ASTM A335 P5Waa Tuubo Heerkul Sare leh oo Bir ah oo aan kala go 'lahayn oo Ferritic ah oo ka mid ah Heerka Mareykanka. Tuubo Alloy ah waa nooc ka mid ah Tuubo Bir ah oo aan kala go' lahayn, Waxqabadkeedu aad ayuu uga sarreeyaa Tuubada Birta ee aan kala go' lahayn ee Guud, sababtoo ah Tuubada Birta ah ee noocan ah waxay ka kooban tahay C badan, Waxqabadkeedu wuu ka yar yahay Tuubada Birta ee aan kala go' lahayn ee caadiga ah, sidaa darteed Tuubada Alloy waxaa si weyn loogu isticmaalaa Batroolka, Hawada Sare, Kiimikada, Korontada, Kuleyliyaha, Warshadaha Milatariga iyo kuwa kale.

Tuubada Birta Daawaha ah waxay ka kooban tahay tiro badan oo walxood oo aan ka ahayn Kaarboon sida Nikkel, Chromium, Silicon, Manganese, Tungsten, Molybdenum, Vanadium iyo xaddi xaddidan oo walxo kale oo caadi ahaan la aqbalo sida Manganese, Sulfur, Silicon, iyo Fosfooras

Birta Daawaha Guriga ee u dhiganta: 1Cr5MoGB 9948-2006"Heerka Tuubooyinka Birta ah ee aan kala go 'lahayn ee loogu talagalay jajabka batroolka"

• Lacag bixinta: 30% Dhigaal, 70% L/C ama Nuqul B/L ah ama 100% L/C marka la arko
• Tirada Dalabka Ugu Yar: 1 PC
• Awoodda Sahayda: Badeecada Sanadlaha ah ee Tuubada Birta ah ee 20000 Tan

• Waqtiga Hogaaminta: 7-14 Maalmood Haddii Kaydka Ku Jiraan, 30-45 Maalmood In La Soo Saaro
• Baakad: Madow oo baaba'aya, Qallooc iyo Dabool Tuubo kasta; OD ka hooseeya 219mm ayaa loo baahan yahay in lagu xidho xidhmo, Xidhmo kastana aan ka badnayn 2 Tan.

Habka wax soo saarka: Tijaabada Adkaanta:

1. Duub kulul (tuubo bir ah oo aan kala go 'lahayn oo la soo saaray): tuubo wareegsan oo duuban → kuleyl → daloolin → saddex-duub oo iskutallaab ah, duubid joogto ah ama fidin → xoqidda tuubada → cabbirka (ama yaraynta) → qaboojinta → toosinta → tijaabada cadaadiska biyaha (ama ogaanshaha cilladaha) → calaamadaynta → kaydinta

2. Tuubo bir ah oo aan kala go 'lahayn oo sawir qabow (rogid ah): tuubo wareegsan oo billet ah → kuleyl → daloolin → cinwaan → daadinta → qajaar → saliidayn (dahaadhka naxaasta ah) → sawir qabow oo badan (rogid qabow) → tuubo madhan → daawaynta kulaylka → toosinta → tijaabada cadaadiska biyaha (ogaanshaha cilladaha) → calaamadaynta → kaydinta

Baakad:

Baakad qaawan/xidhmo baakad/xirmo baakad/ilaalin alwaax ah labada dhinac ee tuubooyinka oo si habboon loo ilaaliyo si loogu keeno meel u qalanta badda ama sida loo codsado.
