Import Flange Protector Band — Buy in wholesale FOB from Supplier in China

The Flange Protector Band from Wenzhou TST Plastic Co., Ltd. is a composite sealing and shielding system designed for industrial flanges exposed to corrosive environments. It consists of a 316 stainless steel outer band, a 316 stainless steel worm gear clamp, a 316 stainless steel injection fitting, and a neoprene foam liner rated for a maximum operating temperature of 180°F. The band is engineered to fully enclose flange faces, stud bolts, and gaskets to prevent ingress of moisture, saltwater, acid rain, and chemical residues.

The neoprene liner provides a compressible seal that conforms to irregular flange surfaces, while the 316 stainless steel components offer superior resistance to chloride-induced corrosion compared to 304 grade. This construction aligns with standard practices in offshore oil and gas, chemical processing, and marine applications where cathodic protection systems are active. The injection fitting allows for periodic re-lubrication with stainless grease, maintaining long-term sealing integrity without disassembly.

Buyers in pipeline construction, refinery maintenance, and water treatment sectors use these bands to extend flange service life and reduce unplanned shutdowns. The product is available in standard flange sizes up to 48 inches, with no minimum order requirement stated. Packaging is typically bulk-packed in cartons, and trade terms such as FOB or CIF can be confirmed directly with the supplier. Lead times are not specified and must be verified prior to order placement.
