A preinsulated pipe is made up of an inner pipe that transports materials, an outer coating pipe and a thermal insulator between the two layers. The MVA-ISOLAR system contains all the components and accessories that are necessary for building a thermally insulated pipeline.
With metal coating:
Complex manufacturing or pre-insulation of pipeline components supplied by the customer.
There is a possibility of manufacturing components not included in the booklet, according to special, unique requirements, following personal contact.
If specially requested, it is possible to use pipes that are different from those given in the tables below showing the products in size, accuracy, material and preparation.
Steel service pipe: St 37 grade welded or seamless, according to DIN 1626/DIN 2458, or MSZ EN 10216-2:2002, MSZ EN 10217-2:2002, MSZ EN 10217-5:2002.
1. spirally folded aluminum sheet-pipe for pipes exposed to solar radiation and indoor open pipelines
2. HDPE pipe for underground, directly earth-covered pipelines
If specially requested, other eg. HDPVC, PP, etc.
Coating pipe: primarily high density polyethylene (HDPE) pipe according to MSZ EN 253:2003 or spirally folded aluminum pipe.
Up to 138+2 °C for long-term operation, (150 °C short-term maximum load) PUR-foam.
For long-term use over 140 °C highly heat-resistant, inorganic insulating material, accompanied by PUR foam.
The outer coating pipes of the preinsulated sectional pipes are fastened with the use of shrinking sleeves and MPL-2 band. Security against water is provided by another protective system in the ISOLAR system, which is manifested through the flexible sealing component used during the production and the on-site fastening of the sectional pipes.
The ISOLAR preinsulated pipe system allows for an installation with respect to local specialties. This advantage results from several different aspects that are characteristic of the system:
The use of the preinsulated pipe system and pipe building system is of great variety.
Based on experiments, investigations and building experience home and abroad, together with the use of the newest research results, the manufacturer is constantly widening the applicability of the ISOLAR system, bringing it closer to the expectations of customer's special requests.
Today electro sleeves are also available that make homogeneous coating possible.
There are also new constructional fixed components that ensure the lack of corrosion and stone-bridges. It is also possible to create a bound and a sliding system with the help of adequate planning and choice of components.
There is a constant adhesive (force-transmitting) connection between the inner pipe and the coating pipe containing the insulation.
There is a sliding, frictional connection between the inner pipe and the coating pipe containing the insulation.
It is possible to order this system as an accessory of the ISOLAR system to control the undamaged condition of the preinsulated pipe-system in use. It also indicates accidental leaks in the inner pipe or the outer coating pipe (that is the soaking of the insulating material) and informs about the possible place of the leak.
If specially requested the MVA-ISOLAR pipe components can also be manufactured with electronic heating wires of different temperatures (from +40 to +120 °C), or with accessory hot water or steam heating pipes.
In this case the temperature of the material to be transported can be maintained over long distances and also during shutdown.
