Cauze de perforare și scurgere a flanșei oarbe a rezervorului de stocare a butanului

There are 8 tanks in the butane plant of the natural gas treatment plant. The tank bottom is 5m high from the ground and of the same size, belonging to the pressure vessel. The storage medium is mixed butane (mixture of n-butane and isobutane) and isobutane (product), which was put into use in March 2008, and is a recycled pressure vessel. The tank parameters are as follows: Inner diameter of tank body: 2400mm; Tank length: 11542mm; Tank volume: 49.50m3; Design pressure: 1.58MPa; Blind flange size: DN50. In October 2008, the whole plant was shut down for internal and external inspection […]

Analiza și prevenirea eșecului de Hastelloy C-276 Heat Exchange Tube

Hastelloy C-276 heat exchanger tube in service corrosion failure occurred, the weld area significantly thinned, the weld localized small holes. Through metallographic, scanning electron microscopy, spectral analysis and other means of analysis of the failure of the C-276 welded tube analysis. The analysis results show that only the weld was cold drawn, improper welding process and subsequent imperfect solution treatment is the main reason for the reduction in corrosion resistance of the weld area. Finally, the corresponding preventive measures were proposed. 0. Introduction Hastelloy C-276 material has good corrosion resistance, so it is widely used in chemical pressure vessels [1]. A chemical company […]

Studiu privind procesul de tratament termic industrial al oțelului inoxidabil 304

In order to realize the bright heat treatment of 304 stainless steel evaporator, a protective atmosphere is applied to the small mesh belt heating furnace. Through the combination test of several groups of process parameters, the hydrogen flow rate is 4.5-5.0 m3/h and the pressure is 0.2 MPa; Heat treatment temperature 1060 ± 10 ℃; Holding time 6.5 min; The process parameter of mesh belt speed is 180mm/min. The influence of heating temperature and heating time on the structure and performance of evaporator was discussed. Evaporator is an important component of the four major components of refrigeration, low-temperature condensing liquid […]

A Comprehensive Guide To Plates Of Middle Thickness: Everything You Need to Kn……

What is medium thick plate? The steel plate is a flat steel which is poured with molten steel and pressed after cooling. Medium-thick plate refers to the steel plate with thickness of 4.5-25.0mm, the thickness of 25.0-100.0mm is called thick plate, and the thickness over 100.0mm is extra thick plate. Medium thickness plate generally has high comprehensive mechanical properties. Mechanical properties required are: strength, plasticity, hardness, impact toughness, stiffness, etc. Process performance requirements are: welding performance, hardenability, processability, weather resistance, corrosion resistance, wear resistance, fatigue resistance, high temperature characteristics, low temperature characteristics. corrosion resistance, wear resistance, fatigue resistance, high temperature […]

Tratamentul termic al oțelului inoxidabil în conformitate cu standardul JIS G 4303

Stainless steel is Cr content greater than 10.5%, C content of less than 1.2% of the alloy steel with high corrosion resistance. According to the steel’s room temperature organization, stainless steel is divided into five categories: austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, austenitic-ferritic stainless steel, and precipitation-hardening stainless steel. The following 5 categories of stainless steel heat treatment according to the Japanese JIS G 4303 is introduced. Heat treatment of austenitic stainless steel Solution heat treatment Solution heat treatment is the elimination of martensite in steel and steel strain, the solid solution of carbide, so that the […]

Application of flexible design of heat pipe in Engineering

Thermal expansion and cold contraction of thermal pipeline is a common phenomenon in engineering, but the key to design is to fundamentally reduce the stress caused by thermal expansion and cold contraction. The thermal pipes in the project are compensated by self bending according to the layout characteristics of the pipes. If this method can not eliminate the stress of the pipes, it needs to be solved by adding compensators on the pipes. In this paper, the common methods to eliminate the stress of the heat pipe and the characteristics of the compensator are described. Through the flexible analysis of […]

Determinarea grosimii flanșei oarbe cu diametru mare

Blind flange set in the requirements of the pipeline system or equipment need to cut off the part, such as equipment before and after the cut-off valve or between the two flanges, the main role is to completely isolate the process media to prevent the shut-off valve due to poorly closed to affect production and cause accidents. From the outside, generally divided into spectacle blind flange, blind flange and pad ring (blind flange and pad ring for each other blind pass). Usually DN600 and below the thickness of the figure-8 spectacle blind, blind flange and pad ring can be obtained […]
