technical parameters of large ethylene low temperature full capacity tank
the technical parameters of large ethylene low temperature full capacity tank are as follows:
material selection of main equipment
1. material selection of main container and secondary container of equipment
according to the basic design requirements to be met under the operating conditions of bimetallic full capacity tank, s30408 steel plate is selected for the main container and secondary container of the tank.
2. selection of materials for low temperature pipe fittings of equipment
the low-temperature liquid-phase and gas-phase pipelines of the equipment (from the top plate to the junction point, including the inlet and outlet pipes for nitrogen purging in interlayer space, etc.) are made of low-temperature seamless steel pipes, and the material is s30408.
3. selection of materials for normal temperature pipes and fittings of equipment
the normal temperature pipes and fittings are made of carbon steel with the grade of 20, and the executive standard is gb / t8163-2018 seamless steel pipes for fluid transmission. the fittings are made of 20, and the executive standard is gb / t12459-2017 steel butt welded seamless pipe fittings.
