Rotary Drilling Hose: A Sharp Tool in Analyzing Drilling Engineering

 I. Introduction

As an indispensable and important equipment in drilling engineering, rotary drilling hose undertakes multiple functions such as conveying flushing fluid, transmitting power, and enduring bending and torsion. This article will make an in-depth analysis from the aspects of hose usage, specifications, hose characteristics and precautions, etc., to give you a comprehensive understanding of the charm of rotary drilling hoses.

2. Use of hose

Rotary drilling hoses are widely used in oil drilling, groundwater wells and geological exploration and other fields. As an important transmission channel connecting the drilling platform and drilling tools, it can not only transport flushing fluid and drilling fluid, but also transmit the power of rotating equipment, providing solid support for the success of drilling engineering.

3. Main specifications

The specifications of rotary drilling hoses are generally classified according to their inner and outer diameters, working pressure, maximum bending radius and other indicators. Typically, the hose ID ranges from 4 inches to 6 inches, and the outside diameter ranges from about 5.5 inches to 9.5 inches, with working pressures up to 10,000 psi. Depending on the working environment, the maximum bending radius of the hose is also different, generally between 5 meters and 10 meters.

4, the characteristics of the hose

1. Excellent pressure resistance
Rotary drilling hoses are made of high-strength synthetic materials with excellent pressure resistance and can withstand working pressures up to thousands of Bar. Under severe working conditions, the hose can stably transport flushing fluid to ensure the continuous progress of the drilling project.
2. Flexible and anti-fatigue ability
Hoses are subject to bending and torsion, but rotary drilling hoses are specially processed to improve their flexibility and fatigue resistance. Even under frequent stress, the hose maintains its stability and durability.
3. Excellent chemical corrosion resistance
During drilling, chemicals such as flushing fluids can cause corrosion to hose materials. However, the rotary drilling hose is made of special material and production process, which makes it have excellent chemical corrosion resistance. This means that the hose can maintain its excellent performance during long-term use, reducing the frequency of maintenance and replacement.

5. Precautions for use

1. Temperature control
The operating temperature of the rotary drilling hose should be within the specified range. Excessive temperature will affect the physical properties of the hose and even cause the hose to be damaged. Therefore, attention should be paid to temperature control during use, and necessary cooling measures should be taken.
2. Periodic inspection
To ensure the integrity and performance of the hose, regularly inspect the hose surface for any damage, especially the hose end connections and bend areas. Finding problems in time can prevent potential accident risks.
3. Correct operation
When using rotary drilling hose, follow proper operating procedures to ensure that the hose is not twisted or folded excessively. At the same time, avoid contact between the hose and other sharp objects to avoid scratching the surface of the hose.

6. Summary

As an indispensable equipment in drilling engineering, rotary drilling hose has excellent pressure resistance, flexible fatigue resistance and excellent chemical corrosion resistance. When in use, attention should be paid to temperature control, regular inspection and correct operation. I believe that through the introduction of this article, you have a more comprehensive understanding of the rotary drilling hose, and it will continue to play an important role in helping the smooth progress of the drilling project.
