Pittsburgh Pipe has become the premier CSL testing tube manufacturer in the United States. Because of our years of steel experience and the feedback we’ve received from our customers across the country, we can design and manufacture CSL tubes to your project. We can manufacture CSL tubes to custom-fit each drilled shaft based on total length of the shaft. This process cuts down on material waste and time in the field while saving our customers money through assets that handle any degree of foundation testing.
We can thread tubes in lengths from 1 foot to 42 feet. We use malleable iron couplers to join the CSL tubes together or malleable iron caps to close off the end of the tube. Pittsburgh Pipe ships your specially designed CSL tubes straight to the job site ready to be installed. All exposed threads are carefully protected using durable thread protectors, which eliminate any potential damage during shipping. The days of cutting tubes and threading in the field are over, thanks to our manufacturing process.
