HDPE pipe are widely used for trenchless sewer lateral replacement. water tanks, spoil containers, etc.) 450046. 0000019826 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. This handbook will cover 380 0 obj <>stream Joints in traditional piping materials are the biggest source of leakage. H0+X u7A@>&F While ASTM International F1962 may be purchased from the ASTM International website (www.ASTM.org), the overall guidelines, including preliminary investigation and implementation procedures, as well as the detailed design methodology for selection of the proper pipe strength, are reflected inChapter 12 of the Plastic Pipe Institute (PPI) Handbook of Polyethylene Pipe, In addition, the ASTM International F1962 methodology is now available in a free online tool designated asPPI BoreAid. 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. Horizontal Directional Drilling Plastic Pipe (HDPE & MDPE) Home; HDD (Polyethylene Pipe) - Input; Please [ Log . 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. It should not be used in place of the advice from a licensed Professional Engineer. 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. This picture shows a small barrel reamer attached to the new pipe ready to be pulled in. Pipes installed by HDD may increase in diameter, and therefore decrease in length, when pressurised, which will result in some axial tension. DNVGL-ST-F101: Code Check ; ASME B31.4/B31.8 Code Check . A result shown in Green and with a Safety Factor endstream endobj startxref Midi-HDD may be employed for boring paths up to 1,000 feet in length, at depths as much as 75 feet, and placing pipes up to 24 inches diameter. The traversing pipeline can fully meet the design curve and deep buried, and the quality is safe and reliable.

Problematic soil conditions include large grain content in the form of coarse gravel, cobbles, and boulders. Complete Tooling Line ( All Types of Bits, Subs, Housings) Drill Rod Drilling Muds & Fluids Mule Tape Couplers Darts HDPE Pipe PVC Pipe & Fittings PVC Glue The bore is steered to create an initial hole at the required line and grade. Horizontal directional drilling is often used where open cut installations are not feasible, such as road and river crossings. The pipe string is attached to the back-reamer through a swivel device. He can be reached at lslavin@ieee.org. select the wall type based on those results and other factors. Potential safety issues fall into two general categories: Although not considered to be hazardous materials, the proper handling and disposal of drilling fluid is also discussed to avoid possible environmental issues. was originally approved in 1999, following development within the ASTMs F17.67 Trenchless Technology Subcommittee. Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. It is the only system that has the capability of verifying the location. Typical Entry Site Layout. Depending on the location and extent of the operation, a variety of permits or approvals may be required, possibly from federal, state or local jurisdictions.

Weight is calculated using DN and Minimum wall plus 6% for use in estimating fluid flow. FIGURE 1 illustrates the operation in a city or urban application. This method applies tension to the PE100 pipe during installation. Drilling fluid may escape to the surface or other facilities unless carefully managed. It can be used on land, sea, urban areas and rivers. What truly separates HDPE from other pipe materials is that when it is fused together (using a wide variety of standard and custom components, fittings and joining systems) it creates one homogenous system that matches the same technical and environmental specifications as the HDPE pipe. Drilling mud is used to cool the cutter and transmitter electronics, to flush excavated soil from the borehole and to lubricate the borehole. HDPE conduit, also known as PE conduit, is the preferred material to house and protect electrical power and communications cables in typical applications such as power utilities, telecommunications, CATV, SCADA, FTTH, ITS, highway lighting, and other underground utilities. 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. There are three types of locating equipment for locating the bore head: the walk-over locating system, the wire-line locating system and the gyro guided drilling, where a full inertial navigation system is located close to the drill head. HDPE water pressure pipes can be connected by a process called butt fusion, where the ends of the pipes are heated and joined together. One of the significant contributions of ASTM International F1962 is the provision of a rational, analytical method for selecting the polyethylene pipe strength based upon the estimated installation and post-installation (operational) loads on the polyethylene pipe. ;0CKh6sKjrmlq9vwiJ%)m5]UWd Add: 13th F, Longyu International Building, Zhengzhou Area(Zhengdong), China(Henan) Pilot Free Trade Zone.
