Abstract
A restraint system for use in securing temporary flow lines that include multiple pipe sections, each pair of pipe sections connected together with a fitting or coupling such as a hammer joint coupling. The system includes multiple pluralities of endless loop slings connected end to end with a cow hitch or girth hitch knot. Disconnectable fittings (e.g., shackles) are placed every three or more slings so that easy disassembly is afforded in case of leakage or other failure. In one embodiment, a waterproof sleeve is an outer layer that surrounds or encapsulates an inner layer so that the inner layer remains dry and thus will not freeze.
