Ameritube moved into chemical processing in 2013 supplying copper-nickel to Gulf Coast plants whose brass bundles kept failing. Today we supply the whole corrosion ladder, from 316L to C-276, with the acid, chloride, and caustic experience to tell you where each one stops working.

Ameritube supplied SA789 duplex 2205 U-bends with controlled bend heat treatment and ferrite verification. The bundle is still in service. Read the full case study in the PDF. ## Why chemical plants use Ameritube - The copper-nickel is drawn and tested here, so lead time is measured in weeks. - We have seen the failure modes and will steer you off the wrong alloy before you buy it. - One supplier for the whole corrosion ladder, one documentation format, one phone number. **What to include in your RFQ**Alloy, OD, wall, length or U-bend schedule, quantity, the process fluid with concentration and temperature, the cooling water chemistry, and any corrosion test (A262, G28, G48) or PMI your specification calls for. If you are not sure which alloy, send the conditions and we will recommend one. Request a quote ## Quote chemical processing tube. Alloy, OD, wall, length, quantity, and the standard.
