NACE SP0170 has long been the industry benchmark for preventing this specific type of degradation. The 2021 revision, however, brings the standard into the modern era. While previous versions (such as the 2014 revision) laid the groundwork, the 2021 document addresses the evolving complexity of modern refining.

: A positive pressure of nitrogen must be strictly maintained throughout the entire shutdown period until the equipment is closed back up and purged of air for startup.

Corrosion is a significant threat to pipeline integrity, causing damage, leaks, and even catastrophic failures. According to the NACE, corrosion costs the oil and gas industry billions of dollars annually. The NACE SP0170 standard helps to minimize these costs by providing guidelines for effective corrosion prevention and control. The 2021 version of the standard incorporates the latest research, technologies, and best practices, ensuring that pipeline operators can maintain the highest level of safety and reliability.

The 2018 standard (NACE SP0170-2018), a concise 16-page document, is a comprehensive guide structured to provide actionable protection strategies:

Using the most recent PDF (e.g., SP0170-2018/2021) ensures the latest technical requirements are met.

“Before standards like SP0170 existed, we saw unexplained cracking in units that had just come offline for maintenance,” says a senior metallurgical consultant. “It was counterintuitive. The equipment was fine while running, but broke while sitting still.”

UserTimeDLL

Download Windows Time DLL

Place the DLL in your DAQFactory installation folder and all DAQFactory will use the Windows system clock instead of the high precision timer.
Works with all versions of DAQFactory, release 5+.

Reasons to use this DLL:

DAQFactory's time is drifting a lot compared to the Windows system time.
You need to synchonize time between machines using a network time server that is automatically syncing the WIndows system clock.
You want DAQFactory to adjust for daylight savings time (see warning below).

Reasons NOT to use this DLL:

You need high precision time stamps and precise looping. The standard Windows clock has a precision of about 15ms. The normal DAQFactory clock has a precision of about 100ns, though time is only recorded to the microsecond.
Daylight savings time is going to mess up your control loops. See below:


DAYLIGHT SAVINGS TIME WARNING:

If you use this DLL and have daylight savings time enabled on your system, when the system clock is adjusted for daylight savings time your control and acquisition loops will be affected:

In the spring, when clocks shift forward, DAQFactory will think it was hung for an hour. This will cause a Timing Lag error on all acqusition loops. Serial and Ethernet communications may throw a timeout error even though comms are fine. Any script that is looking for timeouts, or watchdog scripts may trigger since it will appear as if nothing happened for an hour.

In the fall, when the clocks shift backwards, any loops that happen to be waiting (for example in a delay(), or even simple Channel Timing) will likely hang for one hour while the clock comes back to future time. This means an hour of dead time. Worse, if a loop happens to not be in the delay() at the time of the time shift, it will run normally, so which loops hang for an hour and which run properly is completely random.


We strongly recommend turning off daylight savings time if you wish to use this DLL and the Windows system clock.


If you do elect to leave DST on while using this driver, you should consider using the system.IsDST() to determine when the switch occurs and reset all your loops. Use channel.Restart() to reset an Channel Timing loops.

Download DAQFactory final

To start your download, please click on the following link:


DAQFactory 20.1
Please note that any documents saved in 20.1 will not open in prior releases of DAQFactory.

NOTE: For those upgrading from prior releases (19.x and earlier), the upgrade to 20+ is a significant upgrade. First and foremost, DAQFactory Express is no longer available and not supported in this release. DAQFactory Starter is likewise being deprecated. Existing Starter licenses will still function, but new licenses are no longer available.


DAQFactory trials are limited to 25 days. The trials are fully functioning with only two exceptions: only the first image of each category in the library is available, and your documents will not work in the runtime version. The trial is DAQFactory-Pro which enables you to try all the features. If you have purchased a DAQFactory license, we will provide you with an unlock key to convert the trial into a fully licensed copy with the appropriate features enabled.


If you are upgrading to a new release of DAQFactory you should simply install this download over top of the existing installation. There is no need to uninstall first.


This contains all the DAQFactory files and device drivers available in a single download.
