A pipe insulation system has a spacer wrap, an insulation material and a cladding. The spacer wrap has an upper surface and a lower surface. The upper surface of the spacer wrap has a plurality of convex protrusions. The upper surface is positioned against a pipe. The insulation material has an inner surface and an outer surface. The insulation material is positioned exterior to the lower surface of the spacer wrap. The cladding has an interior surface and an exterior surface. The cladding is positioned exterior to the outer surface of the insulation material.

There is provided a flow pipe including: a pipe body including a side wall having an opening portion; and a heat insulator arranged at an inner peripheral side of the pipe body and having a flow path through which a fluid flows. The heat insulator has an outer peripheral surface facing with the side wall, and the outer peripheral surface has a flow path structure configured to form a flow path that guides a water droplet generated between the heat insulator and the pipe body to the opening portion.

An insulated assembly, including a pipe and a substantially rigid insulation board, is provided. The pipe includes a cylindrical outer surface defining a first diameter. The insulation board is disposed around the outer surface of the pipe and includes an inner surface defining a second diameter. The second diameter is substantially equal to the first diameter. The inner surface includes a plurality of grooves. Each of the plurality of grooves includes first and second opposed sidewalls. The insulation board includes a material having a compressive strength and a flexural strength, the compressive strength includes a value between fifteen pounds per square inch and one hundred pounds per square inch, and the flexural strength includes a value between forty pounds per square inch and one hundred pounds per square inch.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

A heat-insulated pipe assembly includes a pipe allowing a fluid to flow therethrough, and a heat insulating member covers at least a part of the pipe. The pipe is used in an exhaust gas purification system using an SCR catalyst. The heat insulating member has a closed-cell structure and suppresses an increase in a temperature of the fluid due to heat exchange with air. In the exhaust gas purification system using the SCR catalyst, the interior of the pipes is thermally insulated from the exterior by the heat insulating member. Thereby an increase in the temperature of the fluid flowing through the pipe due to heat exchange with air is suppressed.

The heat insulator has an outer peripheral surface facing with the side wall, and the outer peripheral surface has a flow path structure configured to form a flow path that guides a water droplet generated between the heat insulator and the pipe body to the opening portion.

A modular heater assembly includes resistive heaters disposed along sections of a fluid conduit system, insulation members around the resistive heaters, and at least one insulation block around a fitting. The fitting is configured to join at least two adjacent sections of the fluid conduit system and defines an exterior geometric profile. The insulation block includes a central recess extending axially in a direction of one of the at least two adjacent sections and defining an internal geometric profile substantially matching the external geometric profile of the fitting, and a peripheral aperture. The peripheral aperture is open to the central recess, defines an internal geometric profile substantially matching an external geometric profile of another of the at least two adjacent sections, extends through a sidewall of the insulation block, and is axially aligned with the another of the at least two adjacent sections.
