DESCRIPTION OF NEW GENERATION INSULATION SYSTEM PURPOSED FOR MEDIUM AND LARGE-SIZED TANKS INCLUDING HEAT ACCUMULATORS AND ANY OTHER STORAGE TANKS

Thermal insulation used to manufacture the modules – insulating panels is made from polyurethane, that several decades has been recognized as one of the best and most durable insulating material in o o many respects up to a specific thermal strength of 150 C or up to 160 C for a short time, and with l =0.0226 W/mKW. The modules – insulating panels manufactured during the production process 10 feature with the structure that upon installation corresponds to the cylindrical shape of the tank. The panels are ready for assembly on site and are tailored to the dimensions of the tank.

New Generation Modular Insulation System features with a self-supporting, independent structure of longitudinal and butt locks that generates no heat loss, eliminates thermal bridges and does not require steel load carrying structure and pins fixing the insulation to the tank. Each module – panel is a part adapted to the shape of the tank and upon installation of the first lower ring and connection of the panels, the whole forms the shape of a cylinder – see photo. Insulation after installation of all panels and rings on the cylindrical part of the tank provides vertical spaces between the modules that create a tightly sealed two centimeter air pocket between the outer wall of the tank and the inner side of the insulation. The air pocket forms the first non-dependent and free thermal insulation and the whole provides the effect related to a thermos. Each of the 12 vertical partitions of interconnected panels facilitates a visual inspection of these parts or mounted sensors in respect of potential medium leakage that will be shown on the bottom at the start bar or will be shown on the screen or traffic light mounted on the tank shell of each vertical part in the case of leakage sensors. The tank roof is provided with modules – polyurethane flat panels in the shape of triangles with butt and longitudinal locks.

Upon installation they form a tight and mechanically resistant insulation of the top bottom. The casing shell of the panel insulation is provided with Alu Zinc coated flat steel sheet, aluminum metal sheet painted or coated with plastisol, available in any color, combined with insulation panels in the manufacturing process. Optionally the casing shell may be provided with metal sheet in the form of a vertical trapezoid. Upon checking the tightness and effectiveness of the insulation installed on the tank, the insulation is inspected with a thermal imaging camera and then the trapezoidal shells are mounted to three peripheral steel rings made from 3mm thick metal sheet, which are mounted directly on the insulated panels of the tank what eliminates thermal bridges. Insulation panels of the bottom in each case are secured with a flat sheet metal installed with a gradient, and are finished with a tight air pocket of the vertical bulkheads and the bottom. Thickness of the insulating panels depends on temperature of the protected medium and climate zone.

INSULATION AND HEAT DISTRIBUTION SYSTEM ENGINEERING NEW GENERATION MODULAR INSULATION SYSTEM COST-EFFICIENT AND ECO-FRIENDLY OVERHEAD AND UNDERGROUND HEAT DISTRIBUTION SYSTEM INSULATION

New Generation Modular Insulation System has been designed to reduce optimally heat loss within the heat distribution system and contribute to reduction of greenhouse gas emissions also. Insulation system was designed in response to an increased demand for such solutions due to degradation and aging of thermal insulation of existing overhead and underground district heating systems generating big transmission heat losses.

Modular Insulation System has been certified by research laboratories and institutions that confirmed performance values (lambda), and carries the hygienic approval, construction approval regarding use of system for insulation of heat distribution systems and industrial processing installations

Our offer includes straight insulation panels 1.20m long along with 16cmbutt lock, 2.70mlong along with 16cm butt lock, of thickness within range 60mm to 150mm depending on pipeline diameter. Insulation thick over 150mm is also available upon o request. Air sockets ensure efficient performance within temperature from -60 C to o o + 160 C, and over 350 C in case of insulation provided with specially designed rock wool resistant to high temperature.

The patented innovative Modular Insulation System is provided with longitudinal labyrinth lock (see photo) installed on both sides of panels and two-sided butt locks with wedge-snap-in (pull-up and overhang) 160mm long, which upon installation and during system operation ensure 100% protection against leaks of butt joints ensuring linear expansion of installations and preventing uncontrolled heat loss. Insulation system prevents thermal bridges and does not include connecting metal parts e.g. steel load carrying structure. On the wholeperimeterand length of the pipeline and elbows, 10mm thick air sockets (ensuring an effect related to thermos) are provided, including four or less tight, intra-modular bulkheads, dependingonlength of insulating panel. This solution effectively reduces convection which is important when creating a heat accumulator.

Straight sections, elbows, tees, slip supports, fixed points and all fittings of overhead pipeline are protected by sheathing provided with 0.75mm thick galvanized or zincaluminium red oxide steel sheet, and hard PVC film with airtight bands provided on butt and longitudinal joints in case of underground network.

In case of overhead network, this technology in as much as 98% enables rivetless assembly what prevents sheathing damages of straight sections modular structure, what ensures aesthetic effect. Upon request, straight section sheathing and a multi-segment elbow may be marked with an embossing indicating name of network, its owner and manufacturer. Insulation system provides also insulation for steel or concrete fixed points and slip supports. For overhead and underground networks, it seals the additional insulation layer (insulation on the pipeline) with the steel point or concrete support of the network’s sliding supports. Slide support insulation features with internal dimensions bigger than the support itself, what allows smooth operation of the slide longitudinally at linear extension of the network without any leaks or failure of insulation. The structural elements of sliding support and fixed points insulation are very important for maintaining the tightness of the insulation and form the coherent parts of the entire system of insulation.

Modular Insulation System is the only technology among those available on the European market, which thanks to the patented and applied solutions provide tight insulation and prevents leaks caused by network natural linear expansion and consequently uncontrolled heat loss, especially on the duct network.

The thickness of the insulation panels is selected in relation to the temperature of the protected medium and to the prevailing conditions in the geographical zone.

INSULATION AND HEAT DISTRIBUTION SYSTEM ENGINEERING

Inter Moduł Control System

IMCS developed by our Company is a preventive early system warning against uncontrolled leaks or heat distribution network failure.

The system consists of peripheral sensors mounted e.g. on welds, detector sensors, cables and a central monitoring system. The nodes are located at the top in the pipeline insulation close to sensors.

The detectors are located in the heat chambers, one for each pipe. The control system is located at the Investor’s premises. The nodes are designed to connect the perimeter sensors with a transmission cable connected to the detector. The detector monitors condition of the installation protected by insulation and sends data to the control system. The control system includes a computer that collects and displays data collected from detectors installed by the Investor.

Manual readouts are also possible from the detectors installed in underground chambers in case of pipe heat distribution network, and closed and protected boxes in case of overhead network.
