An optical assurance cap, having a body including a through-bore, a first section having a first light absorption coefficient, a second section having a second light absorption coefficient, and a third section having a third light absorption coefficient, operatively arranged between the first section and the second section, wherein the first and second light absorption coefficients form a first combined light absorption coefficient, and the first, second, and third light absorption coefficients form a second combined light absorption coefficient, the first combined light absorption coefficient being less than the second combined light absorption coefficient.

Various embodiments include a tool for leakage testing a component, along with a related testing method. In some cases, the tool includes: a seal assembly for sealing an opening in the component, the seal assembly having: a front plate defining a pressure chamber around the opening in the component; a collar coupled with the front plate and surrounding sidewalls of the component; an insert extending between the front plate and the collar; an annular seal member between the collar and the insert; and a floating seal between the collar and the front plate, wherein the seal assembly is configured to flexibly seal the opening in the component; and a valve for controlling fluid flow into the pressure chamber during the leakage testing of the component.

An adapter system for a check valve which comprises a housing open at the bottom and a lateral wall pierced by a hole, and a flap fitted inside the housing and movable between a shut-off position in which the flap shuts off the hole and a free position in which the flap does not shut off the hole. A plug is provided for being inserted into the hole through an end face and a stop is provided for being placed against the lateral wall of the housing opposite the lateral wall pierced by the hole and comprising an attachment device provided for attaching the stop to the housing and provided so that the plug comes to rest against the stop. Such an adapter system may be installed without it being necessary to dismantle the housing.

Disclosed are a system and method in which the maximum back pressure determination and monitoring are provided in plugs allowing fluid and gas flow to be blocked in pipe lines with gravity flow such as sewage and rain water pipe lines.

An optical assurance cap, having a body including a through-bore, a first section having a first light absorption coefficient, a second section having a second light absorption coefficient, and a third section having a third light absorption coefficient, operatively arranged between the first section and the second section, wherein the first and second light absorption coefficients form a first combined light absorption coefficient, and the first, second, and third light absorption coefficients form a second combined light absorption coefficient, the first combined light absorption coefficient being less than the second combined light absorption coefficient.

A system and method for non-destructive, in situ, positive material identification of a pipe selects a plurality of test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/10%, a carbon percentage within +/25%, and a manganese percentage within +/20% of a known material standard.

An apparatus for hydrostatic testing of openings in items surrounded by a flange, such as flanged pipe sections, flanged pipelines, flanged hose assemblies, as well as other flanged equipment requiring periodic pressure testing.

A system, method and apparatus for rupturing a test seal part from a vent positioned on a roof of a structure and without requiring a person on site to accomplish the same includes a test seal part, wherein the seal part removably sealably connects to the plumbing vent pipe, and a remote controlled apparatus and/or remote controller directly or indirectly ruptures the test seal part.

Smoke detection sample points and systems are described herein. One smoke detection sample point includes a body having a chamber formed within the body, a first air flow conduit formed within the body having two ends and the ends being open, to allow air to pass through the first air flow conduit between an area to be sampled and the chamber, and a second air flow conduit formed within the body having two ends with one end being open and having an air seal, to prevent air from passing through the second air flow conduit between the area to be sampled and the chamber.

A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.
