Industrial
One specification-first sourcing operation, engineered for heavy industry worldwide. Whether the line item is a control valve for a refinery revamp or a gearbox for a mine conveyor, the workflow is the same: written RFQ, qualified suppliers, documented quality, coordinated delivery.
Oil & Gas Refining
Turnarounds, unit revamps and day-to-day MRO for refineries and terminals — piping, valves, gaskets, instrumentation and analyzers supplied against refinery piping classes and shutdown deadlines.
Petrochemical & Chemical
Corrosion-resistant alloys, sealing systems, rotating equipment and process analyzers for aggressive media — delivered with the material traceability process licensors and owners expect.
Pipelines & Gas Transmission
Line pipe, induction bends, pipeline valves, pig traps, metering and cathodic-protection materials for liquids and gas transmission systems, compressor and pump stations.
Upstream & Drilling
OCTG, wellhead components, drilling consumables and high-pressure flexibles for onshore and offshore exploration and production — to API monogram requirements where applicable.
Power Generation
Boiler tubing, high-energy piping, valves, heat-exchanger spares and instrumentation for thermal, combined-cycle and renewable plants — including chrome-moly grades for high-temperature service.
Water & Wastewater
Pumps, dosing systems, ductile and stainless piping, valves and liquid analyzers for municipal and industrial treatment plants, desalination and produced-water handling.
Steel, Metals & Mining
Slurry pumps, wear parts, conveyors, gearboxes, hydraulics and heavy-duty electrical materials for mines, concentrators, smelters and steel mills — matched to OEM part numbers.
Industrial Laboratories
Fuel-testing instruments, spectrometers, titrators, glassware and consumables for refinery, petrochemical and plant QC laboratories — including spares for installed instrument fleets.
General Manufacturing
Compressed air, motors, bearings, power transmission, maintenance consumables and safety supplies for food, pharmaceutical and discrete manufacturing plants — consolidated into single shipments.
Built for specification-driven buyers
Rastemex serves procurement teams, maintenance planners and EPC buyers who purchase against datasheets, standards and part numbers — not from a shelf. That is why every sector above is quoted through the same documented RFQ workflow.
Project supply
Bills of materials for new construction and expansion projects, priced from multiple markets and staged to your construction schedule.
Turnaround & shutdown
Time-critical packages for planned outages, with expediting and documentation tracked line by line until delivery.
MRO & spares
Recurring consumables and OEM spare parts consolidated under one commercial contact, quoted item by item on request.
