Specialized is engaged in the condenser, high and low, heat exchanger, heaters, oil machine, cold water

cooler replacement tube bundle and in transformation of one-stop services, copper tube for stainless

steel tube, 304/316 l stainless steel tube heat exchange tube with high efficiency, resistance to vibration,

anti fouling and corrosion resistant characteristics of stainless steel tube heat exchange tube completely

solve the problem in the past - to enhance heat transfer and reduce the wall thickness or use in the tube

wall of rolling spiral pipe stiffness of weakened, making reduce wall thickness - increased heat - increases

the stiffness is perfect and unified, at the same time has the characteristics of vibration resistance,

resistance to fouling.

  Condenser device of cold source of turbo-generator set is important, because of pollution of rivers and

lakes water system, condenser cooling pipe corrosion speed increase, caused the condenser frequent leak,

seriously affect the normal production. In particular, copper tube is easy to be exposed by ammonia ion and

sulfide corrosion. Meanwhile, because the inner wall of copper tube is not smooth and easy to adhere to

microorganisms and various kinds of dirt, the life of copper tube is greatly reduced.

2. Introduction of welded steel tube for tube replacement:

Condenser change bundle welded steel pipe is mainly used for thermal power, chemical industry,

steel, etc of the condenser and the heater replacement 304/316 l stainless steel tube, cold oil replacement

304/316 l stainless steel tube, water cooler replacement 304/316 l stainless steel tube, sampling cooler

replacement 304/316 l stainless steel tube, suction cooler replacement 304/316 l stainless steel pipe,

heat exchanger replacement 304/316 l stainless steel tube, shaft seal heater replacement 304/316 l stainless

steel tube, high pressure heater replacement 304/316 l stainless steel tube, low pressure heater replacement

304/316 l stainless steel tube, air preheater, air cooler and so on. Condenser to replace stainless steel tube

bundle in heat pipe specification: 12 ~ 76 mm diameter, wall thickness 0.2 ~ 3.0 mm, length scale and uncertain feet two.

The commonly used stainless steel tubes are 304, 304L, 316, 316L, 317, 317L.

Condenser change bundle welded steel pipe is adopted by the introduction of imported tube equipment

manufacturing, quality comparable to imported stainless steel pipe or slightly stronger, the microstructure of

weld and parent metal, mechanical properties such as strength slightly better. Due to the thickness and uniformity

of stainless steel tube strip, the surface is smooth and smooth, and its quality is better than that of the same kind of

cold dial and hot rolled seamless stainless steel. The elongation rate is greater than 35%, and the hardness is

small and easy to expand.

3. Replacement of stainless steel pipe description:

Condenser change bundle classification of stainless steel pipe specifications: light stainless steel pipe, stainless steel

tube, stainless steel bellows, 201 stainless steel screw tube, 304 stainless steel screw tube, 316 l stainless steel threaded

pipe, stainless steel U tube, stainless steel finned tube, etc., our company stainless steel tube heat exchange tube is

researched and developed and selects the import high quality stainless steel pipe, stainless steel strip, cold, hot forming

and strip, after rolling, welding, inspection, rolling, grinding, solid fusion, polishing a dragon 304 stainless steel tube, 316 l

stainless steel tube production line for processing; According to the actual needs of users, different pipe diameter,

wall thickness, length form and other stainless steel tube specifications are produced.

4. Stainless steel tubes have the following advantages:

(1) Stainless steel tube in the heat pipe heat transfer performance is good, because of thin-walled stainless

steel tube wall can use 0.5 0.7 mm stainless steel tube, improve the overall heat transfer performance,

under the same heat transfer area, the overall heat transfer coefficient of 2.124 and 8.408% higher than that of copper.

(2) Due to the use of high quality stainless steel, such as AISl304 and 316l, the pipes have a higher hardness

and the steel degree of the stainless steel pipe is obviously improved. Therefore, it has strong impact performance

and anti-vibration performance of high temperature steam.

(3) As the inner wall of the tube is smooth, the thickness of the bottom layer of its boundary layer is thinned,

which not only intensifies the heat transfer, but also improves the anti-fouling performance.

(4) The heat exchange process performance is good, tube expanding process, the traditional tolerance agree

with copper pipe, stainless steel pipe diameter does not need to change the tube plate hole machining tolerance,

conducive to the scene to direct selection, particularly convenient old condenser unit change bundle.

(5)304/316l stainless steel pipe is economical and economical. Under the same heat exchange area, the cost

of the stainless steel tube is about 80% of the copper tube cost, and can be changed directly to replace the tube bundle.

(6) In order to eliminate the welding stress, heat exchange tube in a protective gas to 1050 ℃ high temperature heat treatment.

(7) All tubes are checked by differential pressure method, and the pressure test is to 1.0Mpa, and no pressure drop for 5 minutes.
