  • Deck Gear: Low

    A comparative low-friction ring will weigh less than half an ounce and have an SWL of 3,500lb. Again, though, while low-friction rings can replace blocks in many situations, there's a caveat: doing so will increase the friction within the system. These are, after all, “low” friction, not “no” friction rings we're talking about here.

  • Bottom Hole Pressure Concept | Drilling Course

    During circulation, the bottom hole pressure equals to the sum of hydrostatic pressure and frictions generated through the circulating system. In the case of using a rotating head, such as when drilling with MPD system, the bottom hole pressure is the sum of the hydrostatic pressure, annulus pressure losses and the surface backup pressure.

  • ANALYSIS 1: Alternative Foundation System

    The extensive amount of drilling created schedule delays and increased the foundation costs.end bearing piles and friction piles.Drilled Caissons are installed by augering a large hole with a diameter ranging between 30 and 72 inches and backfilling the holes with concrete.


    The off-center hole is usually lined with a primer, that is sensitive to a No. 6 blasting cap. It is essential to place the cap in the proper hole to avoid a misfire. In avalanche work it is convenient to lace the fuse tightly through the central hole and then into the off-center hole, snug against the end of the hole.

  • Drill Nomenclature and Geometry

    Drill Nomenclature-Points• Elements of Drill Points • Lip Relief Angle – Varies with the diameter of the drill and hardness of the material – On larger diameters and drills for harder materials, lip relief is decreased to as low as 8° – Drills for soft materials and small diameters have high relief angles up to 24° – Lip relief angles are measured across the margin

  • Solutions for Reducing Torque, Drag, Casing Wear and More NRPS

    within the sleeve, reducing rotating friction by 50 to 90% even at low rpms and in almost any drilling or completion fluid. The result is that surface torque is significantly reduced allowing more torque to be distributed to the bit improving drilling performance and the rate of penetration (ROP). Mud from the annulus flows into the fluid channels

    Rotary drilling is the most common method used in the US. Rotary drilling drilled shaft construction can be classified into three broad categories: (a) dry method, (b) wet method, and (c) casing method The selected method depends on the subsurface. As the design depends on the construction method, it becomes part of the design process.

    Cylinder head designs are key to reducing fuel emissions and meeting strict government regulations.

  • Solid Carbide Deep

    The tool also features a low friction, TiAIN + TiN coating for long, predictable tool life. Four land margins provide stability and maximize hole quality. For the best setup stabilization, Feedmax SD230A drills should be used in conjunction with hydraulic chucks or Shrinkfit toolholders.

  • Fluids, Hole Cleaning and Tripping Optimization

    drilling. In high angle hole sections the pipe is lying on the low side of the hole creating a flow channel on the high side with reducing annular velocities towards the low side. In highly deviated holes, cuttings even when moved into the high flow area do not have very far to fall due to gravity and exhibit saltation flow.

  • Amana Tool 55295 Carbide Tipped Countersink w/Adjustable

    These tools combine carbide countersink, high-speed-steel drill bit and free-spinning, low friction depth-stop. The countersink leaves a clean hole edge and the adjustable depth-stop doesn't mar the surface. The large openings around the collar allow the chips to clear effectively and eliminate clogging. Quick release 1/4" hex shank with slow spiral, HSS?M2 fully ground drill bit included.

  • DIY: Replacing a Mainsheet Traveler

    I love the fact that an old boat can give you as much sailing pleasure as an expensive new one. The only proviso for me is that the sail handling systems be absolutely top-notch. Replacing hardware like mainsheet travelers, genoa lead cars, boom vangs and lead blocks with new, low-friction gear will repay you many times over in ease of handling and improved efficiency.A case in point was a
