What is BS EN ISO 30670:2011?

BS EN ISO 30670:2011 is a technical standard established by the British Standards Institution (BSI) and International Organization for Standardization (ISO), which provides guidelines and specifications for the protection of steel pipelines and fittings in corrosive environments. This standard is applicable to both onshore and offshore pipelines used in the oil and gas industry.

Scope and Purpose

The main purpose of BS EN ISO 30670:2011 is to ensure the long-term integrity and reliability of steel pipelines, reducing maintenance costs and minimizing environmental risks associated with corrosion. It sets out the requirements for coating systems to protect against corrosion and other environmental factors that could compromise the performance or safety of the pipeline infrastructure.

Key Requirements

The standard emphasizes the importance of selecting appropriate coating systems based on the specific operating conditions, such as soil type, temperature, humidity, and potential exposure to chemicals. It requires adherence to strict surface preparation procedures to achieve proper adhesion of the coatings and prevent premature failure.

BS EN ISO 30670:2011 also specifies minimum film thickness requirements for different types of coatings, including fusion-bonded epoxy (FBE), liquid epoxy, polyethylene (PE), and polypropylene (PP). These coatings provide excellent resistance to corrosion, impact, and abrasion, ensuring the durability and longevity of the pipeline.

Implementation and Compliance

To meet the requirements of BS EN ISO 30670:2011, pipeline operators are required to establish documented procedures for selecting, applying, and inspecting coating systems. They must also have well-trained personnel who are knowledgeable about the standard and can effectively carry out these processes.

The standard recommends regular inspection and monitoring of the coated pipelines throughout their lifecycle to assess the coating's performance and detect any signs of degradation or damage. If coating failure is detected, appropriate remedial actions should be taken promptly to prevent further deterioration.

Compliance with BS EN ISO 30670:2011 is not only essential for ensuring the integrity of pipeline infrastructure but also for meeting regulatory requirements and achieving industry best practices. It helps enhance safety, environmental protection, and the overall efficiency of the oil and gas industry.
