Urban pipe water blocking air bags have a wide range of applications

The main uses of pipe water blocking air bags include pipe sealing, drainage pipe sealing, sewage pipe blocking, pipe blocking emergency repair, sewage pipe leakage plugging, drainage pipe leakage plugging, sewer pipe leakage blocking, cement pipe leakage blocking, drainage pipe detection, Pipeline water closure test, underwater plugging project, pipe mouth plugging, inspection well plugging technology. The product features of Walrus brand pipe water blocking airbags include multiple sizes, specifications, shapes, and more choices. They can be customized according to drawings. All water blocking airbags are equipped with standard inflation valves. Large water blocking airbags are equipped with There are replaceable valves for easy maintenance and replacement. All airbags can be folded for easy storage. Gas pipeline airbags have specific accessories and are divided into ordinary types, single-layer cord fabric, and double-layer cord fabric. The pipeline sealing airbag processing process includes plasticizing. , mixing, calendering or extrusion, molding and vulcanization and other basic processes. Each process has different requirements for the airbag, and is equipped with several auxiliary operations. In order to add various required ingredients into the rubber, the raw rubber must first be masticated to improve its plasticity, and then the carbon black and various rubber additives and rubber can be evenly mixed into a rubber compound through mixing, and the rubber compound can be extruded. The blank is formed into a certain shape and then combined with the calendered or glued textile material (or metal material) to form a semi-finished product. Finally, after vulcanization, the plastic semi-finished product is made into a highly elastic final product.
We have summarized the following points when purchasing a water-blocking airbag
First look, second touch, and third try
The first look is to look at the surface of the airbag. Generally speaking, the surface of a good water-blocking airbag should be relatively Slightly rough and even, the surface is smooth and has no obvious unevenness.
The second touch is to feel whether the surface elasticity of the air bag is slightly rough and flat, whether there are sharp protrusions, and whether it is firm and powerful when pressed.
The third test is an inflation test at the highest rated pressure of the air bag. Inflate the air bag in the open state. Use soapy water to check whether there is any air leakage in the air bag. Observe whether the air bag has air leakage at a distant distance under the rated pressure. bursting phenomenon.
