The present invention relates to an insulating material protective cover for a valve unit. The insulating material protective cover for a valve unit, according to the present invention, comprises: a first split body including a first plate, first finishing chassis respectively coupled to both end portions of the first plate in the widthwise direction, and second plates perpendicular to the first plate and respectively coupled thereto; a second split body including a third plate, second finishing chassis respectively coupled to both end portions of the third plate in the widthwise direction, and fourth plates perpendicular to the third plate and respectively coupled thereto; and a third split body including a fifth plate, a second finishing chassis coupled to a first end portion of the fifth plate in the widthwise direction, a first finishing chassis coupled to a second end portion of the fifth plate in the widthwise direction, and a sixth plate perpendicular to the fifth plate and coupled thereto.

In combination with a pipe (213), a clamp (201) is provided which supports the pipe in a fixed position with respect to a substrate. The clamp includes first (203) and second (205) bands, wherein each of the first and second bands has an arcuate portion (209) and first and second terminal portions (211), and wherein the arcuate portions of the first and second bands are disposed in opposing relation around the surface of the pipe. A first fastener (207) extends through the first terminal portions of the first and second bands, and a second fastener extends through the second terminal portions of the first and second bands. A thermal insulator (233) is disposed between the first fastener and the first terminal portions of the first and second bands, and between the second fastener and the second terminal portions of the first and second bands.

A transition section (10) disposed between successively-spoolable electrically trace-heated PiP pipelines (12) comprises an inner pipe, an outer pipe and an annulus between the inner and outer pipes. The annulus contains heating cables (26) that extend longitudinally between annuli of the pipelines and longitudinally-spaced seals (44) that, when deactivated, allow fluid communication between the annuli of the pipelines and, when activated, isolate the annuli of the pipelines from each other. Longitudinally-spaced blocking plates (32) close the lumen of the inner pipe and define an inner chamber between them. Longitudinally-spaced openings (40) penetrate a wall of the inner pipe at locations longitudinally inboard of the blocking plates and the seals. The openings effect fluid communication between the annulus and the inner chamber and also define a diversion path for the heating cables that extends from the annulus to the inner chamber and back to the annulus
