EBAA Iron, Inc. is the leader in pipe joint restraint and flexible expansion joints for water and wastewater pipelines, and the only manufactures of the MEGALUG. The Change in Length (ΔL) due to thermal contraction/expansion is given by: ΔL = L (ΔT)(C) Where: L
Pipe expansion joints are necessary in systems that convey high temperature substances such as steam or exhaust gases, or to absorb movement and vibration. A typical joint is a bellows of metal (most commonly stainless HDPE), plastic (such as PTFE), fabric (such as …
9-1 1--2-91 P J 01, 201 MADE IN U.S.A. P IMPORTANT INFORMATION High density polyethylene pipe (HDPE) has several properties that make it very different from “tradi-tional” water works pipe materials: • Coefficient of thermal expansion is over 10 times
Axial movement of the pipe could result in damage to the pipeline, expansion joint or other equipment. When dividing a pipeline into independent expanding and contracting segments by the placement of main anchors and intermediate anchors, it is desirable to make …
* HDPE pipe may face; PE density of 94% of the salt water, because it is up to 96% of the fresh water on the HDPE pipe filled with water even if the water is suitable to swim in. Therefore, be reduced as far as large parts of the ground may be left floating on the water coined.
1. HDPE Pipe. At HDPE pipe connections to fittings and/or other pipe materials, the inside of the HDPE pipe shall be reinforced by inserting a two piece wedge style stainless HDPE stiffener/insert. Insert shall be properly sized and approved by the 2.
