Owing to its versatile physical structure coupled with its efficient chemical diversity, the duplex S31803 flanges are known to exhibit excellent strength and toughness. This tough nature of the flanges is responsible for enabling them to strengthen the system and also defend themselves against any kind of mechanical strain. This same stability is seen when they are faced with corrosive liquids and gases including several acids. This stability can be attributed to the corrosion resistance they expertly manifest against a broad range of corrosive agents, protecting themselves against pitted, crevice, and stress corrosion, without letting it affect its performance in any manner. This property has enabled them to be used in applications involving exposure to such liquids, which only broadens the spectrum of its usage.

These diverse traits attributed to the duplex S31803 flanges are widely used in several applications and among them are acid manufacturing units, chemical industry, heat exchangers, etc.
Regular tests and periodic inspections are strictly conducted in our factories to check if the products and the operating conditions are as per the regulations.
