Description:
Steam Header is a type of pressure vessel, pressure vessel is a closed container
Designed to hold gases or liquids at a pressure substantially different from the
Ambient pressure. They are extensively applicated at petrochemical industry,
Energy industry, scientific research and other industry.
Pressure Vessel oversize:
Grades of pressure vessels undertaken by JIEMA:
D1 (Type I pressure vessels): 0.1Mpa ≤ P ≤ 1.0Mpa
D2 (Type II low and medium pressure vessels): 1.0Mpa ≤ P ≤ 1.6 Mpa
Pressure vessel products manufactured by JIEMA:
Volume heat exchanger
Shell-and-Tube Heat Exchanger
Steam Header
Gas storage tank and etc.
For a sphere, the mass of a pressure vessel is
Where:
Is mass,
Is the pressure difference from ambient (the gauge pressure),
Is volume,
Is the density of the pressure vessel material,
Is the maximum working stress that material can tolerate.
Other shapes besides a sphere have constants larger than 3/2 (infinite
Cylinders take 2), although some tanks, such as non-spherical wound
Composite tanks can approach this.
Cylindrical vessel with hemispherical ends.
This is sometimes called a bulle for its shape, although in geometric terms
It is a capsule.
