Modular system to assemble insulator rings, which allows spacers to be used on a wide pipe diameter range therefore reducing inventory costs. Spacers are quickly and easily assembled by manually fitting elements one into the other. The tooth insertion method allows on site adjustments to fit a wide range of pipe diameters. Spacers are manufactured entirely out of high density polyethylene (HDPE). No metal bolts or attachments are required. A low friction coefficient guarantees an easy insertion into the casing. Designed and tested to maintain continuous and long term support for the carrier pipe and its contents. Spacers provide a constant projection around the entire circumference of the carrier pipe. Spacers provide long term protection from corrosion. Spacers can be installed on steel-coated pipes, concrete pipes, ductile iron pipes or plastic pipes. Heights 25 mm and 41 mm homologated according to SNAM RETE GAS specification (GASD A 09.01.06 and GASD C 09.06.00). Available also in a special reinforced version for heavy duty applications (e.g. long crossings and/or big diameters). Tightening by tool type B75 for height up to 75 mm, tool type B130 for height from 90 up to 130mm.

Raci Spacers India Private Limited

Raci India was established in 2009 as a subsidiary of Raci SRL Italy to provide quality engineering solutions for the installation of oil and gas pipelines. Due to the sheer market's proximity to India, we began servicing the Middle East market in 2011.
In 2018, Flowheel FZE, the Middle East arm of RACI Pipeline Division of Raci SRL, Italy, began operations from Ras Al Khaimah Free Zone in the United Arab Emirates.
RACI has a significant presence in Iraq, Kuwait, Saudi Arabia, the UAE, Qatar, Bahrain, and Oman.
We work in both the water and oil and gas industries. Since 2018, Flowheel has been expanding its RACI business by entering into new partnerships and carving out a niche in the market from its Middle Eastern base.
In 2020, Flowheel and RACI India collaborated with Radlinger Primus Line Gmbh, Germany, to provide trenchless rehabilitation of underground pipelines in critical installations.
