  1. Knowing Helisystem System
    1. Raw material – polypropylene -random

Polypropylene is a versatile polymer that surrounds us every day . The polymer is formed by carbon-carbon and carbon-hydrogen single connections. Is obtained by polymerizing propylene in the presence of catalysts with certain conditions of pressure and temperature.

According to the classification of polypropylene , we can designate a raw material used to belong to the group of type Random copolymers .
To be obtained polypropylene copolymer are added small amounts of ethylene thus conferring skills production pipeline .

Random Copolymer Polypropylene is characterized by its high molecular weight and resistance to high operating temperatures and pressure conditions , ensuring high strength and length of life.

In this table we find the best-known chemicals. For more information contact the company Heliroma – Plastics , Lda .

Low Thermal Conductivity
Resude substantially traditional thermal condensation formation characteristic of the metal tubes .

Loss of Reduced Charge
Pipes and fittings are characterized by low roughness of the inner surfaces , preventing the formation of scale deposits , minimizing losses.

Soundproofing
The characteristics of raw materials and thicknesses used give the system a high sound insulation.

Organoleptic properties
The PPR is a completely non-toxic conduction system ensuring drinking water .

Adequate lifedecuada vida útil
According to the regression curves can be observed in the graphic below that for plumbing installations temperature conditions defined pressures the system will last 50 years.


Reduced installation time
LThe most important feature of PPR system is the union of all elements by heat . Method insurance is relatively easily ejecutabe traditional products .

SCOPE

The Helisystem system due to its characteristics and referred to above , has a wide range of pressure and temperature applications appropriate destination for the class for application:

  • Distribution of hot and cold sanitary water
  • Central heat;
  • Facilities tubes colunas amounts of large public buildings , hotels, hospitals , schools , barracks , etc.

MANIPULACIÓN E INSTALACIÓN

For a good result in system installation Helisystem should consider some recommendations Heliroma Plastics , Lda . Considers important , as the respective welding technique and linear expansion.

Some recommendations for proper use of the system

UV resistanc
The PPR , like all thermoplastics should not be exposed to direct sunlight

 

Curvature of the tubes
Do not use flame to curves or detours may be affected because the molecular structure of polypropylene.

 

Low temperature resistance
At low ( near 0 ) temperature the system becomes more fragile. Avoid collisions especially at the ends of the tubes, excessive loads and accented folds. Avoid using tube submit incisions or scratches caused during handling.

 

Gaskets in metal connections
Use Teflon or hemp to prevent leakage. Not use accessories or uncalibrated conical thread .

 

 

Court
For a free cutting burrs and perpendicular tube should use cutting equipment in order .

Descripción de Técnica de Soldadura con Polifusora Manual

The joining of pipes and fittings shall be made through a welding polyfusion to 260 ° , with proper equipment supplied by Heliroma . Simply join ( 220v ) and wait .
The flashing of the green indicator lamp will indicate that the soldering temperature is reached . At this time you can start working.

 

After the heating time , -piece without interruption. For a short period of time ( 3s) you can reset the castings (rotations never above 30 °) .
Some time after this merger will have reached its maximum resistance ( see table).

 

Hot simultaneously throughout the depth of the tube and the end of the fitting with socket welding , pressing lightly .

Note : heating times run from the time the pipe and fitting are correctly positioned on the socket welding matrices .

Thermal Expansion
System expansion thermal expansion is defined relative to their size , caused by the vibrations of working temperature and installation temperature .

Therefore be taken into account how the pipe shall be installed : recessed walls or floors or installed on exterior walls or floors ( in sight) .

The first situation is not the most worrisome because the materials themselves covering the expansion system ” absorb ” these alterations.

In the second situation , have to be considered thermal expansion or be compensated for all dimensions contractions and expansions of the material, thus avoiding damage after installation .

Calculation of Linear Thermal Expansion

The – initial tube length , a temperature T0 (m )

L – length of the tube end , at temperature T (m )
.DELTA.L – Linear expansion (L -L0 ) (mm )
DT – Temperature drift tube , em ºC (T -T0 )
α – coefficient of linear expansion , in mm / m ° C ; PPR Pipe for the coefficient of linear expansion ( listed value ) eg :

α = 0.15 mm / m ° C

To achieve solve cases that they occur situations of thermal expansion ( outdoor facilities ) , must necessarily be calculated length variation in free sections , considering the criación lire or changes of direction able to ” absorb” these expansions.

Fixed and mobile points

The fixed points ( PF ) prevent movement of the tube, and this factor must be a strong connection between the pipe and the outer walls . The material used for the connection should be a rigid clamp. Movable points ( PM ) or facilitate sliding movement axially. They should be placed either horizontally or verticalment.

Compensation of Thermal Expansion Plugs for Brazos

Arm length (Ls) is calculated based on the length ( L ) , through the following formula:

Ls – Arm length expansion (mm )
D – Outside diameter of pipe ( mm )
.DELTA.L – Change in length ( mm )
C – Constant PP -R material (20 )

 

Compensation of Thermal Expansion Plugs for Curves

LasThe expansion lira equals two arms expansion , and is used whenever dilation is not absorbed by an arm of change of address.

Expansion arm may be calculated by the following formula:

Lc = 2 x ∆L + ms

Lc – Minimum width of the curve ( mm )

DELTA.L – Linear expansion (mm )

ms – Minimum security = 150 mm

Example:
Bar dimension PPR = 4 meters

Tube diameter = 25 mm
DT = 40

Calculation of Thermal Expansion

∆L = 4 x 0.15 x 40 = 24 mm

C

Calculating expansion arm length for the above example

Calculating expansion curve Lc = 2 x 24 + 150 = 198 mm

Description of tests carried to the tubes and accessories

Flow Index (MFI) – This test consists in determining the amount of mass that passes through a hole ( Fieira ) properly calibrated , to temperature of 230 in a certain period and subjected to a load of 2.160kg . The result will be a difference of less than 30 % relative to the index Fluency raw material.

Longitudinal Deformation Hot – The principle of this test consists in obtaining a piece of tube with a given compliance, which is placed inside an oven maintained at a specific temperature for specified period of time . A compliance marked on this piece of pipe and measured on the same conditions , before and after being heated in the oven. The deformation is calculated on compliance percentage change relative to baseline compliance .
