Ravi - just an additional point - in the case that the pipe continues parallel to other lines in a change of direction piperack- the pipe thermal expansion at those points will affect the pipe spacing - (normal pipe to flange) + clearance + insulation + expansion. Most companies will allow "cold spring" (1/2 of the total thermal expansion) to assist in final pipe spacing in turns of direction of piperacks. Happy Piping

Re: [PipingDesign] Sloped headers

Bruce- Design temp. is 190 degree C and operating temp is 160 degree C. Line is anchored in the middle of the rack at one of the anchor beams, allowing it to grow both sides. As usual alternately guided every 12 m.

Ravi - Just a quick question - there is about 8" expansion in the 120mt. length at 120C. How is this being accomodated : fixed 1/2 way with displacement at the ends,expansion loop, fixed at a piece of equipment with all expansion one way? Also is the 120C operating or design temp?
