KF Vacuum Straight Pipe
This is a KF Vacuum Straight Pipe (also called Vacuum Extension Spool / KF Flange Nipple), precision-manufactured from high-grade stainless steel (304 or 316L). Designed for quick connection via KF flanges, it serves as a key component in vacuum systems to extend pipeline length or connect different parts, ensuring leak-tight assembly and stable vacuum performance.
KF Vacuum Straight Pipe
Key Features
- Leak-Tight Vacuum Performance: Seamless body and precision-machined KF flanges ensure excellent air-tightness, suitable for high and ultra-high vacuum applications.
- Premium Material: Made of 304/316L stainless steel, offering outstanding corrosion resistance, rust-proof property, and durability for long-term use.
- Precision Machining: Strict dimensional control guarantees perfect fit with KF clamps and centering rings, eliminating assembly errors.
- Easy Installation: KF flange design allows quick, tool-free assembly/disassembly for convenient system maintenance and modification.
- Customizable Length: Available in standard sizes (KF16/KF25/KF40/KF50) and custom lengths to meet diverse vacuum system layout requirements.
- Smooth Inner Surface: Polished interior minimizes gas adsorption and ensures clean flow paths, ideal for cleanroom and high-purity applications.
