Specification of pipe wall thickness along pipeline axis (Input Table)

Data description/conditions:

Identifier: (toggleable)

Identification name of data reference point

Required

T-NOM1:

Nominal pipe wall thickness just before and at data reference point

> 0.

COR-AL1:

Corrosion allowance just before and at data reference point

≥ 0. and < T-NOM1 / Undefined

(If Undefined no allowance is taken into account)

RTOL1:

Manufacturing tolerance percentage for pipe wall thickness T-NOM1

≥ 0. and < 100. / Undefined

(The wall thickness is reduced with the tolerance percentage if specified)

ATOL1:

Absolute manufacturing tolerance for pipe wall thickness T-NOM1

≥ 0. and < T-NOM1 / Undefined

(The wall thickness is reduced with the value if specified. Either RTOL or ATOL may be specified, not both.)

T-NOM2:

Nominal pipe wall thickness just after data reference point

> 0. / Undefined

(If Undefined it is assumed that T-NOM2 = TNOM1)

COR-AL2:

Corrosion allowance just after data reference point

≥ 0. and < T-NOM1 / Undefined

(If Undefined it is assumed that COR-AL2 = COR-AL1)

RTOL2:

Manufacturing tolerance percentage for pipe wall thickness T-NOM2

≥ 0. and < 100. / Undefined

(If Undefined it is assumed that RTOL2 = RTOL1)

ATOL2:

Absolute manufacturing tolerance for pipe wall thickness T-NOM2

≥ 0. and < T-NOM2 / Undefined

(If Undefined it is assumed that ATOL2 = ATOL1)
