PERFECT SYSTEM SUPPORT OF pipes and tubes WALRAVEN


CHAPTER I
Walraven system provides a way of fastening and fixing pipes, montandu is easy. Quickly, with as few accessories. With this system installed pipes for all types of equipment, fast and easy. The components are supplied pre-assembled so that can be installed as soon as they are brought on site. The choice of this system of fixing and attaching tubes ensure perfect installation and high reliability. This system can be used successfully in hotels, halls production, supermarkets and residential buildings. The materials used are subject to laboratory tests periosic ISO 9001, thus ensuring good quality control. The components are made of galvanized steel corrosion treatments subject to a number of steel or sanitary requirements.

SCHOOL
Clamps with rubber gasket can be used for steel and copper pipes, metal and plastic pipe. Rubber seal is designed to reduce transfer of vibrations from equipment to building structure. These clamps with rubber gasket is in accordance with German standard DIN 4109 indicating the general requirements in terms of sound insulation. Noise is caused by vibrations that occur in an installation .Noise intensity depends on the number of vibrations per second and can be measured in Hert but the measured value is expressed in dB. Plumbing pipe systems, for heating or air-conditioning ducts can be good conductive acoustic vibrations, vibrations that occur due to heat flow through the pipes and the pipes connecting module. Other sources that can produce vibrations in the equipment are pumps, valves, fans, valves. Noise may increase if the if the systems that produce vibrations are mounted directly to wall or ceiling, walls and ceiling because it acts as a noise amplificatory. To reduce transmission of vibrations to the building structure should be placed a layer of absorbing vibrations from the pipeline walls. A very good material is absorbent rubber gasket profile that is specifically designed for taking vibration.

CHOICE collars
For a correct choice of necklaces are taken into account :
Loading in the fixing points
Environment that is located
The purpose facility
Material it is made
Medium were assembled fixing points
Distance between fixing points

PURPOSE OF SYSTEM
Cold water installations
Heaters
Rainwater Installations
Chimney
Air conditioning
Drainage systems
Fire fighting equipment

The environment in which plant is locatedInterior equipment: dry and mild. Support equipment pregalvanizare not require treatment.Support equipment pregalvanizare not require treatment.  Industrial plants located in industrial environment: use of galvanized steel clamps that have a minimum of a certain layer thickness. You can use stainless steel. Outdoor facilities located in chemical environment.: Very aggressive environment can affect plant indoor and outdoor installation. Use clamps painted galvanized sheet but prefer stainless steel necklaces. Plants in the food industry: using steel clamps grip the AS 316 can be sterilized.

The material of the plant made
Cast iron pipe
Copper Pipes: pipe clamp, pipe insulation
Steel pipe: pipe threaded pipe flame, simple steel pipe, galvanized drain.
Plastic Pipe: PVC, PP, PE, HDPE, PE-X

Distance between fixing points
Spacing is determined by the elasticity of the pipe clamps.
Installation conditions :
PVC pipe clamps for fixing the distance between the horizontal is 10 times the diameter of the pipe but not more than 1250mm.
It takes into account the distance between a deviation (curve elbow, branch) and the nearest point of attachment must not be less than 5 times the pipe diameter.
This method is used only for large diameter pipes.
Loading in the fixing points
Medium were assembled fixing points.

Supports for attachment points
The pipes are mounted are mounted on all types of media: concrete, brick, metallic skeleton - profile.
It is important that the fixing material (rail fasteners and accessories) clamps and mounting mode (with screws, anchors) to perform together a system.
Choice of fixation depends on the particular necklace.. Maximum mounting rails tasks must be taken of their support rails were installed.
