What Is Pipe Plug and How Does It Work?

Many storm drainage-pipelines, sanitary sewer lines and low-pressure underground pipelines do not have valves or spectacle flanges to block fluid flow in the line. PlugCo has the answer to this dilemma with its pipe plug product range! By easily blocking these lines and permitting access to them without the need for expensive, maintenance-intensive valves and flanges! So that the pipeline becomes accessible for inspection, maintenance or modification.

PlugCo’s extensive range of pipe sealing and pipe repair products includes many designs of inflatable stoppers, joint testers and pillow packers.

Product Range

PlugCo produces inflatable pipe plugs in sizes from 35mm (1.4 inches) to 3600mm (142 inches) in diameter. The designs of these plugs fit into 3 broad categories – cylindrical single-size plugs; cylindrical multi-size plugs; and conical plugs.

A conical pipe plug, although more expensive, has several advantages over a cylindrical plug design. Conical pipe plugs are manufactured in larger sizes than cylindrical plugs – up to 3600mm (144in / 12ft) in diameter. The most significant difference between the two designs, however, is that a conical pipe plug can be folded to a small diameter which can be easily inserted into a narrow or constricted opening. Therefore, in many cases, this advantage means that a manhole cover need not be removed or to be located near the location where a conical plug is to be inserted or inflated.

In addition to its extensive product line of pipe plugs and conical plugs, PlugCo has products to test individual pipe joints. By testing a single pipe joint only, these joint testers have low water consumption. In other words, this means lower testing costs and reduced environmental impact.

Additionally, we produce flexible pipe packers for point repairs of sewer, drainage and water lines. These products provide a no-dig, trenchless solution for pipe repairing that will be attractive to both utilities and contractors. Straight or lateral packers are for straight lines repairing, and ‘bendy’ packers for repairing 45 and 90 degree elbows. PlugCo also provides pillow packers for point repair of large pipe sizes. Pillow packers, like the conical pipe plugs, can easily fit through narrow or constricted openings.

Special Products

Moreover, we have developed and manufactured a special stainless-steel plug for Cured-In-Place Pipe (CIPP) repairs. This plug uses process steam to accelerate the curing process and the SS construction is significantly different from other CIPP plugs in the marketplace.

Although PlugCo mainly serves the ‘water infrastructure’ industry – sewer, storm drains, and potable water pipelines, the sealing of hydrocarbon lines such as oil, petrol and natural gas is also within PlugCo’s scope. Our nitrile rubber gas plugs provide excellent resistance against petrochemical fluids. PlugCo produces gas plugs capable of withstanding up to 8 bar pressure for Pig applications in oil and gas lines.
