◆Tube Body Load: Yield & Tensile Minimums calculated on Specified Wall.
◆Hydrostatic Test Pressure: All completed coiled tubing strings shall be hydrostatic 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 specifically 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 function 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 specified minimum strengths.
