Steel mass, and the inside and outside areas for lining and coating, of pipe, mitred bends, tees and reducers. Pick a standard pipe size or enter your own.
How it’s worked out. Steel volume is taken at the mean diameter, at 7,850 kg/m³. For a standard pipe the mass is scaled to the standard’s published mass per metre; SABS 719 publishes masses 5% above theoretical. A mitred bend’s centre line is 2·(n − 1)·R·tan(α/2) for n segments with half segments at the ends. A tee is the run less the hole for the branch bore, plus the branch cut to its saddle. A reducer is a concentric cone.
Sources. Pipe sizes and masses are from the MPS technical manual: SABS 62 medium and heavy, SABS 719 and ASTM A106 Grade B. Flanges, welds, linings and coatings are not included in the mass.
