Compatible with all types of pipe material, kwik-ZIP’s HD and HDX/HDXT spacer system series can be used on and in corrugated pipe installations.
Manufactured from high-grade thermoplastic, kwik-ZIP’s casing spacer and centraliser products are used across the industry, by pipeline and civil contractors, water and gas utilities, drilling companies and international engineering firms.
The HDX and HDXT spacer system series are aligned with the kwik-ZIP ethos to provide simple, cost-effective, and high-quality solutions.
Manufactured and designed to be utilised on and in many types of pipe, including corrugated installations, the HDX and HDXT spacers are among the most versatile and adaptable on the market.
The use of kwik-ZIP products helps contractors to comply with the numerous regulations that require casing centralisers or pipe spacers (slippers or spiders), including wastewater and sewerage codes as well as well construction standards.
Since its inception in 2000, kwik-ZIP has been designing centralisers and spacers systems for a wide range of applications across many different industry sectors. Available in various product series (HDXT, HDX, HD, GT, 380, and 155), each is accessible with varying bow/runner heights, making these highly flexible products.
An adaptable approach
kwik-ZIP’s HDX and HDXT products are suitable for installation on and in corrugated pipe that is being inserted into a smooth pipe, and function on a smooth pipe that’s then being inserted into a corrugated pipe.
For corrugated carrier pipe, the flat base of the HDXT and HDX runners bridge the pitch of the ridges, which allows the load to be transferred to the carrier pipe via the full length of the runners. And if the enveloper is corrugated, the HDX and HDXT flat-wear pads allow for smooth slip lining along the invert.
It’s these types of innovative approaches that make kwik-ZIP’s the first choice for many when looking for a versatile spacer solution.
Products in the HD series are 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.
Coming in four sizes that range from a 30mm bow up to a 100mm bow, the HD series can be used for vertical and horizontal applications. With unique features such as a curved bow spring that boasts a superior centralising force, no special tools are required to assemble the HD Series casing spacers.
Similarly, kwik-ZIP’s 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 material, including steel, ductile iron pipe (DICL), high-density polyethylene (HDPE), concrete and mild steel cement lined (MSCL) carrier pipes, minimising running friction during installation.
The HDX casing spacer comes runner heights 38mm, 65mm, 90mm and 125mm, while the HDXT comes in runner heights of 43mm, 63mm, 103mm and 153mm.
The different heights across the two models helps to ensure that pipeline installers can handle a broad range of carrier pipe outer diameter (OD) and casing inner diameter (ID) combinations and customise pipe position for grade control or ‘centring’.
The fact the casing spacers are compatible with all types of material stations the pipe to promote even grout cover. In the event the pipe is not to be grouted, the HDX and HDXT spacers support and isolate the carrier pipe and its contents for the design life of the installation.
This highlights kwik-ZIP’s ability to provide an off-the-shelf solution irrespective of the requirements due to its wide range of products and options.
The HD, HDX and HDXT are certified against the Water Services Association of Australia (WSAA) Product Spec # 324 – Casing Spacers and all other models are designed to meet these requirements. kwik-ZIP products are also approved and listed on the Accepted Infrastructure Products and Materials (IPAM) list for the Southeast Queensland Water Supply and Sewerage Design and Construction Code (SEQ Code).
kwik-ZIP maintains a focus on price effectiveness, simplicity and rapid on-site assembly to ensure that its centraliser and casing spacer systems deliver significant cost, time and operational advantages.
