The fluids such as liquid, gas and steam, which pass through pipe circuits, bring together some dirts altough these dirts are
very few. These dirts are rust, chalk and so on occurred in old pipe circuits as a result of mud and abrasion. Also, ashes and
gasket parts are other probable dirts. The valves mounted such a circuit cause damage and injury in pumps, sensitive
measurement and calibration instruments. In order to eliminate such damages, it is necessary to place one strainer on the
inlet of all kinds of fittings installed in pipe circuits.
The STRAINER should be mounted as per its conditions and it should also be operated as per its conditions so as to fulfill its
operating principles.
2. APPLICATION
POINTS TO BE CONSIDERED WHEN CHOOSING A STRAINER
The environment where the strainer will be used (The fluid passing through it)
- The environment should be chosen according to of which dark fluid surpluses the fluid is and which
includes liquid, gas, air or solid particles and whether this fluid is corrosive.
Fluid concentration and temperature (Max and Min)
- The operational temperature, max temperature and min. temperature passing through the valve should
be known.
The type of connection to the circuit
- Threaded, flanged, socked, welded or bushed
Conformity to international standards
- DIN, ANSI, CLASS
POINTS TO BE CONSIDERED WHEN MOUNTING A STAINER:
Please consider the following for the valve connection elements on the installation:
- They should comply with the appropriate standard, pressure class and diameter
- Both the axises of the pipes where they will be mounted and the hole axises of the connection element to
be used hould be in the same axis.
- Example: If flange is used as connection element, the bolt hole axises should be in the same axis. (The
excessive tensions occurred on the strainer due to this kind of axis abnormalities will risk the leakage.)
- In flanged connections, bolts suitable for flange holes should be used.
- If the connection element is flange, its bolts will be released by tightening them mutually, then the bolts
will be tightened back in torque values given mutually.
- If the space for strainer is left during installation, both the length of the strainer and the length of the
leakage elements to be used should be calculated before leaving such space.
- If the type of the connection will be threaded, the length of the thread on the pipe should not be less
than the length of the strainer thread.
Please consider the following regarding the leakage element when mounting the strainer on the installation:
- A leakage element suitable for the fluid type and pressure should be chosen.
- The surfaces of the leakage element to be used in flange connections should be smooth.
- Dismantled and distorted leakage element should not be used and should be replaced.
- It should also be noted that, the passage neck of the strainer should not be closed while mounting the
leakage element. (The leakage elements are Klingerit, Teflon, 0-ring and caoutchouc and rubber in
appropriate hardness)
Please consider the following for mounting the strainer on the installation:
- Before mounting the valve, the pipe line should be cleaned with pressure air or steam in order to liminate
the potential burrs, corrosions, foreign substances and dirts which may exist within the line.
- For the strainer to be newly mounted, the labels / covers on both flanges should be removed.
