High Pressure Flow Control Female Thread SS Needle Valve
1. SS needle valve is an important part of instrument measurement
pipeline system, which mainly includes globe valve and ball valve.
SS needle valve’s function is to open or cut off the pipeline.
2. The ferrule type instrument valve has the advantages of easy
installation and disassembly, tight connection, good fireproof,
explosion-proof, high pressure resistance and good sealing
performance.
3. SS needle valve is an advanced connection type valve in power
station, oil refining, chemical plant and instrument measuring
pipeline. This kind of valve should be installed horizontally in
the pipeline. The SS needle valve has good sealing performance and
long service life.
4. Even if the sealing surface is damaged, SS needle valve only
needs to replace the vulnerable parts and can continue to
use.During installation, the flow direction of medium shall be
consistent with the arrow direction on the SS needle valve body.
Anti corrosion method
First of all, the anti-corrosion of the SS needle valve body is
mainly the correct selection of materials. Although the data of
anti-corrosion is very rich, SS needle valve is not easy to choose
the right one, because the problem of corrosion is very
complicated. The difficulty in selecting SS needle valve body
materials lies in not only the corrosion problem, but also the
pressure and temperature resistance, economic rationality and easy
purchase.
The second is to adopt lining measures, such as lead lining,
aluminum lining, engineering plastics lining, natural rubber lining
and various synthetic rubber lining.
Thirdly, in the case of low pressure and temperature, using
non-metal as the main material of valve can often effectively
prevent corrosion.
In addition, the external surface of SS needle valve is also
corroded by the atmosphere.
