Casing & Tubing

Casing is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors such as the interference-fit Permalok® interlocking push-on joint, can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakes and rivers. Tubing is the conduit through which oil and gas are brought from the producing formations to the field surface facilities for processing.
