• Used by utilities for electrical isolation and abrasion control of mains and by industry for load distribution, energy conservation, and insulation protection at hangers and supports of over head and pylon-supported pipe mains.
• Employed for abrasion control on plastic pipe systems and wrapped cables.
• Substitute for, or use in place of metal saddles where electrical insulation is desirable.
• Ideal for pipes exposed to corrosive environments.
• Protects pipe insulation and plastic pipe systems from abrasive wear at overhead hangers and supports.
• May be banded, cemented or taped into place.
• Special lengths can be made available.
• Oversized shields and saddles are used over bridge mains that have had protective tape applied, resulting in an increased outside diameter of the pipe and without damaging the tape.

• Used by utilities to prevent and/or correct electrical shorts caused when buried steel mains contact each other or are in close proximity.
• The 120º peripheral circumference minimizes any possible shielding effect on the pipes’ cathodic protection systems.
• For most applications FRP Spacers offer superior physical properties over other plastics and rubber such as PVC and polyethylene.
• The superior compressive strength of FRP over other non-conductive materials is necessary due to the point loading nature of contact shorts.
• FRP spacers will not cold flow, will not become brittle in cold temperatures and will not soften or distort from heat.

FRP TYPE # 60 SPACERS used with Epoxy Seam Sealer is a cost effective, long term solution to above grade crevice corrosion. The Seam Sealer is used to bond and seal the inside surface of the FRP Spacer to the corresponding pipe surface. Once in place the FRP Spacer provides protection on just that small inaccessible section of pipe that needs it most. It is extremely important to use fiberglass reinforced plastic because its high compressive strength enable it to tolerate the point loading that would cause a non-reinforced plastic material to cold flow and fail.

The FRP Spacers can also be used with Moldable Sealant and Petrolatum Tape when conditions prevent the use of Epoxy Seam Sealer.

FRP FLATTIES have numerous applications in the natural gas distribution and transmission and liquid pipeline industries.

• They eliminate or correct above or below ground metal-to-metal electrical contacts, particularly on underground steel mains.
• Custom fitting as non-corrosive, non-conductive spacers or shims.
• A standard product for spacing, isolating or protecting pipes and valves from their supports.
• Idea protection for coated tank bottoms.

The two pieces, one 220º insulator and one 240º insulator, snap together surrounding the carrier pipe and separating it from the casing. No tools, banding or welding are required. 

Available in special lengths.

Ideal for retrofits where the original or existing spacer or insulator has been damaged, deteriorated or failed.

The materials are generally used over 40-50 mil factory applied coatings, but are applicable to any field or factory installed coatings for new construction and for retrofits.

• Maintain same support strength of pipe hanger system.

• Eliminate chafing and rusting pipe caused by iron rolls.

• Eliminate electrical grounding of the pipeline to the bridge.

• Eliminate insulating joints at each end of the bridge, and include the suspended line as part of the cathodically protected pipeline maintaining continuity of cathodic protection.

• Absorb vibration from traffic or other sources, saving wear and tear on pipe hanger parts.

Other than third party damage, crack growth is the most common type of polyethylene pipe failure. Shear installations and excessive bending due to external pessure are two potential causes of pipe failure.

Inadequate Support and/or protection wherever a PE pipe is inserted into an old steel or cast iron pipe, can over time develop point loading contact precisely where the plastic pipe enters and exits the metal main. Downward pressure from soil compaction may cause PE to cold flow and gradually develop a shear crack failure.

It has always been standard practice to protect inserted polyethylene services with a plastic split sleeve prior to backfilling. This type of precaution for the larger plastic mains will contribute to the long term integrity of the system. Glas Mesh FRP Type # 240 Shields and Type # 180 Saddles provide a superior means and material for protecting PE pipe at any insertion.

• It is excellent for eliminating corrosion problems on piping in refineries, chemical plants, paper mills, offshore platforms, rigs and the shipping industry.
• Virtually unaffected by heat, ultra-violet rays, vibration, electrolysis, sandblasting and any other rigors specific to industrial and marine environments.
• The U-BOLT-COTE is excellent for use on plastic, FRP or glass-lined pipe for shock absorption.
• The U-BOLT-COTE also will help reduce vibration and noise levels.
