PVC pipe

CertainTeed Certa-Lok™ C900/RJ PVC Pipe is designed for use in directional drilling and other restrained joint applications. The pipe requires no special heat-fusion equipment, saving contractors a significant amount of time and money. Its joints are assembled as the pullback continues, so streets remain open and clear. And compared to alternate thermoplastic materials, higher-strength PVC requires a much thinner wall to achieve the same pressure rating. Because of this, a smaller diameter pipe can often be used.

Expansion joints

The Force Balanced Flex-Tend® Flexible Expansion Joint from EBAA Iron can accommodate pressure-induced thrust forces. It uses an additional water chamber piston that acts in the equal and opposite direction of the imparting thrust and neutralizes the thrust forces. This allows designers to use flexible expansion joints in applications where thrust blocks or other force-restricting devices are not applicable. Force balanced joints also protect pipelines that serve structures from shear. EBAA Iron Inc., Eastland, TX, 800-433-1716, www.ebaa.com

The new McElroy In-Field Tensile Tester gives contractors and pipeliners the ability to test high-density polyethylene (HDPE) butt fusion joints in the field. A hand-pump system safely tests coupons from pipes sized 2" IPS and larger. The tester also incorporates a template that is attached to the pipe to create a coupon through the use of a drill and reciprocating saw. The coupon is then inserted into the hand-pump tensile test unit that performs a destructive test to qualitatively pass or fail the joint. McElroy Manufacturing, Tulsa, OK, www.mcelroy.com
