Abstract
A corrosion-resistant long heater is formed by encasing segments of metal-sheathed, mineral-insulated, electrical resistance heating elements within a metal oversheath which oversheath is substantially completely impermeable and is compressed inwardly to create metal-to-metal contacts between the sheath and the encased elements.
