Joint Design
A customary joint preparation is commonly called an "API"
fitup. While this is not actually an API 1104 requirement,
the figures shown in the specification are drawn to have a
60 degree included angle with a 1/16" (1.6 mm) land and
1/16" (1.6 mm) gap.
As an alternative, for thicker wall pipe (>3/4", >20 mm), a
compound bevel can be used. The amount of material
required to fill a compound bevel joint is less than a 60
degree included angle preparation, so productivity may be
increased.
Pipe Grades
The primary pipe grades are classified in accordance with
the API 5L:2000 specification. This specification establishes
requirements for two product specification levels – PSL 1
and PSL 2. PSL 1 includes mandatory requirements for
chemistry, ductility, minimum yield strength and minimum
tensile strength. PSL 2 adds mandatory requirements for
maximum yield strength, maximum tensile strength and
Charpy impacts.
