fiberglass shell

FRP, a composite material composed of a polymer matrix reinforced with fibers, boasts exceptional strength-to-weight ratio, corrosion resistance, and durability. These attributes make it an ideal choice for manufacturing pipes used in harsh environments where conventional materials like steel or concrete might corrode or deteriorate over time. The use of FRP in spraying pipes ensures a longer lifespan and reduced maintenance costs, thus providing an economical solution.

It was not until the development of the hydraulic drifter in the 1950s that rock drilling truly entered the modern eradrifter for rock drill. This innovative tool used high-pressure hydraulic fluid to power a piston that rotated the drill bit, allowing for much greater penetration rates and precision. The hydraulic drifter quickly became the go-to tool for drilling holes in hard rock, paving the way for many of the major engineering projects of the time.
