Abstract
A joint for joining together lengths of fiberglass reinforced pipe or assembling joint components to a length of fiberglass reinforced pipe has abrasive threads capable of cutting matching threads into the surface of the pipes being joined. The abrasive threaded coupling requires no shaving or other surface preparation of the pipes to be joined for assembly of the joint. If a bonding adhesive is used in the joint, the joint is not sensitive to and will not be damaged by the movement of the joint before the adhesive has cured. The abrasive threaded joint can be modified for use as a pipe coupling, fitting, flange, adapter or a quick and effective repair coupling.
