ZWP System Revision

What ZWP System Revision does

ZWP Anlagenrevision GmbH is an accredited non-destructive testing (NDT) laboratory headquartered in Beckingen, Germany, founded in 1975 as ZWP GmbH and operating today as a subsidiary of the TÜV Saarland Group with roughly 30 employees. It specialises in material and infrastructure inspection — principally lighting masts, pipelines, weld seams and industrial plant components — using electromagnetic ultrasonic (EMUS), phased-array ultrasonic, magnetic-flux-leakage and drilling-resistance measurement techniques, with no coupling agents, no radiation protection and no mechanical loading of the asset under test.

The company's product portfolio centres on six proprietary, patent- and brand-protected systems co-developed with the Fraunhofer Institute for Non-Destructive Testing (IZfP) in Saarbrücken since 1990: LIMAtest (mast stability testing with certification valid up to 20 years), CORRfinder (pipeline corrosion detection up to 20m per direction without excavation), PAS-Inspect (phased-array weld inspection replacing radiography in power plants, >15,000 welds inspected since 2009), PIPEflux (corrosion detection below 2mm), BetoFLUX (stress-corrosion-crack detection in concrete-mast prestressing steel) and HOMAtest (wooden-mast drilling-resistance measurement). These feed into LimaDATA, a customer-facing database and mobile app for mast inventory and inspection records. Three additional systems — PiCoInspect, MoniDAQ and Spanndrahtprüfung — are in late-stage development, the last of which extends ZWP into structural-health monitoring of catenary and street-lighting assets.

ZWP operates a pure professional-services revenue model: customers (German municipalities, energy network operators, process-industry and chemical/power-plant operators, and commercial lighting owners) commission inspections on-site or at the Beckingen facility, and the company delivers accredited, digitally documented test reports. The firm runs an enterprise field-sales motion, supported by TÜV Saarland's sales force (north/south Germany) and two regional industrial agencies — TRILUX Vertrieb GmbH and Bernhard Zellmann. Accreditation under DIN EN ISO/IEC 17025 (DAkkS), personnel certification under DIN EN ISO 9712 / ASNT, and ISO 9001:2015 plus SCC** underpin the legal acceptability of its certificates domestically and, via ILAC recognition, internationally.

Core offering

ZWP Anlagenrevision GmbH operates an accredited testing laboratory that performs non-destructive material testing (NDT), primarily using electromagnetic ultrasonic (EMUS) technology co-developed with the Fraunhofer Institute IZfP. The company inspects lighting masts, pipelines, welds, and industrial infrastructure for hidden corrosion, wall-thickness loss, and structural defects, delivering certified inspection reports, static calculations, and stability documentation to municipalities, utilities, and industrial operators.

Product overview

ZWP Anlagenrevision GmbH offers a portfolio of non-destructive testing products and services for infrastructure inspection, centered on electromagnetic ultrasonic (EMUS) technology. The core product line includes LIMAtest for lighting mast stability testing, CORRfinder for pipeline corrosion inspection, BetoFLUX for concrete mast testing, and PIPEflux for pipeline defect detection. Supporting software includes LimaDATA for mast inventory management and EDUSTA (developed with HTW Saarbrücken) for static calculations. The company also offers HOMAtest for wooden mast inspection, PAS-Inspect for phased array weld testing, and comprehensive static calculation and documentation services. Products under development include PiCoInspect for underground pipeline inspection and MoniDAQ for long-term structural health monitoring. The portfolio operates as a complementary ecosystem where testing hardware (LIMAtest, CORRfinder) feeds data into documentation and analysis platforms (LimaDATA, EDUSTA), supported by certification services.
