyo kormeerka tuubada banaan → tuubo kuleyl banaan → daloolin → tuubo rogroga → birta dib u kululaynta → daawaynta kulaylka go'an (la dhimay) dhexroorka → daawaynta kulaylka △ → dhamaystirka tubada toosinta → dhamaystirka → kormeer (aan burburin, jireed iyo kiimiko, Kormeerka Taiwan) → bakhaarka
2. Habka ugu muhiimsan ee wax soo saarka ee tuubooyinka birta ee qabow-duuban (la sawiray):
Diyaarinta billet → Saliid qajaar → duubid qabow (sawir) → daawaynta kulaylka → toosin → dhammayn → kormeer
