PSI provides for each combination of protective and carrier pipe the best spacer with matching casing end seal. Screwless spacers are available as well as the classic screw version for various loads Casing Spacers & Casing End Seals supplier in Saudi Arab
Casing Spacers are used to center water, sewer, gas and other fluids in casings; casing insulators are used to support and electrically insulate a cathodically protected pipeline from a casing pipe through which it must pass. We provide each in a number of common sizes as well as end seals to accommodate any combination of pipe sizes. These products are virtually corrosion proof and provide insulating protection from a possible electrical shorting between the carrier pipe and casing.
With excellent dielectric resistance and low moisture absorption for minimal electric current loss and no impairment of cathodic protection, polyethylene spacers and insulators are an economical choice for use on all plastic pipe & metal pipe up to 48' in diameter and smaller ductile pipe.
Polyethylene casing spacers and insulators are manufactured by injection molding using polyethylene, which provides high impact strength and a low coefficient of friction. Runner height for polyethylene spacers can be increased to provide clearance for bell and spigot connections, with a standard runner height from 25mm to 55mm.
Polyethylene casing insulators are available from 1" through 48" , recommended for every 6 to 8 feet of pipeline. Molded into the inner surface of the casing insulators are grooves which prevent slippage of any carrier pipe coating.
Casing Spacers require no special tools, no grease is used, and only a screw driver for installation, and they are easily bolted on by a single worker. They eliminate the need to fill the casing annulus with sand, grout or pea gravel which acts as an electrolyte and can introduce unwanted current to the steel or ductile iron. Abrasion resistant dielectric runners prevent damage as the carrier pipe is being installed in the casing and, along with the dielectric inner liner, provide optimum insulation.
