Super duplex tube fittings

Super duplex tube fittings

Super duplex tube fittings are composed of 19-28% chromium and up to 5% molybdenum and lower nickel contents. Super duplex stainless steel compression fittings are durable and provide strong connections. They work efficient up to a limited range of temperature up to 300°C. Super Duplex material instrumentation tube fittings have limited cryogenic temperature up-50°C. Designed with strong mechanical properties Super Duplex compression fittings are capable of maintaining their strength in harsh environmental conditions also.

Super Duplex instrumentation fittings are widely used in the desalination plants, heat exchangers, pipe system, oil, gas, chemical processing industries, also the rotors, shaft and hydraulic lines also utilize these tube fittings.

Find tips and trick to stop leakage from genuine super duplex compression fittings suppliers

There are several measures that needs to be considered in order to stop Super Duplex grade hydraulic fittings from leaking:

  • Properly utilizing of reliable connectors such as BSPP, SAE four-bolt, UN-O-ring and ORFS as these involves an elastomeric seal which provides excellent seal reliability.
  • Do not use tapered- thread connectors such as BSPT and NPT which are considered as least reliable type of connector because this thread provides path for spiral leakage.
  • Using a smaller number of connectors and utilizing cartridge valves, stack valves and manifold at some joints.
  • Fittings must not be over-tightened which can distort ferrules and seals leading to cracking of flared ends and metal fatigue.
  • Tube fittings must be compatible.
  • Torque them correctly
  • Maintaining the machine with cool temperature.

Be alert and careful towards short-circuit vibration, if short-circuit vibration observed quickly shut down the system.

Parker/ Swagelok equivalent super duplex male connector for maximum working pressure at the best price in Dubai

The prime function of a Super Duplex male connector is to prove secure connection between the two tubes. The method involves the male connector is fitted into the female end of tube fitting and then tightened them to provide a secure seal by connecting both the tubes and prevent leakage. Have excellent workability and weldability properties.

Super duplex instrumentation fittings and SDSS high pressure compression fittings for failure-free operation

Super Duplex compression fittings are highly resistance to crevice and pitting corrosion hence widely used in the seawater and marine applications. Due to their strong oxidation property, they prevent the material from rusting. SDSS high pressure compression fittings are composed of high tensile strength and resistance against many stress conditions. Exhibits excellent hardness provide easy installation and maintenance.

The difference between super duplex steel flare compression, hydraulic, and pneumatic fittings is basically depended of the industrial applications and their respective properties.

  • Super Duplex Flare fittings- used for high pressure applications, commonly used in hydraulic systems which requires a flaring tool for installing it.
  • Super Duplex Compression fittings- have low pressure applications widely used in the instrumental systems which requires a compression tool to install it.
  • SDSS Hydraulic fittings- utilized in the hydraulic systems and comes different types which includes PTFE hose, crimp, field attachable hose, etc.
  • Super Duplex Pneumatic fittings- are used in the pneumatic systems and comes in several types which includes flare fittings, face seal fittings, swivel fittings, weld fittings, etc.
