Specification of cross-sections to be calculated according to the Belgian Law for natural gas pipelines (Input Table)

Data description/conditions:

Start Identifier 1 3: (toggleable)

Identification name of first element where stress calculations have to be done

Required

End Identifier 2 3: (toggleable)

Identification name of last element where stress calculations have to be done

Required / Undefined

(If EELEM = Undefined, it is assumed that EELEM = SELEM)

TOPLOAD:

Indicator whether TOPLOAD has to be taken into account in stress calculations

Prescribed names:
No: TOPLOAD will not be added to top soil load
Yes: TOPLOAD will be added to top soil load

CTYPE:

Construction type

Prescribed names:
A, B, C, D or New

(- For existing pipelines (dating from before 24-1-1991) the allowable hoop stress is dependent on the construction type A, B, C or D. See Belgian law, Royal Decision dated 11 march 1966.
- For new pipelines laid after 24-01-1991 (NEW) a modification of the law is applicable meaning that the allowable hoop stress is dependent on the yield stress of the pipe material.
- The program determines the allowable hoop stress starting from the specified CTYPE and checks the calculated hoop stress(es).)

 

1Toggle data in subsequent rows do not have to contain increasing values.

2The parameters specified at the 'Start Identifier' are applicable up to the 'End Identifier'. When 'End Identifier' is left empty it is assumed that EELEM = SELEM

3Elements outside any specified region will not be calculated.
