The unique design of the drill bit directs the air over the drill bit surface reducing the air leakage into the ground. Atlas Copco Secoroc have been continuously improving the casing advancement system.

It is suitable to use for straight piling or well drilling that requires the high performance needed for drilling large and deep holes. The unique design of the pilot bit directs the air over the drill bit surface, reducing air leakage into the ground. A symmetrical ring bit. Symmetrix and Elemex Contact us. Aircontrol and minimized overdrilling is essential to reduce these risks. The Symmetrix system is a patented system comprised of an ingeniously simple concentric method of drilling through overburden with casing.

Geothermal well drilling Geothermal heating of houses is increasingly popular due to both economical advantages as well as environmental concerns. Each bit, made from quality tungsten carbide steel, is precision machined to produce a perfect body.

Symmetrix and Elemex

Discover Industry solutions Products Services. Accessories for Casing advancement systems A range of accessories are available for the Odex, Symmetrix and Elemex systems, such as smymetrix tools, wrenches and welding fixtures. The Elemex system not only minimizes air escape, but also prolongs drill bit service life and, in some cases, actually drills faster than any other system available. Our engineers responded by incorporating the Quantum Leap air cycle into the RC hammer, creating a high frequency hammer with world class symmetrrix and reliability.

When drilling in so-called overburden, the conditions are often challenging with risk for collapsing walls, hole deviations, and failure to reach design depth or bedrock.

The choice of solution depends on several factors, including ground conditions and application. Water well drilling Water well drilling is common in urban, developed areas where the well must be drilled quickly with minimum impact on the symmdtrix. The choice of solution depends on several factors, including ground conditions and application. Click on casing size tab for specs, then roll pointer over or click on the table to enlarge.

Geo- thrmal Well Drlg. A steel casing is installed in an umbrella pattern around the excavation line, forming a protective arch under which the tunnel can advance. Symmetrix – Productivity and Precision Symmetrix is a versatile solution symmstrix overburden drilling where ground conditions are difficult, time is limited, and precision is crucial. Elemex – For Improved Air Control The Elemex casing advancement system is the preferred system for minimizing the risk of settlement symmrtrix surrounding structures.

When drilling in so-called overburden, the conditions are often challenging with risk for collapsing walls, hole deviations, and failure to reach design depth or bedrock. The content of the web page is organized by casing outer diameter. symmrtrix

Casing Advancement Systems (Symmetrix / Elemex)

Secoroc DTH hammers are available in holes sizes from 3,5 to 48 inches in diameter and up to 72 inches with the Secoroc Cluster drills.

The system symmeteix more quickly and accurately than any other method available today. The maximum wall thickness is defined for all systems. Geothermal well drilling Geothermal heating of houses is increasingly popular due to both economical advantages as well as environmental concerns.

The directed air flushing enables the driller to be in full clpco of the drilling process.

Whether there are shmmetrix boulders, inclined competent layers or hard rock bed, Symmetrix continues to drill until the required depth is reached. Atlas Copco offers a Permanent Ring bit system for DTH drilling — Symmetrix, an all-round overburden drilling system for holes of any depth or size.

The designation code makes it easy to identify the key parameters of the system. The following are examples of the most common applications. Elemex is not only a safe choice where settlement of neighbouring buildings can be a risk with other methods.

Foundation work Stringent demands on productivity, high drilling accuracy, and the ability to drill inclined piles for foundation work make casing advancement systems increasingly popular for both end bearing and friction piles. Odex Under-Reaming Systems for Tophammer. Foundation work Stringent demands on productivity, high drilling accuracy, and the ability to drill inclined piles for foundation work make casing advancement systems increasingly popular for both end bearing and friction piles.

This page describes a complete system solution and different application scenarios, allowing you to select the atlaa equipment from the extensive product portfolio. We even offer environmentally friendly water-lubricated hammers and the reverse circulating RC hammers aimed at Green Field exploration.

Odex Under-reaming systems for DTH Under reaming systems are most economical solutions for casing drilling in normal ground conditions.

Casing Advancement Systems

Manufactured in-house, each bit is finally fitted with the required shape and sized buttons. This is an extra advantage when sensitive ground is encountered. Retrievable Casing Retrievable casing is used when the casing is only needed during the drilling process, that is when it is used to keep the hole open during drilling and not used as support in the finished altas. When changing the pilot bits you only need one ring bit set for both pilot bits, and you will save time as well as money.

Whether used in ground with big boulders, inclined competent layers, or hard bedrock Symmetrix drills until the required depth is reached. For these components two different setups are offered by Atlas Copco. This enables contractors to perform their work faster copci higher quality and reduced risk.

Odex systems has become the standard among drilling contractors for casing in water wells, symmetfix wells and for shallow micropiling work.

For setup one all three above mentioned components should be ordered. Anchoring Tieback anchors, or ground anchors, are common all over the world. Applications Casing advancement systems can be used in a wide range of applications where you need to drill in difficult ground conditions. News and stories Customer stories Buy spare parts. This enables contractors to perform their work faster with higher quality and reduced risk.
