Tuubada birta ah ee aan kala go 'lahayn ee si weyn looga isticmaalo adduunka waa tuubo tayo sare leh waxaana si weyn loogu isticmaalaa warshadaha, warshadaha kiimikada, dhismaha iyo meelaha kale. Tuubooyinka birta ah ee aan kala go'lahayn waxaa doorbidaya warshaduhu sababtoo ah xooggooda sare, iska caabbinta daxalka, iyo iska caabbinta heerkulka sare. Waxaa sidoo kale jira heerar u dhigma marka loo eego qeexitaannada iyo dhumucda derbiga. Kuwa soo socda waa liis qeexaya tuubooyinka birta ah ee aan kala go'lahayn ee caalamiga ah iyo heerarka dhumucda derbiga:
Tilmaamaha:
1. Heerarka Mareykanka:ASTM A106, ASTM A53, API 5L, ASTM A192,ASTM A210, ASTM A213iwm.;
2. Heerarka Jabbaan: JIS G3454, JIS G3455, JIS G3456, JIS G3461, JIS G3462, iwm;
3. Heerarka Jarmalka: DIN 1626, DIN 17175, DIN 2448, DIN 2391, iwm;
4. Heerarka Ingiriiska: BS 1387, BS 3601, BS 3059, BS 6323, iwm.;
5. Heerarka Yurub:EN 10210, EN 10216, EN 10297, iwm.;
6. Heerarka Shiinaha:GB/T 8162, GB/T 8163, GB/T 3087, GB/T 5310, GB/T 6479, iwm.
Heerka dhumucda derbiga:
1. SCH10, SCH20, SCH30, SCH40, SCH60, STD, SCH80, XS, SCH100, SCH120, SCH140, SCH160, XXS, iwm;
2. Miisaanka: 2.0-60mm, SCH10S, SCH40S, SCH80S, iwm.;
3. Haddii ay jirto yaraanta alaabta ceeriin ama baahi weyn, waxaa laga yaabaa in tuubooyinka yaryar qaarkood loo baahdo in loo habeeyo iyadoo loo eegayo baahiyaha gaarka ah.
Kuwa kor ku xusan waa qeexitaannada iyo heerarka dhumucda derbiga ee tuubooyinka birta ah ee caalamiga ah ee aan kala go 'lahayn. Warshadaha kala duwan iyo shuruudaha isticmaalka waxay u baahan yihiin xulashada qeexitaannada u dhigma iyo dhumucda derbiga. Waxaad dooran kartaa qeexitaannada ku habboon baahiyahaaga iibka.
