    Equipment for Petrochemicals and Refining

    Petrochemical plants handle flammable fluids at high pressures and temperatures, in ATEX classified zones under Directive 2014/34/EU, where every item of equipment must carry API, ASME or PED certification. We quote API 610 centrifugal pumps, PN100-400 ball valves, safety valves and ATEX process sensors. For a quotation by product code, send the process fluid, flow rate, pressure, temperature and the ATEX zone classification of the installation.

    Frequently asked questions

    ATEX zone 1 vs zone 2: what changes when ordering equipment?

    ATEX zones describe the likelihood of an explosive atmosphere being present: zone 1 means that flammable gas may occur occasionally, in normal operation; zone 2, only rarely and for short periods. Under Directive 2014/34/EU, equipment for zone 1 must be category 2 (marking II 2G), with stricter ignition protection, while zone 2 accepts category 3 (II 3G), usually more affordable in price. When ordering, send us the zone classification from the installation's ATEX documentation, together with the gas group (IIA/IIB/IIC) and the temperature class, so that we can select the correct certification.

    Which standard do centrifugal pumps follow for the transfer of petroleum products?

    For refineries we use pumps built to API 610, the standard dedicated to centrifugal pumps for petroleum, petrochemical products and natural gas. It sets requirements for shaft sealing, materials resistant to corrosion and process temperature, minimum clearances for maintenance and performance tests (hydrostatic, NPSH). We also check the compatibility of the mechanical seal with the pumped fluid, often to API 682. For an order we need the flow rate, discharge pressure, density and viscosity of the fluid, the operating temperature and whether the installation is ATEX classified.

    What nominal pressures (PN) and ANSI classes do ball valves for refinery lines cover?

    The ball valves in our range cover PN100 to PN400 (roughly equivalent to ANSI classes 600-2500), with metal-to-metal sealing for high temperatures, where soft PTFE seals no longer withstand them. The class is chosen according to the maximum design pressure of the line and the fluid temperature - an undersized pressure rating is a safety risk, an oversized one means unnecessary cost. For hot or abrasive fluids we recommend valves with a “fire-safe” design tested to API 607/API 6FA. Send us the line data sheet (P&ID) with the design pressure and temperature.

    What certifications do safety valves for boilers and pressure vessels have?

    The safety valves we supply are TÜV-certified or conform to ASME (section VIII for pressure vessels), with tested discharge capacity and CE marking under Pressure Equipment Directive 2014/68/EU. Correct sizing depends on the set pressure, the required discharge flow and the fluid protected (gas, vapour or liquid). An undersized valve does not protect the installation, and an oversized one can cause chattering (rapid opening and closing), which destroys the valve seat. Send us the set pressure and the vessel data for suitable selection.

    What information should we send for a quotation on equipment for a refinery?

    We need: the process fluid (composition, density, viscosity, solids content), the process parameters (flow rate, pressure, minimum/maximum temperature), the ATEX zone classification if any, the material required or specified in the tender documents and the reference standard (API, ASME, EN). If you have the P&ID or the data sheet of the existing equipment, it helps a great deal in identifying a compatible replacement. The lead time is 24–72 h when the item is available locally or at the supplier; to order, usually 1–4 weeks; it may take longer depending on the brand and the specifications.
