Pickling & Passivation

 

Pickling and Passivation: Useful for removing weld color or scale from the surface of steel, pickling is the non-selective removal of surface contaminants or "etching". Passivation must be performed after pickling to ensure proper passive layer formation.

Do it with excellence or not at all.
From equipping our Project Leaders with laptop computers allowing them to operate more efficiently with up-to-date information at their fingertips to having a dedicated Safety Director ensuring safety compliance and advancing a culture of accident prevention, every decision we make is made with excellence in mind.  Why?  Because excellence is our standard - a standard never compromised.  We believe every element that affects our customers' experience needs to withstand the demands of excellence, right down to the valves and hoses we purchase.  After all, when your goal is to deliver a service experience not found anywhere else, sometimes the smallest details could have the most profound effects.
