    When installing a GENIE 750 or GENIE 755 sampling probes, it is not uncommon to experience a slight leak at the stuffing box.

    SOCLEMA explains how to test for leaks at the rod gland, and how to remedy any leaks.

    TheEuropean Pressure Equipment Directive (PED) lays down the essential safety essential safety requirements for the putting into circulation of pressure equipment within the European Economic Area. The version currently in force is Directive 2014/68/EU of the European Parliament and of the Council of May 15, 2014 on the harmonization of the laws of the Member States concerning the making available on the market of pressure equipment. Its first version, Directive 97/23/EC of the European Parliament and of the Council of May 29, 1997 on the approximation of the laws of the Member States concerning pressure equipment, came into force on September 20, 1997.

    The directive applies only to vessels with a maximum pressure PS of over 0.5 bar. It defines two groups of fluids (article 13):

    - group 1: substances and mixtures considered hazardous - explosive, unstable, flammable, oxidizing, pyrophoric, self-reactive, toxic...
    - group 2: other substances and mixtures.

    Depending on the fluid group, the maximum allowable pressure PS - the pressure at which the safety device (valve) triggers - and the volume V, the equipment falls into a risk category, from lowest to highest.

    GENIE sampling probes are subject to this Directive, as their maximum pressure exceeds 0.5 bar. They fall into fluid group 1.

    Article 4 §3 specifies that " pressure equipment and assemblies whose characteristics are less than or equal to the limits referred to in paragraph 1(a), (b) and (c) and paragraph 2 respectively shall be designed and manufactured in accordance with the state of the art in use in a Member State in order to ensure their safe use. Pressure equipment and assemblies must be accompanied by adequate instructions for use." Pressure equipment with a low maximum allowable pressure, a small volume and/or a small nominal diameter therefore falls under the provisions of Article 4 § 3. Such pressure equipment does not have to comply with the essential safety requirements, but only with good engineering practice.

    This is the case for sampling probes and other Geniefilters equipment, which have a small volume and a small nominal diameter.

    Concerning CE marking, Article 4 §3 stipulates: "Without prejudice to other Union harmonization legislation providing for the affixing thereof, such equipment or assemblies shall not bear the CE marking referred to in Article 18."

    This is why Genifilters sampling probes and other equipment, although subject to PED, are not CE marked. In this respect, you will find the certificate issued by A+ Corporation. 

    NB: sampling probes are considered to be pressurized accessories. Article 2 §5 defines pressure accessories as devices with an operational role whose casing is subject to pressure. This means that the device has an operational function other than resisting pressure. The pressure fitting can be attached to other pressure equipment by techniques such as bolting, brazing, soldering or welding. A pressure fitting has one or more operational functions, which may be, for example: measurement, expansion of the fluid being conveyed, sampling, removal of impurities or gases. A pressure fitting does not necessarily have removable parts. Typical examples of pressure accessories are: valves, pressure regulators, measuring chambers, pressure gauges, transparent level gauges, filters, expansion bellows, manifolds.

    For further information, please consult Directive 2014/68/EU on the EUR-Lex website.

    GENIE sampling probes are subject to the European Pressure Equipment Directive 2014/68/EU.

    However, as their volume and nominal size are small, they do not have to meet essential safety requirements, but only good engineering practice. As a result, they do not carry the CE mark (article 4§3).

    For more information, please refer to the question: Are the probes PED-compliant?

    NB: The same rule applies to other geniefilters brand products (separators, filters, regulators), which do not carry the CE mark.

Training courses to learn all about sampling | SOCLEMA

SOCLEMA offers practical training courses on sampling probes.

The training objectives are as follows:

  • Recognize the different types of probes installed on the networks
  • Know the characteristics of these probes
  • Know how to install, extract and reinsert them safely under load
  • Perform simple maintenance
  • Know how to check or diagnose malfunctions or breakdowns on the sampling line.

Training comprises both theory and practice. Practical training is carried out on a pressurized training bench (40 bar) on which operators can practice. In particular, the GENIE GPR, GENIE 701, GENIE 702 and GENIE 755 sampling probes are reviewed.

Each training session lasts 2 days and can accommodate 3 people.

These courses are open to all interested parties, and can be run in either French or English.

Installation of your sampling lines

SOCLEMA can help you with the installation and commissioning of your sampling probes, as well as training your staff.

SOCLEMA's specialized technician will be on hand to assist the technical staff responsible for installation of our pressure sampling systems. He will assist the technical staff in charge of working on this equipment, and explain in detail the various stages involved in installing the sampling probe, right through to starting up the pressurized installation.

SOCLEMA AT YOUR SERVICE FOR ALL YOUR NEEDS

SOCLEMA can also intervene at the customer's request to remove the housing/sampling probe assembly under pressure, for example, when piggings are programmed to pass through the pipe. The SOCLEMA technician works autonomously on site, equipped with the necessary tools.

Maintenance and servicing

SOCLEMA maintains the sampling probes installed:

Complete probe disassembly
Expertise of the probe
Replacement of defective parts
Cleaning of theprobe
Reassembly of the probe

This service can be provided on an ad hoc basis at the customer's request, or as part of a maintenance contract with scheduled periodic checks for a fleet of sampling probes.

SOCLEMA, on the road to sustainable development

Aware that every company, however small, has an impact on the environment, SOCLEMA is committed to sustainable development.

The new building designed by Mr. PERNOT is part of this sustainable development approach, with optimized energy performance thanks to insulation, the use of natural light, the recovery and use of rainwater for sanitary facilities, and the provision of an electric recharging point... All this in a business park offering a green environment where the Communauté de Commune has preserved natural spaces and ecological basins, and installed compost bins...

The second action concerns waste management. In order to reduce waste production, awareness of best practices has been raised: print only when necessary, use as scrap paper a sheet that has only been printed on one side... Without yet going paperless, SOCLEMA has set up an IT tool to store, organize and retrieve all the documents needed for day-to-day operations (quotations, invoices, technical documentation...). The company has also introduced selective sorting of paper, cardboard, glass and other workshop waste.

Finally, we apply this approach to the packaging products we use for our material shipments: reuse or recycling of cardboard, use of eco-responsible packaging, reduced use of plastic packaging...
