In the drum paring working area of ZOZEN Boiler, the steel plates finishing the rolling will accept the circular seam automatic welding here. After the polishing of welding seam, edge milling, chamfering and other pre-welding treatments, the floating rusts on the surface of steel plates are removed to avoid the generation of a large number of air holes in the welding seam, so as to ensure the welding quality.
In recent days, it has been very hot in Jiangsu province and the temperature of some areas is as high as 39 celsius degree. In spite of the high temperature, workers in the workshops of ZOZEN Boiler are still busy as usual. They are not afraid of hot weather, stick to their positions and use sacrifice and sweat to interpret the meaning of diligence. High temperature can not consume their enthusiasm and hot weather can not stop their steps. Thank all the workers who make sacrifice for the development of ZOZEN Boiler! Today, we focus on these ZOZEN workers under the high temperature and show great respect for them!
A boiler hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The main purpose of the hydrostatic test is to identify the tightness and compressive strength of the pressure components of the boiler, including but not limited to welding lines, flange joints and tube expansion joints, and visually observe the deformation of the pressure components. Practice has proved that the boiler hydrostatic test can detect defects in boilers, and the corresponding measures can be taken accordingly. Therefore, it is an important step and means to ensure the safe operation of the boiler.
