What should you look out for when using compressed air couplings and safety quick-release couplings for sewer repair?

The refurbishment and repair of leaks and broken pipes in house connections and sewer pipes using inliners, short liners or cross liners must be done quickly and professionally. You should therefore opt for premium safety couplings from STEINCONNECTOR.

When installing inliners, short liners or cross liners in the refurbishment of sewers or house connection pipes, speed is often of the essence. The short curing time of the two-component resins calls for rapid, uninterrupted work.

When choosing the compressed air coupling, you should therefore pay close attention to safety. STEINCONNECTOR compressed air safety couplings either have an additional lock nut that prevents inadvertent uncoupling or a special release bushing that can only be opened by turning it manually to a special position. These two safety systems prevent inadvertent uncoupling of the compressed air couplings.

Another common issue is a lack of space, especially when it comes to house connection pipes. If the inliner is pushed to the leak location with the help of a packer and push rods, the compressed air coupling should take up as little space as possible. That’s why all compressed air safety couplings from STEINCONNECTOR are designed to be small and compact.

Which types of compressed air couplings and quick-release fasteners do we recommend for use in sewer and pipe refurbishment?

The STEINCONNECTOR compressed air coupling range offers you five coupling series that are perfect for use in refurbishment work on sewer pipes and house connection pipes. The 090, 100, 126, 160 and 161 series have been specially developed for sewer technology, and sewer refurbishment contractors around the world have been relying on them for many years when repairing sewer and house connection pipes.

Which connection types for compressed air couplings and quick-release couplings are offered in the STEINCONNECTOR coupling range?

Various factors matter when choosing the coupling connection. The choice of the right coupling depends, among other things, on whether the compressed air connection has to be connected to inliners, repair packers, sealing bladders, pipe sealing bags or sewer sealing stoppers. The STEINCONECTOR coupling range offers compressed air quick-release couplings with pinch bushing, hose bushing, female thread and male thread.

What safety requirements apply to the hose connections of compressed air lines in sewer pipe and house connection pipe refurbishment?

In addition to the versatile compressed air couplings and compressed air quick-release couplings, the STEINCONNECTOR range of compressed air technology includes compressed air accessories such as pinch, crimp or compression bushings for the hose connections. Particular attention should be paid to safety when it comes to compressed air hose connections in sewer work.

In addition to the common hose bushings, STEINCONNECTOR also offers special pinch bushings that create a form-fitting connection instead of a simple friction-locking connection. The pinch bushings are matched to the hose bushings and can therefore be perfectly combined.

The technology comes from hydraulics and offers more security due to the additional form-fitting connection. The friction-locking and form-fitting pinch bushings are perfect for compressed air hoses that are used in sewer technology. Compressed air hoses used for pipe and sewer pipe repair are often exposed to high tensile forces.

The form-fitting STEINCONNECTOR compression bushings or sleeves are compatible with the coupling series 160 and 161 and are perfect for use in the refurbishment of sewer and house connection pipes, where they offer additional safety.
