QS Certified #0009870
United Industries has been supplying the highest quality tubing for over 80 years.
ASTM A270 tubing meets the demands of the stringent environments in the pharmaceutical and biotechnology industries. Some applications are extremely sensitive and require the highest level of purity. Others have less rigorous standards.
We are now offering two options for BPE tubing that meet SF1 requirements.
- BPE Ultra-Pure: For your most critical applications, ready for electropolishing.
- BPE Pure: Cost-effective alternative when electropolishing is not required.
Made in America with 100% USA steel, you can be assured of the highest quality with either option.

Laser-Welded Tubing For Maximum Performance
Since demanding applications require the highest quality tubing, United Industries has been perfecting its laser welding capabilities since 1992, using a high-energy density process. Our 100% laser welded tubing has:
- Less potential for corrosion in the weld area
- Full finished tube appearance
- Superior performance
