Sanitary Fittings

Ultra-Clean, Exceptionally Smooth Surfaces and Corrosion Resistant

We offer Ultra High Purity (UHP) stainless steel tubing that is ideal for the biotech and other industries where ultra-cleanliness and extraordinarily smooth surfaces are required for product purity and flow characteristics.  These fittings are produced in accordance with ASTM and ASME applicable standards. All surface finishes are measured to ANSI B46.1 standards and meet or exceed the requirements of ASME-BPE SF1 through SF6.

Sanitary Tubing Specifications

ASME-BPE compliant SFT1 through SFT6 stainless steel sanitary tubing and fittings are produced in accordance with the requirements of ASTM A270-S2 and the newest ASME-BPE standard for manufacturing process, testing, tolerances and surface finishes. Tubes are bright annealed and rapidly quenched in accordance with the specifications. We carry seamless products from 1/16” to 2” and welded sizes from 1” to 8”, and can help with your metric and DIN sizes.

Chemical Composition

Our sanitary tubing is available in alloys 304/304L and 316/316L.  All 316/316L tube is supplied with a sulfur content of .005 – .017% as specified in ASTM A270, Supp. S2.1.1. for welded tubing and the sulfur content for seamless is .005 – .012%.

Mechanical and Electropolished Finishes Available

Electropolishing is an electrochemical method where a surface layer of approximately 20µm is removed.  The removal primarily takes place on the tops of the micro profile.

The austenitic structure appears in a very clean condition. The surface has a bright and shiny appearance.

Consistent Dimensional Control and End Finishing for Ease of Installation and Orbital Welding

These products meet or exceed ASME BPE Part DT.
