High-quality butt fusion welds
What is NEN 7200?
NEN 7200 is the Dutch standard for welding PE pipes and fittings. It sets requirements for butt fusion welds, a technique where two PE ends are welded together using heat and pressure. Since its 2017 revision, the standard reflects current safety requirements and quality standards.
Why choose NEN 7200 certification?
Although NEN 7200 is not legally required, certification offers clear benefits:
Demonstrate that your welds meet the highest quality and safety standards
Minimise risks of leaks and failures in piping systems
Show proven compliance with applicable norms and regulations
Increase your reliability towards clients and regulators
Strengthen your competitive position in tenders and collaborations
Prove that you continuously test and improve your processes
Why was NEN 7200 developed?
EN 7200 was developed to ensure the quality, safety, and reliability of welds in PE piping systems. The standard provides guidance for the construction, inspection, and improvement of butt fusion welds. Companies working according to NEN 7200 demonstrate compliance with legislation and standardised welding procedures, facilitating cooperation with contractors, installers, and inspectors.
In which sectors is NEN 7200 important?
The standard is essential for sectors using PE piping, such as:
Gas distribution (safe transport of gas)
Drinking water companies (preventing leaks and contamination)
Industry and telecommunications (reliable infrastructure)
What does NEN 7200 mean for your company?
With NEN 7200 certification, you prove that your work is of high quality and safe. Partners and clients can see that you comply with the latest regulations and continuously invest in quality. This strengthens your competitive position and builds customer trust.
The impact of NEN 7200 on quality
The standard ensures the standardisation of PE welds. This minimises leakage risks and improves safety. Uniform procedures allow for better cooperation between parties, increasing overall project safety. NEN 7200 is also a continuous process: companies must consistently demonstrate compliance with the highest standards, supported by documentation and audits.
