Abstract: A bimodal poly(ethylene-co-1-hexene) copolymer composition, methods of making and using, and manufactured articles made therefrom and uses thereof.

Abstract: The present invention relates to a method of coating a pipeline field joint comprising the steps of (a) applying a layer of a coating material composition comprising (i) a propylene polymer and (ii) a substantially linear ethylene copolymer, a linear ethylene copolymer, or mixtures thereof, to the uncoated region of the field joint, preferably the coating is applied by injection molding.

Abstract: A polypropylene/thermoplastic vulcanizate insulative coating is disclosed. The coating is particularly suited for subsea applications, in particular providing insulation to joints in oil well pipes and other machinery. The coating exhibits mechanical properties superior to joint insulation coatings known in the art, especially in combination with other insulation coatings.

Abstract: The present invention relates to a method of coating a pipeline field joint comprising the steps of (1) applying a layer of a first coating material comprising a substantially linear ethylene polymer, a linear ethylene polymer, or an olefin block copolymer to the uncoated region of the field joint and (2) subsequently applying a layer of a second coating material comprising a polyurethane, an epoxy, or a cross linked polyethylene to the field joint.

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.
