Preinsulated curved pipe

Delivered in lengths of 12 and 16 m. Curved pipes are supplied with embedded copper wires for surveillance. When ordering please state length, bending angle, and bending directions. Direction: When ordering please state the direction in which the pipes must be bent:   ↑  up   ↓  down   ←  left   →  right The direction is defined on the assumption that the tinned wire is to the right and the bare copper wire to the left. Geometry: vp   = Bending angle, degrees Rp  = Design radius, m L1  = Length of straight pipe ends, m Tol  = Tolerance of angle, degrees The tolerance is calculated as a 1/3 of the elastic angle of the steel pipe. Manufactured curved pipes are delivered in angles in whole 1° intervals. However, for dimensions larger than DN500 with 1 decimal place. In addition the max. bending angle, v°p must be determined in relation to the stress level under which it is being installed, see Design.
