Our sampling systems are devices or sets of devices used to take samples from a material flow (liquid, solid, or gaseous), such as petroleum or its derivatives, natural gas, or water, from various points within the production, transportation, and refining processes. These samples are then analyzed to evaluate the composition, quality, and performance of the fluids, as well as to monitor the presence of contaminants or other undesirable elements. These systems are widely used in the chemical and petroleum industries to
monitor the quality of petroleum, natural gas, and chemical products.
Sampling systems in the oil and gas industry must meet stringent requirements to ensure accuracy, reliability, and safety. They often include specialized equipment such as samplers, probes, valves, and piping designed to withstand the high pressures, temperatures, and corrosive environments commonly found in oil and gas production facilities.

|---|---|---|
| FLUID PHASE TO BE SAMPLED | FLUID UNDER PRESSURE | NON-PRESSURED FLUID |
| LIQUID | ✔ CYLINDER | ✔ CYLINDER |
| ✘ BOTTLE | ✔ BOTTLE | |
| GASEOUS | ✔ CYLINDER | ✔ CYLINDER |
| ✘ BOTTLE | ✘ BOTTLE | |
Some key considerations in the design and operation of sampling systems for oil and gas applications include:
1. Representative Sampling: Ensure that samples accurately reflect the composition and characteristics of the fluids being produced or processed. This may involve selecting appropriate sampling locations, methods, and frequencies.
2. Contamination Control: Prevent sample contamination from external sources, such as equipment surfaces, ambient air, or other fluid flows, which could skew analytical results.
3. Sample Conditioning: Condition samples to regulate temperature, pressure, or phase (e.g., liquid-vapor equilibrium) to maintain sample integrity and consistency during collection and analysis.
4. Safety: Implement safety protocols and equipment to minimize risks associated with the handling and transport of potentially hazardous fluids, including flammable or toxic materials.
5. Advanced Technology As technology evolves, our sampling systems become
increasingly sophisticated.
Sampling means safely taking a sample from a process or pipeline, preserving the chemical composition during storage or transport for subsequent analysis. Depending on the process stage, temperature, consistency, chemical composition, and other factors, different approaches can be adopted for product sampling.
FLUIDO:
The fluid's liquid-to-gas transition phase at the time of sampling is a critical factor in selecting sampling system components. This is because it directly affects the choice of sample container.
Erre.Di., thanks to its extensive experience in the sector, has developed a sampling system specifically designed for fluids that undergo a phase transition during sampling. This system is equipped with specialized devices that ensure cylinder filling in compliance with current regulations and in complete safety. Depending on the degree of danger of the fluid, specific protection measures are adopted for the operator during sampling operations. These include the use of closed cabinets with transparent tempered glass or plexiglass doors suitable for high temperatures, bottle adapters equipped with vent valves, and the presence of sinks to prevent the dispersion of any drops.
In sampling systems, the materials used for components play a fundamental role in ensuring compatibility with a wide range of aggressive and hazardous fluids. Erre.Di. establishes the use of type 316 stainless steel (SST 316) as its standard. However, upon customer request, alternatives made from materials such as DUPLEX, SUPERDUPLEX, INCONEL 625, INCOLOY 825, and MONEL 400 are available, capable of meeting specific resistance and chemical compatibility requirements.
| MATERIALS SAMPLING SYSTEM | ||
|---|---|---|
| AISI 316/L | UNS S31603 | Widely used in the petroleum and petrochemical industries for its good corrosion resistance. |
| AISI 321 | UNS S32100 | Widely used in applications where a carbide precipitation range between 450 and 850 °C is required. |
| DUPLEX – F51 | UNS S31803 | The most common duplex grade on the market. Excellent resistance to seawater corrosion. |
| INCONEL 825 | UNS N08825 | Resistant to corrosion by acids and alkalis in both oxidizing and reducing conditions. Corrosion resistance in various media, such as phosphoric, nitric, sulfuric, and organic acids, is good. It also exhibits good corrosion resistance in seawater, caustic alkali chlorides, and ammonia. |
| INCONEL 625 | UNS N06625 | The alloy is particularly resistant to pitting and crevice corrosion, as well as to other highly corrosive environments. Operating temperatures range from cryogenic to approximately 1000°C. |
| ALLOY 400 | UNS N04400 | Excellent corrosion resistance in a variety of acidic and alkaline environments. Especially suitable for reducing conditions. Good ductility and thermal conductivity. Excellent for seawater applications. |
TEMPERATURE:
Another key aspect to ensuring correct sampling is fluid temperature. Processes often take place at high temperatures, increasing the risk for operators involved during sampling operations. To mitigate this risk, Erre.Di. recommends using a water-cooled sample cooler and thermal insulation when process temperatures exceed 60°C.
PRESSURE:
Process pressure is a critical component for ensuring proper sampling. Erre.Di. is able to offer solutions even for critical conditions. Through our network of high-quality partners, we can offer fine pressure regulation valves and specific safety devices, such as rupture discs or relief valves, to ensure adequate pressure management during sampling operations.
