Forming hydrophilic metallic surfaces for e.g. heavy oil transport pipes, by e.g. sanding, metallic surface to minimize contact angle and adherence of oil on same surface

NOVELTY – The metallic surface is mechanically processed using e.g. sanding, so that the contact angle and adherence of ultra-viscous oil on the same surface are minimized. The metallic surface is also made hydrophilic. USE – For forming hydrophilic metallic surfaces for e.g. heavy oil transport pipe. ADVANTAGE – Ensures smooth, trouble-free oil transport through pipe for long period of time without clogging or using chemical reagents.
