Force container

1. Walking on the edge of the law
therefore, the risk of your domestic trading is greater
there is no free market
you can buy it, but it's not easy to sell.

2. V= π/ 24*Di^3+ π/ 4 * Di ^ 2 * h
where Di is the inner diameter of standard elliptical head and
H is the height of straight edge
^ 3 is cubic
see gb25198-2010 appendix a

use Excel to make the formula, input the inner diameter and straight edge height to automatically get the volume.

3.

Calculated pressure: the pressure used to determine the thickness of the element at the corresponding design temperature, including the static pressure of the liquid column and other additional loads

Different objects: the design pressure is for each chamber of the vessel, while the calculation pressure is for each pressure element of the vessel

The design pressure of each chamber is determined according to its working pressure, opening pressure of safety valve or bursting pressure of bursting disc. The calculated pressure is determined according to the design pressure of each chamber of the vessel plus the static pressure of the liquid column

The design pressure is the basis for the selection of materials, classification, manufacturing and inspection requirements, determination of test pressure, etc; Calculated pressure is to determine the thickness of each pressure element of the vessel to meet the requirements of strength, stability and stiffness

extended data:

internal and external inspection of pressure vessel, which can only be carried out after shutdown and cleaning of the vessel. The main contents of the inspection include not only all the contents of external inspection, but also the corrosion and wear of internal and external surfaces; Use naked eye and magnifying glass to inspect all welds, head transition zone and other stress concentration parts for cracks

When necessary, the internal quality of welds shall be inspected by ultrasonic or radiographic testing; Measure the wall thickness. If the measured wall thickness is less than the minimum wall thickness of the vessel, the strength should be checked again, and the use or repair measures should be put forward; If necessary, metallographic examination should be carried out for vessels that may cause changes in metallographic structure of metal materials

4. There is no solution to this question. Because the pressure that the vessel wall can bear is related to the material, thickness and diameter of the vessel wall. The allowable stress should be determined according to the type of steel plate, and the wall thickness should be calculated according to the formula according to the diameter and pressure of the vessel. Please refer to books on pressure vessels&# 92; r\ N further: & 92; r\ The design, manufacture, installation and operation of pressure vessels have strict rules and regulations, which are managed by the Labor Department of the government. The relevant units need to have certain qualifications and be approved before they can carry out the design, manufacture and installation. Operators must also be trained&# 92; r\ N 150 atmospheric pressure is already a high-pressure vessel, so you can't do it casually.

5. Divided into several cases to determine, hg21580-2011 has a detailed description, their next standard to see it, there is a network library.

6. Secondary stress and peak stress can be calculated and checked by shakedown theory. For details, please refer to JB4732 steel pressure vessel - Analysis and design standard.

7. Firstly, the volume of the straight section of the container is calculated according to the inner diameter and the height of the straight section
then find out the volume of the lower head with the corresponding diameter according to the manual of the head
the whole container is the volume of the straight section plus 2 times of the head container

8. F floating= ρ Liquid GV discharge
