What is Tank Internals, Heating & Agitation Systems?
🌡️ Tank Internals, Heating & Agitation Systems represents a complete system of precision titanium components engineered for Electroplating & Surface Finishing applications. Thin-wall tubular heater sheaths and steam coils, perforated sparger pipes, venturi eductor nozzles, thermowell sleeves, float switch balls, weir overflow plates The system integrates 7 distinct component types manufactured through 3 specialized processes.
Key manufacturing processes for this system include CNC machining CP Ti for tank hardware geometry, TIG welding Ti filler with 0.5mm corner radius, Pickling and passivation with 0.5mm corner radius, Continuity test <1 mOhm with 0.5mm corner radius, TIG welding Ti filler with SPC sampling, each selected and qualified to meet component-specific requirements.
Engineering & Design Principles
Material: Grade 2 (CP-Ti) thin-wall seamless tube for heater sheaths and steam coils provides excellent heat transfer with total corrosion immunity. Grade 5 for eductor nozzles requiring high erosion resistance
Form: Seamless thin-wall tube for heater sheaths and steam coils. Tube drilling for sparger pipes. CNC machining for nozzle orifices. Sheet metal forming for weir overflows.
Standards & Material Specifications
Standards: ASTM B338 Grade 2 seamless tube (heater/coil) / ASTM B348 Grade 5 (nozzles), 100% pressure tested

1 Part Feature Analysis
Large-section forged struts, links, and beams with complex internal bores, trunnion pins, and lug attachments
- ⚠️ Ultra-high tensile and compressive stress during landing
- ⚠️ Stress corrosion cracking from runway de-icing chemicals
- ⚠️ Impact fatigue from repeated landing cycles
- ⚠️ Weight reduction for fuel economy
2 Material Selection Rationale
Ti-1023 (Ti-10V-2Fe-3Al) — Beta alloy, ultra-high strength >1100MPa, high fracture toughness
Ti-1023 (Ti-10V-2Fe-3Al) offers >1100MPa yield strength with high fracture toughness (>60 MPa·m^1/2) for landing gear. Replaces high-strength steel at 40% weight saving. Beta-annealed for optimal SCC resistance.
3 Form Selection Rationale
Die Forging / Ring — for high-stress critical parts
Large press closed-die forging is mandatory for landing gear structural parts. Grain flow must follow the part contour for optimal fatigue life. Finish machining after heat treatment.

Process Pitfalls:
- ⚠️ Ti-1023 is sensitive to inclusions — VAR double-melt mandatory for all landing gear stock
- ⚠️ Lug hole surface finish must be Ra<0.8um to prevent fatigue crack initiation under cyclic tension
