Welding Defects With Stainless Tube
Weld cracking tubes within two-phase corrosion
Highlight the main advantages of duplex stainless-steel is resistant against stress corrosion cracking, the key reason is:as a result of presence of two-phase microstructure, stress corrosion cracking when passing over the phase boundary frequently blocked, expand difficulties; yield high strength duplex stainless, exactly the same applied pressure Under slip deformation hardly occurs, the crack is hard in order to create; ferrite phase to austenite could be the anode to the austenite phase may play a cathodic protection. Even in a multi-sulfuric acid and high temperature water, duplex stainless also has a strong resistance to stress corrosion cracking capacity.
Thus each one of these varieties of machines making use of their devices and piping may cause a hearth hazard or even properly maintained, or if there's an automation failure, fatigue of cloth, or vibration failure. A fire inside the engine room, unless restricted within the beginning often fades of control, causing many times the loss of the ship and life. Thus it is imperative that the machineries and the fire detection and firefighting systems are maintained in efficient condition.
