These limit stops are fabricated from carbon steel with stainless steel inner components. These supports function to prevent excessive stress on the pipe by limiting motion due to earthquakes or other similar events.
They range in size between 20 7/8″ and 22 7/8″ from pin to pin. The load ranges between 12,500 lb. and 21,100 lb. The limit stops are passive restraints that are designed for a maximum thermal expansion of 5″, but can be preset for any specified amount of movement. They will be utilized in an oil refinery overseas.
