Carbon Steel 45° Long-Radius BW Elbow
Changes the pipe direction by 45 degrees with long-radius geometry. Match the fitting outside diameter, wall thickness and weld preparation to the pipe.
Wall series: Sch 40 / Sch 80. Specify the carbon-steel grade and required material standard in the order. Material grade and pressure-temperature suitability require confirmation for the requested service.
Reading the Dimensions
B is the centre-to-end dimension for the 45° LR elbow. For example, the reference table gives NPS 2: OD 60.3 mm and B 35 mm. Use the LR column for this fitting.
Dimensions quoted here are nominal reference values in millimetres. Confirm the actual dimensional standard, tolerances and end preparation for the supplied fitting.

Carbon Steel 90° Long-Radius BW Elbow
Changes the pipe direction by 90 degrees. Specify LR explicitly; an SR elbow has different installation dimensions.
Wall series: Sch 40 / Sch 80. Specify the carbon-steel grade and required material standard in the order. Material grade and pressure-temperature suitability require confirmation for the requested service.
Reading the Dimensions
A is the centre-to-end dimension for the 90° LR elbow. For example, the reference table gives NPS 2: OD 60.3 mm and A 76 mm. Confirm the installation clearance.
Dimensions quoted here are nominal reference values in millimetres. Confirm the actual dimensional standard, tolerances and end preparation for the supplied fitting.

Carbon Steel Equal BW Tee
Creates a branch with all three ends of the same nominal size. A reduced branch requires a reducing tee with its own specified dimensions.
Wall series: Sch 40 / Sch 80. Specify the carbon-steel grade and required material standard in the order. Material grade and pressure-temperature suitability require confirmation for the requested service.
Reading the Dimensions
C is the run centre-to-end dimension and M is the branch centre-to-end dimension. For NPS 2, the reference table gives OD 60.3 mm and C = M = 64 mm. The equal-tee table does not cover reducing tees or crosses.
Dimensions quoted here are nominal reference values in millimetres. Confirm the actual dimensional standard, tolerances and end preparation for the supplied fitting.

Carbon Steel BW End Cap
Closes a pipe end by butt welding. Select the weld-end diameter and wall thickness to match the line specification.
Wall series: Sch 40 / Sch 80. Specify the carbon-steel grade and required material standard in the order. Material grade and pressure-temperature suitability require confirmation for the requested service.
Reading the Dimensions
E is the cap length. The table uses a wall-thickness threshold, t limit, to choose between two E columns; this threshold is not the Schedule wall thickness. For NPS 2, OD is 60.3 mm and t limit is 5.59 mm: E is 38 mm when specified t ≤ 5.59 mm, or 44 mm when t is greater. Length for NPS 26 and larger requires agreement when ordering.
Dimensions quoted here are nominal reference values in millimetres. Confirm the actual dimensional standard, tolerances and end preparation for the supplied fitting.

Carbon Steel Eccentric BW Reducer
Connects different nominal pipe sizes with offset end centrelines. Specify the required installation orientation to match the piping design.
Wall series: Sch 40 / Sch 80. Specify the carbon-steel grade and required material standard in the order. Material grade and pressure-temperature suitability require confirmation for the requested service.
Reading the Dimensions
OD L and OD S are the large- and small-end outside diameters; H is overall length. For 2 × 1 1/2 inches, the reference gives OD L 60.3 mm, OD S 48.3 mm and H 76 mm. Specify wall thickness at both weld ends.
Dimensions quoted here are nominal reference values in millimetres. Confirm the actual dimensional standard, tolerances and end preparation for the supplied fitting.

Carbon Steel Concentric BW Reducer
Connects different nominal pipe sizes on a shared centreline. State both end sizes and the required wall series.
Wall series: Sch 40 / Sch 80. Specify the carbon-steel grade and required material standard in the order. Material grade and pressure-temperature suitability require confirmation for the requested service.
Reading the Dimensions
OD L and OD S are the large- and small-end outside diameters; H is overall length. For 2 × 1 1/2 inches, the reference gives OD L 60.3 mm, OD S 48.3 mm and H 76 mm. The reducer tables show documented size combinations, rather than an inventory list.
Dimensions quoted here are nominal reference values in millimetres. Confirm the actual dimensional standard, tolerances and end preparation for the supplied fitting.

Carbon Steel BW Technical Reference
The ALFACOM reference provides nominal geometrical dimensions and schematic drawings. Schedule is a wall-thickness series, not a pressure rating. Operating suitability depends on the material, size, wall, temperature and applicable piping specification.
