Concrete pressure pipe is highly customizable (see chart below), enabling engineers to tackle tight spaces, long stretches of hilly terrain, and precise sequencing requirements without special bedding and backfill procedures. Operators like the pipe as it requires little maintenance over 70-, 80-, and even 90-year-or-more time spans. The pipe is available as:<\/p><!-- \/wp:paragraph -->\r\r <!-- wp:list {\"ordered\":false} --><ul><!-- wp:list-item --><li>Two types of prestressed concrete cylinder pipe (PCCP) \u2014 L-301 and E-301. Manufacturing begins with a steel cylinder with steel joint rings attached. Concrete is placed inside or around the steel cylinder and allowed to cure. The pipe is then circumferentially prestressed by helically wrapping high-tensile-strength steel wire around a concrete-lined steel cylinder (L-301) or a concrete core containing the steel cylinder (E-301). The wire wrap places the steel cylinder and concrete core in a state of circumferential compression, allowing the pipe to withstand hydrostatic pressure and external loads. The high compressive strength of concrete and the high tensile strength of steel combine to form a robust structure capable of withstanding a wide range of loading conditions.<\/li><!-- \/wp:list-item --><\/ul><!-- \/wp:list --><!-- wp:group {\"layout\":{\"type\":\"constrained\"}} --><div class=\"wp-block-group\"> \r <!-- wp:group {\"layout\":{\"type\":\"constrained\"}} --><div class=\"wp-block-group\">\r <!-- wp:heading {\"level\":3} --><h3>Water Transmission<\/h3><!-- \/wp:heading -->\r <!-- wp:group {\"layout\":{\"type\":\"constrained\"}} --><div class=\"wp-block-group\">\r  <!-- wp:paragraph --><p><strong>Who:<\/strong> Canyon Regional Water Authority, New Braunfels, Texas <strong>Engineer:<\/strong> River City Engineering, New Braunfels <strong>Contractor:<\/strong> Mountain Cascade Inc., Mansfield, Texas <strong>Material:<\/strong> B-303 bar-wrapped concrete cylinder pipe<\/p><!-- \/wp:paragraph -->\r  <!-- wp:paragraph --><p>Canyon Regional Water Authority managers specified 46,000 feet of 30-inch B-303 bar-wrapped concrete cylinder pipe to connect two pipelines because an existing concrete pressure pipeline has performed well over time.
