Sanitary Tubing

QS Certified | #0009870

Wisconsin and the dairy industry are synonymous and United Industries has been involved since the beginning of the modern sanitary and dairy industry. Both industry segments require clean and polished tubing with strict material control and identification. United Industries has provided quality ASTM A270 tubing that meets demanding chemical and manufacturing environments.

Size Range

1/2" – 8"

.019" – .145" wall

Mechanical Tests

United Industries performs all required ASTM A270/A1016 testing. In addition, we also perform flare, flatten, flange, and reverse bend tests. 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.

Finishes

Sanitary A270 (3A) TPV Certified: Bright Annealed, ID-only, OD-only, ID & OD. All mechanical polished tubes meet or exceed A270, 3A, A270-S2,

Packaging

All material is end capped and poly sleeved. Tubes are packaged in tri-wall cardboard boxes with wood ends. Other packaging available upon request. Material Certification is shipped with all tubing. ISO/TS16949:2009 Registered Quality Management System
