The daily maintenance of the integral finned tube

The daily maintenance of the integral finned tube
A suitable maintenance method will have a multiplier effect on the later use of the finned tube. Carry out regular maintenance to reduce the cost and time of fin tube replacement.

1. Regularly check whether the integral finned tube is perfect, whether there are deposits, coking, scales, etc., and clean it immediately. At the same time, it is necessary to check whether the adhesion of each fin tube and the rubber gasket is tight and whether the rubber gasket itself is intact, so as to avoid leakage caused by degumming and damage to the rubber gasket.
2. The compression nut and the upper and lower guide rods of the plate heat exchanger should be frequently lubricated with lubricating grease.
3. Special personnel should be responsible for the adjustment of each instrument, and strictly implement the operating procedures for operation and maintenance.
4. When you need to replace the rubber gasket or repair the degummed part, you need to remove the fin tube, put it on the table, remove the old gasket, or use the glue traces in the groove of the integral fin tube at the degumming place. Wipe with sandpaper, then use carbon tetrachloride or trichloroethylene to wipe off the oil stains in the groove, and then wipe the back of the new rubber gasket with fine sandpaper, and also use carbon tetrachloride or trichloroethylene solvent Wipe off the oil stains. Then apply a thin layer of glue on both the groove and the back of the rubber gasket, and let it dry a little, so that it does not stick to your fingers, but is still sticky. The rubber gasket is inserted into the groove, flattened around it, and a layer of talcum powder is applied. Then install the finned tube on the equipment frame and gently clamp it. According to the requirements of the glue manual, it can be put into production and used every other time.
5. Each time the integral fin tube is re-tightened, pay attention to the position of the scale during the last pressing, and do not over-press the rubber gasket, which may reduce the service life of the gasket.
6. When replacing the fin tube rubber gasket, the section must be updated to avoid uneven gaps between the fins and affect the heat transfer effect.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...

South Korea’s Hot Rolled Steel Plate Production Will Decline this Year

South Korea’s Hot Rolled Steel Plate Production Will Decline this Year It is predicted that Korean domestic production of  hot rolled steel plate  will decline this year due to weak market demand. In the first half of the year, Korean domestic production of hot rolled steel plate was 6.048 million tons, a decrease of 4.8% year-on-year. The main reason for the reduction in production is the large-scale maintenance of related equipment, especially in September and October. Another reason is the recent weakening of demand in the domestic market in Korea. In the second half of this year, besides the small rebound in market demand in the construction industry, the consumption prospects of other downstream steel industries are bleak. However, considering the intensification of trade tensions between Japan and South Korea, South Korea may cut import of hot rolled steel plate, cold rolled steel sheets and pipes from Japan. Therefore, Korean hot rolled steel plate producers ...
