A modular weed barrier mat comprised of a double layer of tire tread sections cut from used tires arranged so that the lengths of the upper sections are perpendicular to those of the lower sections. A pair of upper sections are positioned in spaced apart relationship so as to form a gap, with a central slit array cut into two immediately adjacent lower sections accessible within the gap. A slit cut through a width of one lower section directly below one of the upper sections on either side of the central slit array allows a post to be moved into the slit and then positioned in the central slit array. Corrosion resistant fasteners are removed and replaced as needed to allow the mat to be installed or removed as desired. One embodiment features lower and upper lap portions on opposite sides of the mat for modular installation.

An apparatus for determining the integrity of a tube is provided. The apparatus includes: a body having an extension mechanism and configured to be inserted into the tube; and a flexible eddy current sensor including a flexible housing coupled to the body via the extension mechanism, and one or more coils disposed in the flexible housing. The flexible housing is selectively extendable via the extension mechanism between a first position and a second position. The one or more coils are farther away from the body when the flexible housing is in the second position than when the flexible housing is in the first position. The one or more coils electrically couple with an interior surface of the tube when the flexible housing is in the second position, and the flexible eddy current sensor is operative to selectively induce electrical currents within the tube via the one or more coils.

Apparatus and method for determining the integrity of a tube

Disclosed herein is a scanning device for performing ultrasonic nondestructive testing of a tube, comprising a housing; the housing having bottom surface that is concavely curved with cavities to accommodate a waveguide assembly and an encoder assembly; where the waveguide assembly comprises a waveguide and a probe that are in communication with one another; the waveguide having at least one surface that is contoured to match an outer surface of the tube; where the waveguide facilitates the transmission of ultrasonic signals into the tube generated by the probe; and where the encoder assembly comprises a spring loaded wheel that contacts the tube; and where the encoder assembly provides a signal indicative of a location of the probe relative to a position on the tube as the scanning device is moved in a direction of a longitudinal axis of the tube.

A visual inspection system [] includes a remote end [] that is moved through a conduit [] with a flexible pushrod []. The remote end [] having at least one carriage assembly [] with encoders [] indicating a distance traveled within the conduit []. The visual inspection device [] has a longitudinal camera [] to identify view down the length of the conduit [], but also has at least one transverse camera [] adapted to visually inspect an inside surface [] of the conduit []. Also, the transverse camera [] may be used to inspect other conduits that connect to conduit [

Remote visual inspection system

An ultrasonic probe carrier includes a base, a first side arm having a first end thereof attached to the base and a second end thereof extending outwardly from the base on one side of a tube, and a second side arm having a first end thereof attached to the base and a second end thereof extending outwardly from the base on an opposite side of the tube, at least a portion of the first and second side arms being biased towards each other to removably secure the carrier around at least a portion of a circumference of the tube. An ultrasonic probe is attached to the base, and the carrier and ultrasonic probe are rotatable around the tube to scan at least one of: the circumference of the tube and a weld disposed around the circumference of the tube.

Ultrasonic inspection probe carrier system for performing non-destructive testing

A rail section weld inspection device [] is described for inspecting a rail [] for internal defects []. A central ultrasonic (US) probe [] transmits at least one US beam [B] through the rail [] and receiving a reflected signal. At least one angled US probe [] transmits at least one US beam [A-A] through the rail [] at an oblique angle at least partially covering the same region as the central probe []. An encoder identifies the location of the US probes [] and [] along the rail [] and pairs the locations of the probes with the signals received. The Calculation device [] receives the signals from the US probes and uses their different views to create an image of the flaws within the rail [
