Rohrback Cosasco launches new NACE compliant, lighter weight 6000 PSI Double Block & Bleed Service Valve.

A new 6000 PSI Double Block & Bleed (DBBV) service valve is the latest advancement in Rohrback Cosasco corrosion monitoring solutions. The double block and bleed service valve is safer than a standard service valve and is often mandated by the oil and gas industry or operator policy for improved safety. The fundamental difference between this new advanced safety DBBV service valve and the standard service valve is that the double block and bleed valve has a secondary ball/sealing surface to retain pressure in the event that the first ball or sealing surface is damaged.

Wall thickness and temperature meter

Rohrback Cosasco launched the ULTRACORR2, the next evolution in the portable ULTRACORR Corrosion/Erosion Monitoring System which provides the highest resolution and most cost effective, direct wall thickness and temperature measurement on a pipe or vessel, using fixed Ultrasonic transducers mounted at various locations throughout a site.

Test corrosion on downhole materials

Production wells typically contain water, carbon dioxide and hydrogen sulphide. This combination of elements along with varying temperatures, creates an extremely corrosive environment, subjecting the downhole tubing to corrosion damage including metal loss, pitting and stress corrosion cracking. The Downhole Coupon Holder Assembly (DCHA) was developed to test the effects of different types of corrosion on downhole tube materials, including general corrosion, crevice corrosion, stress corrosion and pitting in downhole conditions. The DCHA holds up to nine coupon holders, including Bent Beam, Strip and Cylindrical. The three types of coupon holders can be “mixed and matched” according to the type of corrosion effects users are evaluating. The DCHA is normally used conjunction with the DCMS Downhole Tool, but may also be installed separately. If more than nine samples are required, multiple DCHAs may be mated together.

Downhole corrosion management

Rohrback Cosasco launched a newly re-designed DCMS Downhole Corrosion Monitoring System for downhole well corrosion management. The Downhole tool is a tubular electronic instrument that uses a Corrosometer electrical resistance corrosion probe element to determine the rate of metal loss within the downhole tubing. The Downhole corrosion monitoring tool automatically reads and records the corrosion probe at regular user defined intervals. Upon retrieval of the Downhole tool the corrosion rate history is downloaded to a PC using Corrdata II Software.

Soil Corrosion Rate Monitor

The new Soil Corrosion Rate Monitor measures corrosion rate, quickly and easily, in a wide range of soils. The monitor allows pipeline operators to quantitatively determine soil corrosivity for the External Corrosion Direct Assessment pre-assessment process, at the time of the pipe excavation or inspection. Determining the level of soil corrosivity before pipeline construction begins allows proper measures to be taken to minimize future replacement and maintenance costs incurred by corrosion damage. The Soil Corrosion Rate Monitor consists of a portable Corrater Aquamate LPR instrument and the new soil corrosion rate probe. The Aquamate Corrater LPR instrument is an electrochemical corrosion rate measurement tool with an added patented Solution Resistance Compensation (SRC) to extend the range of soils in which measurements can be made. The Soil Probe with its replaceable cone shaped tip and rugged construction makes it ideal for field use along new or existing pipelines.

Corrater Soil Corrosion Rate Monitor determines external pipeline corrosion rates

The new Cor-rater Soil Corrosion Rate Monitor measures corrosion rate quickly and easily in a wide range of soils. The monitor allows pipeline operators to quantitatively determine soil corrosivity for the External Corrosion Direct Assessment (ECDA) pre-assessment process, at the time of the pipe excavation or inspection. Determining the level of soil corrosivity before pipeline construction begins allows proper measures to be taken to minimize future replacement and maintenance costs incurred by corrosion damage. The Soil Corrosion Rate Monitor consists of RCS’s portable Corrater Aquamate LPR instrument and the new soil corrosion rate probe.

The Soil Probe, with its replaceable cone shaped tip and rugged construction, is ideal for field use along new or existing pipelines.

CHART RECORDER

The CORD-XL Dual Channel Electronic Chart Recorder is a state-of-the-art electronic chart recording device used to simultaneously monitor and record DC or AC voltages on two electrically isolated input channels. Many other types of signals (such as 4-20 mA transducers) can also be monitored by converting those signals to a voltage value.
