Causes of tubular heater explosion
The selection of electric heating tubular element is generally stainless steel, and the materials of stainless steel are different depending on the specific use. The reasons for the explosion of heating tubular heater caused by general pipes are: the thickness of the pipe wall is too thin, the material selection is wrong or the quality is questionable, and the pipe is seamed. The thickness of the tube wall is generally 0.8 units. If it is too thin, it will easily be damaged by external forces or use. Stainless steel pipe can be divided into seam pipe and seamless pipe according to different processing situations. Seamless pipe is a whole pipe and is not easy to be damaged. The seam pipe is welded by steel bars, which is relatively easy to burst.
Electric heating equipment with electric heating tubes as the main cause of energy saving and environmental protection has gradually replaced the traditional combustion heating. Against the background of green development, it will usher in a good development prospect. As a manufacturer of electric heating pipes, Suwaie company believes that current electric heating companies should actively impact the high-end market.
Civilian electric heaters are often standard parts with relatively low unit value but large batch sizes. The industrial fields mainly include polysilicon production, oil and gas extraction, petrochemical and other fields. Electric heaters used in industrial fields are often part of industrial production systems and are non-standard parts. They have high performance requirements and relatively high unit values and profits.
The "2011-2015 Analysis Report on the Development Prospects and Transformation and Upgrade of China's Electric Heater Industry" released by the Industrial Research Institute shows that China's electric heater enterprises are mainly concentrated in the civilian sector. In some market segments, China has formed some market shares. Large and competitive leading enterprises. A large number of industrial electric heater manufacturers are concentrated in the low-end and middle-end markets, which are not able to enter the high-end market.
