Aquaculture
Aquaculture equipment can expose fasteners and components to saltwater, disinfection and cleaning chemicals, biofouling and continuous outdoor service. We help buyers define a titanium RFQ around the actual equipment, its mating materials and the maintenance need.
Applications / 01
These areas are starting points for engineering review. Any titanium part must meet the equipment drawing, the operator's requirements and the actual water and cleaning conditions.
External mounting fasteners and approved small parts for civil hatchery equipment can be reviewed once salinity, temperature and cleaning exposure are defined. Process-wetted equipment parts are outside our scope.
Fixings for walkways, feed lines, cameras and sensor mounts can be reviewed against loads, wave and vibration exposure, and the materials they connect to. Mooring components follow their own design rules.
External frame, guard and instrument-bracket fasteners for civil seawater service systems can be reviewed against the equipment drawing and any OEM-approved material list. Fluid-path components are outside our scope.
Service conditions and checks
Grade 2 is our commercial sourcing focus; other grades are reviewed only when the drawing or specification calls for them, with the supplier route and its scope confirmed first. The summaries below help define the RFQ. They are not a material approval; suitability for a specific system remains the responsibility of the equipment designer or qualified engineering team.

| Condition | Why it matters | What to state in the RFQ |
|---|---|---|
| Water | Seawater, brackish and recirculated water differ in salinity, temperature and chemistry, and recirculation can concentrate dissolved species. | Water type, salinity range, temperature range and whether the system recirculates. |
| Disinfection and cleaning | Dosing and cleaning can expose parts to a different chemistry from the bulk water. Compatibility depends on the chemical, concentration, temperature and contact time. | Each chemical, concentration, temperature, contact time and cleaning frequency. |
| Mechanical exposure | Wave action, vibration and handling loads affect fastener preload, locking and fatigue. | Loads, vibration sources, locking method and any fatigue requirements. |
| Mating materials | Aquaculture equipment often combines aluminium, galvanized or stainless steel, HDPE and composites. | Every material the titanium part touches, including washers, sleeves and coatings. |
Beyond the service conditions, four design checks often decide whether a titanium fastener or small part is appropriate.

| Check | Why it matters | What to tell us |
|---|---|---|
| Galvanic contact | Titanium coupled to aluminium, zinc-coated or carbon steel in seawater can accelerate corrosion of the less noble metal, especially when its exposed area is small. | Every mating material, relative areas and any project-specified isolation. |
| Crevices and clamps | Tight crevices under washers, clamps and gaskets need review of temperature, chemistry and joint geometry, particularly in warm recirculated water. | Joint and clamp design, water temperature and any specified alternative grade. |
| Polymer and composite joints | Fasteners in HDPE or composite structures depend on clamp load, washer area and the material's creep behaviour, not only on corrosion resistance. | Structure material, clamp load or torque requirement and washer specification. |
| Biofouling and maintenance | Marine growth can occur on titanium surfaces immersed in seawater. Cleaning access and the specified cleaning method still matter for the joint and its threads. | Cleaning method and frequency, and whether parts must be removable for maintenance. |

Supply boundary
Our sourcing scope is civil-use external fixings and approved drawing-based small parts. Process-wetted pump and valve components, heat-exchanger tubes or plates, and reactor or agitator internals are outside our advertised supply scope. The actual part, destination, end user and end use must be reviewed before order acceptance; an external fastener is not automatically exempt from export controls.
Read our civil-use and export scope before preparing an enquiry.
Scope / 02
Use this page to prepare the sourcing conversation. Material selection and final design suitability remain the responsibility of the qualified project team and applicable specification.
Identify the civil equipment and the external fixing or support function. Fluid-path equipment components are outside our sourcing scope.
Share the water, chemicals, temperature, loads and maintenance cycle relevant to the part.
List the structure and hardware materials the part will touch, including washers, sleeves and coatings.
Provide the drawing, standard, grade, dimensions, quantity and required date.
Say whether parts must be removable for cleaning or replacement, and how often.
Agree certificates, traceability and inspection that are proportionate to the equipment requirement.
Working note
A drawing, BOM line or material specification with quantity, required date, destination and documentation needs is enough for an initial feasibility review. Separate fasteners from machined parts so each item has a clear acceptance scope.
We work through the Baoji titanium supply chain and confirm the proposed supplier route, documentation and inspection scope before you commit. Availability, minimum quantity and delivery are stated in the quotation for each requirement. The release-document checklist helps define the evidence your project needs.
Buying questions
Short answers for aquaculture equipment makers, farm maintenance teams and integrators preparing a titanium enquiry.
Commercially pure titanium is widely associated with seawater corrosion resistance, but each joint still depends on water chemistry, temperature, cleaning chemicals, crevices, loads and mating materials. The equipment designer or qualified engineering team decides suitability; MetalPartSource sources against that approved requirement.
They can accelerate corrosion of the aluminium or zinc coating if the metals are electrically connected in seawater, especially where the less noble metal's exposed area is small. The project team should define any isolation or coating. List the mating materials in the RFQ.
Yes. Ozone, chlorine or hypochlorite dosing and periodic cleaning chemicals can differ from the bulk water. State each chemical, its concentration, contact time and frequency so the specification can be checked against the actual service.
Material test certificates (EN 10204 3.1 where applicable), heat or lot traceability and dimensional inspection can be requested in proportion to the equipment requirement. Availability and scope are confirmed for each supply route and order before commitment.
Use the custom titanium component page for a machined drawing-based part, or the titanium fastener sourcing page for specified hardware. Submit either requirement through the RFQ desk.
