China 304 stainless steel tube cleaning maintenance way

1. The cold plate is processed by cold rolling, and the surface has no oxide skin, and the quality is good. The hot plate is processed by hot rolling, and the surface has oxide scale, and the thickness of the plate is lower.A part of the home to the air conditioning cleaning also does not pay high attention to, some people immediately wipe the air conditioning shell clean think clean up the past, in fact, there are also many components must be cleaned, if not cleaned up for a long time will cause harm to the body. Because of the uniqueness of the standard natural environment in the work of fan coils, it is stipulated that it is in the application of the whole process in addition to carry out general maintenance, but also need to pay particular attention to the following cleaning and disinfection sterilization work in: in the cleaning of central air conditioning before the need to prepare the required supplies and detergent, it is best to buy special type of air conditioning cleaner or cleaning powder.

2. The filter is generally 3 months to clean up once, its cleaning method should be preferred to vacuum machine suction clean method, the greater advantage of the method is no need to disassemble the filter. For not easy to suck neat soot, it is necessary to remove the filter screen with cold water to fill the pressure cleaning or cleaning, clean up after drying and then install the filter screen structure on. Strainer cleaning work is the most frequent and labor intensive work on the coil fan repair and maintenance work, must give sufficient high priority and effective distribution.

3. Installed water plate generally clean up 2 times a year, if the coil fan is only periodically applied, then clean up once after the application of the operation. Clean up method generally tap water to flush in, waste water by the drainage pipe discharge out. In order to better sterilization and disinfection, to clean up the neatly installed water tray and then use disinfectant solution (such as bleach) to clean again.

4. China 304 stainless steel pipe plate fin type between the adhering soot condition, once a year blowing suction or tap water clean up once; plate fin type have lapped have to use flaccid comb comb good, application of household central air conditioning special type cleaning agent clean, scale cleaning, after removing bacteria to maintain natural ventilation smooth.

5. according to the centrifugal impeller dirty soot condition, once a year to clean up. If it is not cleaned immediately, the air volume of the centrifugal fan will be significantly reduced, energy consumption will be increased, noise will be increased and the overall characteristics of the coil fan will be reduced. Centrifugal impeller has a vortex shell surrounded by, not disassembled out of the elimination of cleaning work is more difficult to do, can choose to use small and medium-sized ultra-powerful vacuum cleaner cleaning method or cold water cleaning.

6. pay attention to the three-way joint or gate valve seepage to repair or remove and replace. If the installed water tray, water pipes, ventilation duct insulation materials have been destroyed to repair or remove and replace. When the coil fan is not applied, the coil should be filled with water to reduce pipeline corrosion. In winter, the fan coil is not used, and there is no heating in the natural environment need to use cold countermeasures, to prevent the fan coil freeze broken. Usually pay attention to check the temperature control open view and relay manipulation is not dexterous, posture is not all normal, there are any problems to deal with immediately.

7. Hot-rolled steel plates are divided into thick plates (thickness greater than 4mm) and thin plates (thickness 0.35~4mm); cold-rolled steel plates only have thin plates (thickness 0.2-4mm).

China 304 stainless steel tube processing and precautions

Cold-rolled coils are made of hot-rolled steel coils, which are pickled to remove oxide scale and then cold rolled. The finished product is hard-rolled coils. The strength and hardness of the hard-rolled coils increase due to cold work hardening caused by continuous cold deformation. , Tough plastic index declines, so the stamping performance will deteriorate, can only be used for simple deformed parts. Cold rolling is processed from hot-rolled sheets at room temperature. Although the rolling process will heat up the steel plate, it is still called cold rolling. Because the hot rolling is cold rolled after continuous cold deformation, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties, and the ones that are not annealed are called rolled hard coils. Rolled hard coils are generally used to make products that do not need to be bent or stretched.China 304 stainless steel pipe cold-drawing deep processing: easy to produce friction heat so the use of pressure-resistant, heat-resistant stainless steel pipe species at the same time forming processing should be removed after the end of the oil attached to the surface.

Stainless steel pipe processing welding: welding should be thoroughly removed before the harmful rust, oil, water, paint, etc., selected for the steel welding rod. Spot welding time distance than carbon steel spot welding spacing is shorter, remove the weld slag should use stainless steel pipe brush. After welding, in order to prevent local corrosion or strength loss, the surface should be abrasive treatment or cleaning.

Cutting and stamping: because of the high strength of stainless steel pipe than the general material, so stamping and shear need higher pressure, and knife and knife clearance is accurate in order not to cut bad and processing hardening, the best use of plasma or laser cutting, when had to use gas cutting or arc cutting, the heat-affected zone for grinding and the necessary heat treatment.

Stainless steel pipe processing bending: book plate can be bent to 180, but in order to reduce the bending surface of the crack with the size of the best radius 2 times the thickness of the plate, thick plate along the direction of calendering to 2 times the plate thickness radius, and calendering perpendicular direction bending to 4 times the plate thickness of the radius is necessary, especially when welding, in order to prevent processing cracking should be surface grinding of the welded area.

In order to prevent scratches and contaminants from adhering during construction, stainless steel construction is carried out in a film state. However, with the extension of time, the residue of the paste liquid in accordance with the use of the film, construction after the removal of the film should be surface washing, and the use of special stainless steel pipe tools, and general steel cleaning common tools, in order not to let the iron chips stick should be cleaned. Should be careful not to have a very strong corrosive magnetic and stone luxury cleaning with drugs to contact the surface of the stainless steel tube, if contact should be washed immediately.

What are the characteristics of China 304 stainless steel tube?

China 304 stainless steel tube characteristics are also a lot of characteristics, in everyday life is also very common, the characteristics of the outstanding is also one of the reasons why we are in the application of a wide range, but its characteristics characteristics or there are a lot of people do not understand, the following we will talk about the characteristics of China 304 stainless steel tube what are they?

1.China 304 stainless steel tube cleanup reliable and no need to worry about red water, white water and other phenomena.

2. China 304 stainless steel pipe because of the relatively light, can easily transport and engineering construction and reduce costs. Thick-walled stainless steel plate capillary because of corrosion resistance and mechanical equipment role is excellent, only must hot-dip galvanized steel pipe thin thickness of about one-third can be. Thus the net weight of China 304 stainless steel pipe is considerably lighter, the cost is also reduced with the transport more lightly, machinery and equipment more convenient.

3. Corrosion resistance is very good: because China 304 stainless steel tube surface will form a very thin protective film, although this protective film is about 3 × 10-6mm, but very tough, even if destroyed, only the surrounding co2, you can immediately recycle and avoid rust corrosion, only need to understand the characteristics of stainless steel plate and precise application of the word, in the tap water pipe or up to 100 ℃ boiling water, etc. Under the standard of less corrosion, basically do not need to worry about rust, but also do not need to worry about the development of common "rust protrusions" in the hot-dip galvanized steel pipe composed of reduced internal diameter or friction resistance to expand the phenomenon, can obtain the flow of water not easy to plug.

4. Distortion: in the construction site, the construction team often apply China 304 stainless steel tube plastic deformation and not according to the engineering construction specification mandatory engineering construction, therefore, must think about China 304 stainless steel tube and pipe docking distortion factors.

5. Impact resistance: China 304 stainless steel pipe has a strong impact resistance.
