Pipeline Design for Installation by Horizontal Directional Drilling -. v. Hinueber, Edgar (iMAR Navigation) (2006). Its convenient methodology for selecting an appropriate pipe strength (wall-thickness), based on the project characteristics, has led to its increasing popularity and widespread usage within industry. Drilling mud is used to cool the cutter and transmitter electronics, to flush excavated soil from the borehole and to lubricate the borehole. ?5Hb0CB$ 17C``!Dc@ q Welcome customers to visit the factory, or third party factory inspection is acceptable. Unnecessarily large curvatures (sharp bends) also contribute to bending stresses in the HDPE pipe, but generally are not significant for such a flexible product. The tensile load on the pipe during installation must be calculated to establish whether it exceeds the maximum allowable load. This can be changed at any time via the Cookies link at the bottom of the page. That is, the soil is being cut and or removed under the influence of high pressure fluid. This phenomenon is referred to as the capstan effect, as it is the principle of the capstan winch, as illustrated in. Compared with traditional trenching and buried pipes, it has better technical, environmental protection and economical efficiency, and is suitable for crossing streets, highways, railways, buildings, and rivers, especially in downtown areas, historic sites, green belts, where excavation is impossible or unsuitable areas. ;0CKh6sKjrmlq9vwiJ%)m5]UWd It is used instead of other techniques to provide less traffic disruption, lower cost, deeper and/or longer installation, no access pit, shorter completion times, directional capabilities, and environmental safety.

The drilling fluid is typically a suspension of a bentonite clay and polymers. The ASTM document provides overall guidelines for a maxi-HDD operation, addressing preliminary site investigation; safety and environmental considerations, regulations and damage prevention; bore path layout and design; implementation; and inspection and site cleanup. Software tools are based on the ASTM F1962 document and model. H0+X u7A@>&F Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. Horizontal drilling, one type of directional drilling, is a method that is used to install pipes, conduits and cables underground in a long shallow arc. International, Inc., 2015, pg. Joints in traditional piping materials are the biggest source of leakage. Chapter 12 Horizontal Directional Drilling 416 borehole on pullback. 0000029412 00000 n Because the operator of the drilling rig might not notice a momentarily excessive pulling force, a load link inserted between the swivel and the PE100 pipe to record pulling load can be used to record the maximum axial load exerted on the pipe. High-density polyethylene (HDPE) conduit is the preferred material to house and protect electrical power and telecommunications cables within. It was reissued in 2005 and 2011, and previously reinstated in 2020. The mud motor is powered by the drilling mud pumped through the drilling rods. The MGS, even without the use of the wire grid, has been accurate to over 2km with an accuracy of 2% at depth. They are monitored throughout the process to make sure the bore stays open, pumps are not overworked, and uid circulation throughout the borehole is maintained.

Directional drilling is the drilling of non vertical wells. endstream endobj 749 0 obj <>stream Generally, the term Horizontal Directional Drilling (HDD) is intended to describe large/maxi sized drilling rigs, large diameter bores, and crossing lengths in terms of thousands of feet. For diameters greater than 180mm, the pipe should be made into a continuous string by butt fusion of straight lengths, and sufficient space must be available on site to make up and store the string ready for installation. At no time during welding or installation must the pipe be allowed to drag on the ground and it must therefore be supported on rollers, though it should be stored directly on the ground to avoid indentations from supporting rollers or timbers if there is to be a delay in installation. 0000016763 00000 n The number of construction personnel is relatively small, and at least 10-20 people are required for manual excavation, while only 7 people are used for pipeline directional drilling technology. The pipe bursting method is in full compliance with all federal regulations and guidelines. This is achieved by pumping drilling fluid (mud) down the inside of the drill rods, which flushes the drilled material back out of the bore. HDPE is the safest and most efficient option for sewer pipe replacement. Calculator allows, users are recommended to review PPI TR-46 and/or ASTM The pilot bore is created using a drilling head, which in its simplest form has a slanted face, and this is pushed and rotated by long high tensile flexible drill rods. The theoretical model used to develop the formulae for estimating the peak required tension (Section 8) assumes that the local frictional drag forces on the pipe are proportional to the local normal bearing forces applied at the pipe surface. Horizontal directional drilling (HDD) is a trenchless construction method used to install pipes underground without disturbing the ground surface. He can be reached at lslavin@ieee.org. Example of Capstan Effect (Courtesy of Outside Plant Consulting Services, Inc.). UI. HDD, also known as directional boring, was developed in the early 1960s and was first used by the oil and gas industry on large-diameter, cross-country pipeline transmission line installations. The recent (2022) edition of ASTM F1962 has revised the relevant physical characteristics of the PE materials, providing the physical properties for the most recent high density polyethylene (HDPE) material, PE4710. Soils containing high percentage of gravel and cobbles are best avoided unless the contractor is especially experienced in the conditions. illustrates the operation in a city or urban application. Furthermore, any construction procedure must address basic safety rules, avoid damage to existing facilities, adhere to applicable government regulations, and consider environmental issues. Wire-line locating system The wire-line system is a magnetic guidance system. must be consistent with the steering capability of the maxi-HDD equipment, and the bending capability of the drill rods. The full range of PE100 diameters from the smallest to a maximum diameter of around 1200mm can be installed by HDD, though the required installation length may limit the use of PE100 pipe even if a heavy wall pipe is used. [5], Tooling, as in the mechanical apparatus that are installed to the drill string to conduct operations, are available in a wide number of different shapes and sizes. [citation needed], The technique has extensive use in urban areas for developing subsurface utilities as it helps in avoiding extensive open cut trenches.

Most soil and rock types can be drilled with the appropriate tooling and processes. Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of HDPE (PE4710) Pipe in Municipal Applications. Directional boring tooling includes the suite of drill bits or drill heads used during pilot hole operations, reamers and hole-openers used for hole enlargement, and swab tools which are used for hole conditioning and pullback. At the surface a receiver (usually a hand-held. Toggle navigation. Directional boring and HDD are similar in some respects to directional drilling associated with the oil industry, however, an equal comparison cannot be drawn as the procedures serve markedly different functions. CANTEX's CAN>LOC and CAN>GRIP systems offer many benefits over HDPE, which is the conduit most used for HDD applications. This picture shows a slant face drilling bit, also fitted with carbide tipped teeth that enable it to penetrate hard ground.

Where cables and other utilities are identified in close proximity to the proposed alignment they should be exposed so that progress of the drilling can be monitored and stopped if required. 0000002438 00000 n [citation needed], The process starts with the receiving hole and entrance pits. Register here to perform horizontal directional drilling analysis using our HDD Calculator. HDPE pipes are ideal for pulling through long, underground holes as they are flexible, robust, and resistant to almost all aggressive elements. endstream endobj startxref MAB-08 (2022) - MAB Guidelines for Fusing HDPE Pipe in Cold and Inclement Weather, Horizontal Directional Drilling Estimating Pipe Pulling Tensions, Dr. Lawrence M. Slavin, Aug 2022. Horizontal directional drilling (HDD) is a cost-effective method for installing polyethylene (PE) gas pipe in urban and congested suburban areas, and many gas utilities have come to appreciate its advantages. Directional boring can be utilized to cross any number of surface obstacles including roadways, railroads, wetlands, and water bodies of varying sizes/depths. [citation needed], For smaller bores, proportionally smaller and more portable equipment is available. User Inputs. One of the most significant contributions of ASTM F1962 is the provision of a rational, analytical method for selecting the pipe strength based on estimated installation loads on the PE pipe.

Used in the oil industry to cross the river oil pipeline, Used in power system for the telecommunications cable conduit, Used in the construction of municipal drainage pipelines, Water and gas pipeline network transformation. Drill bit location for smaller and shallow installations is typically transmitted by a battery powered sonde, located just behind the bit, the signals being picked up by a receiver operated at the surface. The output of the Calculator can be used to assist the User in Advantages of the High Density Polyethylene Trenchless Pipes For Horizontal Directional Drilling The biggest advantage of HDPE HDPE trenchless pipes for HDD besides its long-life expectancy, is its heat-fused joints, which make the pipe a single homogenous pipeline. Horizontal directional drilling shall consist of the drilling of a small diameter pilot hole from one end of the alignment to the other, followed by enlarging the hole diameter for the pipeline insertion. Thus, ASTM F1962 provides a means of determining project feasibility, as well as initial design information. The ASTM document provides overall guidelines for a maxi-HDD operation, addressing preliminary site investigation; safety and environmental considerations, regulations and damage prevention; bore path layout and design; implementation; and inspection and site cleanup. This arc follows a preset bore path using a surface drilling rig. Once the bore has been completed and reamed to the required diameter, the PE100 pipe is prepared for pull-back by attaching the end to a pulling head, swivel, reamer and drill rods at the drill exit point. This arc follows a preset bore path using a surface drilling rig. The drill rig and auxiliary equipment located on the pipe exit side are relatively large, and require water access, storage, and mixing and pumping facilities. Horizontal directional drilling is often used where open cut installations are not feasible, such as road and river crossings. It is designed to be maintenance free as there is no need for man-entry maintenance. The size, complexity and need for additional support equipment increases generally as the pipe diameter and length increase. We have a full line of products to suit your HDD needs. While the document provides useful information for evaluating the potential for collapse under lateral pressures, either during of following installation, the most widely used portion of ASTM F1962 are the formulae for estimating the pulling tensions corresponding to the leading end of the pipe reaching point A, B, C and D. These formulae account for the frictional drag acting on the pipe along the surface of the borehole, primarily due to the high buoyant weight of the HDPE pipe, within the relatively dense drilling fluid, especially for vacant pipe. This method applies tension to the PE100 pipe during installation. hb```i|@Y8Ldhp`iPpgpg#LK:pt2&55/a?aOJ3h13(81dU 8vk& 47kQK\ V'Pj{r e7*fp7D ~aKr+dXi-@%q[cqSxj'VJmxj U[z'. Fluid can be pumped through the drill rods and out through jets in the bit to assist the operation.

Horizontal Directional Drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribe. Pressure capability is dependent upon pipe SDR and is not a function of the method. Physical properties of the PE material(s) are provided in the appendices, which allow determination of an appropriate wall thickness for the pipe, depending on its diameter and estimated peak pulling force (or tendency to collapse). The Conduit Design Calculator is a software tool that aids in determining the most appropriate wall thickness of high-density polyethylene (HDPE) conduit installed via horizontal directional drilling (HDD) techniques. While considered convenient and practical to apply by experienced engineers for a maxi-HDD operation, the overall ASTM International F1962 procedure and guidelines represent a relatively extensive, tedious process, when considering smaller, lower cost operations associated with typical mini-HDD applications. q$mO9-Dbqbv(ln!1*YDt=.7 Reliable communications must be in place between the pipe entry location and the drilling rig operator, so the rig can be stopped immediately if required.

On inaccessible projects such as river crossings or where the bore is at significant depth and where a surface receiver cannot be used, the drilling head location information is typically sent from the drill bit by a wireline system, via a wire running along the inside of the drill rods. Typical Entry Site Layout. All three systems have their own merits, and a particular system is chosen depending upon the site requirements. FIGURE 2 illustrates a typical geometry for a maxi-HDD operation, in this case corresponding to a river crossing. With a magnetic guidance system (MGS), the tool reads inclination and azimuth. HDPE is a polyethylene thermoplastic made from petroleum. However, they are sufficiently general to consider the possible implementation of anti-buoyancy measures to reduce these otherwise high frictional forces. If the calculation shows that the maximum permissible load may be exceeded then it may be necessary to increase the capacity of the PE100 pipe by increasing its thickness.
