Abstract

The steel-plastic composite pipe end sealing device comprises a sealing heating ring, the inner side wall of one end of the sealing heating ring is provided with a composite inserting groove allowinga to-be-sealed steel-plastic composite pipe to be inserted, and a sealing ring used for sealing the pipe end of the to-be-sealed steel-plastic composite pipe is arranged in the composite inserting groove. An inner-diameter non-heating ring is arranged on the inner side wall of the sealing heating ring, a first cooling water channel is arranged in the inner-diameter non-heating ring, cooling watercan flow in the inner-diameter non-heating ring through the first cooling water channel, an outer-diameter non-heating ring is arranged on the outer side wall of the sealing heating ring, and a secondcooling water channel is arranged in the outer-diameter non-heating ring. Cooling water can flow in the outer-diameter non-heating ring through the second cooling water channel. The sealing device has the advantages that molten plastic of the pipe end of the steel-plastic composite pipe and the sealing ring cannot overflow, and the effect that a whole sealing pipe section is flat, smooth and freeof overflowing is achieved.

Description
