Spiral welded pipe belongs to the category of welded steel pipes, named after the presence of a spiral shaped weld on both sides. The superior structural characteristics of double-sided submerged arc spiral welded steel pipes determine that they are increasingly widely used in fields such as water conservancy, chemical industry, petroleum, and thermal power industry. And the research on spiral tube technology has involved various aspects such as flow pattern research, pressure drop characteristics research, and enhanced heat transfer research.
螺旋焊管属于焊接钢管的范畴,因内外(双面)各有一条螺旋形状的焊缝而得名。双面埋弧螺旋焊接钢管优越的结构特性决定了它在水利、化工、石油及热电工业等领域日益得到广泛应用。并且螺旋管技术研究已涉及到流型研究,压降特性研究,强化传热研究等诸方面。双面埋弧螺旋焊接钢管与圆钢等实心钢材相比,在抗弯抗扭强度相同时,重量较轻,是一种经济截面钢材。
双面埋弧螺旋焊接钢管主要应用于自来水工程、石化工业、化学工业、电力工业、农业灌溉、城市建设。钢管承压能力强,塑性好,便于焊接和加工成型;一般低压流体输送用螺旋缝埋弧焊钢管,采用双面自动埋弧焊或单面焊法制成的用于水、煤气、空气和蒸汽等一般低压流体输送用埋弧焊钢管。它的强度一般比直缝焊管高,能用较窄的坯料生产管径较大的焊管。
