Element’s pipeline and field-joint coatings services help you determine the performance of suitable pipeline coating protection materials to ensure your entire pipeline, or subsea production structure resists corrosion and can withstand extreme environmental and service conditions throughout its design life. Testing is carried out to widely recognized International and National standards such as ISO 21809 pts 1-3.
Field-joint coatings are applied on offshore lay vessels where offshore pipelines are welded together in either single or double joint segments. Exposure in a hostile environment and vulnerable to corrosion, the welded area is often the weakest point within a pipeline. It is critical to select a suitable material used to protect the field joint.
Pipeline and field joint coatings standards
Element provides field-joint testing services to offshore and onshore pipeline customers in accordance with the primary industry-standard ISO 21809. Our expertise encompasses a variety of test methodologies, including holiday detection, peel strength, adhesion testing, water immersion, lap shear resistance, cathodic disbondment, impact resistance, indentation resistance, and flexibility.
Our ISO 21809 test procedures
We conduct testing throughout the pipeline project process, including PQT and PPT qualifications:
- Application procedure specification
- Pre-qualification trial
- Pre-production trial
- Inspection and testing plan
- Quality assurance versus quality control
