There are three butt methods for seamless square steel pipes, namely electric welding butt, pipe hoop and trench butt, and flange butt:
1. Welding and docking method
Welding and butting two seamless square steel pipes is a common butt method. This method is more time-consuming, but it improves overall quality. Water will not leak after welding.
2. Pipe hoop and pipe trench docking method
Pipe clamp-to-trench jointing was a popular method in the past. It is easy to construct. You only need to process two seamless steel pipes into the trench, and then use pipe hoops to connect them. This method requires the use of high-quality pipe hoops. , Poor quality pipe hoops are very easy to seep, leaving potential safety hazards for subsequent users.
3. Flange docking method
Flange docking is generally used at docking gate valves.
