Price:Stainless steel tank
Product introduction:Suzhou Shanghai stainless steel water tank manufacturers, manufacturers of stainless steel water tank, fire water tank, the price of stainless steel heat preservation water tank, water tank, washing tank, stainless steel cylindric
1 water cycle
The utility model has the advantages of fast heating (dynamic heating), stable performance, long service life, good safety, and is favored by the market. Disadvantage is the high cost of production.
2 built in coil type
The utility model has the advantages of quick heating and short heat exchange time. The disadvantage is due to the thickness of the coil material, such as the impact of a small number of products have coil corrosion, leakage of hidden.
Quality of stainless steel water tank
With the increasing competition in the market for 09 years, compared with the same period last year, the domestic market price of stainless steel water tank pressure decreased more than 30%, mainly the production of raw materials such as copper, stainless steel water tank 304, prices continue to rise, copper from 29 thousand yuan per ton rose to 50 thousand yuan per ton. In this case, no matter what kind of heat transfer structure of the water tank, the water tank capacity sufficient, sufficient material to ensure the material quality, is the key to ensure the quality of water tanks. In order to save the cost of production, some stainless steel water tank production enterprises adopt the measures and means to reduce the quality of the water tank.
1, liner 304# stainless steel material thickness thinning
Good stainless steel water tank capacity sufficient, material enough, the thickness of the liner between 0.90-1.95mm, quality assurance.
The quality is not reduced, the water tank products, liner with the 0.90-1.0mm, the actual 0.75mm; the use of 1.3-1.5mm, the actual 1.15mm; the use of 1.7-1.91mm, the actual 1.45mm. Cost advantage is obvious, of course, different quality. The stainless steel water tank can be compared with the same material tank, and can also be used to dissect the water tank.
2, with a low price instead of 304# stainless steel material of stainless steel liner production as we all know, there are many kinds of stainless steel, 316#, 304#, 301#, 202#, 201#, 200#, 430#, 444# and other types, different types of stainless steel quality such as corrosion resistant properties vary greatly, of course the price difference, per ton of different kinds the stainless steel price difference of thousands of yuan to 10000 yuan. With the lower price of stainless steel instead of 304# stainless steel production of water tank products, layman generally do not come out. However, the product after a period of time, the problem came out, because the material corrosion of stainless steel water tank Water Leakage, which brings unnecessary losses to the user, in turn, will bring considerable adverse impact to the sales unit.
3, stainless steel water tank volume is not up to the actual value of volume
Because the stainless steel water tank in the middle of the box, the user can not directly see, this provides opportunities to part of the water tank liner production enterprises, the actual volume of production is much smaller than the standard size. In this way, to achieve the purpose of less material. The normal volume should be less than the value of ninety percent.
4, the use of low-density insulation materials
Insulation material and heat preservation time have a great relationship, under normal temperature for 24 hours in the stainless steel tank cooling control at 5-7 C standard. Different manufacturers use the water tank insulation materials are also different, and some use a lower density of insulation materials, insulation effect is very rare to ensure that stainless steel, which virtually increases the energy consumption of heat pump water heater.
5, stainless steel water tank shell with thin material production
Stainless steel water tank shell and the bottom of the end cover with thin material production, and even some of the water tank products, simply do not have the bottom end cover. Such an approach in addition to the impact of the appearance of the box, the water tank is easy to produce stainless steel rust, and the product is easy to cause damage during transport, but also shorten the service life of the tank.
6, built-in stainless steel water tanks, coil material, length, thickness of the coil is not a built-in two kinds, one is the copper coil, the other is a stainless steel coil. That kind of material coil good?. The reason is that the built-in copper coil is too thin and easy to cause leakage, the copper coil is still the most widely used in the market. Stainless steel coil to the market for a long time, there is no problem, to be tested and recognized by the market.
The heat transfer performance of copper tube is obviously superior to that of stainless steel tube, and the heat transfer effect is about 20 times of that of stainless steel. As everyone knows, the air conditioner is connected with copper pipe, the air conditioner from birth to now has a history of several decades, technology has been very mature, although stainless steel is cheaper than copper, but no air conditioning manufacturers to adopt stainless steel tube. The reason is that air conditioners and heat pump water heaters are "three points products, the installation of the" half of the product, the installation of tune
