MUD Manifold

The drilling fluid manifold consists of 4″-5000PSI & 2″-5000PSI Demco DM gate valve, high-pressure spherical union, high-pressure core union, tee, high-pressure hose, elbow, pressure gauge, and pup joint etc.

Ground valve-group adopts goose type tee with compact structure, little fluid resistance and large power effectuality Adaptor spool adopted on rigid valve-group can be directly used as single pipe on site.

High-pressure union, made of high-strength alloy steel and heat-treated, can create quick strip. As for being manufactured with special machining tool, it can create seal under fine sphere and core matched with sealing ring.

The gate and valve seat of 2″-5000PSI DM gate valve are welded with carbide against erosion and corrosion, so that it can enlarge the working life, little operating torque.

Elbow, adaptor, tee and cross are made of high strength alloy steel, with suited wall thickness and fine heat treatment, so it can meet the requirement on strength and corrosion.

The part required at high precision, should be machined with special technique to ensure the manufacture quality, and the pressed part should be hydrostatic tested on strength and sealing property to ensure the ex-plant quality.

Installation

1. First to clean up each sealing face and sealing groove of union and coat it with grease and get rid of dirt from the pipeline.

2. Check whether each jointer is fastened or not.

3. As for shipping, to disassemble into parts, clean up pipes, coat the connections with grease and then, to be wrapped well up to avoid foreigner entrance and sealing surface damage.

Operation note

1. Regularly inject mud gate valve with grease to maintain the gate valve;

2. Regularly check whether all connecting position and

fixing bolts are loose;

3. If leak around sealing position, the seal should be replaced immediately;

4. Keep the outer surface of the manifold clean and paint it against rust regularly.

DM GATE VALVE

 (Interchangeable with Demco® Model DM Gate Valve)

The DM Gate Valve, are solid gate, rising stem, gate valves with resilient seals. They are purpose made for mud, cement, fracturing and water service and are easy to operate and simple to maintain.

The DM Gate Valve, with superior design features precision workmanship and a proven principle are engineered to meet the harsh drilling requirements in today’s oilfield.
