NAI-LOK 316L Weld Elbow Pipe Fittings | 90° BPE BA/EP Grade for Pharmaceutical & Semiconductor Piping
 

NAI-LOK 316L Weld Elbow Pipe Fittings is designed for ultra-high purity (UHP) gas and fluid handling systems, where superior cleanliness and corrosion resistance are critical. Manufactured according to ASTM BPE standards, this elbow fitting features bright annealed (BA) and electropolished (EP) internal surface finishes to meet the rigorous demands of semiconductor, biopharmaceutical, and cleanroom applications.

Engineered from SS316L, the fitting ensures excellent durability, chemical compatibility, and smooth internal surface for reduced particle entrapment and superior flow performance. The 90° welded elbow allows for precise directional changes in tubing layout, ideal for compact installation spaces and process control systems.

 

Features
