Over the past two decades in the HDD industry, the use of wash pipe for surface casing has become more popular. Introducing Holly Pipe’s revolutionary solution: N-Series Casing, Available in 7 to 18 5/8 inch OD, and 15, 20, 32 & 46 foot lengths. Stabilize the pilot bore, prevent hydro-fractures and cave in, and create a suitable backstop for pushing drill pipe. Our N-Series Casing remedies a plethora of hang-ups related to drilling in alluvial formations. The picture below shows a driller utilizing N-Series Casing (16” OD) on a West coast shore approach as assistants make up a connection with manual tongs. N-Series Casing is unique as it can be reused over and over again, making up and breaking out with manual or hydraulic tongs. The value of keeping inadvertent returns at bay is priceless, and instead of wasting time welding or losing valuable mud, N-Series Casing can help realize profitable returns by enabling drillers to “in-case” the surface of the bore hole.
