Can stainless steel be used instead of a boiler s duct?

The copper tubes in the boiler can also be replaced with stainless steel tubes. However, compared with the service life of stainless steel pipes, it is relatively short, mainly because its corrosion resistance is not strong and there is no copper wall, so it can be replaced, but the service life is relatively short. The ducts of the boiler can be made of stainless steel tubes, like some steam generators now, all of which are made of stainless steel products.

The heating surface in the boiler furnace is mainly radiative heat exchange, the flue and convection tube bundle are mainly convective heat exchange, the water wall is radiant heat exchange, and the superheater is convective heat exchange. The boiler is a kind of energy conversion equipment, the energy input to the boiler is chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain thermal energy. The original meaning of pot refers to a container of water heated on a fire, and a furnace refers to a place where fuel is burned, and a boiler includes two parts: a pot and a furnace.

The hot water or steam produced in the boiler can directly provide the required heat energy for industrial production and people's lives, and can also be converted into mechanical energy through steam power devices, or converted into electrical energy through generators. The boiler that provides hot water is called a hot water boiler, which is mainly used in life, and there are also a small number of applications in industrial production. The boiler that produces steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power stations, ships, locomotives, and industrial mines.

Can stainless steel be used instead of a boiler's duct? In fact, this can be used, but there must be advanced technology, and the quality of stainless steel must be particularly good, in order to achieve the actual effect, if the use of quality is inferior, then it will definitely not work.

Stainless steel can not replace the conduit of the boiler, because the inside of the boiler is a copper tube, he has a special thickness, must be used uniformly. The diameter and thickness of stainless steel do not match.

Boilers are divided into fire tube boilers and water tube boilers. The ducts of the boiler are subjected to pressure, temperature. The boiler duct should be connected to the boiler barrel. The pot barrel is made of steel, and the connection should be sealed and not leaked. How can stainless steel be replaced? In general, it is not replaceable.

Yes, but the cost is too high, the requirements for water quality have changed, and the requirements for chloride ions in stainless steel are high.

This depends on your boiler parameters, but generally these main parts are not recommended to be changed at will without technical verification, and you can't inspect the boiler if you change it. Moreover, the new pipe and the old pipe are not easy to dock, the two materials are different, and it is difficult to weld together.

The boiler is a special equipment, and the installation needs to be reported to the relevant departments for inspection, what material of pipe is used, and how large the caliber are all specified and cannot be changed at will. As for whether it can be used, it depends on the actual situation and the regulations of the inspection department.

Your question is not accurate enough, especially the boiler model, because there is a lot of information in the boiler model, and in addition, it is not clear which conduit it is. The pressure crossing is a special equipment, and there are strict technical requirements for the selection of materials, which cannot be used at will, and the material of the pipe must meet specific requirements. If you are using a pressureless boiler, the technical requirements are less, but there are also technical conditions in welding, the two materials are generally not welded, if you must weld, then you must also heat treat different materials, and then weld with special-shaped welding rods.

There are statutory requirements for boiler materials, so don't look for something to replace them. The safety supervision committee can't pass it.

1. Waste pipe (pipe blank): The raw material of stainless steel pipe blank used in production is called waste pipe. 2. Pipe cutting:

When producing stainless steel pipes, it is necessary to cut off the head and tail, including the flat heads at both ends of the waste pipe, the cutting of intermediate products and the cutting of finished products during feeding. Scrap of steel pipes is produced when cutting steel pipes. 3. Pickling and degreasing:

Oxidation of the surface of stainless steel pipes after heating due to high temperature.

It's good if you can find a web page and a mobile phone that can be played on it. If it's fun, there's no standard. VQD computer web page or mobile phone are all OK, oh, with snacks to play with this is no big problem.

Hello dear! Glad for your question! What kind of boiler with stainless steel tubes:

The boiler is mainly alloy steel when the temperature is high and the pressure is high, and stainless steel is still the main boiler waste heat boiler, which should be used more when it is resistant to acid and alkali fluids. The working environment is generally divided into dry burning and liquid heating, if it is dry burning, such as for ovens, air duct heaters, can be made of carbon steel, can also be made of stainless steel 304. If it is to heat liquid, if it is water, use stainless steel electric heating pipe, this stainless steel is generally made of stainless steel 304, if it is oil, carbon steel or stainless steel 304 material can be used.

If it is a weakly acidic and alkaline liquid, stainless steel 316 can be used. If there is only a strong acid in the liquid, stainless steel 316, PTFE or even titanium tubes should be used. 2. Determine the power of the heating tube according to the working environment.

The power setting is mainly to dry burn the electric heating pipe and liquid heating, dry boiling, generally one meter length of the pipe to do 1kw, heating liquid, generally one meter length of the pipe to do 2-3kw, the maximum does not exceed the shape of the heating pipe according to the customer's electric heating equipment. The shape of stainless steel heating pipes is ever-changing, the simplest is straight bar, U-shaped and then special-shaped. Specific shapes of electric heating pipes are used.

4. Generally, the wall thickness of the heating pipe is used, but according to the working environment of the heating pipe, such as the case of high water pressure, it is necessary to use seamless stainless steel pipe with thick wall thickness to make electric heating pipe5. That lies in the internal materials, and the two most important materials inside are insulating powder and alloy wire. Insulating powder, the poor will use quartz sand, and the good will use insulating modified magnesium oxide powder.

In addition, alloy wire, generally made of iron-chromium-aluminum, can be made of nickel-chromium alloy wire according to the requirements and grades of pipe production. As the saying goes, you get what you pay for.
