(Main)Steel tubes and fittings for on and offshore pipelines - Internal coating for the reduction of friction for conveyance of non corrosive gas
General Information
- Abstract
This European Standard specifies the application requirements and methods of test of liquid applied epoxy paints on the internal surface for the reduction of friction of tubes and pipeline fittings for conveyance of non-corrosive gas.
Other paints or paint systems are not excluded provided they comply with the requirements given in this standard.
The coating consist of one layer of liquid product, normally shop applied onto abrasive blast cleaned steel by airless spray or conventional spray techniques. Brush application may be used only for repairs.
The coating qualified in accordance with this standard is considered suitable for operating temperatures between
- 20 °C and + 110 °C.
In this European Standard the word "components" is used for tubes and fittings.

Overview
EN 10301:2003 is a CEN European Standard for internal coatings of steel tubes and fittings used in onshore and offshore pipelines that convey non‑corrosive gas. The standard specifies the application requirements and test methods for liquid‑applied epoxy paints intended primarily to reduce internal friction (hydraulic drag) in pipeline components. The coating is normally a single, shop‑applied liquid layer laid onto abrasive blast‑cleaned steel by airless or conventional spray; brush application is permitted only for repairs. Coatings qualified to EN 10301:2003 are suitable for service temperatures between –20 °C and +110 °C.
Key Topics and Requirements
- Coating type: Liquid applied epoxy paints (other systems allowed if they meet the standard).
- Application: One layer; shop application by airless or conventional spray; brush only for repairs.
- Surface preparation: Abrasive blast cleaning of steel prior to coating.
- Temperature range: Qualified coatings suitable from –20 °C to +110 °C.
- Qualification and testing: Detailed test regime and acceptance criteria, including:
- Physical properties: non‑volatile matter, viscosity, density, pot‑life, appearance.
- Film properties: dry film thickness (DFT), adhesion (cross‑cut), Buchholz hardness, porosity.
- Durability tests: resistance to neutral salt spray, ageing, water immersion, chemical resistance.
- Mechanical performance: bend (conical mandrel) test, resistance to gas pressure variation, hydraulic blistering.
- Analytical checks: ash content, infrared analysis.
- Inspection & documentation: Sampling, frequency of testing, technical documentation, packaging, marking, storage, handling and repair procedures are covered.
Applications and Who Uses This Standard
EN 10301:2003 is used by stakeholders involved in pipeline design, manufacture, installation and operation where friction reduction inside steel pipelines is required for non‑corrosive gas services. Typical users:
- Pipeline manufacturers and fabricators (tubes and fittings)
- Coating material suppliers and applicators (shop applicators)
- Pipeline engineering and design teams focusing on flow efficiency
- Inspection and quality control personnel (testing and acceptance)
- Asset owners, operators and procurement teams specifying coatings for new builds or replacements
Practical benefits include lower frictional losses, improved hydraulic efficiency and standardized qualification/acceptance procedures for internal epoxy coatings in gas pipeline systems.
Related Standards
EN 10301 references several EN/ISO test standards used for coating evaluation and measurement, for example:
