Tank and Piping Inspection
|
York River NDE, Inc. offers comprehensive tank inspections, both in service and out of service which meet or exceed, the requirements established in API 653 or STI 001. Ultrasonic thickness data of the steel shell and roof plate can be acquired by conventional methods or by an automated magnetic ultrasonic crawler which is especially good for locating shell thinning at the vapor zone (air liquid interface). Tank floors are scanned using the LFET method (Low Frequency Electromagnetic Testing} to locate under bottom corrosion ,followed by ultrasonic thickness measurement to verify and access any questionable low areas.
York River NDE utilizes the Scantech Instruments, Inc. extremely maneuverable, remotely operated C1 Spider Crawler for ultrasonic corrosion testing of storage tanks, walls and roofs to determine the remaining thickness. This unit is attached to the steel plate by four driven, high strength, rare earth magnetic wheels, coupled with a flexible suspension and two high torque motors this crawler can easily transverse weld seams.
This system is used for continuous encoded B-scan measurements using "Analyst" Data Acquisition and reporting software.
Ultrasonic thickness and visual inspections are performed on shell and roof penetrations as access allows. Visual inspections are conducted on all attachments both internal and external to the shell such as access ladders, piping supports , agitator mounts and platforms where applicable to the type of inspection being conducted.
York River NDE, Inc. offers multiple services in determining the quality and integrity of your piping systems. API-570 piping inspections accurately explain the mechanical integrity of each piping system. You will receive a detailed report that includes drawings, photographs, and the calculated life expectancy of the remaining material. This inspection satisfies the requirement of OSHA's Process Safety Management and can be used as part of your predictive maintenance program.
In addition to the normal piping system thickness report, detailed information is included on the condition of support structures, coating and insulation condition as these items apply.
York River NDE, Inc., also can perform ultrasonic leak detection of both pressure and vacuum process piping and duct work. Ultrasonic leak detection is the preferred method for the detection of leaks in pneumatic, hydraulic and liquid transport piping and lines.
