Inconel Alloy 693 (UNS N06693) Ferrule or Tube Inserts.
Aditya Steel Engineering co. are glad to Introduce the heat exchanger and boiler heat process Inconel alloy 693 Ferrules (Tube Insert sleeve). Inconel Alloy 693 (UNS N06693) material grade is a new alloy which offers resistance to high temperature corrosion mechanisms not previously available from a nickel-based alloy. The material allows us to produce Ferrules or tube insert sleeve from 0.39”OD (10mm) to 2″ OD (50mm) with a wall thickness of up to 0.196 (5mm). Heat exchanger and Boiler Heat Process tube Insert ferrules are Tube inserts Fabricate to either be sacrificial to the effects of inlet-end erosion, and impingement to induce a fluid to fall on corrosion the ID of a tube in a falling film exchanger or to transfer extremely high heat past the tube sheet to the exchanger and boiler tubes.
Aditya Steel Engg. Co. are professionally Managed engineering company and one of the sole manufacturer and exporters of Inconel Alloy 693 (UNS N06693) Ferrule (tube insert sleeve) CU-NI 90/10 Ferrules and Tube Inserts with seamless tubes or Seam welded flare and one stop pin, plus two anchor pins wrapped insert ferrules, Seam welded and integral flare, Seam welded with welded flare ferrules and tube insert in Thane, Mumbai, India.

Inconel Alloy 693 Material ( FERRULES OR TUBE INSERTS)
INCONEl Alloy 693 (UNS N06693) material Ferrule or Tube Inserts offers the best resistance to metal dusting in chemical and petrochemical processing environments of any conventional alloy currently manufactured.
INCONEL alloy 693 (UNS N06693) offers excellent resistance to corrosive attack at elevated temperatures in a variety of media. The alloy offers excellent resistance to oxidation in air at temperatures up to 1200°C (2192°F).
The alloy also resists oxidation. Alloy 693 demonstrated excellent resistance to carburization when
exposed in a medium containing hydrogen, methane, and carbon dioxide at 1000°C (1832°F).
INCONEL alloy 693 (UNS N06693) is a candidate for service in hightemperature waste and biomass incinerators at temperatures above 700°C (1292°F), where fuel ash corrosion, chloridation and sulfidation can cause rapid failure of traditional materials. Alloy 693 (UNS N06693)may be used to protect super heater walls in low NOx plants. The material can be used either solid or as a weld overlay.
Alloy 693 may be used as an upgrade for alloy 601 and alloy 602CA in heating burner nozzles, which can suffer metal dusting due to new low sulfur regulations for heating oil.

Heat Treatment
INCONEL alloy 693 is a solid-solution, single-phase alloy and as such is supplied in the annealed condition. Annealing of alloy 693 can be accomplished by heating to 1850° to 1950°F (1010° to 1066°C), and holding for a time commensurate with section thickness, followed by rapid cooling in air or water quenching (recommended quenching method dependent upon section thickness – consult the manufacturer).
The purpose of the Tube Ferrule Inserts
1) Protect inlet-end erosion & corrosion
2) Act as a protective layer
3) Reduce the medium impact
4) Transfer extremely high heat past the tube sheet to the exchanger tubes.
Common problems at Shell & Tube Type Heat Exchangers
1. Tube-end erosion/corrosion
2. Stress Corrosion Cracking
3. Crevice corrosion
4. Localized pitting
5. Ammonia grooving
6. Improper tube expansion
7. Weakened tube-to-tube sheet joints
