ASME SA105N Carbon Steel Self Reinforced Nozzle Pressure Vessels Part

ASME SA105N Carbon Steel Self Reinforced Nozzle Pressure Vessels Part

ASTM A105 is a carbon steel material specification that is primarily used for forged components, such as flanges, fittings, and valves, in piping systems. However, ASTM A105 is specifically intended for forged products and is not typically supplied in sheet form. This is because the mechanical properties and chemical composition of ASTM A105 are tailored to forging applications rather than rolling or forming into sheets.

Chemical Composition:

Mechanical Properties:

When referring to self-reinforced nozzles, it is generally assumed that the reinforcement to withstand the loads that affect the nozzle will be a constitutive part of the nozzle. This means that self-reinforced nozzles do not need auxiliary elements (like built up nozzles) to withstand design conditions and external loads.On a practical level, self-reinforced nozzles are those that do not have any additional kind of reinforcement (pad) attached, and all the welds between its own components and between the nozzle and the vessel are full penetration type. Because of that, these nozzles could be named integrally reinforced as well.There are different configurations of self-reinforced nozzles. The most commonly used are the mentioned as follows: Long Welding Neck (LWN) or straight hub, variable hub thickness, and nozzles manufactured using a standardized thickness pipe.
