Technical Field
[0001] This utility model belongs to the field of titanium tube processing technology, and specifically relates to a coating spraying device for the outer surface of titanium tubes. Background Technology
[0002] Titanium alloy pipes are pipes made of titanium alloy, possessing high mechanical properties, excellent stamping performance, and the ability to be welded in various forms. The strength of the welded joint can reach 90% of the strength of the base metal, and it also has good machinability. However, in certain special environments, titanium alloy pipes are prone to corrosion if subjected to abrasion, thus reducing their service life.
[0003] In existing technologies, conventional spraying equipment is complex to operate and lacks stability when clamping titanium alloy pipes, resulting in low process efficiency. When spraying titanium pipes, if the pipe is too long, it becomes difficult to clamp and spray, and it also hinders workers from moving the pipe after spraying, leading to reduced spraying effectiveness and impacting subsequent use.
