mud system

GN Solids Control is world famous manufacturer for mud recycling system for HDD, CBM, piling, underground instruction, trenchless, dredge slurry separation, etc…
GN Solids Control also offers customized solution per customer’s condition. A customer request 500GPM mud system for HDD rig. Below are their requirements on equipment for the 500GPM mud system. GN Solids Control gives solution relatively to optimize the mud system for HDD rig:
1) Customer request on 500GPM mud tank dimension: Mud tank to same as 20 ft standard O.T. container.( Standard frame with container corners for transport on containers vessels and for quick lifting)
GN Solution on the 500GPM mud system tank dimension: It is no problem for exactly same dimension with 20ft container. But GN recommends the tank with a smaller width: 2000mm in order to put into container for shipment.
2) Tank compartment for the 500GPM mud system: Divide the 20 ft mud tank to three chambers – (1) Shale shaker chamber, (2) De-sander chamber, (3) Desilter chamber
GN confirms the 3 chamber of the 500gpm mud tank system
3) Customer request to install bigger shale shaker model GNZS594E with 616 GPM.
GN team confirms the big shaker for 500GPM mud system.
4) Furthermore, customer request install 2 Nos. of big power pump 6×5 centrifugal pump with 45 Kw motor.

And install big capacity mud cleaner (shaker + 2 nos. of de-sander + 12 Nos. of desilter) model GNZJ594E-2S12N with 1056 GPM capacity.
Per the big centrifugal pump and big capacity mud cleaner, GN engineer give solution that: connection shale shaker with mud cleaner shaker with distribution box, controlled by valve, customer can choose to use 1 shaker or 2 shakers. In this case, the mud system can extend to be with 500GPM capacity or 1000GPM capacity.
During 500GPM capacity, the user blocks half of desander cone and half of desilter cone for a better hydraucyclone separation.
5) Regarding mixing system, as customer already have some mud tanks locally, GN offers a separate jet mud mixer for option. Customer can chose it to match with its local mud mixing tank. Or connect the shale shaker tank with its original mud tanks.
The system is easy to shift between 500gpm and 1000gpm capacity. Customer is very happy with professional engineering team of GN Solids Control.
If you have interest on above 500 / 1000 GPM HDD mud system, or you have any special request on no-dig compact mud recycling system, you can contact GN group freely for more information.

General information of flexible rubber coupling

Flexible rubber coupling, is also called as flexible connection, Soft rubber connector, soft rubber joints, flexible rubber joints, flexible rubber joints , rubber shock absorbers. The flexible coupling is mainly composed of the inner and outer rubber layer, Kordeinlage (ply) and steel rings, they form tubular rubber, under high temperature and pressure, then after vulcanization molding and then combined with metal flange Lapped Joint sets together. It is widely used in fire, chemical, valves and other piping systems, noise from seismic effects, absorption displacement generated during the operation of the pipeline.

Application of flexible rubber coupling

Rubber flexible coupling is a kind of hollow rubber products used to connect steel pipes in mud system. It can also be used for pump connection, valves, and high vibrating pipes, and temperature great vary pipe.

It is a kind of pipe joint with highly flexible, high air tightness, chemical resistance and weather resistance. In oil and gas drilling field, it is widely used to connect tank pipelines, pumps and used between other kinds of steel pipes.

Features of flexible rubber coupling

1) It is with high density internal wall, can withstand high pressure, good elastic reshape performance.
2) Reduce vibration and noise. Light weight design , easy installation and maintenance .
3) The structure can reduce structure borne noise, absorption of vibration.

As the above features, flexible rubber coupling is widely used in mud solids control system, to connect pipes and connect pumps. And flexible rubber coupling is a wearing parts for solids control systems. It needs to be replaced occasionly to aovid aging.

China top solids control manufacturer: GN Solids Control, exported a complete set 1200GPM mud recycling equipments to middle east market for HDD drilling rig.

The system is customized for the customer. To further reduce the total cost of the tank, GN company offered complete equipment, and offer customer tank design drawing free of charge, customer build mud tanks locally. They are happy with the solution and the system used very well now.

Equipment for the 1200GPM mud recycling system:

1) 3 each Shale Shaker GNZS579

2) 1 Mud Cleaner with 3 each 10’’ desander cone and underflow shale shaker model GNZS594 (Desander cones only )

3) Jet mud mixer

4) Agitators

5) Centrifugal pump feeding for the desander cone

6) Mud tanks 1 each. W 3000 mm, H 230omm, L 12000 mm

Customer want tank size is  W 3000 mm, H 2300mm, L 12000 mm with center Partition , the I section for 3 Shale shakers with 2 Agitators,  II section for Mud Cleaner with 2 Agitators and the jet Mud Mixer.

GN standard 200GPM mobile mud system unit is specially designed for borehole drilling and water well drilling in Africa market. The system is compact in footprint and can deal with capacity vary from 100GPM to 200GPM.

Advantage 1# for GN200GPM mobile water well drilling mud system for Africa – Reduce the cost of drilling the water well or borehole

Groundwater is generally a readily available source of water throughout Africa. However, high borehole construction costs are slowing progress on increased access. Higher costs are largely a result of using with specifications that are greater than those required for the vast majority of boreholes needed in Africa. Using high cost machinery and support equipment leads to high borehole costs, which in turn results in fewer boreholes being drilled. The smaller volume of work per drilling rig creates inefficiencies in equipment usage, and results in increased overheads, driving up costs dramatically.

GN 200 GPM water well drilling mud system is matched with a 3 panel double deck shale shaker with mud desilter, it is compact in design and highly cost effective. The water well drilling contractor, they can buy such a mud system for there own water well drilling rig, as well as offer rental service to other drilling contractor.

Advantage 1# for GN200GPM mobile water well drilling mud system for Africa – Compact in design and easy for fast movement

GN200GPM water well drilling mud system can be mounted on a trailer skids for fast movement, especially at jobsite where many water well or borehole should be drilled. After finished drilling a water well, the mud system can be moved fast to another jobsite, no need any lifting device. Users only need to find a trailer head and a man connect the trailer with the trailer head. For futher saving cost, GN Solids Control usually suggest the customer to source the trailer skid locally, GN can offer customized tank dimension to suit for user’s trailer skid.
