Anchoring solutions for the NATURAL range - DN 60 to 600
The NATURAL ductile iron pipeline range comprises:
- Pipes :
With 400 g/m2 external coatings of 400 zinc (85%) and aluminum (15%) alloy and a coat of light blue epoxy.
Pressure class C40, DN 60 to 300, and C30, DN 350 to 600, with STANDARD joint.
Pressure class C30 DN 700 to 1000, and C25 DN 1200 to 1600 with UNIVERSAL joint.
- Fittings :
With EXPRESS and STANDARD joints with epoxy coating deposited by cataphoresis (in compliance with EN 545).
With STANDARD or UNIVERSAL joints with epoxy powder coating (in compliance with EN 14901).
The NATURAL range's durability and scope of use are considerably greater than those of cast iron pipelines with only a 130 g/m2 zinc coating as prescribed by standard EN 545.
The anchoring solutions in the NATURAL range
STANDARD Vi and EXPRESS Vi – For most common situations
STANDARD Vi for pipes, DN 60 to 600 and STANDARD fittings, DN 350 to 600.
EXPRESS Vi for fittings, DN 60 to 300.
UNIVERSAL Vi – For very high pressures
For UNIVERSAL pipes and fittings, DN 80 to 600.
UNIVERSAL Ve – For extreme pressures
For UNIVERSAL pipes and fittings, DN 100 to 600.
For aggressive situations, the following pipeline :
TT for aggressive soils
Suitable for very corrosive soils or when there are stray currents (See standard EN 545 appendix D.2 to check when it is advisable to use this external coating).
The STANDARD TT-PE solution has a thick extruded polyethylene coating in accordance with European standard EN 14628. This is the most commonly used solution in this range.
NATURAL PUR for aggressive water
Suitable to carry water that is aggressive to cement mortars (See standard EN 545 appendix E to check when it is advisable to use this internal coating).
The PUR solution has an internal polyurethane coating in accordance with standard EN 15655.

Important supplementary information
Angular deflection
Ensure compliance with the maximum angular deflection specified in the table, and note the angular deflection of anchored joints is generally slightly less than that of joints that are not anchored.
Fittings
UNIVERSAL fittings are not available in DN 350 and 450. STANDARD V+I anchoring fittings should be used with UNIVERSAL Vi pipes, and STANDARD Ve fittings should be used with UNIVERSAL Ve pipes in these 2 DN.
Combined use of NATURAL STANDARD and NATURAL UNIVERSAL pipes
When performing cutting operations on site, be sure to distinguish cuts performed on UNIVERSAL pipes from cuts made on STANDARD pipes (by applying paint to mark cuts on UNIVERSAL pipes, for example). Only UNIVERSAL cut sections can be fitted in UNIVERSAL sockets with the anchoring pressure levels specified in the table.
