采用粉末镀锌工艺实施油管镀锌，可使油管在腐蚀性介质中获得优越的防腐性能，但其处理过程往往要延续20～22个小时，效率低下，成本高扬，在经济上很不合算。与此相反，采用热扩散液相镀锌工艺实施油管镀锌，不但同样可以提高油管寿命，而且其所需处理时间仅为粉末镀锌的4％， The use of powder galvanized process of the implementation of pipe zinc, tubing can be corrosive medium to obtain superior corrosion resistance, but the treatment process is often to continue for 20 to 22 hours, low efficiency, high cost, economically not cost-effective. In contrast, the use of thermal diffusion liquid zinc plating process of the implementation of tubing zinc, not only can also improve the life of the tubing, and its required processing time is only 4% of the powder galvanized,
