Strip bend test: Quality assessment of an electrofusion joint

A joint in a plastic piping system made of, for example, polyethylene (PE) must function reliably for many years, often under high pressure and in critical applications such as drinking water and gas networks. Therefore, it is essential to accurately assess the quality of these joints.

FTIR: Identification of (undersired) liquids in gas distribution networks - natural gas condensate

Sometimes liquids occur unintentionally in the gas distribution network. These include, for example, condensed gases from the gas network, often referred to as ‘natural gas condensate’. Liquids in the gas network can be harmful to both human health and the environment. Therefore, correct procedures for removing these liquids are essential. The procedures depend on the type of liquid, which cannot always be determined by visual inspection. Fortunately, there is a solution: infrared spectroscopy (FTIR). This measurement method makes it possible to identify the type of liquid.

Kiwa conducts decarbonization scan for Vitens Spannenburg site

At the request of Dutch drinking water company Vitens, Kiwa conducted an energy and decarbonization scan for Spannenburg, the largest drinking water production site in the Netherlands. The scan provides insight into Spannenburg’s energy consumption and explores possible measures to make the site more sustainable. The results provide building blocks for further steps towards reducing CO2 emissions.

Research into the vulnerability of data cables during manual digging

The energy transition is leading to a growing need for excavation work in the Netherlands. The installation, replacement and reinforcement of cables and pipelines increasingly requires work to be carried out underground. Careful excavation is essential, as damage to data cables can disrupt internet, television and telephone services, causing inconvenience for users and costs for companies and society.

Kiwa wins international award for innovative methane reporting

Kiwa, together with Alliander, DEP and Stedin, has won the IGU Global Gas Award during the 29th World Gas Conference (WGC2025) in Beijing. The award was granted for the paper ‘OGMP 2.0 Methane Emissions Reporting: The Dutch Approach’.

The road to a new detergent for the Accelerated Notched Pipe Test (ANPT)

The Accelerated Notched Pipe Test (ANPT) plays a crucial role in assessing the resistance of polyethylene (PE) pipes to slow crack growth, because it mimics real-world installation damage. However, recent restrictions on the detergent Arkopal N100, traditionally used in the test, have posed challenges for compliance with international standards. This article explores the search for a more sustainable alternative detergent, with Kiwa Technology at the forefront of these developments.
