A wellhead housing a supports a string of casing in tension by using a load ring. The load ring mounts to the exterior of a casing hanger which secures to the upper end of the string of casing. The load ring is split, resilient and outwardly biased. The load ring is retained during the running of the casing. The running tool then releases the load ring to spring outward to support the load. The load ring has wickers on its exterior that mate with wickers in the interior of the bore. |
