The acid‑resistant, corrosion‑proof carbon bricks produced by Qinyang Xinghui New Materials are crafted from premium graphite carbon materials and enhanced with highly acid‑resistant organic composites. Through high‑pressure molding, vacuum impregnation, and high‑temperature heat treatment, these bricks achieve exceptional acid resistance and thermal stability, making them an ideal lining material for chemical equipment such as phosphoric acid reaction vessels and storage tanks.

● Process flow

● Applications include linings for phosphoric acid, hydrochloric acid, and hydrofluoric acid storage tanks, reaction vessels, phosphoric acid storage tanks, phosphoric acid scrubber tower linings, and chimney linings.

       We offer proven solutions to combat corrosion caused by acids, alkalis, chemicals, and highly corrosive environments.

We provide acid-resistant solutions for chemical storage and reaction tanks, drainage pipes, battery rooms, floors, ETP systems, galvanized tanks, pickling areas, desalination units, towers, cabinets, excavators, drying towers, neutralization pits, and more.

We have provided services to numerous clients, protecting their equipment and structures from ongoing chemical attack and extending the service life of tanks, vessels, reactors, and other structures—thereby saving substantial capital expenditures and minimizing production downtime.
