Pressure vessel safety points (Ⅰ)

Shandong Tanglian always adhere to the "quality-oriented", with high-quality product quality and perfect after-sales service to win the trust of customers and a high degree of praise, the product sells well at home and abroad. The following is a brief introduction about the safety points of pressure vessels:

Pressure vessels in the working process to withstand the pressure, temperature and other parameters are high, once the safety problems, the consequences will be extremely serious. Therefore, the safety of pressure vessels has been the focus of attention of various industries. This paper will be from the design, manufacturing, testing, use and other aspects, summarize the pressure vessel safety points for reference.

1. Design stage

In the design of pressure vessels, should be based on the use of the environment, the nature of the medium, process device requirements and other factors, a reasonable choice of pressure, volume, materials and other parameters, and in the vessel design process to fully consider the safety factors. For example, in the design of pressure, according to the strength of the container material, use conditions and other elements, to determine the appropriate pressure range, to avoid explosion and other accidents due to overpressure; in the design of the volume, should be fully considered in the medium volume change, container material tensile deformation and other factors, to avoid rupture and other safety issues due to the change in the volume of the container.

2.Manufacturing stage

When manufacturing pressure vessels, professional manufacturing equipment and advanced technology should be adopted in accordance with the specification requirements to ensure that the quality of the vessel meets the national standards and user requirements. In order to ensure the safety of the vessel, the manufacturing process should focus on the following key points: first, control the quality of materials to avoid material defects, cracks and other quality problems; second, strengthen the welding quality control to avoid rupture of the vessel due to poor quality of the weld or cracks; third, strict pressure test to ensure that the vessel can withstand the rated pressure and temperature under normal conditions.

3.Use stage

In the use of pressure vessels, the design, manufacture and operation regulations should be strictly observed to ensure the safe operation of the vessel. The following points must be strictly observed: first, regular inspection and maintenance of the vessel to avoid corrosion, fatigue and other potential safety hazards within the vessel; second, monitoring the vessel pressure and temperature parameters to avoid accidents caused by overpressure and over-temperature of the vessel; third, standardized operation, prohibit violation of the operation of the vessel, to avoid safety accidents due to operational errors.
