Custom Titanium Pipe Spools for Seawater & Desalination 

PETROL STEEL is a provider and exporter of Custom Titanium Pipe Spools for Seawater & Desalination to EPC contractors, engineering companies, procurement teams, and project buyers worldwide who require prefabricated piping for demanding seawater and chloride-containing applications. As part of PETROL STEEL’s Prefabricated Piping & Pipe Spools portfolio, titanium spools offer a specialized solution for applications where piping-system reliability is contingent upon material selection, fabrication quality, and long-term corrosion resistance. PETROL STEEL’s core business is the supply of industrial piping and equipment for oil & gas, petrochemical, and energy EPC projects. Custom Titanium Pipe Spools applies this piping expertise to selected desalination, marine, and water-treatment applications. PETROL STEEL provides fabricated titanium assemblies ready for site installation using approved isometric drawings, MTOs, piping specifications, and project inspection requirements. For international buyers, the emphasis is on practicality: right material, controlled fabrication, documented inspection, reliable delivery, and clear technical communication from RFQ through shipment. 

Titanium Piping for High-Chloride and Seawater Service 

For EPC engineers and procurement managers, the material decision for seawater piping is closely related to chloride exposure, operating conditions, fabrication requirements, and expected service life. PETROL STEEL supplies Titanium Grade 2 (UNS R50400) and Titanium Grade 5/Ti-6Al-4V (UNS R56400), with Grade 7 and Grade 12 available for specific corrosive-service requirements. Titanium is valued in seawater applications for its corrosion resistance, including resistance to localized corrosion in chloride-containing environments. PETROL STEEL therefore approaches titanium pipe spool procurement from the actual project specification rather than treating each seawater line as identical. The technical review may look at material grade, pipe size, wall thickness, spool configuration, welding requirements, flange connections, inspection scope, and applicable codes prior to fabrication. This approach is particularly relevant to SWRO desalination plants, seawater intake and outfall systems, offshore cooling-water systems, and other high-chloride process applications where EPC buyers are demanding a documented material and fabrication solution rather than just a titanium pipe quotation. 

Custom Fabrication from Isometric Drawings 

PETROL STEEL manufactures Custom Titanium Pipe Spools from approved project drawings and specified dimensions, reducing cutting, fit-up, and welding required at the construction site for EPC contractors. Fabrication scope available: CNC plasma or waterjet cutting, automatic beveling, orbital TIG/GTAW welding, and inert-gas shielding with argon backing. Stress-relief heat treatment may be performed as required by the project specification. Standard supply pipe sizes are in the range of approximately ½” to 48″ (DN15-DN1200), and standard wall thicknesses include SCH 5S, 10S, 40S, 80S, 160S, XS, and XXS, and specified custom wall thicknesses. Standard spool length is up to 12 m (40 ft) for containerized shipment; custom lengths can be fabricated from approved isometric drawings. PETROL STEEL also controls the dimensions of the spool according to the agreed project requirements, such as ovality, wall-thickness tolerance, end-to-end dimensions, and flange bolt-hole alignment. This drawing-to-spool approach offers PETROL STEEL’s EPC customers a more controlled pathway from engineering documents to installation-ready piping assemblies. 

Welding, Inspection, and Material Traceability 

The fabrication of titanium calls for careful control of the welding conditions and shielding to prevent contamination of the material and welded joints during fabrication. PETROL STEEL therefore focuses particularly on controlled TIG/GTAW welding, argon backing, and inspection of welded work. 100% visual and dimensional inspection and PT (liquid penetrant testing) or UT (ultrasonic testing) on welds as specified by the project. All Custom Titanium Pipe Spools supplied by PETROL STEEL are subject to internal quality control. PMI (Positive Material Identification) is applicable to base metal and HAZ where required, and RT/MT and hydrostatic testing can be incorporated as per the approved inspection and test requirements. PETROL STEEL can provide EN 10204 3.1/3.2 Material Test Certificates, material traceability, inspection records, and other manufacturing documentation required by purchase order or project ITP. Third-party inspection can also be coordinated if requested by the EPC contractor or end user. Using internal QC along with independent verification, the procurement teams have a documented basis for releasing fabricated titanium piping for shipment. 

International Standards and EPC Documentation 

PETROL STEEL supplies custom Titanium Pipe Spools to the standards and project specifications as identified in the customer’s RFQ and approved technical documents. Typical material specifications are ASTM B337/B338 and ASME SB-337/SB-338, and welding may be to ASME Section IX and AWS D1.9 as applicable. Dimensional and piping requirements can be referred to ASME B16.9, ASME B16.5, and ASME B31.3 depending on spool configuration and project specification. NACE MR0175 may be incorporated when sour service compatibility is specifically required. According to ASME B31.3, it “covers process-piping materials and components as well as design, fabrication, assembly, examination, inspection, and testing,” so clear documentation of these requirements is important for EPC procurement. PETROL STEEL coordinates relevant certificates, inspection records, weld documentation, and final manufacturing records in accordance with agreed project documentation requirements. This discipline of documentation is an important part of PETROL STEEL’s piping supply service for overseas buyers, especially when the finished spools have to pass project inspection before international shipment. 

Applications: Desalination, Marine, and Corrosive Water Systems 

STEEL PETROL Custom Titanium Pipe Spools are designed for specialized service where material selection is a critical engineering consideration for seawater, chlorides, or aggressive marine environments. Typical applications are Seawater Reverse Osmosis (SWRO) desalination plants, seawater intake and outfall systems, offshore platform seawater cooling, power-plant condenser cooling-water lines, chemical processing with chlorides, pulp and paper bleach plants, offshore aquaculture, and marine exhaust-gas scrubbers. PETROL STEEL can supply fabricated titanium piping assemblies for equipment hook-ups, process lines, seawater circulation systems, and other piping areas as required by the project. The benefit of prefabrication for desalination EPC contractors is not only the use of titanium but also the combination of specified titanium material, controlled fabrication, dimensional inspection, and documented quality prior to the spool arriving on the job site. In supporting these specialized seawater and desalination applications, PETROL STEEL applies the same project-oriented piping discipline developed through its oil & gas and energy supply activities.

Request a Custom Titanium Pipe Spool Quotation 

For your next desalination, SWRO, seawater intake/outfall, offshore cooling-water, marine or chloride-service project, PETROL STEEL invites you to submit isometric drawings, MTO/BOM, piping class, material specification, or RFQ for technical review. PETROL STEEL can assess the titanium grade, pipe size, wall thickness, spool dimensions, flange configuration, welding requirements, inspection scope, documentation, and delivery schedule before issuing a commercial quotation. EPC Contractors and Project Buyers can send the available drawings even if the final configuration of the spools has not been completely finalized, and PETROL STEEL’s technical team can identify the information required for the quotation and coordinate the clarification process with the project procurement team. PETROL STEEL offers a controlled supply route from engineering review to sourcing of materials, custom fabrication, internal QC, third-party inspection when required, export packaging, and international shipment. With this dedicated titanium product line, PETROL STEEL takes its proven Oil & Gas Piping Authority to specific high-performance seawater and desalination applications while keeping its fundamental identity as an international industrial piping and energy supply partner.
