Simple information on mud gun

The mud gun also can be called mud mixing gun. As we know it is usually used along with mud agitator as mixers for oil rig.

The mud gun is consisted by main construction by steel pipe and flange, the valves (including high pressure or normal pressure), and the rotary parts.

The mud gun is simple in design or structure. Usually all turning takes place on double rows of steel balls in flame hardened races. There is nothing to tighten or adjust. Flow is unrestricted and pressure drop is minimum.

Mud gun types in GN

I. Divided by pressure. There will be high pressure and normal pressure

II. Divided by rotary type. There will be with manual rotary or fixed type

III. Divided by diameter. There will be 2″ (NJQ50) and 3″ (NJQ80)

IV. Divided by nozzle number. There will be single one and triple one, etc.

Mud gun on oil rig

Mud gun in solids control system on oil rig. As we said, it will be used together with mud mixers. And the mud resources to mud gun is given by mud pump in oil rig. The mud gun can mix or spray mud to dead angles. This will make mud more even and better effect than mud agitator.

Moreover, the mud guns on oil rig also have normal pressure and high pressure. This is according to client’s demand. Different oil rig will request relative mud gun.

And the different oil rig have different mud system, such as difference on treating capacity, difference on mud tank capacity, difference on mud properties, ect. Then mud guns should hold relative height, etc.

 

NJQ Mud gun common parameters

NJQ50 holds 2” diameter, and 2” valve can be butterfly or gate valve, then the connector size should be also 2”. The pressure can be normal pressure(0.6Mpa) or high pressure(1.6Mpa),the nozzle number will be customized as 3 or 1. And there will be rotation angle by manual rotation.

There is another common type NJQ80. Almost same with above one just the diameter, valve, connector, etc. dimension will be 3”.

On oil rig drilling mud system the mud gun is usually fixed in active tank. However, we can design it subject to actual circumstance and situation or requirements by clients.
