What Seps, A.s. does

SEPS, a.s. is a Slovak joint-stock company (akciová spoločnosť), founded in 1996 and registered in Bratislava, that provides specialized diagnostic, repair, and maintenance services for industrial pipelines operating under pressure without shutdown. The company's core activity is "za prevádzky" (on-line) work — interventions on pipelines carrying water, gas, oil, steam, chemicals, and product media while they remain pressurized, eliminating costly plant outages for asset owners in the energy, petrochemical, oil & gas, water utility, and district heating sectors.

The technical platform is built around a mobile accredited NDT laboratory (SNAS-accredited per EN ISO/IEC 17025) executing standard methods (VT, PT, MT, RT, UT, UTT) and advanced methods (TOFD, Phased Array, EMAT, PEC, SLOFEC, Guided Waves), supplemented by Pure Technologies' SmartBall® and Sahara® internal inspection tools, T.D. Williamson hot-tapping and line-stopping equipment (STOPPLE, SHORTSTOP, STEELSTOPP, drilling machines T-101 through TM 2460), PLIDCO mechanical and welded repair clamps, and HYTORC hydraulic torqueing. Service lines span pipeline integrity assessment (RBI per API RP 580/581, defect evaluation per ASME B31.G/RSTRENG/DNV-RP-F101), on-line welding (EN ISO 3834-2, supervised by IWE/EWE engineers), pressure repair / stress testing capable of extending pipeline life by 20+ years, internal cleaning and decontamination, and emergency response. The company operates an emergency hotline and "Centrum rýchlej pomoci" (Rapid Help Center).

SEPS monetizes through project-based professional services contracts and product sales (cleaning pigs, drilling machines, isolation equipment, fittings, PLIDCO clamps). Pricing is quote-based and non-public. Customers are reached via direct enterprise field sales to operations and maintenance decision-makers in Slovakia and the EU, supported by membership in the Slovak Gas and Oil Association (SGOA), the Slovak Maintenance Society (SSU), and the Maintenance, Production and Assembly Society of Chemical, Pharmaceutical and Paper Industry (SÚZ). The company carries EUR 2M per-claim / EUR 4M annual aggregate liability coverage with HDI Versicherung AG (Vienna) and is certified to ISO 9001, ISO 14001, ISO 45001, SCC**, EN ISO 3834-2, and EN ISO/IEC 17025.

• PICA Pipeline Inspection: PICA Pipeline Inspection provides internal pipeline inspection, leak detection, and pipeline cleaning services — overlapping SEPS's SmartBall/Sahara service line, internal pipeline inspection, and cleaning pig operations.
• STATS Group: STATS Group provides pipeline isolation, hot tapping, and intervention services across oil, gas, and petrochemical sectors globally. It competes directly with SEPS for the same niche in-service pipeline work and shares comparable technology partnerships and certification frameworks.
• Quest Integrity Group: Quest Integrity specializes in advanced NDT inspection, RBI, fitness-for-service assessment, and pipeline integrity engineering — closely matching SEPS's diagnostic-to-assessment service portfolio and target customers in refineries and petrochemical facilities.

Broad incumbents

• Penspen: Penspen is an established pipeline integrity and engineering services firm serving oil, gas, and refined product operators worldwide with RBI, corrosion assessment, and fitness-for-service work overlapping SEPS's assessment services.
• Pure Technologies (Xylem): Pure Technologies, now part of Xylem, is the originator of SmartBall and Sahara leak detection technologies licensed to SEPS. It is the dominant water-pipeline inspection specialist in North America and competes globally for the same municipal/utility inspection work.
• TWI (The Welding Institute): TWI provides welding technology research, certification, and pipeline-related engineering services — overlapping SEPS's welding coordination (ISO 3834-2) and welding procedure qualification work, with much broader global reach.
• Rosen Group (Baker Hughes): Rosen is a global leader in pipeline inspection, integrity management, and in-line inspection services across oil, gas, water, and refined product pipelines. As a Broad Incumbent, it competes with SEPS on the integrity/inspection side but operates at significantly greater scale across all of Europe and globally.
