Pipe Load Bearing strength of Casing Spacers in Carrier Pipeline Installation

In pipelines it is frequently necessary to position one or more pipes carrying a linemedium within a rigid outer casing. This carrier pipe within an outer casingarrangement is frequently provided for water and sewer mains within highway andrailroad crossing pipe casings to maintain carrier pipe alignment, restrain the carrierpipe against floatation or other movement, or maintain the carrier pipe in a fixedposition and orientation such as per grade requirements in the case of a gravitysewer. Casing spacers are for fixing pipes position, isolating carrier pipemechanically, and chemically from pipe casings. A casing spacer includes first andsecond elongated, steel shell members comprised of stainless steel or high strengthsteel with corrosion inhibiting coatings, with each shell member having a semicircularcross section for engaging and enclosing a carrier pipe within an outercasing. In this paper, the loading capacity of casing spacers in different types ofcarrier pipelines is calculated. As a case stay, the Qatar world cup championshipstadiums infrastructure projects are evaluated. The result shows, the stainless-steelcasing spacers loading capacity that used in mentioned projects are much more thanthe pipelines weight.
