kwik-ZIP gets the show on the road

In early 2022, kwik-ZIP HDXT-43 spacers were used to complete a project for Highways England near Birmingham Airport, where they provided an effi cient and seamless solution for bunding together HDPE pipe.

The kwik-ZIP HDXT Series is an anticorrosion, non-metallic casing spacer range for pipe-in-pipe (PIP) applications such as slip lining and cased crossings.

Suitable for heavy-weight pipe materials including steel, ductile, mild steel cement lined (MSCL), glass reinforced epoxy (GRE), polyvinyl chloride (PVC) and high-density polyethylene (HDPE), it can be used on all diameters from 300 mm and beyond through the simple addition of multiple segments.

Kwik-ZIP HDXT-43 spacers were recently used on a project for Highways England on a M42 J6 diversion in Birmingham. UK-based infrastructure services and engineering company Amey used the spacers to facilitate the slip-lining of a four-pipe bundle.

Junction 6 of the M42 connects the M42 motorway to the A45 to the east of Birmingham, where road users su ered signi cant delays and due to capacity constraints. e M42 J6 Diversion Project was designed to alleviate some of these delays experienced by motorists. e 4-pipe bundle consisted of 2 x DN 180 HDPE and 2 x DN450 HDPE pipes with a run length of 135 m. Kwik-Zip spacers were selected for this project due to their ability to secure the 4-pipe bundle together; their suitability to work with any pipe pro le; and their design that protects and supports the bundle during the sliplining process.

Kwik-ZIP’s large range of spacers caters for a wide range of carrier and casing pipe size combinations, as well as providing exibility to deal with project alterations. Kwik-ZIP spacers have no metal parts and are made from Kwik-ZIP’s engineered thermoplastic blend that is exible, extremely tough and has a low coe cient of friction.

Amey site manager on the M42 J6 Diversion Project Tim Loho commended kwik-ZIP for the intuitive design and ease of use of the spacers, which helped the project to come to fruition.

“ e spacer system was easily installed and was an excellent aid in slip lining the 4-pipe bundle through the tunnel, which we had installed prior to slip lining works – a truly excellent product,” says Loho .
