Fig. 5-13 Cell current in a pipe with cement-mortar lining anode is an uncoated ring, tapwater at 15°C. Fig. 5-13 Cell current in a pipe with cement-mortar lining anode is an uncoated ring, tapwater at 15°C.
Figiue 4.15 shows the basic structure of cement-based materials, exemplified by a cement-mortar lining. The binder consists of hydrated cement produced by reacting water with anhydrous cement, which contains calcimn silicates and calcium aluminates in various proportions. [Pg.156]

Generally, concrete used for water treatment plant pipes, water tanks, and filters is made using (ordinary) Portland cement, whereas cement-mortar linings can be made of diflerent types of cements, such as Portland cements, blast furnace cement or the non-Portland calcium aluminate cement. Each type of cement has a typical composition. Table 4.14 gives the typical composition of the primary cements used for manufacturing pipe. [Pg.157]

External and internal corrosion resistance of the pipe material itself and the sealing material or the external and/or internal corrosion protection External corrosion protection according to DIN 30674, Part 3 or Part 1, 2 or 5. Internal corrosion protection with cement mortar lining according to DIN 2614 or with a special lining. [Pg.297]

Maintenance suitability Investigations with respect to the influence of high-pressure water sprays on the cement mortar lining of the ductile cast-iron pipes showed that there was no damage caused by commonly used nozzle heads and flushing pressures up to 170 bar. [Pg.298]

It is recommended to use ductile (nodular) cast iron instead of gray cast iron (brittle). Ductile iron pipe with a cement mortar lining has given excellent performance. [Pg.51]
