During pipeline commissioning, end caps are installed to close off pipe sections so that pressure can be applied and monitored.<\/p>\n<p data-start=\"1670\" data-end=\"1768\">A properly fused HDPE end cap provides a reliable seal, allowing accurate testing without leakage.<\/p>\n<hr data-start=\"1770\" data-end=\"1773\" \/>\n<h3 data-start=\"1775\" data-end=\"1825\">Temporary Pipeline Closure During Construction<\/h3>\n<p data-start=\"1827\" data-end=\"1906\">In many projects, pipelines are installed in stages.
