Titanium stub ends

Titanium Stub Ends – Premium Corrosion-Resistant Piping Solution

LINHUI TITANIUM manufactures precision-engineered Titanium stub ends compliant with ASTM B363 and ASME B16.9 standards. Our stub ends feature customizable specifications with titanium content reaching 99.95% purity and particle granularity controlled between 149–420μm.

The smooth pure titanium gray surface finish ensures optimal gasket seating. These products are designed for lap joint flange assemblies, providing cost-efficient corrosion resistance by limiting expensive titanium to wetted surfaces while using carbon steel backing flanges. This hybrid approach reduces material costs by 40-60% compared to solid titanium flanges.

With density at 4.51 g/cm³—60% lighter than steel—our products deliver exceptional strength-to-weight ratios ideal for offshore platforms and weight-sensitive installations.

Key Features & Benefits

Superior Corrosion Resistance

Self-healing TiO₂ passive film prevents pitting and stress corrosion cracking in chloride environments, outperforming 316L stainless steel.

Cost-Effective Design

Hybrid construction isolates corrosive media from affordable backing flanges, reducing project expenses significantly.

Lightweight Strength

40% lighter than steel equivalents, reducing structural loads in marine and aerospace applications.

Easy Alignment

Rotating backing flanges simplify field installation and eliminate torsional stress during bolt-up operations.

Product Information

Manufacturing Process

Fabric Selection

High-purity titanium billets sourced with full warm traceability documentation.

Hot Forming

Controlled manufacturing at 800-950°C shapes the lap confront and barrel geometry per dimensional standards.

Machining

CNC exactness turning accomplishes tight resistances (±0.05mm) on fixing surfaces and weld bevels.

Heat Treatment

Stress help tempering at 650-750°C guarantees dimensional solidness and dispenses with remaining stresses.

Surface Treatment

Pickling in HNO₃-HF arrangement evacuates scale; discretionary electropolishing improves finish.

Quality Inspection

· 100% dimensional confirmation utilizing CMM equipment

· Ultrasonic testing (UT) per ASTM E213 for inside defects

· Liquid penetrant assessment (PT) on fixing faces

· Chemical composition investigation by means of spectrometer

· Hydrostatic testing accessible on request

· EN 10204 3.1/3.2 fabric test certificates

· Third-party assessment bolster (SGS, BV, TÜV)

Applications

Chemical Processing

Handles damp chlorine, hypochlorites, and solid oxidizers in dying circuits where stainless steel erodes rapidly.

Desalination Plants

MSF and RO frameworks advantage from erosion-corrosion resistance in high-velocity seawater piping.

Offshore Oil & Gas

FPSO fire water and balance frameworks require lightweight, life-of-field solidness against marine atmospheres.

Power Generation

Cooling water frameworks in coastal plants anticipate biofouling and keep up warm exchange effectiveness.

FAQ

Q: Can carbon steel ribs be utilized with your stub ends?

A: Yes, that's the essential plan. The titanium stub conclusion separates destructive media from the carbon steel backing flange.

Q: What's the distinction between Sort A and Sort B?

A: Sort A has a radiused corner coordinating lap joint ribs; Sort B has a square corner for slip-on backers.

Q: How do you anticipate oxidation amid welding?

A: Argon cleansing on both burn and root sides shields the weld zone until it cools underneath 426°C.

Q: Why select Review 7 over Review 2?

A: Review 7's palladium expansion amplifies benefit life in decreasing acids like HCl and raises hole erosion edges.
