ASTM A53 tuubo bir ah oo aan kala go 'lahaynwaxaa loo kala saaraa A53 Nooca S waana tuubbo bir ah oo aan kala go 'lahayn.
Waxa loo qaybiyaa laba darajo, Darajada A iyo Darajada B, waana ku habboon yahay codsiyada farsamada iyo cadaadiska, iyo sidoo kale isticmaalka guud ee uumiga, biyaha, gaaska, iyo hawada. Tuubada birta ah waa tuubo bir ah oo kaarboon ah oo ku habboon alxanka iyo sameynta hawlgallada oo ay ku jiraan isku-xidhka duubista, foorarsiga, iyo isku-xirka flange.

Tan iyo markii la aasaasay 2014,Birta Botop-ka ahwaxay noqotay shirkad hormuud u ah soo-saaraha tuubooyinka birta kaarboonka ee Waqooyiga Shiinaha, oo caan ku ah adeeg heer sare ah, alaab tayo sare leh, iyo xalal dhammaystiran.
Shirkaddu waxay bixisaa noocyo kala duwan oo tuubooyin bir ah oo 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. Alaabooyinkeeda gaarka ah waxaa sidoo kale ka mid ah birta birta ah ee heerka sare ah iyo birta aan birta lahayn ee austenitic, oo loogu talagalay inay daboolaan baahiyaha mashaariicda dhuumaha kala duwan.
Tuubooyinka birta ah ee ASTM A53 waxay noqon karaan kuwo aan kala go 'lahayn ama la isku qurxiyey.
Habka wax soo saarka ee aan kala go 'lahayn (Nooca S) waa shaqo kulul oo bir ah iyo, haddii loo baahdo, dhammaystir qabow oo ah badeecada tuubada kulul ee la shaqeeyo si loo gaaro qaabka loo baahan yahay, cabbirrada, iyo sifooyinka.
Heerka ASTM A53, shuruudaha ka kooban kiimikada ee Nooca S iyoNooca ETuubooyinka birta ah waa isku mid, halka shuruudaha kiimikada ee Nooca F ay kala duwan yihiin.

Imtixaanka Laabista
Loogu talagalay DN ≤ 50 [NPS ≤ 2], dherer ku filan oo tuubo ah waa inuu awood u leeyahay inuu qallooco ilaa 90° oo ku wareegsan mandrel dhululubo ah, dhexroorkiisuna yahay laba iyo toban jeer dhexroorka dibadda ee la cayimay ee tuubada, iyada oo aan lahayn dildilaacyo qayb kasta.
Laba-xoog-dheer(XXS) tuubo ka sarreysa DN 32 [NPS 1 1/4] looma baahna in lagu sameeyo tijaabada leexashada.
Imtixaanka Fiditaanka
Tuubooyinka birta ah ee aan tolnayn uma baahna in lagu sameeyo tijaabada siman.
Haddii qandaraasku u baahdo, tijaabada waxaa lagu samayn karaa iyadoo la raacayo nidaamka ku jira S1.
Dhammaan cabbirrada tuubooyinka birta ah ee aan kala go'a lahayn waa inay ilaaliyaan qiimaha cadaadiska biyaha ee cayiman iyada oo aan daadanayn ugu yaraan 5 ilbiriqsi.

Cadaadiska tijaabada ee tuubooyinka birta ah ee dunta leh iyo kuwa isku xiran waxaa laga heli karaa Shaxda X2.3.
Waxaa loo isticmaali karaa beddel ahaan tijaabada hydrostatic-ka.
Dhererka oo dhan ee tuubo kasta oo aan tolnayn waa in lagu sameeyaa tijaabo koronto oo aan burburinayn sida waafaqsanE213, E309, amaE570.

Heerka ASTM A53 wuxuu qeexayaa shuruudaha xaaladda tuubooyinka madow iyo dahaarka galvanized ee kulul ee tuubooyinka birta ah.
Tuubo Madow
Tuubada madow waxay tilmaamaysaa xaaladda tuubada birta ah iyada oo aan wax daaweyn dusha sare ah lahayn.
Tuubooyinka madow waxaa badanaa loo isticmaalaa meelaha waqtiga kaydinta uu gaaban yahay, deegaanku uu qalalan yahay oo aan miridhku lahayn, qiimuhuna badanaa wuu hooseeyaa sababtoo ah ma jiro dahaadh.
Dahaarka Galvanized-ka ah ee kulul
Tuubooyinka galvanized, oo sidoo kale loo yaqaan tuubooyinka cad, ayaa badanaa loo isticmaalaa jawi qoyan ama miridhku ku badan yahay.
Zinc-ga ku jira dahaarka zinc-ka wuxuu noqon karaa nooc kasta oo zinc ah oo ku jira ASTM B6.
Tuubada galvanized-ka ah waa inay ka xorowdaa meelaha aan dahaarka lahayn, finan, kaydadka qulqulka, iyo wasakhda guud. Burooyin, muuqaallo, globules, ama kaydad culus oo zinc ah oo carqaladeyn doona isticmaalka loogu talagalay ee walaxda lama oggolaan doono.
Waxyaabaha ku jira zinc-ka oo aan ka yarayn 0.55 kg/m² [1.8 oz/ft²].
Dahaadhada kale
Marka laga soo tago tuubo madow iyo dahaarka galvanized, noocyada dahaarka caadiga ah waxaa ka mid ahrinji, 3LPE, FBE, iwm. Nooca dahaarka ku habboon waxaa loo 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.
