    Equipment for the Energy Sector

    Power plants and heat substations operate with steam and heating medium at strict pressure and temperature parameters, where pressure vessels fall under ISCIR inspections and Directive 2014/68/EU. We supply boiler feed pumps, steam valves, steam traps, certified safety valves and heat exchangers. Send the pressure, the temperature, the steam flow rate and whether the installation is subject to ISCIR inspections.

    Frequently asked questions

    Which valves are used on high-pressure steam lines and which standards matter?

    For steam at high parameters (up to about 550°C and 400 bar in our applications) we use valves with metal-to-metal sealing and an alloy steel body resistant to thermal creep, sized by the PN or ANSI class matching the line's design pressure and temperature, not just the current operating pressure. The valves must be tested to EN 12266 or API 598, and for critical services we recommend welded-bonnet construction, without gaskets that can fail under repeated thermal cycling. Send us the maximum design pressure and temperature, plus the type of actuation you want.

    What is the role of steam traps and how do I choose them?

    A steam trap automatically discharges condensate from the steam network without letting live steam through - faulty operation means either energy losses or stagnant water that causes water hammer and corrosion. The choice depends on the application: thermodynamic traps for distribution with variable flow, float traps for heat exchangers where continuous discharge is critical, and bimetallic traps for drainage with subcooling. Capacity is sized from the estimated condensate flow and the available differential pressure - send us these data for the right recommendation.

    What certifications must a safety valve for an industrial boiler have?

    A boiler safety valve must be certified under the Pressure Equipment Directive 2014/68/EU (CE marking with the notified body number) or, where explicitly required, TÜV tested. The discharge capacity is sized from the boiler's maximum steam flow and the set pressure, according to the ISCIR technical requirements applicable to pressure installations in Romania. A valve that is wrongly sized or installed is a frequent reason for rejection at the periodic ISCIR inspection. We supply valves with the certification documentation needed for commissioning and periodic inspections.

    What should be checked on a heat exchanger for a heat substation?

    For heat substations and domestic hot water preparation, the plate exchanger is sized from the required thermal load (kW), the inlet/outlet temperatures on both circuits and the permitted pressure drop. The plate material (316 stainless steel or titanium for water with aggressive chlorine) and the gasket type must be chosen according to water quality - scale deposits or corrosion drastically reduce efficiency over time. We recommend a periodic cleaning strategy (CIP or mechanical dismantling) set from the design stage, so that you do not lose thermal capacity year after year without knowing why.

    What information do you need for a quote on equipment for a power plant or heat substation?

    Please send the steam or heating medium parameters (pressure, temperature, flow rate), the P&ID diagram if one exists, the type of fuel or energy source and whether the equipment replaces an existing one (model, year of manufacture, problems encountered). For boilers and pressure vessels, state whether the installation is subject to ISCIR inspections. With these data we prepare a quote with full specifications - for consumable parts (gaskets, steam trap elements) the lead time is 24–72 h when the item is available locally or at the supplier, and for new equipment made to order, usually 1–4 weeks; it may take longer depending on the brand and the specifications.
