Tube internals were protected by inserting specially designed plastic caps on Inlet/Outlet and Return side of Water Box. This protected the condenser tube sheet. The entire face was hot washed to remove any lubricants and other potential contaminants before abrasive blasted to ensure surface is clean and the correct surface profile is obtained.
Condenser & Chiller Services provides complete shell and tube heat exchanger support Our service group is comprised of individuals who have been in the industry for over 30 years. We have repaired and retubed centrifugal chillers with capacities up to 12,000 tons, and recip condensers as small as 20 tons. Jan 21, 1975 · The invention contemplates a steam-surface condenser construction wherein an assembly of spaced tube sheets, associated tubes and water boxes is axially compliantly supported with respect to the condenser shell, and wherein the said assembly further includes elongate strain-proportioning mechanism extending between the tube sheets and ... Jan 22, 2018 · In this video I described about construction and working principle of shell and tube type condenser which is one kind of surface condenser. Condenser tubes are specifically designed to efficiently condense process fluid off of the outside of the tube. This application is widespread in heat exchangers, from being part of a condenser and evaporator refrigeration cycle in a chiller, to condensing steam in surface condensers, and everything in between.
attempt to repair the condenser before that time. Because re tubing the condenser would have cost 4 times the cost of coating the condenser tubes, the client opted to have Curran International apply coating to the condenser tubes and tube sheet. Also a condenser re tube would have been difficult in the bottom of a ship where space is limited. By expanding the tube inside the tubesheet, swaging ensures that the space between the two components is always forced closed. Hydraulic expansion is the direct application of high internal pressure within a tube or sleeve in order to form a tight joint between the tube and tube sheet or a tight seal between the sleeve and tube. Calculations of Condenser Performance Using PEPSE By Gene L. Minner, PhD SCIENTECH, Inc. And Timothy M. Feigl Ameren Energy Generating Company ABSTRACT This paper presents calculation models of a condenser, common to electric power generation stations. Calculations quantify the condenser’s shell pressure as it depends on characteristics of There are multiple openings for heat exchanger tubes that pass through the blind cover. I tried to determine the thickness based on rules of UG-39 with multiple openings, but the spacing of the tubes rule that out. The tubes are not providing any "staying" to the tube-sheet because they are not attached at opposite end to anything.
