Roll-On Shields are a fiberglass reinforced plastic, 240° circular, pre-shaped method of electrical isolation for suspended pipe mains.
 

• 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.

Glas Mesh FRP Saddles are non-conductive, pre-shaped 180° peripheral snap-on pipes, fabricated from a hand laid up ultra-violet protected, salt tolerant, fiberglass reinforced vinylester resin.


Type #30, 60, 90, 120 Spacers

FRP Type #30, 60, 90, and 120 spacers used with Epoxy Seam Sealer are a cost effective, long term solution to above grade crevice corrosion.

Localized Corrosion pitting (crevice corrosion) is a common problem on exposed steel pipes. Generally the most severe areas of corrosion occur precisely where the pipe contacts its support. This contact point is a natural collection site for moisture. Moisture plus poor drainage creates an ideal corrosive environment. Left unchecked, corrosive pitting will eventually require replacement of the affected pipe. Replacement is always many more times the cost of preventative or corrective maintenance.

FRP TYPE #30, #60 and #90 SPACERS used with Epoxy Seam Sealer are 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”

Flatties are made of a select combination of random glass mat reinforcements saturated with polyester resins combined with suitable fillers.

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.
• Ideal protection for coated tank bottoms.

Type #220-240 Casing Insulator

A tough, inexpensive, 2 piece casing insulator that electrically isolates a gas main carrier main from a steel casing. Provides excellent abrasion control.

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.

Coated U-Bolts

The Coated U-Bolt is a seamless, vulcanized, polyolefin material that can be applied to all types of u-bolts and eliminates metal-to-metal contact.

• 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.

 

Seam Sealer is used to bond and seal the inside surface of the FRP Spacer to the corresponding pipe surface.

Non-conductive Pipe Rollers

NON-CONDUCTIVE PIPE ROLLERS from LB&A. Inc.

Non-Conductive Rollers are used in lieu of FRP Shields with any thin barrier coating. The urethane based rollers are used as a direct replacement for cast iron rolls.

Non Conductive pipe rollers prevent the passing of current from the pipeline to bridge structure and rebars. As a direct replacement for cast iron roll, non-conductive pipe rollers are made of the highest specification polyurethane compound which is cast around an integral steel sleeve to form a full length bearing for the axle. They can be used in conjunction with the FRP Type # 240 Roll-On Shields™.
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.

FRP and Co-Polymer Half Rounds

Half Rounds minimize pipe to support surface contact which allows moisture to drain away from the bottom of the pipe at the point of contact.

Conduit Hangers

Includes: ¾″ Hot Dipped Galvanized Rods, Hex Nuts & Flat Washers, 2″ x ½″ FRP Flat Bar, 1″ FRP Round Tube, and if specified, 2″ x 2″ x ¼″ FRP Square Tube.
