US 12,624,778 B1 · Polyurethane pipe thread tape assembly

Abstract

Some embodiments include a polyurethane pipe thread tape and a pipe thread tape assembly including the pipe thread tape and a paper liner, and in some instances a casting layer. The pipe thread tape can include a polyurethane film and an adhesive. The pipe thread tape can be wrapped around external threads at an end region of a first piping component. The wrapped end region of the first piping component can be attached to an internally threaded end region of the second piping component. The pipe thread tape can be separated from a paper liner by stretching a pipe thread tape assembly lengthwise, the paper liner initially being coupled with the pipe thread tape via the adhesive, and the pipe thread tape having greater stretchiness than the paper liner. The pipe thread tape can be provided in and dispensed from packaging, in some instances.

Dependent claims

A method of installing pipe thread tape between a first piping component and a second piping component, the method comprising:

wrapping the pipe thread tape around external threads at an end region of the first piping component, resulting in a wrapped end region of the first piping component, wherein:
the pipe thread tape comprises a polyurethane film and an adhesive, such that the adhesive is at a first side of pipe thread tape, and the wrapped end region of the first piping component has the first side of the pipe thread tape against the end region of the first piping component such that the adhesive contacts the external threads,
the polyurethane film having an elongation upon breaking between 5 inches and 24 inches, wherein the elongation upon breaking is measured as a difference between an original length of the polyurethane film and a final length of the polyurethane film at break, in combination with the adhesive having a peel strength between 125 g/25 mm and 225 g/25 mm;
and
attaching the wrapped end region of the first piping component to an internally threaded end region of the second piping component.

A method of using pipe thread tape, the method comprising:

providing a pipe thread tape assembly in packaging, the pipe thread tape assembly comprising:
a pipe thread tape, the pipe thread tape comprising a polyurethane film and an adhesive, such that the adhesive is at a first side of pipe thread tape, and
a paper liner coupled to the pipe thread tape via the adhesive, dispensing the pipe thread tape assembly from the packaging;
separating the paper liner from the pipe thread tape, thereby exposing the adhesive, wherein separating the pipe thread tape from the paper liner comprises:
stretching the pipe thread tape assembly lengthwise such that an entire width of the paper liner tears without tearing the polyurethane film;
and
wrapping the pipe thread tape around external threads at an end region of a piping component, such that the first side of the pipe thread tape is against the end region of the piping component with the adhesive contacting the external threads.
