Stainless steel for pressure vessels and its welding characteristics. The so-called stainless steel refers to the addition of a certain amount of chromium in the steel to keep the steel in a passive state and free from rust. Liaoning Horizontal fuel oil steam generator For this purpose, the chromium content must be more than 12%. In order to improve the passivity of steel, it is often necessary to add nickel, molybdenum and other elements that can passivate steel into stainless steel. Stainless steel is generally referred to as stainless steel and acid resistant steel. Stainless steel companies do not have certain acid resistance, and acid resistant steel generally has a good stainless property. small-scale Horizontal fuel oil steam generator factory According to its steel structure, stainless steel can be divided into four categories, namely, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and austenitic ferritic duplex stainless steel.

In daily life, pressure vessels are divided into those in contact with fire sources and those not in contact with fire sources. In fact, pressure vessels also need anti-corrosion in daily life. For the anti-corrosion of pressure vessels, we need to do the following. Liaoning Horizontal fuel oil steam generator First, check the structure of its equipment components, safety valves, bursting discs, emergency vent valves and other collective Yixing pressure tanks to see if there is any corrosion. Once corrosion occurs, measures should be taken in a timely manner. Anti rust paint should be painted before the equipment is used. After use, it should be cleaned in a timely manner to ensure the cleanliness of the equipment. small-scale Horizontal fuel oil steam generator factory Secondly, it is necessary to protect the safety device of the pressure vessel. The safety device is an important device of the pressure vessel. Good protection should be carried out. Good maintenance should be carried out before and after use. It is necessary to apply lubricating oil and antirust paint.

The long-term use of gas-fired boilers will inevitably lead to problems of one kind or another. However, the working principle of gas-fired boiler is complex, and the price of gas-fired boiler is particularly high, so it is necessary to select high-quality gas-fired boiler manufacturers and companies with good after-sales service. Liaoning Horizontal fuel oil steam generator In addition, what should we do if the gas boiler fails? As the gas-fired boiler involves the construction of gas and lines, the professional installation personnel of the manufacturer must check the installation at home, and the professional personnel shall install it. Improper installation will bring a series of problems for future use. small-scale Horizontal fuel oil steam generator factory The existing pipes and radiators in China need to be observed by professional engineers and installation personnel to determine whether they can continue to be used. If the service life is long, the heating system may scale more. It is generally recommended that the user replace it to obtain better heating effect.

To understand the advantages and disadvantages of hot blast stove and hot water stove, we should start from the working principles of the two boilers. The hot water boiler can increase the indoor temperature by burning hot water, circulating hot water, heat dissipation, etc. General purpose (radiators, floor heating pipes, water heating air conditioners are generally used for heating in families, enterprises and institutions). Liaoning Horizontal fuel oil steam generator The hot blast stove can increase the indoor temperature by heating the air. Generally, a hot channel wind belt is required. It is generally used for workshop, breeding, planting and special heating or drying. Most areas in northern China are cold, such as the three northeastern provinces, Inner Mongolia, Xinjiang and other cities. The colder temperature is more than minus 40 degrees Celsius. There are hot water boilers and steam boilers for heating. Its disadvantage is that it is afraid of circulatory system failure or power failure. small-scale Horizontal fuel oil steam generator factory Once the power failure exceeds two to three hours, if the insulation is not good, the pipeline will freeze. The heating of hot blast furnace is not frozen, and the temperature can be set. It can save 40% energy than hot water heating and 50% energy than steam boiler heating. This comparison is practical. The hot blast stove does not need to apply for a use certificate, the steam boiler and pressure hot water boiler need to apply for a use certificate, and the functional department also needs to carry out annual inspection every year, but also has to bear the cost.
