A NEW PATENT
THE HUG (Helical Unique Generation) is a new good, which has never been seen before. It substantially deviates from any other good or service produced before. Over the past decades, no major breakthroughs have occurred in the basic machinery of Pipeline Rehabilitation to solve the problem of pipeline corrosion.

Average 250 Pipeline Accidents Each Year: Billions Spent on Property Damage
THE NEED: Corrosion remains the number one problem in the industry. The Saudi Arabian Oil Company (Saudi Aramco) is the state-owned oil company of the Kingdom of Saudi Arabia. It is among the leading producers of natural gas, and monitors and controls a 20,000 km pipeline network. The problem of corrosion took precedence in the latest pipeline conference this summer in Saudi Arabia: one third of the time was allocated to this problem.
THE HIGH COST OF REHABILITATION: In January 2010, UAE-based construction firm, Dodsal, won a contract for the replacement of a 100 km, 36 inch diameter pipeline linking Abu Dhabi, worth approximately $US 85 million: $US 8.5 million/km. The HUG Thermoplastic Liner would have cost 25% to 33% less: $56.6million to $US64 million– a saving up to $US21 million and still would have generated a very high profit margin.
Among the largest producing regions, the Middle East is also the fastest growing market for pipelines. The region will expand by 42% in construction length and 63% in expenditure over the next 5 years. Why not install a HUG Thermostatic Liner in all the new pipeline networks to extend their lifetime to 50 years for a reasonable extra cost?*
THE COMPETITION: There are presently other HDPE liners. The power roller compresses these liners to provide an optimum of a 0.5 inches gap inside the carrier pipeline. This gap closes upon use and the new liner becomes supported by the steel pipeline. The difficulty is that the gap is too small and consequently the maximum distance for rehabilitation of a large dimension pipeline is 800m. This short distance is caused by the friction of the weight of the liner as it is forced along the corrosive pathway of the carrier pipeline. There is no room for adding a lubricated ‘slip slide’. (If the compression exceeds a 0.5 inches gap, the memory of the HDPE pipe is loss.) Continue reading PIPELINE CORROSION FINALLY SOLVED 2
