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 […]

Moreover, it is more than four and three fast: the largest number of […]

Types, classification, quotation and characteristics of commonly used stainless steel pipes

Stainless steel pipe is a kind of hollow long steel. which is used as a pipeline for conveying fluids. such as oil. natural gas. water. gas. steam. etc. In addition. when the bending and torsional strength are the same. the weight is light. so Widely used in the manufacture of mechanical parts and engineering structures. Also […]

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 […]
