Description
1.Drill pipe:

Drill pipe is in accordance with API SPEC 5D, it can be divided into two groups:
Group 1--Grade E drill pipe
Group 3--All high strength grades of drill pipe .(Grades X-95, G-105, S-135)

aThe minimum elongation in 2 in.(50.8mm) shall be that determined by the following formula:
e=625,000A0.2/U0.9
where e = minimum elongation in 2 in (50.8 mm) in percent rounded to nearest 0.5%.
A = cross-sectional area of the tensile test specimen in square inches, based on specified outside dia- meter, or nominal specimen width, and specified wall thickness rounded to the nearest 0.01 in.2, or 0.75 in.2, whichever is smaller.
U = specified tensile strength, psi.

Note: See Table 5 in API SPEC 5D for minimum elongation ＆#118alues for various size strip tensile specimens and grades. The minimum elongation for either round bar tensile specimen (0.350-in. diameter with 1.4 -in, gauge length and the 0.500-in. diameter with 2.00-in. gauge length) shall be that shown in Table 5 for a cross-sectional area "A"of 0.20 in.2.

Tolerances on Dimensions

The following tolerance apply to the outside diameter of the drill pipe body immediately behind the upset for a distance of approximately 5 in. for sizes 5-1/2 and smaller, and a distance approxi- mately equal to the OD for sizes larger than 5-1/2. Measurements shall be made with calipers or snap gages.

Inside Diameter: d, is governed by the outside diameter and weight tolerances.
Upset Dimensions:Tolerances on upset dimensions are given in Tables 7 and 8 in API SPEC 5D.
Eccentricity:
Outside Diameter: The maximum eccentricity, measured with a saddle gage (see Figure 5) at a di-stance of 5 to 6 in. from the end of the upset, shall not exceed 0.093 in. (total indicator reading).
Inside Diameter: The maximum eccentricity of the bore of the upset with respect to the outside surface of the drill pipe shall not be more than 1/16 in. (1/8 in. total indicator reading).
Ovality: Maximum ovality, measured with a micrometer on outside diameter of upset shall not exceed 0.093 in.
