3 Introduction Standard pre-insulated pipes offered in this catalogue are primarily used for heating or cooling distribution systems including the following applications: low temperature hot water heating, medium temperature hot water heating, high temperature hot water heating, primary hot water service, chilled water, condensate and others. However, other applications with specific materials are available upon request. Wehotherm Standard is used for heat distribution. It meets the requirements of European Association standards (including the German Association AGFW / FW401 and EUROHEAT & POWER), and the harmonised European standards EN 253, EN 448, EN 488, and EN 489 as amended. These pre-insulated pipes are manufactured from steel pipes insulated with hard polyurethane foam covered with a layer of polyethylene. The standard series is intended for a maximum working overpressure of 2,5 MPa and a maximum working temperature of 142 C (150 C on a short-term operating basis) with a service life of 30 years. In addition, we can offer pipes with increased thermal resistance of up to 165 C, also with a 30-year service life. Wehotek Spiro is used for above-ground heat distribution. These pre-insulated pipes are manufactured from steel pipes insulated with hard polyurethane foam, and covered with spiral overlaid steel zinc-coated sheets. The pipes are intended for a maximum working overpressure of 2,5 MPa and a maximum working temperature of 142 C (150 C on a short-term operating basis) with a 30-year service life. In addition, we can offer pipes with increased thermal resistance of up to 165 C, also with a 30-year service life. Wehotherm Twins is used for heat distribution. These pre-insulated pipes are manufactured from steel pipes insulated with hard polyurethane foam covered with a layer of polyethylene. The insulation is applied to the supply and return pipes, forming a pair. The pipes are manufactured in compliance with EN The standard series is intended for a maximum working overpressure of 2,5 MPa, a maximum working temperature of 130 C, and a maximum temperature difference of 50 C between the supply and return pipes, with a 30-year service life. Wehotek PPR is used for hot water distribution designated as HSW - Hot Service Water. These pre-insulated pipes are manufactured from polypropylene PP-R pipes, insulated with hard polyurethane foam covered with a layer of polyethylene. This pipe system is designed for a maximum working overpressure of 1 MPa and a maximum working temperature of 70 C, with a 25-year service life. Pipe systems for other applications In addition to the above standard systems, we manufacture pre-insulated pipes which can be produced in other materials according to customer requirements. Uponor Infra Fintherm has extensive experience with the insulation of pipes for the chemical and refrigeration industries, water supply utilities, sanitation, and others. The long-term operating temperature range using polyurethane insulation is between -196 C and +142 C, and with up to 150 C for short-term operation. For higher operating temperatures of up to 165 C, we offer pipes with special polyurethane foam insulation, capable of handling higher temperatures. For media-carrying pipes, we can manufacture systems in steel, stainless steel, acid resistant material, galvanised steel, copper, polyethylene, polybutene, polypropylene, glass fibre, PEX, cast iron, and other material with polyethylene or metal spiral overlaid sheet depending on the specific application. Wehotherm pipe systems are produced with Nordic system sensor wires as a standard, in compliance with EN Pipes with other types of sensor wires (e.g., Brandes, Hagenuk, and Isotronic) can be supplied upon request. Uponor Infra Fintherm reserves the right to make changes without prior notice. 1 / 2015 For the latest technical information see our websites 3

15 Wehotherm Standard T-branches The following are used to branch off the main pipe: 012a Wehotherm Standard Parallel branch Elevated branch Straight branch Implementation of the steel T-branch from the main route: 1) Necked-Out (Collaring) T-branch Standard T-piece Standard design using the cold-forming method for the neck and the V weld. An advantage of this design is the higher overall strength of the V weld compared to a fillet weld, and better shape for the flow of the medium. 2) Forged T-piece For a branch of the same dimension as that of the main line, welded-on forged T-pieces are to be used in accordance with EN , with the same wall thickness of the main line branch base and the branch. 3) Welded tube fitting In exceptional cases, when it is not technologically possible to use another construction method for the branch, branching with a fillet weld is used. Construction with reinforcement is also possible. 015 In the case of higher strength requirements for the branches, it is possible to supply T-branches with thicker walls; we recommend consulting Uponor Infra Fintherm technical department concerning the wall thickness, or determining such requirement based on static strength calculations according to the specific conditions of the project. 1 / 2015 For the latest technical information see our websites 15

23 Wehotherm Standard One time compensators Expansion D k Wehotherm Standard 024en One time compensators are used to reach the desired values of pipe prestressing and maintaining it at a stable value. Backfilling can be done prior to pre-heating of the pipe; only expansion joints are left unsealed. If the depth of the cover over the pipe changes by more than 25%, the expansion of the pipe is enabled in a section with deeper installation by using plastic foil around the pipe casing. We recommend consulting the technical department of Uponor Infra Fintherm about the installation. DN Expansion PN 25 D k , , , , , , , , , , , , , , ,0 Important note: The compensator s position is stabilized with welds during transport. For pressure testing, the compensator must be secured against expansion with weld joints. When the pipe joint is foamed, the temperature must be in the range of 10 to 40 C. Before the compensator is installed, it is necessary to push the joint on the compensators. The one time compensator is installed in the joint at its full length. Preheating, the contraction of the compensator must reach the calculated thermal expansion of the piping. The joint is blocked in the compressed position by welding the compensator. 025 The compensator is covered by the compensator joint, which must be ordered separately, and the specific joint type must be determined by the customer.

They have to be used at bends, branches, reducers, valves, and end fittings. Material of expansion polyethylene profile pads is cross-linked Polyethylene, which has a long service life because it has increased resistance to the effects of soil moisture and chemicals. The profile pads are cut on-site to the required size according to the outer diameter of the pipes to be sheathed. D 073d Multi layers of expansion pads can be used if it is necessary to handle larger expansion and according to the type of soil, and at the same time it is necessary to sheathe the pipes so as to avoid the accumulation of heat on the pipe casing. In the case of pre-heating, the pre-insulated pipes are covered on both sides.

58 Accessories 6.4 Joints Joints are used for the insulation of a pipeline in the welded areas of the carrier pipes, connecting its individual segments. The joints have dual functionality: they protect the PUR insulation against mechanical damage and prevent moisture from entering. Selecting the right type of joints significantly influences the quality and service life of the pipe system. Provided that the installation procedures are followed carefully, all joints offered are suitable for sandy, clay, dry, and wet soil and meet the requirements of EN 489. All materials required for joint installation, including components for the production of polyurethane foam, which comes in bottles, cans, or in the form of prefabricated parts, are provided as standard. To achieve the highest quality of joints for larger dimensions and the correct mechanical and thermal insulating properties, Uponor Infra Fintherm offer mechanical foaming of these joints directly on-site. Types of joints according to their technical performance and application: JT electrically weldable shrinkable joints are suitable for the most demanding conditions with the least favourable load, or for sites with ground water. JZ cross-linked shrinkable joints are designed for most demanding conditions subjected to adverse stress and can also be used in sites where ground water occurs. DSJ double-sealed shrinkable joints are suitable for most applications and this is the most commonly used joint type. Two independent seal systems prevent moisture from entering the PUR insulation. Accessories WE extrusion longitudinally welded joints for repairs are designed for repairs. For installation of WE extrusion longitudinally welded joints it is necessary to extrusion weld the polyethylene. This type of joint can be used on previously welded carrying pipe. 200a See below for more information on joints. 58 For the latest technical information see our websites 1 / 2015

59 Accessories The selection of a specific joint type depends primarily on: - Joint size - Soil factors (level of ground and surface water, oil and other contamination) - Knowledge and experience of the assembly personnel - Number of thermal cycles - Stress rate the joint is exposed to - Service life of the joint - Requirements of the designer and the project investor Thanks to our many years of experience, our sales representatives or engineers will recommend the best type of joint for the project. The joint installation must be done in accordance with EN standards by trained personnel with valid certification from Uponor Infra Fintherm. The certification confirms the theoretical and practical knowledge of installation of pre-insulated pipe joints. This knowledge and practical testing during the training programme helps minimize risks and possible damage which may be incurred by failure to adhere to the correct procedures and to adapt the installation of the joints to the environment. After the training programme, the installation workers will have gained the following knowledge: - Information about the types of joints used and installation procedures - Joint foaming process using cast PUR foam - Safety regulations applicable to the installation of the joints and PUR foam - Storage conditions for the individual components - Disposal of waste generated during the installation of joints - eak detection systems used for pre-insulated pipes (Nordic, Brandes, Hagenuk, and Isotronic) Information on the procedures of joint installation is provided in the installation manual, which is available at Accessories 1 / 2015 For the latest technical information see our websites 59

72 Accessories 6.13 eakage detection system Wehotherm pipe systems are manufactured with Nordic system detection wires as a standard, in line with EN We can supply pipes with other types of detection wires (e.g., Brandes, Hagenuk, and Isotronic) upon request Detection principle Pre-insulated pipe systems enable the electronic detection of any leakage of the carrier pipe and its casing. Detection wires serve as sensors, and are located in the insulation foam together with the carrier pipe. AII pipes and joints are equipped with at least two wire sensors which connect into seamless sections in order to monitor the whole system. Special sensors are then connected to the individual sections. Conductometry Conductometry, i.e., the measurement of the electric conductivity of fluids, is the basis of operation for all sensor types. eakage of fluid into the piping insulation layer creates a bridge between a detection wire and the pipe (or between two wires). If acceptable leakage is exceeded, a defect is signalled. Reflectometry The highest class in the field of leakage sensors consists of instruments operating on the principle of reflectometry - the measurement of electric signal reflections in a conductor. A defect (wet insulation, broken wire, short-circuit) is a disturbed electric homogeneity which induces a partial or total reflection of the electronic impulse, from which the instrument determines the nature and location of the fault. Thanks to conductometry, it is also possible to measure electric capacity changes caused by fluids gradually proceeding through the foam towards the detection wires (before contact) Sensors Sensors can be divided into stationary and portable types based on the method of their use, and in turn into indicatory and localization types based on their ability to determine the distance of the fault. Stationary sensors - located inside a suitable structure for permanent monitoring Portable sensors - designed for operational measurements in any part of the system Indicator sensors - only warn about a fault in a controlled section ocalization sensors - able to determine fault location as well Selection of the detection system Accessories An appropriate measuring device must be determined for each type of leak detection system for the pre-insulated piping. Please contact the Uponor Infra Fintherm technical department, who will help you select the appropriate type according to your requirements and the sensor wires used. 72 For the latest technical information see our websites 1 / 2015
