Prior to shipment, flanges and fittings are usually coated with a protective coating, which not only reduces the potential for corrosion during transportation but also extends their storage time. In addition, special coatings are sometimes applied to ensure optimum corrosion protection.
Commonly used: rust-preventive oil, varnish, paint, galvanized, PE, FBE, epoxy zinc-rich;
Our company can provide the following packing methods for your choice:
● Containerized direct shipments;
