Clamps. I. pipes in shafts and other locations shall be supported by M.S. clamps of design approved by the Independent Engineer. Pipe in wall chases shall be anchored by iron hooks. Pipes at ceiling level shall be supported on structural clamps fabricated from M.S. structural as described in section II. Pipes in typical shafts shall be supported on slotted angles/ channels as specified elsewhere.
Clamps a. M.S. clamps shall be of standard design and fabricated from M.S. flat 40x3mm thick. They shall be painted with two coats of black bitumen paint before fixing.
Clamps. CPVC pipes in shafts and other locations shall be supported by MS clamps of design approved by the Engineer. Pipes at ceiling level shall be supported on structural clamps teardrop shape fabricated on MS structural brackets as described as per drawings. Pipes in typical shafts shall be supported on square rod/channels as specified elsewhere.
Clamps. Internal clamps must be used to keep the pipes in position during the welding. The root opening must be between 1,5 and 3,0 mm and the pipes may not deviate more than 1,5 mm from the concentric. Clamps may be removed only after 50 % of the root weld has been completed in equal sections around the perimeter of the pipes.
