Simple analysis of types of pipeline plugging
Type of pipeline plugging.
The first is the ordinary type. It is made of one layer, with a thickness of about 2mm. The second type is commonly used for closed water experiment, and it is used for inspection port. The biggest feature of this device is its small size and great elasticity, which can be put into a small inspection port without affecting the water plugging effect.
The third type is enhanced. It is made of two layers of nylon cloth sandwiched with one layer, with a thickness of about 3mm. It is the most commonly used model in municipal pipeline emergency repair.
The fourth type is thickening type. It is made of three layers sandwiched with two layers of nylon cloth, with a thickness of about 4mm. Its biggest characteristic is wear resistance and high bearing strength.
Fifth, high pressure. It is made of butyronitrile with a thickness of about 4mm. It can be used in sewage pipes, rainwater pipes, oil pipes, gas pipes and other pipes with high pressure.
Sixth: new materials. The material is PVC, light and easy to operate.
