DTH Drill Pipes Standard - Down the hole drilling

SINODRILLS Standard DTH Drill Pipes

JK Drilling Product Page

DTH drill rods transmit compressed air, so as to power the hammers to perform drilling works. Sinodrills DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe.The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.

Features

&#; Complete sizes for option, suitable for different types of DTH drilling system;

&#; The rods are made of cold-drawn steel with high manufacturing precision;

&#; Thread joint sturdily linked to the rod via friction welding;

&#; Nitriding process grants the thread joint good hardness, good wearing quality and thus long lifespan.

Applications

Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.

What Distinguishes Geological Drill Pipe From DTH Drill Pipe?

Before engineering blasting, DTH drills are used to bore holes in rocks and fill them with explosives. Electric and internal combustion variants are available.

DTH Drill Pipe:

Purpose:

DTH drill pipes are specifically designed for Down-the-Hole drilling techniques. In DTH drilling, the drill bit is located at the bottom of the drill string, and the hammer is used to provide direct impact for efficient rock penetration.

Design:

DTH drill pipes are typically heavy-duty and sturdy, capable of withstanding the impact forces generated by the DTH hammer. They often have thicker walls and are designed to handle the percussion energy transmitted from the hammer to the drill bit.

Thread Types:

DTH drill pipes may have specific thread types that match the connection requirements of DTH hammers and bits. Common thread types include API threads, REMET threads, or other proprietary designs.

Length and Diameter:

DTH drill pipes come in various lengths and diameters, and the choice depends on the specific drilling application. Longer and larger-diameter pipes may be used for deeper drilling or in challenging geological formations.

Material:

DTH drill pipes are often made from high-strength alloy steels to withstand the harsh conditions and impact forces associated with DTH drilling.

Application:

DTH drill pipes are primarily used in mining, quarrying, construction, and water well drilling where the DTH method is employed for efficient penetration through hard rock formations.

Geological Drill Pipe:

Purpose:

Geological drill pipes are designed for various drilling methods used in geological exploration, environmental monitoring, and core sampling. These methods may include rotary drilling, core drilling, or auger drilling.

Design:

Geological drill pipes are designed to handle the specific demands of the chosen drilling method. For example, core drill pipes must allow for the retrieval of intact rock cores, while auger drill pipes facilitate the removal of soil cuttings.

Thread Types:

Geological drill pipes may have different thread types depending on the drilling rig and the chosen drilling method. Common thread types include API threads, AW/AX/BW/BX/NW/NX/HW/HX/PW/PX threads for core drilling, and various auger connections.

Length and Diameter:

The length and diameter of geological drill pipes vary based on the drilling method and the specific requirements of the geological investigation. Longer pipes are often used in deep drilling projects.

Material:

Geological drill pipes are typically made from materials suitable for the drilling method being used, such as alloy steels for core drilling or durable materials for auger drilling.

Application:

Geological drill pipes are utilized in a wide range of applications, including mineral exploration, environmental site assessments, geological surveys, and soil sampling. They are essential for obtaining subsurface information and rock/core samples.
