Welding repair and plugging method in flange pressure plugging

Welding repair is a method to plug the leak directly or indirectly. This method is suitable for pipes with good weldability and high medium temperature. It is not suitable for inflammable and explosive occasions. Non-stop pressure seal

1. Direct welding

The method of filling and welding the leak with electrodes directly is called direct welding method. This method is mainly suitable for plugging leakage in low pressure pipelines.

2. Inter-welding

The welding seam is not directly involved in plugging leakage, but only plays a role of fixing the cap and sealing parts, which is called inter-welding method. Inter-welding method is suitable for plugging leakage in places with high pressure, wide leakage area, strong corrosiveness and small wall rigidity.

3. Welding Pad Method

The method of cladding the leak in the metal cavity to cure the leak is called the cladding method. This method is mainly applicable to the sealing of flange, thread, valve and pipeline parts.

4. Welding Cover Method

The metal cover of the cover body is used on the leak site, and the leak can be cured by welding and fixing. It is suitable for the leak stoppage parts with larger defects. If necessary, a drainage device can be installed on the cover.

5. Inverse Welding Method

According to the principle of seam shrinkage, the leakage cracks are welded one by one in reverse, so that the cracks shrink without leakage, which is beneficial to the formation of weld beads, is called reverse welding method for short, also known as sectional reverse welding method. This method is suitable for plugging leakage in low and medium pressure pipelines.
