| 16 | High Purity Ball Valves | Feitok BGP series three-piece high-purity ball valves are designed to meet the needs of clean dry air (CDA) and bulk gas (Bulk Gas) transportation pipelines for deoiling and degreasing, low working pressure, large flow and two-way circulation. They are widely used in special applications. gas, semiconductor and chemical industries. Operating pressure to 69.0: bar (1000 psig), operating temperature range: -28 °C to 232 °C (-20 °F to 450 °F), internal diameter: 4.6 mm (0.18") to 20.0 mm (0.79 "), standard average inner surface roughness Ra 0.38 μm (15 μin.), helium leakage rate ≤1x10 std cm /s -8 3, end-welded pipe length can be customized |
|
| 17 | High Purity Tubing TBA Series | The TBA series is suitable for high-purity and ultra-high-purity fluid systems in semiconductor and other industries. Strict process specifications are required in terms of materials and production processes, and strict cleaning and packaging processes are used to effectively avoid contaminant residues and meet the semiconductor manufacturing industry's requirements for high cleanliness and high performance of pipe and valve parts. |
|
| 18 | High Purity Tubing TEP and PEP Series | TEP/PEP pipes are suitable for high-purity and ultra-high-purity fluid systems in semiconductor and other industries. Strict process specifications are required in terms of materials, machining, and electrolytic polishing processes, and strict cleaning and packaging processes are used to effectively avoid contaminant residues and meet the semiconductor manufacturing industry's requirements for high cleanliness and high performance of pipe and valve parts. |
|
| 19 | Coaxial Tubing TCA Series | The inner tube is a process tube, which requires strict process specifications in terms of raw materials, electrolytic polishing, cleaning, packaging, etc. to achieve the high cleanliness and high performance requirements of ultra-high purity fluid systems. The outer pipe is a safety pipe. If the inner pipe leaks, the overflowing medium can flow into the safe space. The double-casing system only requires orbital welding installation, which is simple and convenient and can be integrated into existing systems and facilities. |
|
| 20 | Vacuum Generators | Used in gas pipeline systems to assist in system purging and improve purging efficiency. Fully welded design. Ultimate vacuum pressure can reach -93.3 kPa (60 Torr). Various port types are available. |
