Installation instructions 11.Installation instructions 11.1 General Applicability These installation instructions apply to DN 80 - DN 00 ductile cast iron pipes and fittings with longitudinal force-fit BLS ® restrained joints. Where appropriate the installation instructions for pipes with cement mortar coatings (ZMU) should be followed. For very high internal pressures (e.g. in snow making facilities) and for trenchless installation techniques (e.g. the press-pull, rocket plough or horizontal directional drilling techniques) an additional high-pressure lock has to be used (see section headed „Highpressure lock“). In the case of buried pipelines, the number of joints to be locked has to be decided in accordance with DVGW Arbeitsblatt GW 3 8. The permitted tractive forces for trenchless installation techniques are laid down in DVGW Arbeitsblätter GW 321, 322-1, 323 and 32 (draft), or see section 2, page 20. Bundling, transport and storage Pipes of up to DN 3 0 size are supplied bundled 102 DN Pipes 80 100 12 1 0 200 2 0 300 3 0 per bundle 1 1 10 To stop the pipes from being damaged or fouled, wooden supporting timbers and spacing blocks should be used both when the pipes are being stored temporarily and when they are being laid out along the run. The steel straps holding the bundles of pipes together must only be removed with tinsnips or side cutters. Chisels, crowbars and certainly pickaxes will damage the outside protection that the pipes have.
