A mud tank is an open-top container, typically made of square steel tube and steel plate, to store drilling fluids on a drilling rig. They are also called mud pits, because they used to be nothing more than pits dug out of the earth. A mud tank is a large storage container used to hold reserves of drilling fluids, also known as drilling mud, for a drill rig. Drilling fluids is used to reduce friction on drill components to allow them to work harder and faster with less risk of breaking down. Numerous companies manufacture and refurbish mud tanks of various shapes and sizes for industrial use, and contractors who specialize in mud cleaning tanks and other drilling equipment are also available. The cost for tanks and associated services varies widely, especially when customer designs are involved.

Mud tank design for solids control system is very important. The surface pits that comprise the active circulating systems should be designed to contain enough usable mud to maintain mud properties and to fill the hole during a wet trip at the rig’s maximum rated depth. Usable mud is defined as the mud volume which can be pumped before suction is lost.

As a mud carrier, mud tank is an indispensable part of mud circulation system and it can complete weighting, mixing, solid/liquid separating, degassing and other processes. Mud tank carries the mud circulating between well head and mud pump. The solid particles in mud are separated stage by stage through relevant solids control equipment on mud tanks as to make the fluid meet drilling requirements after mixing and weighting system.
 

Mud Tank Structure

Mud tanks are divided into square tanks and cone-shaped tanks according to the shape difference of the tank bottom. The body of the tank is made by welding the steel plate according to national standard and section, using the smooth cone-shape structure or the corrugated structure. The mud tank surface and passages are made of slip resistant steel plate and expanded steel plate. 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 the tank is equipped with a water pipeline for cleaning the surface and equipment on the tank, it uses soaked zinc processing for the expanded steel plate. The ladder is made of channel steel to support the body, the foot board is made of expanded steel plate. The two-sided guard rail are installed with the safe suspension hook. The mud tank is designed as the standard shanty to prevent the sand and the rain. The pipeline is installed in the tank to preserve the warm air and heat.

KOSUN Mud Tank adopts centralized electric control; heating and heat preservation system is applied for tank body in polar regions. KOSUN Mud Tank has the advantages of: ensuring no mud loss, reducing environmental pollution, lowering labor intensity and satisfying drilling requirements timely through mud mixing. KOSUN can also design and manufacture mud tanks according to customers' specific requirements

Apart from mud tank, KOSUN can manufacture water tank and diesel tank in different shapes for many industries. As a professional manufacturer in solids control equipment and solids control system, KOSUN manufacture products like shale shaker, mud gun, desander, desilter, centrifugal pump, mud cleaner, vacuum degasser, mud agitator, decanter centrifuge.
