and vertical moved swivel joint in well drilling, well cementing,work-over and down hole servicing operation, and also for adjusting the installation mistake between drilling pipe line and stand pipe to avoidshake. Rotary drilling hoses are another of our very popular products we offer, These hoses sometimes referd to as Kelly Hoseare used on the drilling rig and are large bore I.D high pressure flexible rubber steel lines used to connect the swivel to the standpipe. Made of heavy duty rubber and steel cables the Kelly hose flexible piping allows the Kelly and the bit and drill string to be raised and lowered while the drilling fluid is pumped through the drill string. The lowering of the drill string while pumping fluid is crucial to the drilling process. Usually made in diameters of 2″-2-1/2″-3″-3-1/2″ and 4″ i.d’s and in lengths from 30′ ft up to 85′ common length is 75′, 55′ and 65′.

How mud tank works, it is a very easy question, but it contains some good questions behind, so we get all these resolved. First we should know the feature of mud tanks, than the components, how it works in the solids control system, what the main fuction is, last but not least how to clean the mud tank.

Mud Tank Feature

A mud tank is an open-top container, typically made of steel, to store drilling fluid on a drilling rig. They are also called mud pits, because they used to be nothing more than pits dug out of the earth. The mud tank is devided into Square tank and Cone-shaped tank according to the shape of tank bottom. The body of the tank is made of welding the steel plate and section, using the flat cone-shape structure or the corrugated structure.

Components of Mud Tank

The mud tank surface and the passage are made of the slipping resistant steel plate and linearity netted steel plate which is produced by the professional factory, the mud tanks are made of the side steel pipe, all of the structure can be folded without barrier and pegged reliably. The surface of tank is equipped with water pipeline for cleaning the surface and equipment on the mud tank, we use soaked zinc processing for the netted steel plate. The ladder is made of Continue reading →

Which one is the core facility of drilling fluids system, we all may think about shale shaker, mud cleaner, vacuum degasser, or decanting centrifuge. And I should also say no. Then I will tell you the answer, the VALVE, this is one facility which control all the equipment to make them work or not. Drilling Fluid Valve must met the demand for heavy duty replaceable seats -with that and only with that we changed everything. Production expectations were raised. Drilling fluid systems functioned more efficiently and effectively.

Good news from GN Solids Control

vacuum degassing systems for the oilfield industry

Vacuum degasser is one important part but not a phase of solids control, it is used to separate the gas and drilling fluids for safe and enviorment friendly. It is always installed after the shale shaker, and before the desander and desilter (or mud cleaner).

vacuum degasser manufacturers and vacuum degasser suppliers

Vacuum degasser is produced by solids control equipment manufacturers, take GN solids control for example.
Also there are a lot of manufacuters supply the vacuum degasser, here is one list of the manufacuturers

The desander and desilter are important parts of solids control system, and the hydrocyclone cones is the key component. Here is the detailed introduction of the cones design, the use and ability of desander desilter cones, and then I introduce you the manufacturers of  desander cone and desilter cones.

Desander desilter cones design

The desander cone and desilter cones all are also referred as hydrocyclone cones, cones are basically separate the solids from drilling fluids. The separation process is carried out by employing centrifugal forces. The Cones are made of high durameter polyurethane with optional steel inserts, which ensure consistent productivity.

Centrifugal pump with mechanical seal some are required by GN Solids Control Clients for drilling mud System.As a manufacturer for mechanical seal centrifugal pump we give explanation info. as below.

Centrifugal Pump

A centrifugal pump is a roto dynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads.

Centrifugal Pump With Mecheanical Seal

In some situations, packing material is not adequate for sealing a centrifugal pumps shaft. One common alternative method for sealing the shaft is with mechanical seals. Mechanical seals consist of two basic parts, a rotating element attached to the pump shaft and a stationary element attached to the pump casing. Each of these elements has a highly polished sealing surface. The polished faces of the rotating and stationary elements come into contact with each other to form a seal that prevents leakage along the shaft.

The most effective method of preventing the leakage of the drilling  fluids from the centrifugal pump to the external surroundings is using the mechanical seals. The mechanical seals Continue reading →

GN complete line machineries can be used for liquid and solids separation.

Below,you’ll see a machineries table which used For GN240 Liquid Solids Separation.

Liquid Solids Separation Process
1. The 150YZ250-40B Slurry Pump Feed GNZS150-3 Shale Shaker from Slurry Pit.

2. In the first phase the Liquid and Solids passes over GNZS150-3 Shale shakers with 40mesh Screens to remove debris and larger particles. The debris can include: grass, roots, leaves, cans, plastic, rags and bottles. Solids Size≥0.41mm will be removed from the liquid

Liquid Solids Separation Machinery

3. The Liquid with solids size≤0.41mm, with the above debris removed drops into an isolated section of the tank(Compartment 1) where it is picked up by a 150YZ250-40A Slurry Pump.

4. This 150YZ250-40A Slurry Pump. moves the slurry to the second phase, feed liquids with solids to ZQJ250x3 Desander(10” Cones).

5. Here the liquids with solids is pumped through the de-sanding Hydro-cyclones, which removes the solids above the 75 micron size.

6. The overflow from these hydro-cyclones drops into a second isolated tank section(Compartment 2), while the underflow is discharged from the trough of the ZQJ250x3 Desander. Continue reading →
