This tool allows us to find the components and torque for the perfect flange.
Choosing the right components and the best tightening torque is essential for long-lasting, leak-proof flange connections. However, doubts often arise when choosing. This calculator helps you determine components and torque.

How does it work?

• To do this, select the material and dimensions of the pipe, as well as the possible parameters of the installation point: with or without valve, type of flange and gasket.
• As a result, you are given the recommended size and number of bolts, as well as the best tightening torque.
• In addition, you will see the code of all the components of the corresponding products of GF Piping Systems

The link symbol behind the codes will take you to the online catalogue, with detailed technical information and data sheets. Depending on your needs, you can change the selected parameters to calculate various settings. To start the calculation from the beginning and clear all previous values, press the “Reset” button.

This tool allows us to find the appropriate tube or pipe system.
Material, operating temperature and pressure are decisive in selecting the right tube system. This calculation tool helps you to correctly combine the parameters and find the optimal system.

How does it work?

• First of all, select the application: water, gas or industry or other medium.
• Next, enter your temperature and pressure units (°C and bar or °F and psi) and the desired material. You can set or remove the dependency between pressure and temperature value.
• Then enter the media temperature, working pressure and desired pot life.
• As a result, the design factor of the material is displayed in the parameters and on the graph you will see an overview of the temperature and pressure up to which the selected material can be used, as well as your own input for comparison.

If you have selected several materials, you can also display the pressure/temperature curve separately by clicking on the corresponding material below the graph. You can then print the results or email them.

This tool allows us to find the optimal dimension of the valve to use.
Many installers still automatically choose valves and pipes of the same dimensions, although a smaller valve is often better for accurate flow. This calculator helps you figure out the best valve size for your installation.

How does it work?

• Select the valve type and pipe size and enter your process parameters.
• You will then be able to choose between different valve sizes.
• If the operating range of the selected valve is optimal, you will see it in the green zone of the diagram, delimited by two red lines. If not, correct it as follows:
• If the opening angle is in the front orange (“chatter”), select a smaller valve size.
• If the opening angle is in the back orange (“cavitation”), select a larger valve size.
• If there are no red lines on the graph, check if the flow rate is within the range of the selected valve.
• If you do not know the exact value of the inlet pressure (P1) and the outlet pressure (P2), we suggest you start with ΔP = 1 bar / 14.5 psi (ΔP = P1-P2).

This tool allows us to find the dimensions for pressure regulating valves (PVR). Selection of the correct valve size is important to ensure the optimal design of the piping system. This tool helps you select the correct size pressure control valve for your application.

How does it work?

• First, select the valve type, pipe diameter, pressure range, and desired unit (metric or imperial) from the valve data
• Next, enter the desired pressure (P1 or P2) and the flow rate Q as control variables
• The calculation tool will then display the hysteresis curve for the valve at the selected dimension. The point on the curve that represents the work point created taking into account specified parameters.

Use the slider under the curve to adjust the valve dimension and you will immediately find the result of the curve display.

• If the service point is in the yellow range, you would have to set a smaller dimension for your valve on the slider under the curve.
• If the graph does not show a service point, check that the selected flow rate is within the maximum flow rate of the selected valve and that the pressure matches the pressure range selection.

The COOLING calculation tool allows you to calculate all piping system parameters that are essential for cooling, such as pressure loss, heat loss, shrinkage and temperature loss. The COOLING calculation tool helps to carry out all the necessary technical calculations.
This is a downloadable tool.

How does it work?

• First, enter your preferred pressure unit and system of units. Options are Bar or kPa, and ISO or ASTM, respectively.
• Next, define the system parameters, p. eg piping system, fluid, flow temperature, ambient
  temperature, and wind speed.
• Click “Calculate” to get the results.

To perform a new calculation, click on the first “Clear” button. If you wish, you can print the results by clicking «Print».

K-factors are calibration values (pulses per unit volume) used to convert flow sensor output frequencies to flow rates. This calculation tool helps you determine the correct K factor for your flow sensor.

GF Signet publishes K-factors for water only in gallons (powder per gallon) and liters (powder per liter) for all flow sensors, in all applicable pipe sizes and materials, or in all pipe fitting sizes and applicable installation splice materials. Contact GF Piping Systems Japan for JIS K-Factors.

K-factors for liquids other than water must be determined empirically, usually in situ using a secondary parameter. The number of pulses per volumetric unit may vary depending on the medium and the installation. For optimal performance, the system should be calibrated after installation.

How does it work?

• Select the type of splice you use.
• Choose the Signet flow sensor you are using.
• Fill in the parameters to get the K factor.

NOTE: For other pipe sizes, statistical K-Factors may be available in the K-Factor Calculator online tool. Alternatively, contact technical support for more information. The roughness of the pipe can influence the K factor; this is not taken into account in the calculation method. K-factors are calculated for the following selections and are approximate values. For best results, do a flow calibration.

This tool allows us to find the right splice for your sensor.

The quality of a process automation system depends on the sensors and the installation. If you use the proper splice, installation is much easier. This tool makes it easy to find the right fitting that brings the sensor to the system, taking into account the material, parameter and size of the piping system.

We offer a wide variety of different sensors, such as flow, pH, ORP, pressure or temperature sensors and the appropriate installation fittings. This simple sensor/fitting lookup tool helps you find the right pipe fitting for your GF Piping Systems sensor.

The sensor/junction search tool helps you with our standard solutions.

How does it work?

To do this, select:

• Sensor type
• The parameter you work with
• The size
• The material used in the piping system

As a result, you will see on the left side the range of possible sensors and on the right side the compatible installation splices, in both cases grouped by type.

Within each type, there are different versions. Select your favorite version. Clicking on the part number will take you to the product page.

Depending on your needs, you can change the selected parameters to have multiple constellations.

The tool automatically updates the results.

To start the selection from the beginning and clear all previous values, press the “reset” button. If the requested match is not displayed in the selection of the sensor/fitting search tool, please contact your local GF Piping Systems sales department. We have a wide range of options that will surely fit your needs.
