Features
Easy pull-in of the carrier pipe The spacer's friction coefficient is reduced to a minimum because they are made of plastic The minimized friction prevents damage to the protective coating and wrapping of the pipes A wide range of skid heights facilitates the centering/storage of carrier pipe in casing pipe Excellent insulating properties of the materials used. All requirements of cathodic pipe protection are fulfilledAreas of application
Casing spacers made of high-quality polypropylene material are universally applicable in the installation of all kinds of pipelines when the carrier pipe runs through a casing pipe.Description
Polypropylene has a waxy and therefore a good sliding surface. The coefficient of sliding friction of PP on steel is approx. 0.2. In comparison, steel on steel is about 0.5. Due to the optimum friction conditions, abrasion is reduced to a minimum. Good stress cracking resistance, flexibility of the body, low weight, bending stiffness and stability of the skids form as well as excellent dielectric isolation characteristics are further benefiting properties. Polypropylene has a higher temperature resistance than polyethylene. The base material is resistant up to 100 °C. The specification of the load capacity applies for a skid height up to 75 mm. For skid heights above 75 mm, these values shall be multiplied by a factor of 0,75. These specifications apply to standard pipelines. To determine the correct distances for an individual application, other factors have to be taken into consideration, such as pipe diameter, wall thickness of pipe and type of media (gas or liquid). We will be glad to assist you in determining the exact dimensions.Assembly Instructions
| 1 | Put out spacer elements and wedges according to selection table. Connect elements as a spacer band (for position of the wedges per spacer element see selection table on the backside), put the mounting link with grid into the entry of next element, be aware of parallelism. Push wedges into the lateral fixing slot until top can be seen on the other side of the spacer. Mind the direction of the arrows. |
| 2 | On smooth pipe surface which are in contact with the spacers (e.g. PE, PVC, steel/cast on PE-coated or stoneware) wrap a shear-secure-tape to guarantee an optimum security against slipping. |
| 3 | Put pre-mounted elements around the medium pipe and close last joint. Shift the spacer ring together by hand. |
| 5 | Drive in all wedges with rubber hammer strokes parallel to the pipe. The wedges don’t have to be in fully. |
| ! | For a pipe O.D. 429 mm, use 3 full and 1 half element per ring. Put 1 wedge in position 1 and 3 wedges in position 2. |
| Attention | When mounting more spacer rings please be aware that the skids of the single mounted rings align together. |
