By utilizing a high-strength Acetal (POM) half-round rod, this assembly creates a point contact that eliminates water traps and crevice corrosion at support points.<\/p>\n<h3>What Is a U Bolt with Half Round Rod?<\/h3>\n<p>A U-bolt with a half-round rod (equivalent to I-Rod) is a specialized pipe support assembly. The half-round rod is placed between the pipe and the support beam, while the U-bolt secures the pipe. This design is widely used in pipe racks, offshore platforms, chemical plants, and power plants to provide a durable, non-corrosive interface.<\/p>\n<h3>Why Use I-Rod Equivalent Instead of Rubber or PTFE Pads?<\/h3>\n<ul>\n<li><strong>Anti-Corrosion:<\/strong> Eliminates the water-trapping &#8220;crevice&#8221; found with flat pads.<\/li>\n<li><strong>High Strength:<\/strong> Unlike rubber, Acetal does not compress or degrade under heavy loads.<\/li>\n<li><strong>Low Friction:<\/strong> Allows for thermal expansion movement without damaging the pipe.<\/li>\n<li><strong>CUI Prevention:<\/strong> Specifically designed for Corrosion Under Insulation environments.<\/li>\n<\/ul>\n<h3>Technical Specifications<\/h3>\n<table class=\"wp-block-table\">\n<thead>\n<tr>\n<th>Component<\/th>\n<th>Material \/ Standard<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Half Round Rod<\/td>\n<td>Acetal (POM) &#8211; White\/Black<\/td>\n<\/tr>\n<tr>\n<td>U-Bolt Material<\/td>\n<td>Carbon Steel (HDG) including ASTM A36, A516, A193 B7\/L7 etc, or Stainless Steel (304\/316) including A320 B8, B8M, etc.<\/td>\n<\/tr>\n<tr>\n<td>U-Bolt Standard<\/td>\n<td>DIN 3570 \/ ASME B18.31.5\/ ASTM A36 \/ A193 \/ A320, etc; we also make customized standard U bolts.
