horizontal directional drilling hdpe pipe
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. sufficient tensile strength to meet the required tensile forces, based New York, NY: ASME, 2008. 0000015903 00000 n The construction area is relatively small and the construction period is relatively short. The first stage drills a pilot hole on the designed path, and the second stage (reaming) enlarges the hole by passing a larger cutting tool known as the back reamer. Thus, ASTM F1962 provides a means of determining project feasibility, as well as initial design information. Calculator allows, users are recommended to review PPI TR-46 and/or ASTM Truly international membership currently comprising 13 member companies: Borealis, Borouge, FPC, INEOS O&P, IRPC, Korea Petrochemical IND.

However, they are sufficiently general to consider the possible implementation of anti-buoyancy measures to reduce these otherwise high frictional forces. Such effects are independent of the pipe stiffness, pipe diameter, borehole clearance, radius of curvature or direction of curvature, and, in some cases become a major consideration due to their compounding effect. [citation needed], The process starts with the receiving hole and entrance pits. 19), PR-277-144507-Z01 Installation of Pipelines by Horizontal Directional Drilling Engineering Design Guide (Arlington, VA: Pipeline Research Council Safety is a primary concern, during any activity, including construction utilizing maxi-HDD equipment and procedures. \K~[QvKnoD>3QV,0rl!BgH;h#cl{Y u~\L5>?t=aX`GS]r@r&{BO9wj_ 0000016763 00000 n As with any pipe pulling technique, the movement of the drill string and the pipe string should be monitored. 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. HDD Analyser performs the pipeline stress analysis and HDD design calculation in compliance with the International Codes and Standards. The technique is routinely used when conventional trenching or excavating is not practical or when minimal surface disturbance is required. 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. Gyro-based locating system The gyro based system is fully autonomous and therefore one of the most accurate systems where sufficient diameter, HDD Design Guideline Task Committee of the Technical Committee on Trenchless Installation of Pipelines (TIPS) of the Pipeline Division of the American Society of Civil Engineers. Lawrence Slavin, Ph.D., provides outside plant consulting services as a member of IEEE, the worlds largest technical professional organization dedicated to advancing technology for the benefit of humanity. Coiled pipe generally has significant degrees of curvature and ovality, and as these prevent electrofusion (or mechanical joints) of good quality being produced, as well as increasing drag and the risk of scoring damage during insertion, the pipe should be passed through a straightener re-rounder before insertion. Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. To improve your experience, other cookies may be used: you can choose to disable them. Example of Capstan Effect (Courtesy of Outside Plant Consulting Services, Inc.). Mini-HDD applications, for instance, tend to contain bore paths with additional curvature because of the need to avoid known obstacles or follow a curved right-of-way, as well as more subtle curvature due to path corrections characteristic or typically less precisely controlled installations. 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.

All material subject to strictly enforced copyright laws. 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. ?5Hb0CB$ 17C``!Dc@ q HDPE pipes are ideal for pulling through long, underground holes as they are flexible, robust, and resistant to almost all aggressive elements. This is the basis of MAB-7 (2020), MAB Guidelines for Use of Mini-Horizontal Directional Drilling for Placement of HDPE (PE4710) Pipe in Municipal Applications, as referenced in the 2022 edition of ASTM F1962. Membership; Articles; Analyses . Drilling uids are designed to match the soil and cutter. ;0CKh6sKjrmlq9vwiJ%)m5]UWd No-Dig 2010, Chicago, IL, US. 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.

At diameters up to and including 180mm the new pipe can be supplied as a coil, and this will be loaded into and dispensed from a coil trailer, positioned adjacent to or over the entry excavation. 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. Typical Maxi-HDD Operation (Courtesy of Murphy Pipeline Contractors), FIGURE 2. hb```b``d`a`` @p!y 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. The pipe entry side, opposite the drill rig, must accommodate the long length of assembled (fused) pipe. 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. HDD Analyser is a comprehensive program for the design analysis of pipelines crossings by horizontal direction drilling methodology. The cutting head is then removed and a back-reamer attached. Dead (empty) weight of the pipe above ground, Buoyant weight of the submerged pipe, possibly reduced by use of ballast). <<32159D5C8C60A744B61AE13533FBF1FA>]>> Wire-line locating system The wire-line system is a magnetic guidance system. As the name denotes, trenchless technology requires few or no trenches to be dug for the maintenance work to be done and can be defined as, A family of methods, materials, and equipment capable of being used for the installation of new or replacement or the rehabilitation of existing underground infrastructure.. Horizontal Directional Drilling (HDD) Horizontal Directional Drilling (HDD) is often used to install HDPE pipe in situations where an obstacle, either above ground or below the surface, does not allow traditional installation methods to be used. This material is significantly tougher than older, previously used PE products, facilitating successful completion of more complicated, difficult maxi-HDD projects. [1], Although often used interchangeably, the terms directional boring and horizontal directional drilling are distinct in that they convey a different sense of scale. CANTEX's CAN>LOC and CAN>GRIP systems offer many benefits over HDPE, which is the conduit most used for HDD applications. ASTM International F1962, Standard Guide for Use of Maxi-Horizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit Under Obstacles, Including River Crossings, provides recommended procedures for the placement of PE pipe using maxi-HDD. Tensions induced in the PE pipe, as it passes any curve, become amplified because the tensile forces tend to pull the pipe against the curved surface. Pipe entry point is at the opposite end of the drill rig location, which coincides with the pipe exit., shows the drilling operation proceeding from right to left, in contrast to. This phenomenon is referred to as the capstan effect, as it is the principle of the capstan winch, as illustrated in. FIGURE 2 illustrates a typical geometry for a maxi-HDD operation, in this case corresponding to a river crossing. 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. 4506 0 obj <>stream The image above shows a sonde and battery fitted inside a slant face drilling head. These two images show a small directional drilling rig being unloaded to install 100 metres of 100mm PE distribution main, and in place ready to start drilling. In contrast, the convenient model employed in ASTM F1962 results in a very low magnitude effect, which is directly added to the estimated pulling forces, due to frictional drag, including the capstan effect. Add: 13th F, Longyu International Building, Zhengzhou Area(Zhengdong), China(Henan) Pilot Free Trade Zone. h4~r Supporting the 10 main sections, several appendices provide the physical properties of selected PE material, as well as a means of determining the post-installation loads and pipe deflection. Most soil and rock types can be drilled with the appropriate tooling and processes. Joints in traditional piping materials are the biggest source of leakage. 0000004689 00000 n Thus, ASTM International F 1962 provides a means of determining project feasibility, as well as initial design information. 0000019257 00000 n The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A's) of all the elements through the pipe system value chain: design, materials, construction, operation & maintenance, and environmental issues. Although pipe stiffness effects may generally be ignored for flexible PE pipe, there is a potentially important effect can be due to route bends or any path curvature of significance. The image above shows a straightener re-rounder being used on a 180mm pipe, and whilst it is in the trench here, it can be attached to the coil trailer if so desired. This method has a very small potential damage footprint provided that adjacent buried infrastructure can be accurately located. The pulling load on the polyethylene pipe must not exceed the allowable tensile load, or safe pull strength of the pipe. 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. Horizontal drilling or Utility Installation Directional Drilling, minimizes environmental impact and is often used when trenching or excavating is not a practical or viable option. Horizontal Directional Drilling B&B Supply, Inc. provides you with the equipment and supplies you need to bore it right the first time. [citation needed], Horizontal directional drilling is done with the help of a viscous fluid known as drilling fluid.
