Abstract:
An apparatus and method for applying a protective material to the girth weld of pipe. The apparatus is particularly suited for protecting a pipe that, except for the ends adjacent to the weld, is protected by layer of a semi-interpenetrating polymer network of epoxy and polyolefin resins. Using the apparatus and method, the protective material is firmly bonded to both the exposed steel end and the pre-existing protective layer.
