SFJ ® & SPFJ ®

Being at the forefront of innovation in the drilling industry has allowed Sharpe to develop our two proprietary patented rugged premium casing / tubing connections:

With almost 1 million metres of casing distributed to the Australian onshore market, Sharpe’s SFJ ® and SPFJ ® are proven gas tight seal connections and tested for vertical, horizontal and deviated wells.

The majority of SFJ ® and SPFJ ® casing is run within the rough and harsh environment of underground coal mining, CSG (Coal Seam Gas) and CBM (Coal Bed Methane) industries.
