What to know about Drip Pots and Corrosion Monitoring

Internal metal corrosion in hazardous liquid, gas transmission and gas-gathering applications is inevitable and continues to cause leaks and catastrophic failures.  Due to the fact that internal corrosion is time dependent, the number of incidents could be increasing due to aging pipeline infrastructure.  Such disasters can damage the environment and cause costly downtime and waste in pipeline productivity, in addition to astronomical cleanup costs.

BT6-B Balanced Pressure Thermostatic Trap for Clean Steam

Is your clean steam process getting to the temperature you require?  If not, you may be experiencing condensate back-up or air binding.

If this is the case, it would be prudent to ensure that the steam trap is suitable for the application.  Though clean steam thermodynamic steam traps are suitable for drip applications, a balanced pressure thermostatic trap, constructed of 316L, should be used for process applications.  The balanced pressure thermodynamic steam trap should contain a minimum sub cooled element, be installed to allow for full drainage, contain an un-insulated drip leg of no less than 12″* and be fully open when cold.  In the unlikely event that these can’t be met, traps can be provided with a fixed bleed.

*Please note that the length of the drip leg may be able to be adjusted depending on the load.  The length of the drip leg in light load applications may be shortened, provided that appropriate calculations are made.

Hawk Centurion Guided Radar (CGR) has success with Oil/Water Interface

Application problem

HAWK was recently invited to “put up and show” how our guided wave radar (GCR) could work in a real world environment for Oil & Water interface.  An Oil & Gas Services company located in USA needed accurate measurement of oil level and accurate measurement of the salt water interface in a series of tanks to efficiently separate salt water from oil.

This customer has experienced quality problems and accuracy problems with other manufacturers of Guided Radar devices and they asked us to help.  The problems experienced included inaccurate level readings, high level alarms, signal dropping out, slow response times and constant lack of support.

In addition, this customer was looking for MODBUS communication since this is how they setup their control scheme for the entire Horizontal Pumping Systems (HPS).

Solution

The challenge was for HAWK to prove our Centurion Guided Radar (GSR) system for level and interface measurement.  In addition, HAWK had to develop a MODBUS version of the CGR since the only option was 2-Wire HART 7 version.

HAWK was able to install a CGR 2-Wire Hart device within 2 weeks to prove the ease of set-up and commissioning and a finished CGR MODBUS version within 6 weeks of the request.  Oil level and Salt Water Level accuracy compared with hand dips done over a 3 day period with very good results and the customer’s reaction was “WOW”.

These units have been installed with no special setup or adjustments needed…just the standard HAWK settings.  The CGR installation had the same mounting as the competitors and the same conditions.

This customer has now ordered more than 40 CGR’s and HAWK has become the standard level/interface device!
