विश्लेषण सबसे अधिक आम जीआर 1 टाइटेनियम ट्यूब गर्मी एक्सचेंजर रिसाव समस्याएं

Due to the high price of titanium, the traditional stuffing box type titanium tube heat exchanger in the heat exchanger tube selection of titanium, and GR1 tube plate selection of titanium steel composite plate. Due to titanium and steel with non-weldable properties, resulting in titanium tube heat exchanger manufacturing difficulties, so the stuffing box type heat exchanger tube box usually do not use titanium steel composite plate, but the use of carbon steel or low alloy steel tube box overall lining program, which saves costs and reduces the processing difficulty. In order to reduce manufacturing costs and reduce the processing and manufacturing difficulties, in the traditional stuffing box type titanium tube heat exchanger design program, where not in contact with seawater are not used in the part of the Chin material, so the heat exchanger floating tube plate at the tube plate skirt is usually made of carbon steel, which can be avoided to avoid the welding of titanium and carbon steel, but also to reduce costs. Although the traditional stuffing box type titanium tube heat exchanger structure design program to reduce the cost and manufacturing difficulties, but also with a serious equipment leakage problems.

Another common leakage is caused by the rupture of titanium tubes, and the rupture of titanium tubes is usually because the heat exchanger tube is scratched, bruised and other reasons. Because of the high price of titanium, in order to reduce costs, titanium tube heat exchanger selected by the heat exchanger tube wall thickness is usually thin, generally take 0.5mm or so. In such leakage cases, often found in the heat exchanger tube box there are a large number of large particles of sand and gravel or even shells and so on, analyze the reasons, mainly in practice, containing a large number of debris seawater in the heat exchanger tube flow, very easy to cause scratching or abrasion of titanium tubes, in addition to affecting the effect of heat transfer, the heat exchanger life is also greatly reduced, so that the very thin titanium tubes ruptured prematurely, resulting in leakage. Due to structural reasons and difficult to clean up and other environmental conditions, through the patch welding repair is more difficult, only through the sealing of the leaking tube orifice to solve the leakage problem, seriously affecting the heat exchanger heat transfer effect.
