Why is a composite plate of S30408 + Q345R used as the main material for the debutanization tower, with a design pressure of 2.6 MPa and a design temperature of 300 degrees?
Composite panels are prone to delamination at high temperatures; surfacing welding is recommended
The medium contains sulfides; using composite plates is no problem at a design temperature of 300 degrees, while cladding should be considered for temperatures above 450 degrees.
Won’t this temperature pull out C5 and C6? ?
Reduce costs while preventing corrosion
If it is for corrosion resistance, is heat treatment still required?
The cladding is austenitic stainless steel, and post-weld heat treatment is generally not applied.
