Abstract: The present disclosure provides a die assembly for producing a microcapillary film. The die assembly includes a first die plate, a second die plate, a plurality of multi-jackbolt tensioners connecting the first die plate to the second die plate, a manifold, and a plurality of nozzles. The manifold is located between the pair of die plates and defines a plurality of film channels therebetween. The plurality of film channels converge into an elongate outlet, wherein a thermoplastic material is extrudable through the plurality of film channels and the elongate outlet to form a microcapillary film. The plurality of nozzles are located between the plurality of film channels. The plurality of nozzles are operatively connected to a source of channel fluid for emitting the channel fluid between layers of the microcapillary film, whereby a plurality of microcapillary channels are formed in the microcapillary film.

Abstract: The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.
