Selection of equipment main container, secondary container, and thermal corner protection materials
According to the basic design requirements to be met by the operating conditions of the bimetallic full containment tank, the main container, the secondary container and the hot corner protection material of the storage tank are all made of low-temperature resistant austenitic stainless steel S30408. The "belt" standard requires that it be supplied in the state of solution heat treatment, and the surface processing type is 1D. The steel plate must not have delamination, and the surface must not have defects such as cracks, bubbles, inclusions, and stuttering.
Equipment low temperature pipeline material selection
Equipment for low-temperature liquid phase and gas phase pipes (from the top of the suspended ceiling to within the junction, including thermal angle protection pressure balance pipe and thermal angle protection interlayer space nitrogen purge inlet and outlet pipes, etc.), the materials are all low-temperature seamless steel pipes, and the material is S30408 , The executive standard is GB/T14976-2012 "Stainless steel seamless steel pipe for fluid transportation"
equipment room temperature pipe fitting material selection
The normal temperature pipeline uses carbon steel material, the material is 20#, the implementation standard is GB/T8163-2008 ``Seamless steel pipe for conveying fluids'', and the pipe fittings use 20# material, the implementation standard is GB/T12459-2005 ``Steel butt welding seamless Pipe fittings.
