| Description | The variable number of segments ensures that the spacer can be adapted to the different carrier pipe diameters |
| Plastic spacers are usually installed with the following distances: Pipe diameter up to 300 mm at 2.5 m distance Pipe diameter 301 - 600 mm at 2.0 m distance Pipe diameter larger than 600 mm at 1.5 m distance The spans also depend on the specifications of the respective pipe manufacturers. In particular cases, the ring distance can be modified after checking the installation situation. |

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 | Get insulator elements and bolts ready according to the selection table (see reverse). Join the elements in a insulator band and tighten the nuts just a few turns on the bolts. |
| 2 | Wrap the pipe surfaces in the contact area of the pipe/spacer with a anti slipping protection band to ensure optimum safety against slipping. |
| 3 | Place pre-assembled elements around the carrier pipe and close the final segments. |
| 5 | The square nuts have to be aligned in a way to fit in the corresponding recesses of the insulator segment |
| 6 | Tighten the bolts with a torque of no more than 3 Nm so that the insulator ring is firmly attached to the pipe. It is not absolutely necessary to tighten the bolts completely. |
