- ASME BPE
The American Society of Mechanical Engineers have developed
a standard for Tubing and Fittings used in the Pharmaceutical
Industry (ASME Bioprocessing Equipment). This covers all
aspects of the manufacturing process including finishes,
tolerances and dimensions.
Items covered by this standard are identified with the
respective Table No. i.e. 90 Deg. Bend WW Table DT-7.
- ISO QUALITY SYSTEM
To ensure that we constantly maintain the standards stated
our manufacturing and Quality System conforms to ISO 9001-2000.
SFL have a continual commitment to quality and the system
is audited internally and externally.
- PRODUCT RANGE
Product range covers sizes from 1/4” O.D. to 6”
O.D. in tubing, weld end fittings suitable for orbital
welding and clamp ended fittings.
- DIMENSIONAL TOLERANCES
Tolerances on weld ended products are suitable for closed
head orbital welding. Tolerances on squareness and wall
thickness
comply with ASME BPE.
- SURFACE FINISH
Choice of
mechanical finish and electropolished finish on I.D. Finish on O.D.
to suit customers requirements either Mill finish or sateen
polished.See table below for surface finish designations for tube and fittings.
- CONTROLLED CHEMICAL ANALYSIS
All contact parts are manufactured from T316L quality
materials. Sulphur is controlled at weld point to 0.005%
minimum and 0.017% maximum to ensure good quality orbital
welds. Part of our Quality Control is to check that the
raw materials purchased conform to the Chemical Analysis
stated on the Material Certificate, this is carried out
by an independent laboratory.
- TRACEABILITY
All materials are traceable back to the original Material
Certificates. To ensure full traceability SFL mark all
T316L products with an internal reference number
in addition to their cast/heat number.
- MARKINGS
All products are marked with cast/heat number, internal reference number
number, ASME BPE table number and SFL logo.
- PACKAGING
Tubing is supplied with ends capped and sleeved in polythene,
end heat sealed. Fittings are capped and heat sealed in
polythene.
