3.0 Project opportunities
Reduction in lead time of the spools is reduced to 6 weeks by stocking the flanges, tiles and elbows required for bends in Rexline Engineering Facilities.
Extending the life of bends more than 12 weeks by using increased percentages of Alumina compositions in tiles (Proposed compositions: 95%)
To enhance the life of 76-degree bends, the life and wear of the previously installed bends were studied and proposal to change the design of lining to incorporate the concentrated wear patterns caused by variation in flow quantity
4.0 Asset Reliability& Monitoring
The product was monitored in site periodically to analyse the product performance and product engineering improvisations. The following are the observations.
4.1 First Month Inspection
4.2 Second Month Inspection (Previous Bends Life Expectancy)
4.3 Third Month Inspection
5.0 Observations & Results
Rexline Engineering Mining’s pre-engineered ceramic tiles have increased the life expectancy of the bends by 66% resulting in a total life of 12 weeks whereas the previously existed bends lasted 8 weeks. The project lead time of 8 weeks was further reduced to 6 weeks by stocking flanges, tiles and required elbows in Rexline Engineering facilities.
