According to my country's regulations: gas-fired steam boilers are special equipment, so everyone must operate in strict accordance with the specifications when using gas-fired steam boilers to avoid safety accidents. Regular inspections of gas-fired steam boilers are very important. Zhengzhou Fangkuai boiler manufacturers explain some of the problems that are easy to find during regular inspections of gas-fired steam boilers to help everyone use the boiler better.
The problems of internal inspection: one is the existence of cracks, and the other is the deformation of some compressed parts. The first problem is a major obstacle to the operation of the boiler. When necessary, welding or replacement is the main way to solve it. To avoid corrosion cracks, it is necessary to strengthen the monitoring of water quality in daily operation. The second type of problem is generally caused by excessive temperature, uneven heating, and insufficient component strength. Strengthening the management of water quality and doing a good job in timely drainage can effectively reduce component deformation.
The inspection methods mentioned in the regular inspection probably include visual inspection, non-destructive inspection, light inspection, etc. Visual inspection: A method to observe whether there is a problem with the boiler by eye. This method is suitable for the condition that no other equipment exists in the early stage of the boiler inspection. When the boiler has obvious external defects, the visual inspection method is more suitable. Compared with other inspection methods, the visual inspection method has the advantages of simple and intuitive, but the visual inspection method has certain requirements on the technical level of the inspectors. Non-destructive testing (NDT) refers to the thermal, electrical, acoustic, magnetic, optical and other reactions caused by the abnormal structure or defect of the material without damaging the performance of the measured object and the internal structure of the measured object. Using physical or chemical methods, using modern technology and equipment, the internal and surface structure, performance, state and type, performance, quantity, shape, location, size, distribution and changes of inspection and testing methods have been studied. Non-destructive testing is generally divided into ultrasonic testing, magnetic particle penetration, X-ray testing, etc. Magnetic particle testing is suitable for boiler parts that are easily magnetized and easily demagnetized, and has incomparable advantages over visual inspection. For the fillet welds of boilers, ultrasonic testing is generally used. This method can be used to detect whether the weld fusion meets the standard. X-ray inspection can accurately identify the internal defects of the boiler structure, and objectively evaluate the internal defects through the radiographic film.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.
Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs. In the future, Zhengzhou Fangkuai Boiler Sales Co., Ltd. will continue to focus on overseas market demands, continuously optimize its product and service system, facilitate the high-quality development of the global textile industry with professional and reliable products, and steadily enhance the brand’s competitiveness and influence in overseas markets.
Trust stems from quality
At the beginning of the new year, Fangkuai Boiler and a leading domestic new energy company have reached another important cooperation, successfully signing an order for a total of 500 steam tons.
