Quality is key: kwik-ZIP Australian manufacturer Kwik-ZIP is supplying a wide range of industry sectors with high-quality centraliser and spacer systems from across its range of products. and the curved bow spring design of the HD30 model ensured that the carrier pipe would easily ride over any protrusions. “The Kwik-Zip spacers were a great solution for slip-lining, alleviating the risk of potential damage to the PE pipe during the process,” says Jo McAnulty, the site engineer for this project.
HDX/HDXT series The HDX and HDXT series spacers are designed for use on medium to heavy weight pipes in cased crossings. They can be utilised on a wide range of pipe material including steel DICL, HDPE, Concrete and MSCL carrier pipes, minimising running friction between the carrier pipe and the casing during installation. The HDX casing spacer comes in four runner heights, 38mm, 65mm, 90mm and 125mm. The HDXT casing spacer also comes in four runner heights, 43mm, 63mm, 103mm and 153mm. The different runner heights across the two models ensures that

anufactured from high grade thermoplastic, kwik-ZIP products are used and recommended by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms. The use of kwik-ZIP products helps contractors to comply with the numerous regulations that require casing centralizers or pipe spacers (slippers or spiders), including wastewater and sewerage codes and well construction standards. Since its inception in 2000, the company has been designing centralisers and spacers systems for a wide range of applications across many different industry sectors. With warehouse facilities in the UK, Sydney and Texas, the company also has established stockists in Australia, the US, the UK and New Zealand markets. “They are recommended, specified and used by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms across the world,” says Paul Jeffreys, Australian Business Manager for Kwik-Zip. Kwik-ZIP is also the only Australian company providing simple, cost-effective, and high-quality solutions, and the HD and HDX/HDXT spacer system series align with this ethos.

“They are recommended, specified and used by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms across the world.” The HD and HDX/HDXT spacer system series are lead and metal-free, non-corrosive, chemical and oil resistant, and suitable for use on all pipe materials (including Steel, DICL, HDPE, Concrete and MSCL). They also have a quick and easy installation process, reduce point loading via a unique load sharing runner system, and minimise damaging vibration and movement transfer from outer casing to carrier pipe via suspension and dampening effect.
HD series The HD series has designed for trenchless and cased crossings, slip lining, gravel packed well screens, pump torque arrestor, water well casing, coal seam methane casing, pump riser/ submersible pump installation, and piling. They come in four sizes, ranging from a 30mm bow up to a 100mm bow, and can be used for both vertical and horizontal applications. Kwik-ZIP® HD-30 spacers were installed recently into the abandoned DN330 ST Gas Mains to facilitate the slip-lining of DN125 PE Water Main.
