The horizontal directional drilling (HDD) technology and pump are used for water, oil, and gas piping, in underground infrastructure. The HDD technique can be directed through a curvature or conducted from the surface level as well.
The Horizontal Directional Drilling Process
The three phases of HDD drilling include:
Pilot Drilling- During this drilling procedure, a drilling machine pushes the drill bit through the surface of the earth. The hole at this point of time may be up to 1.5 times larger than the drill bit’s size. Bits of varying diameters are used for the process and are available with variations in between 50 to 250 mm.
Reaming- A fly-cutter replaces the drill bit once drilling is successfully accomplished. The drill hole gets enlarged as the fly cutter is pulled back. Hence reaming creates the drill hole of the desired diameter.
Pipe Pulling- Once the reaming operation gives a sufficient diameter size for the hole; a product pipe and the final ream are used.
As we can see the HDD technology and technique is a trenchless and minimal impact technique. It is successfully accomplished by the heavy-duty and rugged horizontal directional drilling equipment that can withstand the circumstantial demands and roughest of terrains and environment. HDD may be used more in cases and regions where excavation or conventional trenching is not possible. The technique is also useful in areas where the surface cannot be disturbed heavily.
The Equipment Used for HDD Technique
Some of the horizontal directional drilling equipment determinants include runs, length, pipe diameter, and terrain and ground conditions. Drills with 600 tons of push-back strength may be used when larger holes are required. Multiple high-quality pumps, excavators, and hoses are some of the equipment used in the HDD process, and supply of the drilling fluid to the drill site is an important part of the process.
The best drilling well pumps manufacturers in Houston offer the quintuplex drilling pumps that can ferry the largest fluid amounts easily. These high-efficiency pumps also possess high-efficiency additional cylinders to null the pulsation variances. Good quality HDD equipment ensures that your processes are accurate and up to the standards. Hence buying them from reputed drilling pump manufacturer company that has decades of experience should be one of your topmost priorities.
