Organic coating systems and linings for protection of industrial apparatus and plants against corrosion caused by aggressive media - Part 6: Combined linings with tile and brick layers
This European Standard describes the requirements for and methods of testing of combined systems with tile and brick layers which are applied to concrete or metallic process engineering equipment that will come in contact with chemical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of quality control (e.g. as agreed between the contract partners or having been given by national regulations )).
The standard applies to systems which serve one or more of the following purposes:
- to protect the component from adverse effects of aggressive substances;
- to protect waters (e.g. ground water) against hazardous substances;
- to protect the charge from becoming contaminated by components released from the substrate material;
- to achieve a particular surface quality.
The described combined systems can be used for concrete or metallic process engineering equipment that will come into contact with chemical substances.
The combined system is a combination of:
- a coating according to EN 14879-2 or EN 14879-3 with an additional layer of tiles or bricks embedded in cement mortar, resin based mortar and/or potassium silicate mortar as an adhesive bonding cement (re-ferred to simply as cement in this standard); or
- a lining according to EN 14879-4 or EN 14879-5 with an additional layer of tiles or bricks embedded in cement mortar, resin based mortar and/or potassium silicate mortar as an adhesive bonding cement (re-ferred to simply as cement in this standard).

Brick-lined vessels which are operated by heat and/or pressure shall be designed on the basis of principles that go beyond the requirements for pressure vessels, account being taken of the following: SIST EN 14879-6:2010
Flat surfaces present problems with respect to brick linings. They shall therefore: a) be kept as small as possible; b) be strongly reinforced against bending; c) be designed so as to have flexural strength at the corners; d) have a retaining point for the brickwork on the free edge, if necessary (see Figure 2); e) be designed with an inclination ≥ 2 % if necessary.
Figure 2 — Flat plate wall Base and lateral supports shall only be fitted where absolutely necessary. If vessel covers are to be brick-lined they shall be curved and have a support for the lining. SIST EN 14879-6:2010
Environmental and/or safety requirements are to be observed. 4.1.5 Leak tests All vessels shall be leak-tested before being brick-lined. 4.1.6 Repairs and modifications If brick-lined vessels require welding, the brick lining within a reasonable distance of the weld point shall be removed before welding takes place. The regulations that apply to brick-lined vessels shall also be observed. 4.2 Concrete vessels and apparatus 4.2.1 Calculating the dimensions of brick-lined concrete vessels Dimensions of the vessels to be brick-lined are to be statically calculated so that the structural deformations are limited in such a way that no possibility of damages in the brick lining can occur. Here special attention should be paid to reduce cracks in the concrete, in relation to the sealing layer to be used. With consideration of thickness and elasticity of the sealing layer, the width of cracks in the concrete must be limited to 0,1 mm to 0,3 mm. The reinforcement is to be laid out in accordance with EN 206-1. When calculating and executing the concrete structure the operating temperature and pressure and the possible swelling of the brick lining should be considered. Damaging tensile strengths shall be avoided. The properties of the materials should be taken from the manufacturer’s specifications. Typical values are given in 4.5. In case of higher temperatures and/or excess pressure a tensile appraisal will become necessary. Practical references can be applied. 4.2.2 Dimensional tolerances
At this time no regulated specifications exist. Admissible deviations shall be agreed with the manufacturer of the brick lining. 4.2.3 Requirements to the concrete construction Requirements to the concrete construction and surface shall be in accordance to EN 14879-1. 4.3 Substrate preparation For preparation of substrate see EN 14879-1. 4.4 Sealing layer The sealing layer shall be either a coating according to EN 14879-2 and/or EN 14879-3 or a lining according to EN 14879-4 and/or EN 14879-5. The sealing layer of a combined lining system serves as a sealing of the component and crack bridging of the concrete. Since in most cases the service layer also protects the sealing layer from direct exposure to chemi-cal, mechanical or thermal loads, the suitability may only be determined by testing the system as a whole. Taking into consideration the particular requirement and the expected life the combination of sealing layer and service layer that has the best all-around resistance shall be selected. As a rule, the system shall be designed either for the expected loads or (in special cases) for higher loads than expected. SIST EN 14879-6:2010
The mortar used shall be selected on the basis of the expected loading, taking the load profile according to 4.7.1 to 4.7.5 and the following requirements into consideration. SIST EN 14879-6:2010
bitumen, shall especially be considered. c) Thermal stability The mortar shall be resistant to any expected thermal loads. Especially to be considered are the maximum and minimum temperatures to which the mortar will be exposed, the duration of exposure, and the speed and frequency of any temperature changes. d) Shrinkage While hardening, mortar shrinks to an extent which depends on its specific material properties. In combined lining systems, this shrinkage and any changes in length are hindered, resulting in shrinkage stress. The mor-tar used shall form a solid bond with the sealing layer and tiles or bricks in the service layer. Additional meas-ures such as sanding, keying or priming may be used to improve adhesion. There shall be no cavities or cracks in the service layer. Shrinkages can be reduced by using for example thicker tiles or bricks. e) Capability of dissipating electrostatic charges If necessary, the resin based mortar's conductivity may be increased by adding suitable materials (e.g. carbon fillers). The dissipation resistance is tested according to Annex C (normative) with a measuring voltage of 100 V. The insulation resistance (surface resistance) is measured according to IEC 60167 with 100 V DC voltages. EN 1081 may still be used. 4.5.1.2 Materials 4.5.1.2.1 General The following materials may be used for bedding and jointing: a) cement mortar; b) potassium silicate mortar; c) bituminous compounds; d) resin-based mortars (e.g. based on epoxy (EP), furan (FU), phenol formaldehyde (PF), unsaturated poly-ester (UP), or vinyl ester (VE)). Table 1 presents the general characteristics of cement mortar, potassium silicate mortar and bituminous com-pounds. The general characteristics of the resin-based cement are presented in Table 2.
