Webb23 maj 2011 · With ductile iron pipe, the thrust area is thus based on the outside diameter of the pipe, as the outside of the spigot of the pipe can normally be pressurized nd potentially slide in piston-like fashion, within a gasket normally retained in a bell/socket gasket groove of such piping. Webbthrust blocks to absorb pipeline axial thrust. Thrust control is typically needed at the end of the pipeline and at in- line control valves. Follow the pipe manufacturer’s recommendations for thrust control. In absence of manufacturer’s data, design thrust blocks using 210-NEH-636-52 Thermal Effects

WebbThrust blocks are required where fittings are used to change the direction (i.e., at ties, elbows, wyes, caps, valves, hydrants, and reducers) of buried piping systems. The size and type of thrust blocks depend on pipe size, line pressure & temperature, type of fitting, degree of bend, and type of soil. When should thrust blocks be installed?

Thrust … WebbThe term thrust block refers to any type of element that will absorb, or take the thrust that occurs when a liquid is forced through a conduit system. For example a water line that is installed underground, will exert substantial force on any joint or turn of direction in the piping or conduit system. state game land shooting ranges in pa
