NDT for Industrial Piping in Belgium

Comprehensive non-destructive testing services for industrial piping systems — from fabrication inspection to in-service corrosion monitoring. LCNDTEST operates throughout Belgium and across Europe.

Non-Destructive Testing for Piping Systems

Industrial piping is one of the most critical components in any process installation. Whether transporting steam, hydrocarbons, chemicals or compressed gases, piping systems operate under demanding conditions of pressure, temperature and corrosive exposure that can progressively degrade material integrity. A single undetected defect in a welded joint or a localised thinning caused by internal corrosion can lead to catastrophic failure, resulting in production shutdowns, environmental contamination and, most critically, risks to personnel safety.

LCNDTEST, based in Nivelles in the heart of Walloon Brabant, provides a full range of non-destructive testing services specifically tailored to the inspection of industrial piping systems. Our certified technicians operate on new fabrication projects, during planned maintenance shutdowns and on in-service installations across Belgium — from the petrochemical complexes of Antwerp to the industrial zones of Charleroi, Liege and Brussels. We inspect piping in accordance with the most demanding international codes including EN 13480, ASME B31.1, ASME B31.3, API 570 and the requirements of the Pressure Equipment Directive (PED 2014/68/EU).

Our approach combines multiple NDT methods to deliver a thorough assessment of piping integrity, ensuring that every weld, fitting and straight run meets the required quality and safety standards. Whether you require pre-service inspection of a newly fabricated spool, in-service corrosion monitoring of an ageing process line, or a comprehensive piping inspection programme during a plant turnaround, LCNDTEST has the expertise, equipment and certifications to deliver reliable, actionable results.

Adapted Inspection Methods

The inspection of industrial piping demands a carefully selected combination of NDT methods, chosen according to the material type, wall thickness, service conditions, defect types sought and the applicable code requirements. LCNDTEST deploys a comprehensive range of techniques to address every piping inspection scenario, from thin-wall stainless steel process lines to heavy-wall carbon steel headers operating at high pressure and temperature.
  • Visual Testing (VT) for systematic examination of weld appearance, alignment, surface condition and evidence of corrosion or mechanical damage — the essential first step of any piping inspection programme
  • Ultrasonic Thickness Measurement for corrosion mapping, residual wall thickness assessment and remaining life calculation on in-service piping in accordance with API 570 and API 574
  • Radiographic Testing (RT) using film or digital techniques for volumetric inspection of circumferential and longitudinal butt welds during fabrication and in-service examination
  • Ultrasonic Testing (UT) including conventional, TOFD and Phased Array techniques for weld inspection, detection of internal defects and precise defect sizing on critical piping welds
  • Magnetic Particle Testing (MT) for the detection of surface and near-surface cracks on ferritic steel piping, particularly at stress concentration points such as nozzle connections, branch welds and support attachment areas
  • Penetrant Testing (PT) for the detection of surface-breaking defects on austenitic stainless steel and non-ferrous alloy piping where magnetic methods are not applicable
  • Positive Material Identification (PMI) using portable XRF to verify the alloy grade of piping components, fittings, flanges and welds — essential for preventing material mix-ups in critical service applications
  • Hardness Testing on welds and heat-affected zones to verify post-weld heat treatment effectiveness and compliance with maximum hardness requirements specified by the design code

Standards and Regulations

All piping inspections performed by LCNDTEST comply with the applicable European and international standards and codes. For new fabrication, we inspect in accordance with EN 13480 (metallic industrial piping), ASME B31.1 (power piping) and ASME B31.3 (process piping), as well as the requirements of the PED 2014/68/EU for pressure-retaining components. For in-service piping, our inspection programmes follow the guidelines of API 570 (piping inspection code), API 574 (inspection practices for piping system components), and fitness-for-service assessments are conducted in accordance with API 579-1/ASME FFS-1. Our technicians are certified to EN ISO 9712 Level 2 and Level 3, ensuring competent and reliable interpretation of inspection results.

Frequently asked questions

The most commonly applied methods for piping inspection are visual testing (VT), ultrasonic thickness measurement for corrosion monitoring, radiographic testing (RT) for weld inspection during fabrication, and ultrasonic testing (UT) for both weld examination and wall thickness assessment. The specific combination of methods depends on the piping material, service conditions, applicable code requirements and whether the inspection is performed during fabrication or in service. LCNDTEST systematically recommends an optimised inspection plan tailored to your piping system and regulatory obligations.

Inspection frequency for in-service piping is determined by several factors including the corrosion rate, operating conditions, consequence of failure and the requirements of the applicable inspection code (typically API 570 in the petrochemical industry or Belgian regulatory requirements for pressure equipment). High-risk piping circuits with elevated corrosion rates may require annual inspection, while low-risk systems operating in benign conditions may be inspected on a longer interval. LCNDTEST assists clients in establishing risk-based inspection programmes that optimise inspection frequency while ensuring regulatory compliance and safe operation.

Yes, many piping inspection techniques can be performed while the installation remains in operation. Ultrasonic thickness measurement, for example, can be carried out on in-service piping, including at elevated temperatures using specialised high-temperature probes. External visual inspection and certain magnetic particle testing applications can also be performed during operation. However, internal inspection and some weld examination methods (such as radiographic testing) typically require the piping to be taken out of service and isolated. LCNDTEST works with our clients to plan inspection campaigns that minimise production impact, combining on-stream techniques during operation with more comprehensive examinations during planned shutdowns.
