Pressure terminology
| Welding terminology T = Time P = Pressure B = Bead size Pipe terminology ND = Nominal Diameter ID = Internal Diameter OD = Outside Diameter T = Thickness NP= Nominal Pressure SDR = Standard Dimensional Ratio Relation between the Outside diameter and Thickness of the wall | PSI= Pound square inches MPa= Mega Pascal 1 MPa= 10 Bar = 145 PSI = 1 N/mm² = 100 N/cm² 1 In² = 6.4516 cm² 1 cm² = 100 mm² = 0.155 In² 1 mm²= 0.01 cm² = 0.00155 In² = 0.00001076 Ft² 1 mm = 0.1 cm = 0.03937 In = 0.7854 mm² = 0.001217 In² DRAG = Drag pressure TEPA = Total Effective Piston Area |
