ASME BPE TUBING - Visit our website

We supply Biobore ASME BPE tubing in a number of sizes and with either a mechanically polished or electropolished finish. ASME BPE high purity stainless steel tubing is suitable for use in pharmaceutical, semi-conductor, biotechnology and many other high purity applications. Mechanically polished SF1 tubing is fully boroscoped and polished on both the ID and OD surfaces, thus reducing finish anomalies and minimising the inspection requirement. Electropolished SF4 tubing benefits from an ultra-smooth, corrosion-resistant, chromium enriched surface. It is processed and packaged in a certified ISO Class 5 clean room.
SF1 and SF4 tubing is available from ¼” up to 6” (outside diameter) in 6.1m lengths. Tubing can be cut to length if required. Please contact us for more information.

BIOBORE BENDS - Visit our website

Biobore ASME BPE bends are available in a number of sizes and may have a 45°, 88°, 90° or 92° angle. Like our standard tubing, BPE bends may have either a mechanically or electrically polished finish, depending on the levels of hygiene required.
