Generally, trenched will be excavated for pipe laying or conduits and cables installing. While, in some case that trenching is not practical for geographic factors or environmental reasons, directional boring, usually known as horizontal directional drilling(shortened as HDD) will be applied. HDD is a typical example of trenchless technology which means using a surface-launched Drilling Waste Management to bore a path for installing infrastructure such as pipelines, gas lines, oil line, sewer lines, water lines, power cable conduits, and telecommunication. HDD is normally applied when a river, road, landscape, or a congested place needs to cross for pipe and cable laying. Until now, installation length by HDD has been up to 2000 meters, and diameters up to 1200 mm have been finished in short length. Yet, that does not necessarily mean that HDD can be adopted for all road-cross or river -cross drilling. Actually, solids rock or sedimentary rock is the most suitable material. HDD is used instead of other techniques mainly for the following benefits. HDD not only makes traffic disruption less and deeper or longer installation possible, but ensures a lower cost and environmentally safer.
GN Solid America is specialized in design and build up mud recycling system for HDD rigs, and for a decade’s innovating and evolving, GN’s mud system is widely used in Australia, India, and other countries for HDD rigs. The below features are proof of GN’s mud systems popularity. Firstly, GN provides compact design with a combination of mud cleaner and underflow shaker, which is double deck for the first stage separation and drilling mud’s drying.
Secondly, GN supplies a full range of mud system:150/ 350/ 800/1000/1500GPM.
Thirdly, GN offers cost effective equipment integration from a single source: GN Solids Control factory.
