(1) tuubooyinka alxanka ah ee ka soo alxanka saxan birta galay tuubada wareega, qaybsan inta jeer sare iska caabin welded tuubo (ERW tuubada welded), tollayn toosan arc alxanka tube (LSAW), spiral tube welded.Electrical injineernimada leh "SC", waxaa loo isticmaali karaa maadaama dhuumaha gaaska biyaha sidoo kale loo isticmaali karo sida tuubada dunta, oo dhumucdeedu yar tahay.

(2) Dhuumaha dhuumaha, sidoo kale loo yaqaano tuubada siliga, waa yara dhuuban, waxaa tilmaamaya "T", waxaana loo isticmaali karaa oo kaliya dunta.

(3) Tuubbada ERW waa "tubo birta iska caabin ah inta jeer ee soo noqnoqda", iyo habka alxanka caadiga ah waa ka duwan yahay, line alxanka waa ka alaabta aasaasiga ah ee suunka birta jirka dhalaalay, xoogga farsamo waa ka fiican yahay alxanka guud.ERW taagan alxanka iska caabinta, alxanka iska caabin ah wuxuu leeyahay sifooyinka waxtarka wax soo saarka sare, qiimaha jaban, badbaadinta alaabta iyo qalabaynta fudud, sidaas darteed waxaa si ballaaran loo isticmaalaa duulista, hawada, tamarta, elektiroonigga, baabuurta, warshadaha iftiinka iyo qaybaha kale ee warshadaha, waa mid ka mid ah hababka alxanka muhiimka ah.

Habka wax soo saarka ee tuubada birta ee ERW:
