Dhuumaha birta ah ee sida weyn looga isticmaalo adduunka ayaa ah tuubo tayadeedu sarreyso, waxaana si weyn looga isticmaalaa warshadaha, warshadaha kiimikada, dhismaha iyo qeybaha kale.Tuubooyinka birta ah ee aan kala go'a lahayn waxaa doorbida warshadaha sababtoo ah xooggooda sare, caabbinta daxalka, iyo iska caabinta heerkulka sare.Waxa kale oo jira heerar u dhigma marka la eego qeexitaannada iyo dhumucda gidaarka.Kuwa soo socdaa waa liis caalami ah oo tifaftiran tuubooyinka birta ah ee bilaa-xarafka ah iyo heerarka dhumucda gidaarka:
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 10210EN 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 gidaarka:
1. SCH10, SCH20, SCH30, SCH40, SCH60, STD, SCH80, XS, SCH100, SCH120, SCH140, SCH160, XXS, iwm;
2. WT: 2.0-60mm, SCH10S, SCH40S, SCH80S, iwm;
3. Haddii ay dhacdo yaraanta alaabta ceeriin ama baahida weyn, waxaa laga yaabaa in qaar ka mid ah tuubooyinka yaryar ay u baahdaan in loo habeeyo iyadoo loo eegayo baahiyo gaar ah.
Kuwa kore waa qeexitaannada iyo heerarka dhumucda gidaarka ee tuubooyinka birta ee caalamiga ah.Warshadaha kala duwan iyo shuruudaha isticmaalka waxay u baahan yihiin xulashada qeexitaannada u dhigma iyo dhumucda derbiga.Waxaad dooran kartaa qeexitaannada ku habboon baahiyahaaga iibsashada.
