Temperature is one of the most important controllable factors affecting corrosion rate, particularly in refineries, chemical, and petrochemical process plants. A rule of thumb is that corrosion rates double for each 10 degrees C temperature rise. The ability to track temperature and corrosion rates simultaneously is a powerful tool in the corrosion management of such plants.
Electrical Resistance and ER Temperature probes are designed for safe installation and operation in various environments. Certain accessories are required based on pressure, temperature, etc.
Model 2700 and 2705 fixed process probes have a flat strip measuring element sealed and mounted at the end of a heavy walled stainless steel tube. The measuring element can be positioned flush with the inner surface of the pipe or vessel. Corrosion or erosion can then be measured right at this surface, and the lines may be pigged without moving the probes.
Model 2500 fixed process probes have a thin walled cylindrical sensing element which is welded onto a body of the same material. No other materials are in contact with the corrosive medium. Welds are vacuum annealed during assembly to avoid preferential corrosion effects.
Model 2520 fixed process probes are designed for particularly severe or toxic duty service, where retractable or fixed thread probes are not permitted by plant or other regulations.
Model 620HD and 650 ER probes are designed for underground and structural monitoring of pipelines, vessels, above and below ground storage tanks and structures — whether cathodically protected or not.
Cosasco Bio-Probes for the 2″ system are used to suspend sample elements in the area to be monitored. Attached to the bottom of the solid plug by means of a left handed thread, the bio-probe also serves as a primary packing retainer.
This probe employs two identical electrodes which are mounted at the end of the probe by threaded, insulated, glass-sealed studs. The glass seals provide high pressure integrity. The probe is sealed into the hollow plug of the access fitting with a ceramic filled teflon seal.
LPR and Temperature LPR probes are designed for safe installation and operation in various environments. Where danger of blowout exists, use of an appropriate safety device should be considered mandatory. This equipment is designed and tested for reliability, using established principles of operation.
This LPR probe model is ideally suited for laboratory testing or light duty plant operations in a bypass rack where removal under system pressure is not required. For heavier duty plant operation see Model 7012 or 7022.
The Model 7012/7022 LPR Probe provides a more rugged construction and is ideal for plant use in a bypass rack where removal under pressure is not required. This LPR probe employs two replaceable, identical electrodes which are mounted at the end of the probe by threaded, insulated studs.
This probe employs two identical electrodes which are mounted at the end of the probe by threaded, insulated studs. The glass reinforced epoxy electrode header used on the Model 7212 provides insulation and is preferred at high pH ranges over the glass sealed Model 7222.
Cosasco offers a range of metal loss sensors and instrumentation, designed specifically to detect sand erosion at speeds approaching real-time. Sensing elements for the erosion/corrosion measurement system can be made from almost any commercially available, alloy.
Microcor® ER Probes are an integral component of the new high-resolution Microcor® system. Special design of the probes provides advanced thermal performance and reliable operation in all environments including sour service.
Model 3500 Probes provide a large test surface, excellent dynamic temperature response and protection of reference element.They are ideally suited to the more aggressive plant conditions and may be used in very aggressive organic or inorganic fluids over the entire pH range 0-14, subject to process containment requirements.
Model 3520 retractable process probes are designed for particularly severe or toxic duty service, where fixed thread probes are not permitted by plant or other regulations.
Model 3700 and 3705 retractable process probes have a flat strip measuring element sealed and mounted at the end of a heavy walled stainless steel tube. By adjusting the position of the probe or proper selection of the physical dimensions of the coupling system, the measuring element can be positioned flush with the inner surface of the pipe or vessel.
These Models are ideal for direct mounting into plant pipework or vessels and allow insertion or removal while under system pressure. The electrode seals are suitable for all pH ranges. These probes employ two replaceable, identical electrodes which are mounted at the end of the probe by threaded, insulated studs.
Model 3504 Retractable Process Probes are ideally suited to the more aggressive plant conditions and may be used in very aggressive organic or inorganic fluids over the entire pH range 0-14, subject to process containment requirements. These probes are standard in mild steel, 304 S.S. and 316 S.S..
Model 4700 probe is available with a durable construction incorporating a connector with shrouded pins to prevent accidental damage. This high pressure probe with element thicknesses up to 40 mils, can be read by any Electrical Resistance (ER) corrosion monitoring instrument.
Model 4705 probe is available with a durable construction incorporating a connector with shrouded pins to prevent accident damage. It is recommended for all new installations. This new style incorporates welded shields where required and requires a different probe connecting adaptor (see order details).
Model 4500 probe is available with a durable construction and incorporating a connector with shrouded pins to prevent accidental damage. It is recommended for all new installations. This new style incorporates welded shields where required and requires a different probe connecting adaptor (see order details).
Sand production in oil and gas producing wells can cause rapid erosion and wear of top side equipment such as chokes, valves, and flow-lines. The areas that can experience the most severe effects of erosion are immediately downstream of a choke, outer diameters of bends, reducers, misaligned flange joints and pipe T joints.
