Probe for fast corrosion imaging Non-destructive testing technologies specialist Olympus has introduced its new Dual Linear Array probe, designed to improve the inspection of internally corroded parts such as pipes, tanks and plates. The phased array solution improves productivity through features such as larger beam coverage, faster scan speed, and C-scan imaging with increased data-point density.

Its compact, lightweight aluminium housing provides easy handling and operation, while carbide wear plates protect the wedges for increased durability. The probe adds a new entry-level inspection capability to the existing Olympus HydroFORM ® and RexoFORM corrosion solutions, especially when combined with the OmniScan ® SX. When using the probe with an OmniScan phased array instrument, the setup and operation is simple: load the setup file and check the calibration, then inspect and record the data. Olympus Scientific Solutions Americas, a subsidiary of Olympus Corporation, has specific responsibility for the sales and marketing of life science and industrial instrumentation in the Americas. The company’s core product line-up offers clinical, educational and research microscopes, non-destructive testing equipment, and analytical instruments.

The pitch-catch technique used by the new probe is claimed to offer better near-surface resolution and pit detection in corrosion survey applications than standard phased array pulse-echo, improving probability of detection of critical wall thinning.

The Dual Linear Array probe provides the inspector with several claimed advantages over conventional ultrasonic dual element transducers that are typically used with flaw detectors.

Root-inhibiting drain pipe adhesive T Christy Enterprises has launched a drain pipe adhesive that seals joints and prevents root intrusion in underground drainage pipe.

drain pipe joints. The seal is both watertight and flexible, so pipes are less susceptible to shifting and separation. This eliminates seepage or leaks that attract roots and root intrusion into joints. The adhesive is the result of an 18-month development conducted at the company’s labs. The development effort partnered construction professionals with the company’s R&D team to identify solutions for root intrusion into drainage pipe joints.

a seal that is many times stronger than the commonly used press-fit method. The active ingredients in Root-Ban have been proven to remain active throughout the life of the drainage system. This saves time, money and – most important – the hassle of chemical and mechanical root removal or excavation and replacement of the entire drainage system.” Roots typically enter drain lines through poorly protected push-fit pipe connections, which are often not watertight. The roots quickly fill up the drainage pipe, impeding water flow and causing premature system failure.

The patent-pending Root-Ban™ drain pipe adhesive contains a proprietary chemical formulation that creates a leak-proof seal. The dual action formulation contains ingredients that seal the pipe and cause roots to avoid contact with the pipe. The roots grow around the pipe and not into the joint. “Root intrusion is the number one cause of drainage system failure,” said Laura Poston, T Christy director of marketing. “Root-Ban drain pipe adhesive creates
