There are many ways to connect seamless pipes, the most common ones are the following:
1. Butt welding connection
Butt welding is one of the most commonly used seamless pipe connection methods. Butt welding can be divided into manual butt welding and automatic butt welding. Manual butt welding is suitable for the connection of small diameter, low pressure seamless steel pipes, while automatic butt welding is suitable for the connection of large diameter, high pressure seamless steel pipes. Butt welding connection has simple structure and good reliability, and is suitable for chemical industry, electric power and other industries.
2. Threaded connection
Threaded connection is a common seamless pipe connection method. It can be divided into two ways: internal thread connection and external thread connection, which are suitable for low-pressure transportation systems, such as tap water, natural gas, etc. The threaded connection is simple, easy to use, and easy to disassemble and maintain.
3. Flange connection
Flange connection is a common high-pressure pipeline connection method, suitable for high-pressure, high-temperature, and large-diameter seamless steel pipe connections. There are many types of flanges, including flat welding flanges, butt welding flanges, threaded flanges, etc. You can choose different types of flanges to meet different engineering needs. Flange connection has the advantages of reliable connection and good sealing, but it is difficult to install and maintain.
4. Plug-in connection
Plug-in connection is a simple and convenient seamless pipe connection method. It can be divided into two methods: cap plug-in and sleeve plug-in. Suitable for the connection of small and medium diameter, low pressure seamless steel pipes. Plug-in connection has the advantages of simplicity, convenience and no need for special equipment.
In short, the choice of seamless pipe connection method should be based on comprehensive considerations such as project requirements, pipe type, pressure level, use environment and safety requirements. Only by selecting the appropriate connection method can the normal operation and service life of the pipe be guaranteed.
