Butt joint method of Q345B seamless square tube

When applying Q345B large-diameter seamless square pipe, pay attention to the relevant application objectives and application methods and characteristics. The specific performance is that the main purpose is relatively wide, and it can be applied anywhere. Generally, it is interrupted with other stainless steel plates. Application, the whole process of common butt joints also has to show related problems, because the part of the seamless square tube in the square steel tube is as large as the part of the seamless tube in the seamless steel tube. Sometimes it is not good to not have him in shaping. So now that the seamless square tube is often displayed in a docking method, what is its docking method?
 
There are three butt joint methods for seamless square pipes, namely electric welding butt joint, pipe hoop butt joint and flange butt joint
1. Welding butt joint method
Welding and butting two Q345B seamless square pipes is a more common butt joint method. This type of method is more useful, but it is true for the overall quality, and it is not easy to seep water after electric welding.
2. Pipe hoop pipe trench butt joint method
Pipe coupling trench butt joint is a popular butt joint method in the past. The engineering construction is convenient. Only two seamless steel pipes are used to produce the trench, and then the joint is interrupted by the pipe clamp. This type of method requires the application of good quality pipe clamps. , Poor quality pipe clamps are very easy to seep water, leaving a safety hazard for users later.
3. the flange connection method
Flange butt joints are generally used at butt gate valves.
