Section 27: Diagram for an Unequal 45 Degree Lateral

Required Information

• O.D.I.
• Rise
• Height
• Large diameter
• True height

Formulas and Measurements

• Trisect into equal parts and label Extend outside lines from the large diameter to the smaller diameter and continue those lines till they intersect to form an Apex Swing arcs from the Apex of both large and small fitting O.D.I. points Set dividers from I to 2 on the semi-circle and do a 13 point walkout on the large arc (12 for the actual fitting and 1 for a lap allowance.) Add for bead and cccccrimp allowances if needed.

Procedure

1. Step 2

   Draw a semi-circle at the bottom of the Elevation View, using hatf the O.D.I. of the large diameter fitting. Trisect into equal parts and label

2. Step 3

   Extend outside lines from the large diameter to the smaller diameter and continue those lines till they intersect to form an Apex

3. Step 4

   Swing arcs from the Apex of both large and small fitting O.D.I. points

4. Step 5

   Set dividers from I to 2 on the semi-circle and do a 13 point walkout on the large arc (12 for the actual fitting and 1 for a lap allowance.)

5. Step 6

   Add for bead and cccccrimp allowances if needed. Small 00.1. IÆge O.D.I. True Ilfeig arc line arc fine Outside Ene
