1. Reference document
2. Nomenclature
3. Axial movement displacement per convolution
4. Number of cycles for each condition of stress cycle
5. Calculated force and moment --- AT ambient temperature
6. Study of bellows stability --- At design temperature
7. Pipe temperature
8. Materual steel to extend ability
9. Table of saturated vapor
10. Table of thermal expansion
11. Conversion table of temperature
 
1. The diameter of pipe If pipe is nominal diameter or rectangular type inside size, we need
measurements of width and length.
2. The standard, the thickness,and material of the pipe You should present the standard of the pipe, material (SPP, SPPS38, SPW,
and so on), the number of schedule. If the pipes aren't standardized goods
you should present the external diameter of the pipes(or the inside diameter)
the thickness, the material, If it is welded type, you should present The
appearance of bevel,(Single bevel or dual bevel, ETC,)
3. How to connect If it is connection of FLANGE, we need that standard or measuremments,
Material, etc. Especially, if it is 650A and over, you should pay attention to
standard (API, MSS, LADISH, TAYLOR)
4. Fluid Condition of Fluid
5. Pressure of Design Application of piping condition
6. Temperature of Design Application of piping condition
7. Movement

Application of piping location condition

8. The material of BELLOWS

According to fluid, temperature, pressure, we will choose best one. But if
you specify specially, you should present the temperature of the fluid and
the specificity of the material.
(We will reexamine.)

9. Inspection Specification of owner
10. The Calculation Date We usually calculate by our standards of design. But if it is needed to specify
specially, you should present the calculating formula and the standard cycle
life frequency.
11. Others If you use it in special point or can't set up a fixed point, you should take
counsel with us in advance.
