As the offshore mud tank system manufacturer in China, we can design customized mud tank system for onshore and offshore drilling.
Recently we shipped one set of offshore mud tank system to our client, it consist of one unit of shale shaker, one unit of mud cleaner, one unit of decanter centrifuge , one unit of submersible slurry pump as feeding pump of decanter centrifuge, 2 units of centrifugal pump as feeding pump of mud cleaner desander cone and desilter cone. The shaker screen size of shale shaker and mud cleaner underflow shale shaker is same for easy stock of shaker screens, the composite material shaker screens is proved with at least 20% longer working life than the steel frame shale shaker.
Shale shaker is the first phase cleaning equipment to separate coarse solids and reduce the solids content, the performance of the shale shaker is better, the drilling waste is less, the working life of the desander cone is longer, the working life of centrifugal pump is longer.
The desander cone is the second phase cleaning equipment to separate cut point over 75 microns.
The desilter cone is the third phase cleaning equipment to separate solids cut point over 25 microns.
The decanter centrifuge is the fourth phase cleaning equipment to separate the fine solids cut point 2~5 microns. Features of GN decanter centrifuge:
1) Bowl material is made of duplex stainless steel 2205 or 2304 by centrifugal casting, the screw is made of stainless steel by heat treatment up to 1000 degree, the opening propeller design increase the treating capacity.
2) The solids discharge port and fluids distribution port is protected by tungsten alloy, the screw impeller is protected by tungsten carbide tiles, the scraper and side scraper is also installed to protect the solids discharge port and bowl.
3) The collection box is made of stainless steel material for better abrasion resistence.
