Plymouth Tube Company Air 321W Stainless Steel
Tubing
PTCA 321 Welded Stainless Steel Tubing is manufactured by Plymouth Tube Company
Trent. PTCA is an ideal choice when looking for improved interangranular
corrosion resistance, as well as excellent high temperature service in
carbine precipitation range, in addition to being excellent for welding.
Common applications include exhaust manifolds, expansions joints, high
temperature chemical process heat exchanger tubes, and recuperator
tubes.
Remember the only way to Fly with Integrity is to specify PTCA!
