Pressure vessel manufacturing process and its quality control research

Pressure vessel equipment in many industries in China have a wide range of applications, because the pressure vessel needs to be in a long time in the high temperature and high pressure of the harsh working environment, and the internal holding materials have certain specificity, if you can not guarantee the quality of the pressure vessel, resulting in corrosion of the metal, weld cracking and other quality problems, it is easy to lead to the emergence of the consequences of the serious safety accidents. Based on this, this paper from the actual situation, first of all, explains the pressure vessel […]

The Main Factors and Preventive Measures for the Failure of Plate Heat Exchang……

The plate heat exchanger is a new type of high-efficiency heat exchanger. It has the characteristics of high heat exchange efficiency, small heat loss, and compact and lightweight structure. But its use also fails due to its sealing gasket, blockage, scaling, and corrosion of the medium used. This article analyzes the causes and preventive measures for the failure of the plate condenser. What is a plate heat exchanger? The plate heat exchanger is a new high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape stacked together. A thin rectangular channel is formed between various […]

Principles for drawing pressure vessel drawings

1. Principles of View Selection (1) The number of views (including directional views, cross-sectional views, etc.) should be minimized on the premise of clearly representing objects. (2) Avoid using dashed lines to represent the contours and edges of objects. (3) Avoid unnecessary repetition. 2. Drawing principles For processing, assembly, and other needs, each piece of equipment, component, or part should be individually drawn with drawings. The principle of not requiring separate drawings is as follows: (1) National standards, professional standards, and other standard components and purchased parts. (2) For riveted and welded parts with simple structures and whose dimensions, graphics, […]

Analysis of the Causes of Pressure Vessel Failure and Discussion on Preventive……

The industrialization construction has led to the rapid development of chemical enterprises in China. From a long-term development perspective, chemical enterprises face high safety risks, and once problems arise, they will have a relatively adverse social impact. The failure of production equipment caused by cracks in pressure vessels is a major safety hazard in major chemical enterprises. If not prevented as soon as possible, it will not only affect the normal operation of production equipment but also threaten the safety of residents, causing unnecessary economic losses. Exploring the causes of pressure failure and constructing preventive measures have become the focus […]

Application of penetration testing in non-destructive testing of pressure vess……

To comprehensively improve the operational safety and stability of pressure vessels as well as pressure pipelines, the analysis is carried out around the technical classification of quality inspection, focusing on the specific types of penetration testing and the application principles, and the applicable scope and application effects of different surface nondestructive testing techniques are analyzed through specific cases. The choice of penetration testing for nondestructive testing of containers not only can quickly locate the quality defects of containers but also can lay a good foundation for the safe operation of the overall pressure equipment. With the gradual improvement of China’s […]

Introduction to the stability design of titanium pressure vessels

There are stability problems in the regular design of titanium pressure vessels. We analyzes the main factors that cause the instability of pressure vessels due to internal and external pressure, and puts forward the measures that should be taken to control the instability of titanium pressure vessels. When the cylinder and head of titanium pressure vessel are subjected to compression load, circumferential instability or axial instability may occur. Circumferential instability can form several axisymmetric waveforms along the circumference of the cylinder or the circumference of the transition zone of the convex head; axial instability can appear along the axial corrugation […]

Discussion on Quick Estimation Method of Non-standard Pressure Vessel Quotation

According to the non-standard pressure vessel manufacturer’s own manufacturing equipment and technical capabilities, combined with examples to explore the rapid estimation method of non-standard pressure vessel production prices, the method can be widely used in the production of non-standard pressure vessels to quickly and accurately determine the price of competitive bidding, as well as reasonable control of the production process costs. What is a non-standard pressure vessel? Non-standard pressure vessel mainly refers to the industrial production for a specific application area, with a specific process function of the variable, not a series, for the gas or liquid to complete the […]
