ASTM A53 tuubo bir ah oo aan xuduud lahaynwaxaa loo kala saaraa sida A53 Nooca S waana tuubo bir ah oo aan kala go 'lahayn.
Waxay u qaybsantaa laba darajo oo kala ah darajada A iyo darajada B, waxayna ku haboon tahay farsamooyinka iyo cadaadiska, iyo sidoo kale isticmaalka guud ee uumiga, biyaha, gaasta iyo hawada.Dhuumaha birta ah waa tuubbo bir kaarboon ah oo ku habboon alxanka iyo samaynta hawlgallada ay ka mid yihiin xidhidhiyaha, foorarsiga, iyo isku xirka flange.

Tan iyo markii la aasaasay 2014,Botop Steelwaxay noqotay shirkad hormuud u ah tuubbooyinka birta kaarboon ee Waqooyiga Shiinaha, oo caan ku ah adeeg aad u wanaagsan, alaab tayo sare leh, iyo xalal dhammaystiran.
Shirkaddu waxay bixisaa noocyo kala duwan oo ah tuubooyinka birta kaarboonka iyo alaabada la xidhiidha, oo ay ku jiraan kuwa aan fiicneyn, ERW, LSAW, iyo tuubada birta ee SSAW, iyo sidoo kale saf buuxa oo ah xirmooyinka tuubooyinka iyo flanges.Alaabooyinkeeda gaarka ah waxa kale oo ka mid ah alloys-ga sare iyo biraha austenitic ahama, oo loogu talagalay in lagu daboolo baahiyaha mashaariicda dhuumaha ee kala duwan.
ASTM A53 tuubooyinka birta ah waxay noqon karaan kuwo aan fiicneyn ama alxan.
Habka wax-soo-saarka (Nooca S) ee aan kala go 'lahayn waa shaqo kulul oo bir ah iyo, haddii loo baahdo, qaboojin dhammayn ah oo ku saabsan badeecada tuubada kulul ee ka shaqeysa si loo gaaro qaabka loo baahan yahay, cabbirka, iyo guryaha.
Heerka ASTM A53, shuruudaha halabuurka kiimikada ee Nooca S iyoNooca ETuubooyinka birta ah waa isku mid, halka shuruudaha ka kooban kiimikada ee Nooca F ay kala duwan yihiin.

Qallooca Tijaabada
Loogu talagalay DN ≤ 50 [NPS ≤ 2], Dherer ku filan oo tuubo ah waa in ay awood u yeelataa in lagu qaloocdo qabow iyada oo loo marayo 90 ° agagaarka mandrel cylindrical, dhexroor kaas oo ah laba iyo toban jeer dhexroorka bannaanka ee tuubada, iyada oo aan la samayn dildilaaca qayb kasta.
Laba-dheeraad-xoog leh(XXSDhuumaha ka sarreeya DN 32 [NPS 1 1/4] uma baahna in la marsiiyo baaritaanka qalooca.
Tijaabada fidsan
Tuubooyinka birta ah ee aan xumaanta lahayn uma baahna in lagu sameeyo tijaabada fidsan.
Haddii loo baahdo qandaraasku, tijaabada waxaa loo samayn karaa si waafaqsan nidaamka S1.
Dhammaan cabbirrada tuubooyinka birta ee bilaa-xannida ah waa inay ilaaliyaan qiimaha cadaadiska biyaha qaarkood iyagoon daadin ugu yaraan 5 ilbiriqsi.
Cadaadiska tijaabada ee tuubooyinka birta ee bannaan-dhamaadka ah waxaa laga heli karaa shaxda X2.2.
Cadaadiska tijaabada ee tuubooyinka dunta ah iyo kuwa isku xidhan waxa laga heli karaa shaxda X2.3.
Waxa loo isticmaali karaa beddelka tijaabada hydrostatic.
Dhererka oo dhan ee tuubo kasta oo aan cillad lahayn waa in lagu sameeyaa tijaabo koronto oo aan waxyeello lahayn si waafaqsanE213, E309, amaE570.

Heerka ASTM A53 wuxuu qeexayaa shuruudaha xaaladda tuubada madow iyo daahan galvanized kulul ee tuubooyinka birta.
Dhuumaha Madow
Dhuumaha madow waxaa loola jeedaa xaaladda birta birta iyada oo aan wax daaweyn ah dusha lagala socon.
Tuubooyinka madow waxaa inta badan loo isticmaalaa meelaha waqtiga kaydinta gaaban yahay, deegaanku waa qalalan oo aan qudhun, qiimuhuna inta badan waa ka hooseeyaa sababtoo ah ma jiraan wax dahaadh ah.
Dahaarka Galvanized ee kulul
Tuubooyinka galvanized, oo sidoo kale loo yaqaan tuubooyinka cad, ayaa badanaa loo adeegsadaa meelaha qoyan ama daxalka leh.
Zinc ku jira daahan zinc wuxuu noqon karaa heer kasta oo zinc ah oo ku jira ASTM B6.
Dhuumaha galvanized waa in ay ka xoroobaan meelaha aan dahaadhka lahayn, finan yaryar, kaydka qulqulka, iyo wasakhda guud ee ku darida.Burooyinka, saadaalinta, globules, ama kaydadka culus ee zinc oo faragelin doona isticmaalka loogu talagalay isticmaalka walaxda lama oggolaan doono.
Waxa ku jira Zinc oo aan ka yarayn 0.55 kg/m² [1.8 oz/ft²].
Dahaarka kale
Marka lagu daro tuubada madow iyo dahaarka galvanized, noocyada daahan caadiga ah waxaa ka mid ahrinji, 3LPE, FBE, iwm. Nooca dahaarka ku habboon waxaa lagu dooran karaa iyadoo loo eegayo shuruudaha gaarka ah ee jawiga hawlgalka.
Bixinta macluumaadka soo socda waxay ka dhigi doontaa habka wax iibsigaaga mid hufan oo sax ah.
Magaca caadiga ah: ASTM A53/A53M;
Tirada: Wadarta dhererka ama tirada guud;
Fasalka: Fasalka A ama Fasalka B;
Nooca: S, E, ama F;
Daaweynta dusha sare: madow ama galvanized;
Cabbirka: Dhexroorka ka baxsan, dhumucda gidaarka, ama jadwalka Lambarka ama darajada miisaanka;
Dhererka: dherer cayiman ama dherer aan toos ahayn;
Dhamaadka tuubbada: dhammaadka cad, dhammaadka jeexan, ama dhammaadka dunta leh;
