P-Lining is a new advanced refractory lining system that significantly reduces the stresses on refractory anchors.  Due to the lower anchor stresses the probability of anchor failure due to creep rupture is extremely low.  

Failure of steel refractory anchors in process vessels, particularly in two layer systems, comprising an insulation layer and hot face is still a major concern for industry resulting in the loss of millions of dollars in downtime.  Two dominant failure modes exist and can be described as creep rupture and yielding of the steel anchor. 

Creep rupture is due to a small constant load on the anchor and this could be the weight of the refractory castable and/or the thermal load during operation.  Creep rupture is one of the most important failure mechanisms as small stresses at high temperatures on anchors can results in catastrophic failure.

To date, the dimensionality of the anchor and refractory layers has not been considered critical and design has been based on experience.    Our research, based on metallurgical analysis and numerical modelling of failed linings. 

Unexpected refractory failures incur costs to industry ranging from $500,000 per day to as high as $7,000,000 per day.  The sophisticated P-Lining (patented pending) refractory lining system can significantly reduce the risk of refractory lining failures enabling licensees to increase plant operating time and lower maintenance cost due to longer lining life.
