Classification of connections
1.Demountable: connections can be removed from the system after installation
2. Nedemontabile: connections that can not be removed after being installed
3. Tensile strength: connections that can not be removed from the system by pulling
4. No tensile strength: connections that can be removed from the system by pulling the pipe
BUT WELD
The pipes can be welded with any diameter between 32 ÷ 315mm.
Connection characteristics
a) nedemontabil
b) tensile
Use
Can be used in all installations are performed on site or beforehand in the workshop.
Not recommended welding at installation.

Butt welding is a welding method widespread.
It is a combination safe and can run fast, that does not require introduction of additional material.
Pipes and connections combined with this type of welding are given a set of high density polyethylene characteristics. (HDPE)
A) ELECTRIC SLEEVE
It is available for diameters between 40 ÷ 315mm.
Connection characteristics
a) nedemontabil
b) tensile
Use
Spot welding, processing or execution of additional installations, repair, modifications.
Heating and melting zone is divided into two, because in the middle of no existence of an electrical resistance sleeve.
It thus achieves a very good welding
Pressure required for welding is obtained by contracting the heating sleeve.
Electric sleeve can slide by removing the central locking clamp
To run electric welding sleeve is recommended processing devices.
Preparation for welding of two pipes together with electrical sleeve
1. Take two pipes, each pipe is measured at one of the edges with tape lengthwise to within 3.5 cm.
Is a sign on each pipe, cut debavureaza perimeter signs, and clean the terminals (where you cut) of the finger.
Will dry parts of the combined mandatory and will take care to remain dry throughout the execution of welding together.
Warning!
I. Parties will remain dry cleaned during welding
II. Do not touch them ready area.
2. Place the ends of tubes which are to blend prepared (cut, burrs, cut, dried) in the locking sleeve to collar.
If this necklace lock must be eliminated, limited depth introduction to 3cm
B) JOINT jaw jack
It is irreplaceable for diameters between 32 and 315 mm.
Connection characteristics:
a) removable
b) is tensile
Use
Connection with the joint socket can be used as a connector between the various components providing and laying precast simplified.
Installation
Can be used vertically and horizontally
Connection with the joint socket has an external diameter smaller than the male thread.
For this reason we recommend use of space where there are problems.
Connections with socket joints are provided with protective cap for the site.
For the same diameter, depth of entry is the same whether using plug connectors with threaded joint or joints.
Since joining the connector has no function dilated duct must be introduced to its end..
A perfect blend is obtained at 15 ° tube debavurand and lubricating grease with VALSIR.
Do not use oils that could damage the seals
C) THREAD CONNECTION WITH
Clasificarea racordurilor
a) removable
b) is tensile
Use
The socket connection is used as a connector between several prefabricated components, especially if it is necessary simply removing the pipes.
The procedure for mounting the jaw socket joint.
Threaded coupling components
-Locking-nuts
- ring glands
- gasket
- threaded nipple
D. ) Expansion sleeve
It is available for diameters between 32 ÷ 315mm
Classification of connections
a) removable
b) is tensile
Use
Sleeve expansion is essential for connecting the columns on each floor drain rainwater, or that are mounted inside or outside the building.
Where buried sewers can be used as a simple sleeve.
Installation
It is used in upright or horizontal, due to its depth, the connector facilitates installation and collectors columns, allowing the performance of any corrections.
Particular form of seals allows sliding the connector tube at the stage of expansion and contraction, providing perfect sealing of connection, even in a period with high hydraulic load.
Executing a perfect and easy installation of the sleeve
aclean the end that is inserted at an angle of 15 °.
b) lubricate the parts are introduced.
c) introduction will follow the instructions for use indicated on the connector.
Do not use oils that could damage the seals
E) Connection with thread and collar LOCK
It is available for diameters between 40 ÷ 110mm
Classification of connections
a) removable
b) is tensile
Use
If there is axial traction or the possibility that tube out of threaded connection, you must use the locking collar and providing tensile strength of connection.
We recommend using the connection screw and locking collar and when the tube placed on the floor or screed is longer than 2m.
F) Flange connection
It is available for diameters between 50 ÷ 315mm
Combining features
a) removable
b) tensile
Use
Flange can be used to develop a joint system in industrial removable.
Flanges are made of a special aluminum alloy, painted with epoxy powders steam resistant to salt (ie resistance in industrial areas near the sea or ocean).
Using a blind Flas creating the possibility of access is possible for larger diameter tubes (200 ÷ 315)
Componentele racordului cu flansa
1 Screw.
2 Hollow flange
3. Clamp fixing
4. Flat gasket
5. Latches
6. Nuts and washers
G) Manson joined with CONTRACTS THERMAL
It is available for diameters between 50 ÷ 125mm
Combining features
a) rigid nedemontabila
b) yielding to pressure
Use
Joining sleeve thermal shrinkage allows connection to most of the special materials.
Installation.
Rubber ring should be placed at the end of the tube
Contractor is required to ensure that the rubber seal to be located exactly half length sleeve.
Push sleeve joined with extreme thermal contraction tube.
Preheat connection constantly moving flame at a temperature of 125 º.
Sleeve will contract producing a tight joint.
Fit tube jointing sleeve thermal shrinkage with the anchor ring.
VENTILATION branch Mixed HDPE - VALSIR
Branch special ventilation is a piece that is installed on the discharge columns on each floor.
Its use avoids the installation of ventilation column, due to its geometry and hydraulic properties.
Branch exhaust ventilation plant offers the following features:
- lower exhaust speed
- ventilation at each branch
- different possibilities of connection to the storm
Installation is welded together.
This branch is beneficial for buildings over 10 floors.
Vent branch connection to each floor to allow at least 2 toilets, 2 bathtubs, shower trays.
Ventilation with 110 diameter branch has the following connections:
- 3 connections diameter 110
- 3 connections diameter 75
- For mixed operation takeover ramifications, it is important not to be carried out simultaneously connections.
Ventilation leads are delivered inchise.Imbinarile branches can be made by welding together after dark extremities were cut.
Warning !
After foot column will be a ventilation system
