LSAW Pipe(Longitudinal Submerged Arc-Welding Pipe), wanda kuma ake kiraSAFL bututu.Yana ɗaukar farantin karfe a matsayin ɗanyen abu, a ƙera shi ta na'urar gyare-gyare, sannan a yi walda mai ɓarna mai fuska biyu.Ta wannan tsari, bututun ƙarfe na LSAW zai sami kyakkyawan ductility, walƙiya tauri, daidaituwa, filastik da babban rufewa.
Matsakaicin diamita na LSAW ya fi ERW girma, yawanci daga 406mm zuwa 2020mm.Kyawawan wasan kwaikwayo akan juriya mai tsayi, da juriya mai ƙarancin zafin jiki.
SSAW Pipe(Spiral Submerged Arc-welding Pipe), wanda kuma ake kiraHSAW tube(Helical SAW), layin walda kamar heliks.Yana amfani da fasahar walda iri ɗaya na Submerged Arc-Welding tare da bututun LSAW.Daban-daban bututun SSAW ana waldashi ne a karkace inda LSAW ke waldadden tsayin daka.Tsarin masana'anta yana jujjuya tsiri na ƙarfe, don yin jagorar juyawa yana da kwana tare da jagorar cibiyar bututu, kafawa da walƙiya, don haka kabu ɗin walda yana cikin layi mai karkace.
Matsakaicin diamita na SSAW yana daga 219 mm zuwa 2020 mm. Abinda ke da amfani shine za mu iya samun nau'in diamita daban-daban na bututun SSAW tare da girman girman nau'in karfe, akwai aikace-aikace mai fadi don albarkatun kasa na karfe, da kuma waldi. ya kamata ku guje wa damuwa na farko, ayyuka masu kyau don ɗaukar damuwa.
