Hydrogen Distribution

In response to the social and industrial focus on sustainable energy sources, GF Piping Systems has already taken steps to future-proof its range of products. Our comprehensive piping components are suitable for 100% hydrogen approved by KIWA (AR214). 

In addition to that, we are proud to share our approvals for ELGEF Plus and WAGA products being 100% H2 ready tested by DBI Gastechnologisches Institut in Leipzig, Germany. Our products have been preemptively designed and tested to meet stringent international standards, ensuring they are ready for immediate deployment once local regulations are in place. This proactive approach ensures that our clients can quickly adapt to new regulatory environments without compromising on safety or performance.

DBI and KIWA have conducted extensive tests on our products, including pressure testing, leak testing, and material compatibility assessments. These tests ensure that our products can safely and effectively handle hydrogen under various conditions. The rigorous testing protocols verify that our piping systems maintain integrity, prevent leaks, and resist the specific challenges posed by hydrogen, such as embrittlement and permeation.

Transporting hydrogen is challenging due to its low density, high diffusivity, and potential for embrittlement in metallic pipelines. GF Piping Systems’ products, made from alternative materials like polyethylene, offer solutions to these challenges by providing secure, leak-proof, and durable piping systems that are resistant to hydrogen embrittlement and permeation. Our polymer piping solutions are designed to mitigate these risks, ensuring safe and efficient hydrogen transport.

Standards Followed by KIWA Certification
KIWA is an independent organization renowned for its across various industries, including water, energy, and construction. To ensure compliance with KIWA certification for hydrogen distribution, the following standards must be followed:

1. GASTEC QA Approval Requirement 214: This standard ensures the fitness of materials and components for admixtures up to and including 100% hydrogen gas. It is crucial for verifying that the materials used can safely handle pure hydrogen as well as hydrogen blends.

2. GASTEC QA Approval Requirement 200: This basic certificate pertains to electrofusion fittings and saddles made from polyethylene (PE). It ensures that these components meet the necessary quality and safety standards for use in gas distribution networks.

KIWA’s certification process involves comprehensive assessments of product performance, material integrity, and adherence to these international standards. Their certifications provide assurance that products meet the highest safety and quality benchmarks for hydrogen applications.

DBI (Gas Technology Institute in Leipzig, Germany) specializes in testing and certification for gas technology and related infrastructure, including hydrogen applications. To ensure compliance with DBI certification for hydrogen distribution, the following standards must be followed:

1. DBI-GTI 108: This standard involves testing for H2 readiness for fittings made of polyethylene (PE). It ensures that the fittings are capable of safely handling hydrogen gas without degradation or failure.

2. DBI-GTI 106: This standard pertains to testing for H2 readiness for shut-off valves made of PE. It verifies that the shut-off valves can operate reliably and safely in hydrogen gas environments.

3. DVGW GW 335: This basic certification covers plastic piping systems in gas and water distribution. Specifically, Part B2 focuses on fittings made of PE 80 and PE 100. It sets the requirements and tests to ensure the quality and safety of these fittings for use in gas distribution networks.

DBI conducts rigorous testing according to these standards, evaluating factors like pressure resistance, leak tightness, and resistance to hydrogen embrittlement. Their certifications validate that products are suitable for use in hydrogen environments and comply with stringent regulatory requirements.
