EN 10298:2005

• Abstract:

  This European Standard specifies requirements for cement mortar linings for protecting the internal surface of steel tubes and pipeline components. It also specifies requirements for their application. It is applicable to the linings of tubes that have been welded longitudinally or spirally, seamless tubes and non-alloy steel components used for fluid transportation. This European Standard does not cover in situ applied or rehabilitation linings.; This type of lining is used in particular in the transport and distribution, under pressure or by gravity, of water intended for human consumption and industrial use, and also in fire extinguishing and waste water systems. The temperature of the water transported should not exceed 50 °C. Higher working temperature can be used by agreement of the parties.; The constituent materials of cement mortar lining, when used under the conditions for which they are designed, in permanent or temporary contact with water intended for human consumption, shall not change the quality of that water to such an extent that it fails to comply with the requirements of European regulations. For this purpose, reference shall be made to the relevant national standards transposing EN standards when available, dealing with the influence of materials on water quality.

Overview

EN 10298:2005 - "Steel tubes and fittings for on shore and offshore pipelines - Internal lining with cement mortar" (CEN) specifies requirements for cement‑mortar internal linings used to protect steel tubes and pipeline components. The standard covers composition, application, inspection and performance requirements for factory‑applied linings on welded (longitudinal or spiral), seamless and non‑alloy steel components used for fluid transportation. It does not cover in‑situ or rehabilitation linings.

Keywords: EN 10298:2005, cement mortar lining, steel tubes, pipeline linings, onshore offshore pipelines, drinking water distribution

Key topics and technical requirements

• Scope & limits
  • Intended for transport/distribution of water (drinking and industrial), fire‑fighting and wastewater systems; normal water temperature ≤ 50 °C (higher by agreement).
  • Material constituents in contact with drinking water must not cause water to fail applicable European/national water quality rules.
• Materials
  • Cement per EN 197‑1 (CEM types shown in the standard); additives allowed (pozzolanic ≤ 10% of cement; non‑pozzolanic ≤ 3%).
  • Sand: controlled particle distribution; fine fraction (<0.125 mm) ≤ 10%; clay/fines ≤ 2%; chloride content ≤ 0.02%; max coarse particle ≤ half minimum lining thickness or 3 mm.
  • Water for mixing: for drinking‑water systems use potable water; for other uses conductivity < 2000 µS/cm and KMnO4 demand < 10 mg/L (or national equivalent).
  • Organic additives must meet saponification resistance (Annex D).
• Application methods
  • Centrifugation (spin casting), spinning‑head, or manual trowelling (repairs/fittings).
  • Surface prep: remove loose rust, scale, oil, debris; light adhesive rust acceptable.
  • Curing and handling requirements to avoid damage and ensure proper strength development.
• Performance metrics
  • Fresh mortar S/C ratio (sand/cement) between 1.0 and 2.5.
  • W/C ratio (water/cement): centrifugation ≤ 0.42; spinning‑head values linked to S/C (e.g., S/C 1.0 → W/C < 0.37).
  • Mechanical: compressive strength ≥ 50 N/mm² and flexural strength ≥ 5 N/mm² after 28 days.
• Purchaser information
  • Orders should specify reference to EN 10298, water type, cut‑back type, pressure/gravity application; optional: cement/additives/method/service temperature/pore sealer.

Applications and practical value

• Used by manufacturers and coaters of internal linings to protect pipelines against corrosion, improve hydraulic performance and ensure potable water safety.
• Common in municipal water distribution, industrial water systems, fire‑fighting mains and gravity or pressurized wastewater lines (factory‑lined pipes and fittings).
• Provides procurement and QA guidance for specifiers, purchasers and inspectors when sourcing lined steel tube systems.

Who uses this standard

• Pipeline designers and engineers, pipe manufacturers, lining contractors (coaters), procurement/specification teams, water utilities, inspection and testing laboratories.
