Onsite Machining Services

Saudi Hydrodynamics Co. Ltd. (Saudi Hydro) provides specialized onsite machining services across Saudi Arabia for the oil & gas, petrochemical, power, and industrial sectors. Our field teams are equipped with portable machining systems that deliver workshop-level precision directly at client sites—helping minimize downtime, eliminate heavy transport, and ensure fast restoration during shutdown and turnaround projects.

In-Situ Flange Facing and Surface Restoration

We perform in-situ flange facing and surface machining for heat exchangers, reactors, pressure vessels, and piping systems. Using high-precision portable flange facers, our technicians can restore raised-face, flat-face, or ring-type joint (RTJ) flanges to the required ASME B16.5 / API 6A surface finish. Controlled feed and tool geometry achieve the correct serrated or smooth profile to ensure leak-free sealing performance.

Pneumatic Cold Cutting and Beveling

Saudi Hydro’s cold-cutting service uses advanced split-frame and track-mounted systems to cut and bevel pipes safely in live or hazardous areas where hot work is restricted. The pneumatic setup ensures a spark-free, heat-free operation, suitable for hydrocarbon-containing environments. We perform straight cuts, bevels, compound bevels, and weld-prep machining on carbon steel, stainless steel, and alloy pipelines with precise alignment control.

Diaphragm Cutting and Vessel Opening

Our specialized diaphragm-cutting system enables controlled removal of diaphragms, tube sheets, or internal partitions from process vessels, columns, and heat exchangers. The cutting technique uses high-pressure waterjet or pneumatic cutting tools depending on the application, ensuring clean separation without thermal distortion or contamination. This service is vital during vessel modification, inspection, or cleaning operations and can be performed safely under confined-space or hazardous-zone conditions.

In-Situ Milling, Drilling, and Boring

We offer onsite milling, drilling, tapping, and boring for equipment foundations, pump bases, and mechanical interfaces. Portable milling machines and boring bars allow precision alignment and machining in any plant location, ensuring dimensional accuracy equivalent to shop conditions. These services are ideal for key slotting, bolt-hole pattern correction, and surface re-machining during maintenance or upgrade work.

Line Boring and Alignment Correction

Our portable line-boring units correct wear or misalignment in bearing housings, hinge pins, and rotating equipment supports. The system allows accurate bore restoration without dismantling major assemblies, ensuring minimal downtime and maximum equipment reliability.

Safety, Quality, and Documentation

All onsite machining operations are conducted under strict Saudi Aramco, SABIC, and Royal Commission safety standards. Before mobilization, each job undergoes a site-specific risk assessment (JSA), and all tools are calibrated and inspected. Work results are verified through dimensional inspection, alignment reports, and QA/QC documentation, guaranteeing compliance with client specifications.

With decades of field experience, certified technicians, and the latest portable equipment, Saudi Hydro delivers fast, safe, and precise onsite machining solutions—helping clients restore critical components and resume operations with minimal interruption.
