Bolted and welded flange connections are two common pipe connections that are suitable for different application scenarios. Which connection method is chosen depends mainly on specific requirements, including strength, tightness, ease of installation, cost and other factors.

Bolted connection is a kind of connection method that connects two or more parts together by bolts. This type of connection is relatively cheap, easy to install, easy to disassemble, suitable for the need of lightweight as well as smaller size and lower strength connection occasions. However, it should be noted that if the connection needs to withstand a large pressure, such as high pressure or ultra-high pressure, only using the bolted connection may not meet the strength requirements.

Welded flange connection is a connection method in which two flanges are joined together by welding. This type of connection is usually used where high strength, high tightness and long-term stability are required. Welded flange connections are the preferred connection method in many industrial applications due to their high strength, good sealing, corrosion resistance, and durability. However, the cost of welding flange connections is relatively high, and some environmental impacts may occur during the welding process.

Overall, if cost and ease of installation are considerations, bolted connections may be a good choice. However, if high strength, high tightness and long-term stability are required, then welded flange connections may be a better option. Which method to choose needs to be decided according to specific application scenarios and requirements.

Please note that the above information is based on general information, and the actual selection also requires reference to specific industry standards and engineering knowledge.
