1.1 Area of Application
The Moore GmbH company offer pressure pipes made of PE 80 and PE 100 for gas supply, drinking water supply and waste water disposal. When Moore pressure pipes made of PE 80 and PE 100 are laid in a sand bed in accordance with the applicable installation instructions and the prescribed conditions of operation are observed, then operating lifetimes of 100 years can be predicted.
1.2 Form of Delivery
Moore pressure pipes made of PE 80 and PE 100 can be delivered with outer diameter of 20 to 125 mm. With outer diameters of up to 75 mm, the pressure pipes can be delivered on rods of length 6m or 12m, as well as in coiled bundles of 25m, 50m and 100m, with other lengths possible upon request. The dimensions 90 - 110 mm are deliverable on rods of length 6m or 12m and as coiled bundle of 100m. With outer diameter 125mm, only rods of lengths 6m and 12m are delivered, due to problems with transport.
1.3 Colours and Dimensions
Pressure pipes of PE 80 and PE 100 are manufactured in accordance with the dimensions and tolerances of DIN 8074. Adherence of dimensions and tolerances to this standard is checked continually in the Moore company’s factory internal quality assurance process.
Moore pressure pipes made of PE 80 and PE 100 are certified by the DVGW.
DVGW-certification number: DG –8106BO612
1.5 Connection Technology
Moore pipes of PE 80 and PE 100 can be connected with all welding procedures which have been certified for polyethylene. Since the pipes conform to DIN 8074 in their dimensions and tolerances for outer diameters and wall thicknesses, all mechanical connection methods for PE pipes can likewise be used.
1.5.1 Heating Element Butt Welds
This connection technology is used primarily for larger nominal diameters. Because of the limited pipe wall offset in the DVS guideline 2207, the Moore company can only recommend this welding technology for wall thicknesses of at least 10mm. Heating element butt welds are used to create a homogeneous weld in respect to materials without additional use of materials. The surfaces to be connected are levelled with a plane and then aligned under pressure at the heating element and heated. When the surfaces have heated through, the heating element is removed and the welding surfaces are joined. During cooling, the joining pressure of the parts clamped in the welding slide must be maintained. It is not permissible to take any measures to accelerate cooling of the welded parts.
1.5.2 Heating Coil Welds
With this procedure the pipe's exterior surface and the inner side of the fitting are heated up by an electric current through resistance wires in the fitting. The coordinated tolerances between the pipe and the fitting lead to formation of a melting pressure in the connecting surface, and this leads to a homogeneous weld. The supply of electric current at the fitting and the prescribed welding times are read by the welding machine from a bar code on the fitting and then processed further. With this fully automatic welding procedure, the control unit automatically registers temperature influences and takes these into account. With most welding machines, the parameters of the entire welding procedure are automatically stored and can be printed at the end of the job. In addition, DVS guideline 2207 T1 contains comments on this welding procedure which have to be observed.
This connection technology is especially suitable when space is restricted, for repairs and for small pipe diameters.
1.6 Requirements on Laying Cables
All work on laying pipes for drinking water may only be carried out by pipe companies which have a DVGW certificate pursuant to DVGW work sheet GW 301 "Procedures for Granting DVGW Certificates for Pipe Construction Companies". All persons employed to carry out such construction work must be trained in accordance with DVGW sheet GW 330 "PE welders; schooling and test plan". The work is to be monitored by a welding supervisor in accordance with DVGW sheet GW 331 "PE welding supervision; schooling and test plan". The accident prevention regulations (UVV) of the appropriate professional associations are to be adhered to.
For activities within public traffic areas, the German Street Traffic Ordinance is of special importance. In particular, the guidelines for cordoning off work sites on streets (RSA) must be observed.
When construction work is commissioned in accordance with VOB, the VOB/C "General Technical Contractual Conditions for Construction Services" is to be applied.
