Detailed explanation of heat exchanger tube sheet

Shell-and-tube heat exchangers are widely used in industrial plants. Different structures can be selected according to different operating conditions such as temperature, pressure and medium, such as fixed tubesheet heat exchangers (or fixed heat exchangers), floating-head heat exchangers, filled-tube heat exchangers, U-tube heat exchangers and so on. Tube sheet is one of the main parts of […]

Material selection for expansion joint of bellows compensator

The bellows compensator expansion joint is widely used in many industries. In addition to considering good compensation capacity, reliability is the key to the bellows compensator expansion joint. However, reliability is ensured through multiple links such as design and manufacturing. Any negligence of any link will lead to the reduction or even failure of the life of […]

2205 welding process considerations

1 The second-generation duplex stainless steel is generally called standard duplex stainless steel. Its composition is ultra-low carbon and nitrogen. Its typical composition is 22% cr + 5% ni + 0.17% n, compared with the first generation duplex stainless steel. 2205 further increases the nitrogen content and enhances the stress corrosion resistance and pitting resistance in an […]

How many valves are there? In which areas is the application?

At present, China’s valve industry has not only become the world’s number one in six: the world’s production area, the world’s first equipment level, the world’s largest production capacity, the world’s first valve production, the world’s first market demand, and the world’s largest overcapacity. Moreover, it is more than four and three fast: the largest number of […]

Advantages and disadvantages of stainless steel bellows

The stainless steel bellow is installed as a flexible pressure-resistant pipe in a liquid (gas) conveying system to compensate for the connection of pipes or machines and equipment. So what are the advantages of this stainless steel bellows to replace the rubber tube? The following is a brief introduction to the advantages and disadvantages of stainless steel […]

Characteristics, welding technology and requirements of stainless steel pipe fittings

Stainless steel pipe fittings are one kind of pipe fittings. They are made of stainless steel, so they are called stainless steel pipe fittings. They include: stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel caps, etc., according to the coupling method. It is divided into four types: socket type stainless […]

Seven factors affecting gaskets and packing seals

Factors affecting gasket and packing seal (1) Surface condition of sealing surface: the shape and surface roughness of sealing surface have certain influence on sealing performance, and smooth surface is beneficial to sealing. The soft gasket is insensitive to the surface condition because of its easy deformation, while the hard gasket is greatly affected by the surface […]

Brief introduction of stamping reducer

The stamping reducer is a reducer produced by a stamping process. The reducer has the advantages of stable structure, fast forming, high hardness, high pressure resistance, corrosion resistance, abrasion resistance and high temperature resistance. The size of the reducer is classified into: stainless steel reducer, alloy steel reducer, carbon steel reducer. Reducer, 10# reducer, 20G carbon steel reducer, […]
