N850 Od 5 1/2 Inch Non-Magnetic Heavy Weight Drill Pipe

Product Description

N850 non-magnetic heavy weight drill pipe is a drilling tool with excellent performance and easy operation. With proper operation and maintenance, it can give full play to its performance advantages and meet the drilling requirements under various complex geological conditions.

Basic Info.

Classification of Heavy Weight Drill Pipe

1.Integral heavy drill pipe

It is a kind of drilling tool made of integral casting or forging process, with extremely high strength and rigidity. It is suitable for deep hole drilling, complex formation drilling, and drilling operations requiring high torque transmission. The surface of the integral heavy duty drill pipe is specially treated to provide excellent wear and corrosion resistance.

2.Spiral heavy drill pipe

Suitable for drilling in soft and medium hardness formations. The spiral groove design can increase the friction between the drill pipe and the hole wall and improve the drilling efficiency. At the same time, this kind of drill pipe also has good strength and rigidity, can withstand large drilling pressure and torque.

3.Weldedheavy drill pipe

A welding process is used to connect multiple drill pipe segments. It is suitable for long distance drilling, complex formation drilling, and drilling operations requiring high flexibility. It has high strength, high rigidity and good corrosion resistance, which can meet the needs of drilling in various complex geological conditions.

N850 Non-magnetic Pipe | Main Features And Operating Instructions

1. High strength: N850 non-magnetic pipecan withstand large drilling pressure and torque, to ensure the smooth progress of drilling operations.
2. Non-magnetic: It avoids the influence of magnetic field on the drilling results, and is suitable for the drilling environment where magnetic interference needs to be avoided.
3. Corrosion resistance: Alloy material has good corrosion resistance, extending the service life of drill pipe.
4. Good connectivity: Reliable connection between drill pipes ensures stability and safety during drilling.

Operating Instructions

1.Drill pipe connection:

When connecting the drill pipe with the drill bit and drill tool, ensure that the connection part is clean and free of impurities.

Use special connection tools or equipment to connect according to the specified torque to ensure that the connection is firm and reliable.

2.Drilling operation:

Before starting the rig, ensure that the drill pipe is properly installed and secured.

Gradually increase the pressure and speed of the rig to avoid damage to the drill pipe caused by sudden increase in load.

During the drilling process, we should pay close attention to the working state of the drill pipe, and stop the machine for inspection in time if there is any abnormality.

3.Post-drilling treatment:

After drilling, the drill pipe should be removed from the drill hole, and cleaned and maintained.

Check the drill pipe and its connecting parts for wear and tear, and replace or repair them if necessary.

4.Safety precautions:

In the process of drilling, safety operation rules should be strictly observed to ensure the safety of personnel and equipment.

The heavy weight drill pipe should avoid collision with hard objects during use, so as not to damage the surface or internal structure of the drill pipe.
