Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Duplex S31803 Tube to Female Pipes, which is normally supplied in the solution – annealed condition. Forging of these Duplex S31803 Tube Fittings should be started immediately the stock is removed from the reheat furnace and 25 % / 40 % reductions help to retain as much internal heat as possible. For optimum corrosion resistance, forged parts of Duplex S32205 Tube Fittings should be subsequently annealed. Treatment of these Duplex S31803 Compression Fittings is carried out at 2050 Degree F (1120 Degree C) followed by water quench or rapid air cool.

Duplex S31803 Tube to Female Pipes

The treatment in Duplex S32205 Compression Fittings is performed after hot working to ensure optimum corrosion resistance and between cold – working operations. These Duplex S31803 Female Connector Fittings is considered moderate till difficult to machine, but can be machined using conventional methods. Duplex S32205 Female Connector Fittings has a high work hardening rate, and efficient machining requires rigid and overpowered machines, sharp tools, preferably carbide – tipped, and heavy, constant feeds.

In chemical processing applications, these Duplex S31803 Ferrule Fittings has exceptional resistance to sulphuric, hydrochloric, formic, acetic, and phosphoric acids. Duplex S32205 Ferrule Fittings performs well in environments containing acid chlorides, solvents and acetic anhydride. These Duplex S31803 Double Ferrule Fittings is one of the few grades that withstand wet chlorine gas, hypochlorite and chlorine dioxide solutions.
