How to install industrial pipeline?

How to install industrial pipeline? Industrial pipeline installation works: Industrial pipeline can be divided into process pipeline and power pipeline. Process pipeline generally refers to the pipeline that directly transports main materials (media) for product production, also known as material pipeline; power pipeline refers to the pipeline that transports power media for production equipment. Thermal pipeline system The thermal pipeline is a pipeline that transports thermal medium such as steam or superheated water. Over laying form of heat pipeline Arrangement form There are two types of layout of thermal pipeline: branch and ring. Laying mode (1) Overhead laying. It is […]

Effect of solid solution on stainless steel pipe fitting and stainless steel f……

Stainless steel pipe fittings and flange manufacturers should consider the production cost of pipe fittings and flange, but also consider the factors of corrosion prevention and product quality improvement. Therefore, it is necessary to adopt solution process in the production process of stainless steel pipe fittings and flange to enhance the safety of pipe fittings and flange. Heat treatment process plays a crucial role in the quality and safety of pipe fittings and flange. It is understood that in order to save costs in the production of pipe fittings and flanges, a few enterprises did not take solution treatment, only […]

Can globe valve and gate valve be mixed?

What’s the difference between globe valve and gate valve? Structurally The gate valve can be tightly closed with the sealing surface depending on the medium pressure, so as to achieve the effect of no leakage. When the valve core and the sealing surface of the valve seat are always in contact and rub with each other when opening and closing, the sealing surface is easy to wear. When the gate valve is close to closing, the pressure difference between the front and back of the pipeline is large, which makes the sealing surface wear more seriously. The structure of gate […]

Comparison of corrosion properties of 316L and 2205 stainless steel

316L austenitic stainless steel and 2205 duplex stainless steel are widely used in the oil and gas industry because of their good corrosion resistance. However, due to the different composition and structure of the two materials, there are some differences in the corrosion behavior under the same corrosion environment. According to the corrosion characteristics of two kinds of stainless steel, the corrosion behavior of two kinds of materials under the same working condition was studied. Test plan Working condition and chemical composition See Table 1 for the working conditions selected in the comparative corrosion test and table 2 for the […]

Titanium alloy materials for aerospace fasteners

Fastener, as an important universal basic component, plays an important role in industry, and is called “the rice of industry”. Mr. Wu Guanghui, the famous chief designer of ARJ21-700 aircraft in China, also praised fasteners as “tens of thousands of types, groups, connecting structures, connecting systems, small things and big things [1]. According to the types, fasteners can be divided into 13 categories: bolt, screw, stud, nut, wood screw, self tapping screw, washer, rivet, pin, retaining ring, link pair and fastener assembly; according to the application field, fasteners can be divided into general purpose fasteners and aerospace fasteners. In the […]

What is vacuum heat treatment technology?

What is vacuum heat treatment technology? Vacuum heat treatment technology mainly refers to a new type of heat treatment technology combining vacuum technology and heat treatment technology. Among them, the vacuum environment of vacuum heat treatment refers to an atmosphere environment lower than one atmospheric pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum. Therefore, vacuum heat treatment actually belongs to atmosphere controlled heat treatment. Vacuum heat treatment means that all and part of the heat treatment process are carried out in vacuum state. Vacuum heat treatment can achieve almost all the heat treatment processes that can be […]

Annealing, normalizing and quenching of steel pipes

What is annealing of steel pipe? What are the types and uses of annealing? Answer: Annealing of steel pipe: annealing is a heat treatment process that heats the steel pipe to the temperature above or below the critical point AC1, and cools slowly with the furnace after holding for a certain time to obtain the structure close to the equilibrium state. Annealing type: according to the heating temperature, it can be divided into annealing above or below the critical temperature AC1. The former includes complete annealing, incomplete annealing, spheroidizing annealing, homogenizing annealing, and the latter includes recrystallization annealing and stress […]

Operation method, intention and application key of heat treatment process

Annealing Method of annealing operation: after heating the steel to AC3 + 30 ~ 50c or AC1 + 30 ~ 50c or below AC1 (relevant materials can be consulted), it usually cools slowly with the furnace temperature. Intention of annealing: Reduce hardness, improve plasticity, improve machining and pressure machining functions; Refine the grain, improve the mechanical function, and prepare for the next process; Eliminate the internal stress caused by cold and hot working. The key of annealing application: (1) It is suitable for forging and welding parts of alloy structural steel, carbon structural steel, alloy structural steel and high-speed steel […]

Analysis on the causes of assembly bolt looseness and anti looseness measures

Bolt connection is widely used in mechanical equipment, automobile, train, aerospace and other fields. It is the most basic structural form of fastener connection. For assembly plant, especially for construction machinery assembly plant, bolt connection has the advantages of convenient standardization, mass production, simple structure, low cost, convenient installation, easy disassembly and so on, and is the most widely used Application. When the equipment is in use due to vibration, high and low load change, impact or long-term working state, the bolt is easy to loose, which directly affects the operation performance of the equipment and reduces its safety and […]
