When corrosion happen on the decanter centrifuge.......

The purpose and the function of decanter centrifuge is to separate liquid our from solid and/or oil.  Some slurry which might contain materials that might cause the corrosion via contact with metal.  In the long-run of time, it will affects the work ability by decrease the performance  that lead less operation time.  When corrosion start to appear it and deal with timely matter, it can solve the problem without cause much of operation delay. 

By collective feedback on the operation field, corrosion can be spot-alike and evenly -formed.  The spot-alike or random pattern-like corrosion only happened on random area.  The evenly-formed corrosion is more serious issue that might leave the decanter centrifuge out of commission pre-maturely.  Random and spot-alike corrosion often happened due to the defects on the surface of metal.  The more serious and destructive elements that contain in the slurry flow into the decanter centrifuge and without after-work clean-up, it will slowly created the hole on the metal. If the decanter centrifuge is not for conservation, the corrosion action will become more and more serious.

Corrosive wear is a relatively common -happened corrosion. This kind of corrosion is not serious spot-alike corrosion, but in the centrifuge maintenance work, it needs to pay attention to.  This wear corrosion is due to friction parts in the work. When maintenance, the bearing can give parts contact daub lubricating oil, help to reduce friction, regularly will more serious wear parts are replaced, which can effectively prevent the corrosion wear.

GN Solids America LLC has a large warehouse get to 30, 000 sq. feet. GN Solids America helps to keep many decanter centrifuges are available in Houston. GN Solids America is providing rental services for these centrifuges and the some other solids control and drilling waste management systems. Different kinds are optional from varying speed to fix speed.

Dewatering System for Water Hammer

Not only drilling, whenever there is a construction work, or some work, there must be some waste generated, planning before proceed have been more and more important. Some clients who is using water hammer, also is going to do with the waste, and reuse the water.

As we all know there are 4 basic rules of waste handling to make it envronmental friendly. Reduce, reuse, recycle, recover. For water hammer, one of the most important reason is we need to recyle and reuse the clean water.

Reuse – solids control equipment is key to the reuse strategy.  Poor solids control efficiencies will lead to more solids entering the active system, further reducing their particle size, and ultimately resulting in the requirement to dump, or to dilute, thereby increasing volumes and costs, all of which have a negative environmental impact. 

The water hammer which is normally more expensive than the normal drilling rig, especially for the use of the water, not drinking water but need to be as clean as possible.

Therefor now we are deliverying one system to Europe, which is used for water hammer project. Containing:

1) Double deck shale shaker: GN double deck shale shaker can remove the solids in very good performance, top section screen with sieve screens remove most of the big particles. 

2) Decanter centrifuge: GN decanter centrifuge is used to remove the fine solids, min separation points about 2-5microns. Sometimes it need to be used with polymer, the dewatering unit, to make sure we get the better result.

3) Screw pump: screw pump feed for centrifuge. The pump from GN is made by German Netsch, NEMO pump makes sure the performance of centrifuge feeding.

4) Mud tank skid: All equipment is mounted on one mud tank, which is also able to be customized. Normally minimum requirement is to lower the transportation cost. 

Keep tune to GN news, then we can keep you updated on the on site performance.

GN Own Brand Shaker Screen used on GNZS Series Shale Shaker

GN Solids Control is an API certified manufacture for drilling mud solids control equipment. No doubt, the shale shaker unit is one of the most important equipment in our production line, in the meanwhile, shale shaker is the most important primary solids control equipment that takes place in the role of separating the coarse solids in the drilling mud as the first stage solids control equipment.

The function of shale shaker to separate the solids should give credit to the mesh screen fixing on the shale shaker unit. By using different mesh screen, the shale shake unit could do separation process on different slurry. GN now has 3 main size shale shaker unit, each of them is equipped with GN self designed and manufactured shaker screen. The shale shaker models are GNZS752, GNZS703 and GNZS 594, respectively fixed with 2 panel, 3 panel and 4 panel screens.

From the shale shaker model, we can find some hints of the dimension of the screen. The screen used of the shaker model 752 is 750x900mm. This shale shaker is widely used in some small capacity no dig drilling project and core drilling solids removal unit. Thus, this shaker model is also baby shaker. The shaker 703 is fixed with screen dimension of 700x1250mm; this shaker model is widely used in oil drilling and some big capacity HDD project. Based on the model GNZS703, GN does have the shaker model GNZS706 with 2 layers shaker deck, and 6 pieces screen fixed. And the GNZS705 model is often used as underflow shaker for a mud cleaner unit to further dry the solids discharged from cyclone units. While the shaker model GNZS594 is fixed 4 pcs screen with dimension of 585x1165mm. This model could be used as a primary shaker in solids control system, and it can also be used as high G force drying shaker in waste cuttings drying system. What we need do is to use two high power vibrators. 

Guess through this article, the client would be easily to choose GN’s shaker screen if you already had GN’s shale shaker in hand. Besides, GN can also provide replacement screen for many other brands shale shaker that widely used in the industry. Just let us know once you have the request for the shaker screen.

What is "IECEX/A-TEX" mark on GN Solids America’s solids control machines?

Oil rig drilling is world-wide operation and solids control machinery and system is manufacture t that it can be operate on any corner of the world, land and sea alike.  As been one of the most hazard working- area condition, the electronic parts of machinery often marked "IECEX/A-TEX".  This is the certificate marked as Hazardous Area Certifications.  The mainstream mark is IECEX which is international which every country accept the standard while ATEX is European standard but most countries are accept the standard as well. 

Explosive atmospheres can be caused by possible burning gases, mists, vapors or by combustible dusts, in combination with oxygen. With a certain concentration density all that is needed to cause an explosion is a source of fire cause by heat and spark.

ATEX or IECEX certified machinery will secure the operators and its machinery assets that under no matter in any working condition it will not cause an ignition so in conclusion it is safe, end of discussion.  The standard divided into different zones that ID potential hazardous atmosphere in the area.

ATEX based on the requirements of two European Directives:

1.  Directive 99/92/EC (also known as ‘ATEX 137’ or the ‘ATEX Workplace Directive’) is minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.

2.  Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive’) on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

What IECEX Scheme is an international Conformity Assessment Scheme covering Electrical Equipment for Explosive Atmospheres, as the internationally accepted means of demonstrating conformity with IEC Standards prepared by IEC TC31.

ATEX standard is about enabling to trade in European countries. Its purpose is to establish a level of safety which is to be regarded it is sufficient to ensure European authorities would accept the equipment certified.  

Difference compare with ATEX, the IECEX is about giving confidence that a product or service meets clearly defined transparent criteria. By providing its transparency with a high level of confidence, it is intended that it will eventually provide a worldwide recognized and acceptance certificate in which the whole world has confidence. The driving force is safety, with the trade benefits following from the confidence.
