Performing a water pressure test before the boiler is officially started can grasp the problems existing in the boiler early and deal with them in a timely manner. Take oil-fired gas boilers for example.
The hydraulic pressure test of oil-fired gas boilers is generally divided into a hydraulic pressure test and a super-hydraulic test of rated working pressure. The overpressure test pressure of the boiler body is 1.25 times of the rated working pressure of the boiler shell or the rated pressure plus 0.4 MPa.
If one of the following situations occurs, our oil-fired gas boiler also needs to perform an overpressure water pressure test.
1. Before the newly installed boiler starts trial operation;
2. After the boiler's pressure parts have undergone major transformation or replacement;
3. The boiler in operation is performed every six years (combined with overhaul).
If one of the following situations occurs, our oil-fired gas boiler needs to perform a working pressure and hydraulic test.
1. Generally, after large or small repairs or rush repairs, the hydraulic pressure test of the working pressure is performed after the repairs;
2. If the furnace is shut down for more than 30 days, a hydraulic pressure test of working pressure must be performed before ignition.
Previously we said that it was better to perform a hydraulic test for the sake of safety. However, whether it is a steam boiler or a hot water boiler, after the boiler is installed, a hydraulic pressure test (that is, water pressure) must be performed. After long-distance transportation, loading, unloading, and installation, collision and damage are unavoidable. Boiler defects can be found through hydraulic tests, and appropriate measures can be taken in time to ensure the safe operation of the boiler.
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.
