A rubber plug that is used for bolt holes is an accessory that is smaller in size. Inflatable rubber pipe plugs or expandable rubber pipe plugs are made of reinforced rubber that fits in any type of application that your pipeline needs. They are used to perform leakage test on different pipelines. Testing rubber pipe plugs is used almost in every channel, including urban infrastructure. They can be used to seal pipes, sealing the pipes in industries, and in house connections. All the pipe plugs should be blocked adequately. Any kind of debris or contaminating material can damage the pipeline’s seal and results in rupturing of inflatable plugs. Pipe plugs rubber is the most flexible plugs, made up of rubber material and are available in the market. Steel rubber pipe plugs have a fine structure, and they are responsible for providing strength to the whole framework. These plugs have excellent corrosion resistant properties in a different type of applications. They have corrosion-resistant properties in almost all the mediums except for sulfuric acid, alkane and chromic acid. They also have wear-resistant properties. We know that rubber has high elasticity. Due to this property, it can absorb mechanical shock and absorb corrosion from powerful friction performance stirring. If we want to carry out a leakage test, we will use a rubber pipe plug in order to block the pipe from each end with the help of two pieces. Sewer pipe plugs are made up of natural rubber. They are available in different diameters. They are used whenever fast and reliable sealing is required. Manny pipe plugs are made up of chloroprene rubber. They have a very high resistance to chemicals. They come in a variety of sizes and shapes.
