Lampe Pipe Plugs

Seals a Range | No Bracing | Easy to Handle | Seals all Pipe Profiles | Repairable

A primary advantage of using a Lampe pipe plug over a comparable mini plug is the range each Lampe plug covers. Some mini plugs are designed for only one pipe size, but every Lampe pipe plug covers multiple pipe sizes - for example, the Type 1-600 is applicable from 8" all the way up to 24" pipe diameters.

The Lampe pipe plug does not need braced against linear movement for most applications. The engineering of how the Lampe seals to the pipe wall ensures that it fixes to the pipe securely as soon as 0.1 psi of air pressure is inside of the Lampe pipe plug. And should a puncture occur, the Lampe plug does not shoot out of place because the material is not stretched to achieve the blockage. It will soften as it loses air but remain secured long enough for the operators downstream to evacuate.

 Features

• No bracing against linear movement for most applications.

• No immediate deflation when punctured or loss of pressure because this special material does not stretch.

• Full circumferential and linear contact with pipe wall even at minimal pressure.

• When loss of pressure occurs, the plug will soften but remains in place for a longer time.

• Any accumulated water head will begin to drain slowly, while the back pressure does not force the plug out instantly.

All Lampe pipe plugs are lightweight, compact, and easy to handle for their respective pipe sizes. For example, when comparing the Type 1-600 Lampe plug to a conventional plug, which would both cover up to 24" pipe diameter, the difference in the size and shape of each unit is significant. The conventional plug weighs at least 25 lbs. and is over 3 feet in length with approx. 12inch in diameter - deflated.

In comparison, the Lampe Type 1-600 weighs only 9 lbs. and is about 4 feet in length - but only when laid out completely flat. It can be folded upon itself 2 or 3 times into a much smaller package. The Lampe pipe plug more closely resembles a piece of fabric in that the material is flexible until filled with air.

Lampe plugs can be ordered for up to 15ft of back pressure (Type 1), or up to 30ft of back pressure (Type 2). Flow through plugs are also available, as well as plugs with special sealing.

Lampe pipe plugs come in 2 different variants: Basic, for round pipe profiles, and Special Sealing, which provides an absolutely tight seal around the pipe. A Lampe with Special Sealing can adapt to and seal any pipe profile or shape.

Features

• Made of pure CR (Neoprene).
• No plasticizers used, thus no embrittling like most conventional rubber pipe plugs or bladders.
• Repairable.
• Inflated with 1bar (14.5psi).
• If punctured – the plug does not deflate rapidly or shoot through the line.
• Applicable to seal all pipe profiles.
• Adapts to and seals pipe profiles with an egg, kite, mouth, rectangular shape, or any other pipe profile.
• The Special Sealing provides absolute tightness.
• No bracing required.
• Material adjusts itself to the pipe wall during inflation.
• Proven work life of up to 40 years.

The rubber material of the Lampe pipe plug is unlike that found in conventional mini plugs. This rubber is cold vulcanized out of a 100% pure CR (Neoprene) coated material. There is no mixing in of foreign materials or substances which could weaken the rubber over time. Traditional mini plugs are made of hot-vulcanized synthetic rubbers with mixtures added.
