tube sa214 for boiler

After the pipeline pressure test of the tube sa214 for boiler boilers, valves, meters and other installation, cleaning up outside the boiler, close the manhole, hand hole, then pressure test in accordance with the relevant provisions of the "Steam Boiler Safety Technology Supervision" of. Specific test as follows: 1, should be ready before the hydrostatic test the following: (1) for internal cleaning and inspection of the surface of the test portion. (2) Check the clogging of the tubes. (3) mounted to verify compliance with the pressure gauge (not less than 2). (4) mounted good deflation valve and drain line. 2, the hydrostatic test shall meet the following requirements: (1) hydrostatic test shall be carried out when the ambient temperature is higher than 5 ℃, or should be protected from freezing, temperature should be higher than the ambient water pressure dew point temperature, generally 20 to 70 ℃. (2) when the water pressure up to the working pressure should be temporarily stopped a boost, check the various parts for leaks, and then rose to the test pressure for 20 minutes after the pressure back down to work, to be checked. During the inspection the pressure should remain unchanged. 3, meet the following criteria to be acceptable: (1) no water mist on the pressure-receiving element and the metal wall and welds. (2) Expansion mouth bead does not drip down when the operating pressure. (3) pressure test, no residual deformation. These are the work of the boiler pressure test can help you better understand the boiler equipment, hope this can be helpful to you in the future use.

Factors SZS Gas steam tube sa214 for boiler air consumption: factors SZS gas boiler gas consumption of steam at present, the type of gas boilers on the market range, the price is also different. Thermal efficiency between 85% to 95%, which is different with different manufacturers of production of thermal efficiency. Small boiler factory price is relatively low, but poor results. A price of a stock is really not false, so the time of purchase must be to get into a detailed comparison of.

Advantages and disadvantages of gas-fired tube sa214 for boiler gas boiler is a clean burning natural gas for industrial boiler energy section of industrial production output of hot water and steam. After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, etc., should be transported from the gas boiler, coal-fired boiler broke thriving situation. Compared with conventional oil-fired boilers, coal-fired boiler, gas boiler has incomparable advantages, mainly in the following aspects: 1, and the consumption gas boiler artificial hydroelectric low cost; 2, or energy of the flue gas boiler condensate promotion of technology, it greatly enhance the thermal efficiency further, when the boiler flue gas temperature is reduced to 80 degrees or less, up to 95% efficiency; 3, clean environment, boilers small footprint, low failure rate, can be significantly improved use the unit on-site environment, adequate supply and lower prices, environmental requirements higher cost areas of comparative advantage of obvious; 4, due to the use of this type of boiler is clean energy, it will not produce combustion in the furnace at the time of soot and dust, so the operating life than other types of boiler long. However, due to the environmental advantages of natural gas and energy in a growing proportion of supply and demand and Jiazhiguilv bound to make the country in the future and gradually it with other primary energy prices linked to float, its long-term price trend will gradually open. In addition natural gas shortages in some areas or seasonal shortages also affect the reasons for its further promotion. On the whole, the use of gas-fired boiler more good than harm, to promote the use of gas-fired boiler is still the trend. Zheng pot shares as a professional supplier of boilers, gas-fired boiler in terms of a series of development and exploration, successfully developed the first low nitrogen gas boiler Henan Province, have made outstanding contributions to technological innovation and gas boiler.
