Incoloy 825 0.125 in to 0.625 in Capillary tubing Introductions:

◆Tube Body Load: Yield & Tensile Min‐imums calculated on Specified Wall.

◆Hydrostatic Test Pressure: All completed coiled tubing strings shall be hydrostat‐ic pressure tested prior to shipping. The hydrostatic test pressure shall be lesser of 90% of the theoretical burst yield strength or 17,500 psi or 120700 kpa (unless spe‐cifically agreed between purchaser and manufacturer).

◆Internal Yield: Internal Pressure to cause yielding using Minimum Yield Strength and Minimum Wall Thickness.

◆Maximum Working Pressure is a func‐tion of tube condition and is determined by the user.

◆Torque Values Calculated Using Minimum Wall Thickness and Minimum Yield Strength.

◆Other size/wall thickness available on request.

◆Above data is for new tubing at speci‐fied minimum strengths.
