Products advantages

High dimensional accuracy: Machined to ASME B16.9 standards, with smooth end faces and high coaxiality, ensuring a tight fit with slip-on flanges and reducing the risk of leakage.

Lightweight and high strength: Titanium has approximately 60% the density of carbon steel and its strength is close to or higher than that of carbon steel, effectively reducing pipeline load and making it suitable for weight-sensitive engineering systems.

Multiple size coverage: Covering DN15–DN100 and Sch5s–Sch80, it can match various flange systems and is suitable for chemical, seawater, energy, and fine chemical pipelines.

Production Process

Raw Material Control: Titanium tube blanks conforming to ASTM B363 are selected, and their chemical composition and microstructure are tested.

Forming Process: Seamless forming and hot working processes are employed to ensure uniform wall thickness and dense structure.

Finishing: CNC precision turning of end faces and beveling ensures dimensional accuracy, tolerances, and coaxiality.

Surface Treatment: Acid pickling or sandblasting removes the oxide layer, improving surface cleanliness and corrosion resistance.

Quality Inspection: Dimensional inspection, visual inspection, and material traceability are performed to ensure compliance with standards.
