The tools and techniques used in the horizontal directional drilling (HDD) process are an. outgrowth of the oil well drilling industry. The components of a horizontal drilling rig used for. pipeline construction are similar to those of an oil well drilling rig with the major exception being. that a horizontal drilling rig is equipped with an inclined ramp as opposed to a vertical mast. HDD.

The chemical compound potassium chloride (KCl) is a metal halide salt composed of potassium and chloride.It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water and its solutions have a salt-like taste.olutions of KCl are common standards, for example for calibration of the electrical conductivity of (ionic) solutions, since KCl solutions are stable, allowing for reproducible measurements. In aqueous solution, it is essentially fully ionized into solvated K + and Cl â ions.
