Numerous manufacturers are developing innovative devices to prevent damage that can occur to lines during civil engineering work. One such means is Trace Safe®, currently the only system for water-blocking locating wires. The heart of this innovation is a high tensile strength locatable wire with water-blocking threads. Because of simple connecting plugs, it is not necessary to remove the high-density polyethylene (HDPE) outer jacket of the locating wire. The advantages of Trace Safe lie in its strength; ease of use; lightning protection; and abrasion, compression, impact, and corrosion resistance.
Horizontal directional drilling (HDD) installations generate large volumes of spent drilling mud, which must be managed properly to avoid unnecessary treatment and disposal (T&D) costs and environmental risks. Contractors and owners often choose to solidify drilling mud on-site with superabsorbent polymers (SAPs) because of the cost savings, ease of use, and environmental benefits that SAPs offer. The following SAP FAQs and dosing recommendations may help you to plan a more efficient and safe HDD operation:
