A coupler and a method for securing foam tube insulation elements to one another for pipes, comprising of a strip having a top surface and a bottom surface. The top surface may have a series of tab-like projections that define openings between the top surface and the bottom surface. The top surface may also have a series of teeth.
A insulating wrap includes a flexible elongate body of insulating material adapted to be wrapped in a helical fashion around an object, such as a pipe. The body has a first end and a second end. A first tie strap is secured by a first fastener to the first end of the body to facilitate the body being secured to the pipe. A second tie strap is secured by a second fastener to the second end of the body to facilitate the body being secured to the pipe.
A fastener element with a sheet-form base and an array of wedge-shaped engageable elements molded integrally with a surface of the sheet-form base. The wedge-shaped elements each have a steep side and a gradually rising side, and are arranged with their steep sides all directed in a common sense, such that the array can engage a similar array of oppositely-directed wedge-shaped elements to resist shear motion. The distal edges of the wedges are curved in top view.
