All standard sanitary tubing sizes
are available in 1/2″ (12.7 mm) to 8″ (203.2 mm) OD in 20′ (6.1 m) lengths.

Sanitary Stainless Steel Tubing ASTM A270-S2
Mechanical Tests
All testing required by ASTM A270/A1016 is performed. In addition, flare, flatten, flange, and reverse bend
tests are performed. Surface roughness is measured per ASME/ANSI B46.1 requirements. These measurements
are derived from four (4) readings taken at cross sections approximately 90 degrees apart.

Sizes
Diameter: ½” (12.70mm) – 12” (304.8mm)

Thickness
½” (12.70mm) – 3” (76.20mm) = 16 gauge = 0.065” (1.65mm)

Also – Refer to ASME-BPE Standard

Polished tube is manufactured in accordance with ASTM A270 and 3A sanitary standards. Our tubing is made
from cold rolled stainless steel strip whose chemical elements are specially controlled to enhance weldability.
The weld bead is cold-worked to a full finished condition, resulting in a virtually undetectable longitudinal weld.
Bright annealing to 1,900°F minimum follows in a controlled atmosphere to preserve maximum structural integrity.
The tubes are then mechanically polished to a 180 grit (20 μ-in. Ra maximum) interior and 150 grit (32 μ-in. Ra maximum)
exterior finish via state-of-the-art process. Tubes are then line-stenciled with OD, wall, ASTM specifications, grade,
and heat number. Price and weight is per foot.

HIGH PURITY BPE STAINLESS STEEL TUBING
We offers high purity stainless steel tubing that is manufactured to the stringent ASME-BPE and ASTM A270 S2
specifications. This high quality tubing is 100% borescoped and mechanically polished on both the ID and OD.

A270-BPE series tubing significantly reduces customer inspection requirements prior to installation by utilizing
only the highest quality stainless steel materials.

We offers industry-leading sanitary tubing along with technical expertise and unmatched service. We stock all
standard BPE tubing in sizes ½ – 4 inch OD (12.7 – 101.6 millimeter OD) in 20-foot (6.1-meter) lengths.

High purity stainless steel BPE tubing is manufactured to ASME-BPE and ASTM A270 S2 specifications.

SPECIFICATIONS
High purity BPE 316L stainless steel tubing exceeds the requirements of ASME-BPE SF1 and ASTM A270 S2.
All tubing is 100% borescoped and certified to 20 μ-in Ra (0.5 μm) inner diameter (ID) maximum,
and 30 μ-in Ra (0.8 μm) outer diameter (OD) maximum surface roughness. Surface finishes are measured per
ASME/ANSI B46.1, with the profilometer reading at 90 degrees to major polishing pattern.

MECHANICAL TESTS
To ensure the highest surface quality, our sanitary tubing goes beyond the requirements of ASTM A269 and A270
by performing the full battery of ASTM bend and deformation tests required by ASME SA249. The tests, combined
with specific raw material requirements, Eddy Current testing at the tube mill, 100% borescoping prior to mechanical
polish, and tighter OD and wall tolerances, allows for a more consistent, superior quality product.

ANNEALING
Tubing is hydrogen bright annealed in line to 1900°F (1040°C) minimum and rapidly quenched.

CLEANING
A270-BPE high purity tubing ID is thermocouple cleaned per ASTM A632 S3.

PACKAGING
As a final step in maintaining purity standards, A270-BPE tubing is packaged using protective 2 mil poly sleeving
along with air tight plastic end caps.

SURFACE FINISH
We stocks high purity tubing in two finishes: mechanically polished to 20 Ra ID (SF1, or PL) and electropolished
with 15 Ra ID (SF4, or PM). SF1 or PL tubing is mechanically polished to a surface finish of 20 μ-in Ra (0.51 μm) ID
maximum, 30 μ-in Ra (0.8 μm) OD maximum measured per ASME/ANSI B46.1 with the profilometer reading at 90
degrees to major polishing pattern. SF4 or PM tubing is mechanically polished to a surface finish of 20 μ-in Ra (0.51 μm)
ID maximum, 30 μ-in Ra (0.8 μm) OD, then an electropolished for an ID of 15 Ra (.4 μm) maximum.

What is the Difference between ASME BPE Tubing and Standard Sanitary Tubing?
Through our fabrication and installation, we provide a lot of sanitary stainless steel tubing to the food, beverage,
personal care and biopharmaceutical markets. Each piece of tubing can specified by its sanitary surface finish,
tolerance and dimensions. But, have you ever wondered – ‘What is the difference between standard 316L stainless
steel sanitary polished tubing and 316L ASME BPE marked tubing?’
Overview
There was a time when what was considered standard “dairy” type tube and tubing used in the biopharmaceutical
industry were very different. Diary tube had a 32RA ID surface finish. Pharmaceutical tubing usually had much better
surface finishes, somewhere between 25Ra and 10Ra. Tubing with these better surface finishes was usually bought
at a significantly higher price than the 32Ra tube.
Since their initial release in 1997, the ASME BPE standards have become
the standard in the biopharmaceutical industry. The standard designates
6 different acceptable surface finishes, the most common SF1 (maximum
20 Ra) and SF4 (maximum 15Ra+ electropolish). It also designates other
acceptance criteria for surface finishes.
Meanwhile, tubing manufacturers continued to refine their manufacturing processes. A 20Ra ID surface finish used to
be a multi-step, laborious process, now it has become primarily automated. The end result is that the standard polished
“dairy” tube comes with a 20Ra ID finish. No one offers 32Ra tube anymore.
From a metallurgical standpoint, standard 316L and ASME BPE tubing are identical. They are also dimensionally the
same.
So what’s the Difference?
If SF1 ASME BPE tubing and standard 316L sanitary tubing both come with a
20Ra ID polish, why should I pay the premium to buy the BPE tubing? In a
word, insurance. As mentioned above, the ASME BPE standards have
additional acceptance criteria for surfaces finishes beyond simple Ra
readings. They have an extensive list that addresses issues such as pits, nicks,
inclusions and cracks. To ensure that the material meets these standards,
each piece of BPE tubing is visually inspected by boroscope. Does this mean
that the dairy tubing is full of pits and cracks? Absolutely not. But if you
want to be absolutely sure that it does not, the ASME BPE tubing gives you
that.

ASME BPE Guidelines for Pharmaceutical Equipment
What is ASME BPE?
(The American Society of Mechanical Engineers – Bioprocessing Equipment)

The pharmaceutical industry as well as components of a distribution system or conveyor belts, have an
established guideline for their surface finish requirements called ASME-BPE.

ASME-BPE is the leading Standard on how to design and build equipment and systems used in the production
of biopharmaceuticals, which includes bioprocessing, pharmaceutical and personal-care products. The standards
incorporate current best-practices for enhancing product purity and safety and maintain the high levels of hygienic
requirements of the materials used as well as their design, fabrication, and plating methods. Electropolishing has
long supported efforts by ASME, and other organizations, to standardize the expectations and designations of
acceptable surface finishes. our manufacture, is a member of ASME and is currently part of the surface finish
subcommittee for ASME BPE. Learn more about electropolishing

Electropolishing Within ASME BPE Standards
This electropolishing specification includes seven surface finishes that may be used when specifying surface finishes.
The following table summarizes the information provided within ASME BPE for surface finishes of bioprocessing
equipment and distribution system components.
