SIPHONE TUBES TYPE U

SIPHONE TUBES TYPE U

The task of the siphon tube is:
• Protection of the measuring device against pressure pulsations
• Cooling the medium (gas or liquid) before it flows into the pressure gauge
U type siphon tubes are made in three types:
UA – U-shaped with pressure supply and discharge in one plane
UB – U-shaped with pressure supply and discharge in two mutually perpendicular planes
UC – in the shape of a double U letter with pressure supply and discharge in one plane

There are both varieties with threaded connection and for welding. The UC tube according to PN is only available in one variant (as in the figure). The tubes are made of seamless tubes, 13.5 × 2.9 steel grade R35. Permissible operating temperature: 300 ° C, maximum pressure at this temperature is 25MPa.
Option: material made of acid-proof steel.
In the U-shaped tube part condensate protects the measuring instrument from the direct action of the medium being measured. Before the first start-up and after its installation, fill it with water or other suitable medium.
To avoid the necessity of emptying the system, it is recommended to mount a siphon tube with a manometric cock, fig.525 / 528, or a manometric valve (depending on the operating parameters).
SIPHON TUBE P TYPE (LOOP PIPES) are also available.
It is recommended to use siphon pipes with high quality components as below:
1. M100R PRESSURE GAUGES
2. MANOMETRIC CELLS FIG.525
3. MANOMETRIC STEELS FIG.528
4. PN400 2-WAY MANOMETRIC VALVE
5. PN400 3-WAY MANOMETRIC VALVE
PRODUCT ACCORDING TO PN-EN 562
