B. DIMENSIONS

Dimensions Specification Tolerances
Standard Pipe Length (L) Standard Length 12 m. random length r factory joined lengths supplied shall not exceed 10% of the order (BS 5480). + 25 mm
Out of Squareness End shall be square to both axis of the pipe plane. (BS 5480). Not to exceed 2 + 0.005 D (mm) where D is the nominal diameter of the pipe or 10mm, whichever is smaller.
Straightness Pipes shall be straight (BS 5480). Not to exceed 0.3% of the effective length of the pipe or 15mm, whichever is smaller.
Thickness As per ADVANCED PIPES & CAST CO. thickness Single point 87.5% of minimum average.
Roundness Deviation Impact Resistance Pipes shall be round. As per BS 5480 + 1% When tested in accordance with appendix J, H 50 shall be at least 0.3m.

C. SPECIFIC TANGENTIAL INITIAL STIFFNESS (STIS)

The minimum specific tangential initial stiffness is 2500; 5000 or 10000, and determined as per as TMMD 2412 or BS 5480.

D. MECHANICAL PROPERTIES

All pipes will exhibit the following properties:

Property Design Value
Linear coefficient of thermal expansion (mm/mm/oC) 25 to 30X10
Poisson's Ratio 0.17 to 0.3
