2、普通碳素鋼電線套管(GB3640-88)是工業與民用建築、安裝機器設備等電氣安裝工程中用於保護電線的鋼管。
3、直縫電焊管(YB242-63)是焊縫與鋼管縱向平行的鋼管。通常分為公制電焊管、電焊薄壁管、變壓器冷卻油管等等。
4、承壓流體輸送用螺旋縫埋弧焊管(SY5036-83)是以熱軋鋼帶卷作管坯,經常溫螺旋成型,用雙面埋弧焊法焊接,用於承壓流體輸送的螺旋縫鋼管。鋼管承壓能力強,焊接性能好,經過各種嚴格的科學檢驗和測試,使用安全可靠。鋼管口徑大,輸送效率高,並可節約鋪設管線的投資。主要用於輸送石油、天然氣的管線。
5、承壓流體輸送用螺旋縫高頻焊管(SY5038-83)是以熱軋鋼帶卷作管坯,經常溫螺旋成型,採用高頻搭接焊法焊接的,用於承壓流體輸送的螺旋縫高頻焊鋼管。鋼管承壓能力強,塑性好,便於焊接和加工成型;經過各種嚴格和科學檢驗和測試,使用安全可靠,鋼管口徑大,輸送效率高,並可節省鋪設管線的投資。主要用於鋪設輸送石油、天然氣等的管線。
6、一般低壓流體輸送用螺旋縫埋弧焊鋼管(SY5037-83)是以熱軋鋼帶卷作管坯,經常溫螺旋成型,採用雙面自動埋弧焊或單面焊法製成的用於水、煤氣、空氣和蒸汽等一般低壓流體輸送用埋弧焊鋼管。
