Dhuumaha Tuubooyinka
Hordhac Alaabta
Heerarka agabka:
Tuubooyinka tuubooyinka waxaa sida caadiga ah loo kala saaraa iyadoo lagu saleynayo walxaha ay ka samaysan yihiin, kuwaas oo ay ka mid noqon karaan birta kaarboon, birta daawaha, ama walxo kale. Heerarka walxaha gaarka ah waxay ku xirnaan doonaan arjiga loogu talagalay iyo deegaanka lagu isticmaali doono tuubada tuunbada.
Heerarka wax-soo-saarka:
Habka wax-soo-saarka tuubooyinka tuullaynta waxay u baahan kartaa u hoggaansanaanta heerar gaar ah si loo hubiyo tayada, isku halaynta iyo waxqabadka tuubada. Heerarkaan waxaa laga yaabaa inay soo saaraan ururada sida Bulshada Mareykanka ee Tijaabada iyo Qalabka (ASTM), Machadka Batroolka Mareykanka (API), ama hay'adaha kale ee heer qaran ama heer caalami ah oo khuseeya.
Heerarka Nakhshad:
Tuubooyinka tuubooyinka ayaa laga yaabaa in loo baahdo si ay u buuxiyaan heerarka naqshadeynta qaarkood si loo hubiyo qaabdhismeedkooda hufnaanta iyo culeyska qaadista. Heerarkan waxaa laga yaabaa inay soo saaraan injineernimada iyo ururada dhismaha ama wakaaladaha sharciyeynta dawladda.
Heerarka wax soo saarka:
Habka wax-soo-saarka ee Dhuumaha Biraha-Arc Welded Submerged-Arc wuxuu raaci karaa heerarka gaarka ah ee ay dejiyeen ururada sida Machadka Batroolka Mareykanka (API), Bulshada Mareykanka ee Tijaabinta iyo Qalabka (ASTM), ama ururada kale ee heer qaran ama heer caalami sida soo socota: API 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711, EN10217, EN10219
Shuruudaha Codsiga:
Tuubooyinka tuulan waxaa loo kala saari karaa iyadoo loo eegayo isticmaalkooda loogu talagalay, sida tuulmidda badda, tuulannada aasaaska, ama noocyo gaar ah oo ciidda ama xaaladaha juqraafiyeed. Waa muhiim in lagala tashado heerarka gaarka ah iyo kala-soocidda ee la xidhiidha nooca tuubada tuulan ee looga baahan yahay mashruuc gaar ah. Haddii aad leedahay shuruudo gaar ah ama kala saarid, fadlan xor u noqo inaad bixiso faahfaahin dheeraad ah si aan u bixiyo macluumaad badan oo la beegsaday.

Dusha sare: Fusion bond Epoxy daahan, Dhuxul Tar Epoxy, 3PE, Dahaarka Vanish, Dahaarka bitumen, Daahan saliid madow sida looga baahan yahay macmiilka
Tijaabada: Falanqaynta Qaybaha Kiimikada, Qalabka Makaanikada (xoogga jilicsan ee ugu dambeeya, xoogga wax-soosaarka, Kordhinta), Qalabka Farsamada (Tijaabada Falaxa, Tijaabada Laacidda, Tijaabada Afuufta, Tijaabada Saamaynta), Baadhitaanka Xajmiga Dibadda, Imtixaanka Hydrostatic, Imtixaanka Raajo.
Shahaadada Imtixaanka Mill: EN 10204/3.1B
Shuruudaha Codsiga: Tuubooyinka alxanka dheer ayaa sidoo kale lagu kala saari karaa iyadoo lagu saleynayo isticmaalkeeda loogu talagalay, sida dhuumaha saliidda iyo gaaska, codsiyada qaab dhismeedka, ama isticmaalka guud ee warshadaha. Hubi inaad tixraacdo heerarka gaarka ah iyo kala-soocidda ee khuseeya shuruudahaaga gaarka ah, maadaama ay ku kala duwanaan karaan iyadoo ku saleysan warshadaha iyo gobolka.
