1.1.0.1 LOGSTOR FlexPipe handbook General - system description System description
This LOGSTOR handbook is primarily directed at the community heating/low temperature (up to 95°C) market with the products: • PexFlex and AluFlex for heating • PEX DW for domestic water Community heating as a concept does not differ essentially from district heating as regards the technical solutions, but primarily as regards the facts that: • the system is connected to a local energy source either by utilising: - existing systems or - new community heating systems • the ownership is rooted locally • the system, by its nature, has a limited size • the pipe dimensions are small, making flexible pipe systems an obvious choice • the temperatures are low, enabling optimisation of the product choice and thus reducing the construction costs. LOGSTOR FlexPipe systems contribute to this with: • good insulating properties. Certified thermal conductivity, lambda = 0.022 W/mK • few buried joints • no welding or soldering. Only mechanical joints. • narrow trenches = minimise the excavation and restoration costs also due to: -- the possibility to use TwinPipe -- the small bending radii -- self-compensating systems. No expansion components

1.4.1.1 Design with FlexPipes General Introduction
This section describes general and product specific rules for designing and dimensioning with PexFlex, AluFlex, and PEX DW.
Design and piping
The design of the pipeline is very simple, because the pipes are self-compensating. That means that expansion movements in the soil shall not be taken into account. in the design phase the following shall be decided upon: -- The design of the trench, see page 3.2.0.1 -- Bending radius of the relevant dimensions, see page 3.2.0.3 -- Introduction in buildings, see section2.6.1. (If FlexPipes are to be connected to existing systems with steel service pipes special rules apply! (see www.logstor.com/Design, section 11.3 and 13.1-2).

The tables in this section are based on the following and are consequently only guiding: -- Flow temperature 80°C -- Return temperature 40°C -- Soil temperature 10°C -- Soil cover 0.6 m -- Distance between pipes (in connection with single pipes) 0.15 m -- Lambda value of the soil 1.6 W/mK If exact calculations with other condistions are required, please refer to LOGSTOR Calculator at www.logstor.com (use the quick link).

1.4.3.1 Design with FlexPipes Pressure loss charts General
In order to establish the correct pipe dimension it is necessary to know the water flow and the maximum allowable pressure loss. Small pipelines are often dimensioned after the available pressure difference, thereby minimising the dimension and the heat loss as much as possible as well as assuring the consumer the highest possible flow temperature. In addition, it must be ensured that the water speed will not be too high. For flexible pipelines it is recommended that the speed does not exceed 2 m/s in couplings and that the speed in house connections does not exceed 1 m/s to minimise the risk of noise. It is recommended that the system is dimensioned after the available pressure difference. In case it is not known, a value corresponding to 150 Pa/m is often used. As a dimensioning tool LOGSTOR Calculator can be used. It is available on: www.logstor.com/calculator. As an alternative to a hand calculation the graphs in the following can be used. Inter-related values between output (kW) and cooling as well as water flow (kg/h) appear from the graphs. The required output is found with the inter-related cooling, or the water flow can be found after the formula: q ≅ Q ∙ 860 ∆T q = Mass flow [ kg/h] Q = Output [kW] DT = Cooling The following graphs are based on: Water temperature of 80°C for heat pipes and 60° for domestic water pipes. Absolute PEX roughness = 0.01 mm

2.2.0.5 FlexPipes PexFlex - transition pipes, TwinPipe - single pipe Application
Preinsulated transition pipes are used in connection with straight transition from a single pipe system to a TwinPipe system. As a standard series 2 dimensions for single pipe ends and series 1 dimensons for TwinPipe ends are delivered for PexFlex. As the flow pipe is always placed at the bottom, the transition is available in a “type 1” as well as a “type 2” version.
Description
"Type 1" and "type 2" are defined by viewing the transition pipe from the single pipe end perspective. Type 1
Type 2 C/C = 245 mm

2.2.0.6 FlexPipes PexFlex - press couplings Coupling types
For PexFlex-systems the three most commonly used coupling types are: -- Straight press coupling: Same dimension -- Reducing press coupling: 1-3 dimensional offsets dependent on the dimension -- Straight branch with press coupling Press couplings ensure a permanent sealing at all temperature variations. Alternative: Straight couplngs as well as T-couplings are also available as compression couplings, see page 2.2.0.8.

2.6.1.1 Terminations with FlexPipes General Possible terminations. Description
In principle there are 4 methods to introduce FlexPipes through a wall: - Straight lead-in through the base - Tilted bore in the base - 90° lead-in through the base with embedded inlet pipe - External lead-in through the wall, covered by a cabinet For internal use a number of possible mountings and valves, adjusted to the pipe type and expansion stress (see under the different FlexPipe types) are offered. Consequently, it is possible to find a solution which fits the specific task precisely.
Straight lead-in throug the base. Wall entry sleeve
Is used by direct introduction into e.g. service space, cellar etc. Component No. 5800. Dependent on whether bore or core has been used a wall entry sleeve may be required.

Storage
• Stock pipes in such a way that they are not damaged. Stack the pipes on a level surface of stoneless sand with cushions of sand as it appears from the illustration. Stack the FlexPipe coils so the maximum height is 2 m.
max. 2 m
Delivery
• Store pallets with foam liquids indoors at 16-22°. • Likewise store shrink materials indoors or under cover. • All casing joints of plastic materials must be stored vertically, resting on one end in order to avoid ovalization.
Unloading
Do not throw or roll pipes and other components directly on to the ground. They must be lifted into place and NOT dragged - neither on the truck bed nor on the ground.
Handling, FlexPipes
Only use lifting straps with a width of min. 100 mm.

3.2.0.1 FlexPipes Installation, general Installation methods
FlexPipes are installed in trenches either horizontally or vertically in accordance with the minimum trench dimensions in the illustration below.
Trench installation
This sectional view of the trench shows the minimum dimensions for: - The sand layer The pipes must be surrounded by min. 50 mm sand or other stonefree backfill material. - The distance between outer casing pipes, 50 mm - The cover H1 = In areas with heavy traffic min. 400 mm from the top of the pipe to the bottom of the asphalt or concrete layer H2 = In areas with no or only light traffic min. 300 mm ! = Warning tape or net The cross section of the trench must allow sufficient space for proper installation of pipes and casing joints and compacting of backfilling. Note! The minimum cover also applies to branching, if any, from the illustrated cross section.
Shortening
FlexPipes are delivered in coils. The required length is cut perpendicularly, using a suitable saw. The casing of the FlexPipe has a metre indication, facilitating the cutting of exact lengths. Example of marking: LOGSTOR PEXFLEX :: VARME - HEAT - HEIZUNG :: EN 15632 :: 20x20/77 MM :: MAX 95°C :: 6 BAR :: PELD :: MADE IN DK :: 198 m

3.2.0.2 FlexPipes Installation, general Unwinding
Do not cut all fixation strings at the same time. Place the coil at the start of the trench. Cut the first string. Unwind the pipe till the next string and then cut that etc.
Straightening
Adapt the FlexPipe end, so that min. 500 mm of it is straight and plane-parallel with the welded branch pipe piece or the adjoining pipe end. This adaptation is important and necessary to ensure that subsequent installation of the casing joint can be carried out according to instructions.
1 2 3
500 L
Please keep the bounce effect of the free pipe ends in mind when cutting.
Auxiliary tools
In case of major tasks and very large dimensions it is advantageous to use a waggon with motorized straightener (not obligatory). The LOGSTOR Service Department can refer to relevant suppliers of the FlexPipe-waggon. NOTE! 1. At temperatures below +5°C the outer casing must be preheated to lukewarm, immediately before it is inserted in the straightener head (soft gas flame during the entire straightening process). 2. It is recommended to store the coil in a heated room at least 24 hours before use - this does not however exclude item 1, if the coil becomes cold again.

3.2.0.3 FlexPipes Installation, general Bending radius

R min.
Bending radius R min. m 0.6 0.8 1.1 1.2 1.4 1.6 1.8
The rigidity of PexFlex pipes depends on the temperature of the pipe. On installation it may be necessary to ensure the pipe position e.g. by partial backfilling. Prior to bending/installation in the pipe trench it is advantageous to preheat the casing pipe in order to reduce the stresses.
Bending Winter measures
Unrolling and straightening do not normally require preheating, only common caution. Preheating is however recommended, if the material (FlexPipe) has a temperature below 5°C, see page 3.2.0.2 “Auxiliary tools”. Ordinarily bending of the outer casing at temperatures below 5°C, requires preheating of the section which is influenced by the bending to lukewarm, The preheating rule also applies to tilted bores in the base or inlet pipes. Bend the pipe slowly and smoothly, not jerkily. Avoid to bend the utmost 25-30 cm of the pipe because of the bounce effect.

Push the compression ring on to one of the pipe ends. Place the compression ring minimum 2 x compression ring length from the pipe end.
Expand the pipe ends with the expander pliers as described in the user instructions of the tool supplier. Note! The pipe end is typically expanded twice in a row, rotating the expander pliers 30°.
Immediately after using the expander pliers the coupling nipple is inserted as far as possible into the pipe. Check that all the ribs of the coupling nipple as a minimum are covered by the pipe. If this is not the case, repeat the expansion process. Before compressing the coupling check again that none of the ribs of the coupling nipple pipe end are visible.

3.9.0.1 Insulating joints General and foam packs Application
There are two ways of insulating joints on FlexPipes: -- F XJoints and T-joints straight F for single pipes are insulated with insulation shells, see the relevant installation instructions. -- SXJoints and T-joints straight for TwinPipes are insulated with foam packs as described in this section.
Foam packs
It is an easy-to-apply method according to which a two-component foam liquid, after mixing and filling, forms an effective insulation with the same properties as in the rest of the pipe system. Foam packs which are stored in accordance with stated rules have a time limit for use of 12 months counting from the stated production week. Foam packs comply with the requirements to materials in EN 253. Foam packs are supplied in insulation boxes with information about contents and storage.

3.10.0.1 Insulating joints Storing and handling foam packs Overview
Besides the correct dosing of foam liquids which is ensured through the filling in the factory and through the numbering of foam pack sizes on joints and cartons, there are 4 factors which are important for a correct foaming process: · Liquid temperature · Job-site temperature · Dry joints · Mixing
Liquid temperature/Storage
It is very important to keep the temperature of the foam liquids within certain limits to obtain a homogeneous foam quality.
1
As the reaction time of the foam liquids depends on the storage temperature (1), the mixing (2) and filling times (3) vary.
2
When the carton is removed from the insulation box a correct temperature of application can be kept for approx. two hours. Symbol key to the shown figures: tree = job-site temperature house = storage temperature The shown figures are found on every insulation box and carton.

3.10.0.2 Insulating joints Storing and handling foam packs Job-site temperature
If the job-site temperature is down to +10° C, then insulation is carried out as described on the carton, the label of the fitting or in this handbook. If the temperature is below +10° C, then the fitting/joint parts - particularly the lower halves - must be preheated with a soft gas flame to 30-40° C. If hot water is circulating in the pipeline, it suffices that the fitting parts have reached a temperature of approx. +20° C.
Dry joints
Moisture in a joint gives a poor foam quality. Therefore, always see to it that - the joint area is dry, before the joint is installed - avoid foaming during rainy weather. If necessary use a tent. - foam the joint the same day it has been installed.
Mixing
Careful mixing ensures a homogeneous foam quality and therefore a correctly filled joint.

3.11.0.1 Insulating joints Using foam packs for shrink joints Application
In FlexPipe systems foam packs are used to insulate joints on Twin FlexPipes.
Tools
The required tools appear from the relevant installation instructions.
Venting holes/ plugs
It is important that the filling holes always face upwards (12 o'clock position).
12
The foam liquid should always be filled into the lower filling hole of the joint to ensure an optimum venting.
The holes in the venting plug ensure that the air in the joint can escape quickly and easily during the foaming process.

3.11.0.2 Insulating joints Using foam packs for shrink joints Opening carton
The cartons with foam packs must be stored in the insulating box until use. Remember to replace the cover of the box to maintain the correct liquid temperature. 2. Open the carton by pulling the perforated flap in the direction of the arrow. 3. O pen up the carton by pulling in the two holes.
Mixing foam liquids
4. P ull at both sides of the bag and remove the clip barrier, so the two liquids mix.
5. M ix the liquids by shaking the bag vigorously and stirring the two liquids with the built-in mixing stick at the same time. Mix the foam liquids carefully for the number of seconds, appearing from the table on the carton, until the liquid mixture is homogeneous light brown. Hold the mixing stick, not the nozzle.
Filling in foam liquid
6. N ow place the nozzle in the open filling hole - the lower hole of the joint. 7. Press the mixing stick into the nozzle, which is supported by one hand.
2 1
8. T wist the mixing stick back and forth several times, until the plastic membrane breaks. It is important that the penetration is thorough, so that the liquids can run down into the joint.

3.11.0.3 Insulating joints Using foam packs for shrink joints Filling in foam liquid, continued
9. S queeze the foam liquid into the joint and flatten/wring the bag during filling, so that no air pockets appear behind the liquid in the bag.
Venting and hardening
10. F it the venting plugs into the filling holes after filling is complete. Proceed with the next joint. The foam liquid expands in the joint, forcing air through the venting plug. When the ventilation is complete, a little foam will be forced through the venting holes. The insulation of the joint is complete, when the foam, appearing at the holes is hard.
Removing venting plug
11. Wait min. 30 min. for degassing to complete. Remove the venting plugs by turning and lifting them. Remove excess foam or spillage, if any.
