For the larger diameters, the equipment is large, and requires support equipment such as generators and hydraulic power units. This material is significantly tougher than older, previous polyethylene (PE) products, facilitating successful completion of more complicated, difficult maxi-HDD projects. Now Available: ASTM Guide for Use of Maxi-HDD Placing HDPE Pipe Under Obstacles. These pipelines can not only provide a design life of 100 years, but also provide solutions to major industry challenges such as corrosion and high leakage rates. Horizontal directional drilling is often used where open cut installations are not feasible, such as road and river crossings. 3), PR-277-144507-Z01 Installation of Pipelines by Horizontal Directional Drilling Engineering Design Guide (Arlington, VA: Pipeline Research Council Experience: Actively engaged in horizontal directional drilling for minimum of 3 years. These plastic pipes offer a new generation of leak-proof, maintenance-free, and energy-efficient pipeline systems that are chemical- and abrasion-resistant and therefore excellent for use in the lining and relining of pipelines, slurry applications, water reticulation, sewer and stormwater systems, the mining industry, and in dolomite areas. was originally approved in 1999, following development within the ASTMs F17.67 Trenchless Technology Subcommittee. The term "directional boring" or "bore" is generally reserved for mini/small sized drilling rigs, small diameter bores, and crossing lengths in terms of hundreds of feet. Horizontal Directional Drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribe. To determine HDPE pipe performance during and following construction, linear displacement transducers, strain gauges, and a temperature probe . v. Hinueber, Edgar (iMAR Navigation) (2006). Recycled water pipeline completed in Encinitas, Calif. He can be reached at lslavin@ieee.org. The bore is steered to create an initial hole at the required line and grade. Directional boring can be utilized to cross any number of surface obstacles including roadways, railroads, wetlands, and water bodies of varying sizes/depths. water tanks, spoil containers, etc.) Whilst the rods are simultaneously rotated and pushed, the bore will, provided it is not deflected by some obstruction, proceed in a straight line, but if it is simply pushed without rotation it will deflect in the opposite direction to the slant face on the drilling head. and Material (type of HDPE). It is using a simple flat blade slant face head for drilling in clay, the excavation being typically sized for man entry piecing up. The staging of larger diameter and longer pipelines may require the use of pipe rollers and other facilities to ensure the pipe is not damaged during pull-back. To obtain pressure in psi, multiply bar by 14.5 (1 bar 14.5 psi). Figure 2. It is a mixture of water and, usually, bentonite or polymer continuously pumped to the cutting head or drill bit to facilitate the removal of cuttings, stabilize the bore hole, cool the cutting head, and lubricate the passage of the product pipe. endstream endobj 749 0 obj <>stream 0000017112 00000 n HDPE water pressure pipes can be connected by a process called butt fusion, where the ends of the pipes are heated and joined together. This page was last edited on 12 December 2022, at 19:58. This will require a check of ID and OD to ensure that flow capacity and external clearances are still adequate. 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. 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 180mm the maximum length on a coil is generally 100 metres, and smaller diameters can be longer. Thus, ASTM F1962 provides a means of determining project feasibility, as well as initial design information. The driller increases the diameter according to the outer diameter of the conduit and to achieve optimal production. Successive reamers are then pulled back to enlarge the bore diameter to the desired size. Why choose PE compounds for pressure pipe ? Including River Crossings. Drilling fluid holds the cuttings in suspension to prevent them from clogging the bore. This arc follows a preset bore path using a surface drilling rig. The Calculator uses input such as directional changes in the bore path, and other project variables, to determine the Calculated Tensile Load on the selected HDPE conduit, as compared to the . The intermediate horizontal segment, L, , may be of zero length. hbbd``b`$mA,k D\ 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). %%EOF 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. For larger diameter pipes, which are supplied in straight sections, these sections should normally be fused together to form a single continuous length of pipe prior to commencing the pull-in operation. [3], The process is suitable for a variety of soil conditions including clay, silt, sand, and rock. hTYO0OG >rKR(PQ9Fg&% 29), PR-277-144507-Z01 Installation of Pipelines by Horizontal Directional Drilling Engineering Design Guide (Arlington, VA: Pipeline Research Council This material is significantly tougher than older, previously used PE products, facilitating successful completion of more complicated, difficult maxi-HDD projects. Allowable pulling loads are based on a minimum tensile yield strength of 3,500 pounds per square inch (psi), with a significant reduction to limit non-recoverable viscoelastic deformation, as well as account for the effective cumulative load duration on the pipe (assumed to be 12 hours), resulting in a safe pull stress of 1,330 psi. %PDF-1.5 % Safety is a primary concern, during any activity, including construction utilizing maxi-HDD equipment and procedures.

No-Dig 2010, Chicago, IL, US. It is important to properly use the drilling fluid for the initial pilot bore and reaming operations, and to accurately locate and track the bore path. This technique involves drilling a pilot bore, generally along a closely defined shallow arc, and then, if necessary, enlarging the bore using a reamer or hole opener to create a bore large enough to accept the new PE100 pipe, which is generally pulled in behind a reamer. High-density polyethylene pipes are now widely used in the sewer industry. UI. TR-46, Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of High Density Polyethylene Pipe, was therefore developed to serve as an inclusive document, providing practices for selection and placement of HDPE pipe using mini-HDD. HDPE is a polyethylene thermoplastic made from petroleum. Table 5 - Safe Pull Loads for HDPE Pipes 24. iii Foreword Polyethylene Pipe for Horizontal Directional Drilling is one of the chapters being pre-pared for inclusion in the Plastics Pipe Institutes PPI Handbook of Polyethylene Pip-ing, which will be issued as a complete volume in the future. In the absence of anti-buoyancy techniques, such as internal water ballast, the frictional drag developed within the borehole is generally much greater than that developed outside, because of the high buoyant weight for an empty PE pipe. Horizontal directional drilling is the most cost-effective and efficient method for highway bores. The benefits of using HDPE for this applications are: Pipefusion provides polyethylene pipe, on-site fusion services, molded and fabricated fittings and custom fabrication to Directional Drilling contractors across Canada. 0000009554 00000 n The risk of scoring of the pipe can be minimised by ensuring the reamed bore is of sufficient diameter and properly cleaned and proved prior to pipe pull-back.
