FRP TYPE # 240 ROLL-ON SHIELDS & TYPE # 180 SADDLES

Glas Mesh FRP Shields and Saddles are non-conductive, pre-shaped 240º or 180º peripheral snap-on pipes, fabricated from a hand laid up ultra-violet protected, salt tolerant, fiberglass reinforced vinylester resin. Pre-selected reinforcements are laminated over specially modified molds to a uniform thickness. Sub-zero temperatures will not affect properties.
  • 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.


FRP TYPE # 120 SPACERS

An extremely strong, 120 degree, non-conductive fiberglass reinforced plastic insulation spacer.
  • Used by utilities to prevent and/or correct electrical shorts caused when buried steel mains contact each other or are in close proximity.
  • The 120 degree 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

Use with: EPOXY SEAM SEALER, MOLDABLE SEALANT or PETROLATUM TAPE

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 # 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

FRP FLATTIES are made of a select combination of random glass mat reinforcements saturated with polyester resins combined with suitable fillers. These composites are cured and compressed under moderate pressure to form smooth dense laminates. FLATTIES tolerate point loading and are resistant to cold flow. They will not become brittle at cold temperatures. Available in 12" by 12" squares or economical larger sheets. We will be glad to quote prices on specific thicknesses or non-standard sizes, thicknesses or widths.

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.


FRP CASING INSULATOR TYPE # 220-240

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.


OTHER PRODUCTS

EPI-SEAL SEAM SEALER

Epi-Seal Seam Sealer is a two component, fiberglass reinforced epoxy resin system for high efficiency repairs on all riveted, bolted or welded tank or vat seams. Ideal for quickly repairing and making servicable a wide variety of leaking tanks, vats or drums. Available off the shelf in 1 lb. or 2 lb. kit sizes. Can be supplied in bulk.

Advantages:

  • Seals leaking seams and rivets or bolts permanently.
  • Unaffected by fuel and crude oil, kerosene, gasoline, furnace oil, alkalides and mild acids.
  • Extremely tough, yet "gives" with tank expansion and contraction.
  • Excellent adhesion to clean, or sandblasted steel surfaces.
  • Easy to mix and apply.
  • Will not drip or sag on vertical or overhead surfaces.
  • Cure can be accelerated by application of heat.

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

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.


COATED U-BOLTS

The U-BOLT-COTE is a seamless, vulcanized, polyolefin material that can be applied to all types of u-bolts and eliminates metal-to-metal contact. It provides a high abrasive and corrosive resistance on a continuous sheath, eliminating fraying and unraveling. It comes in a variety of sizes and can easily be applied to all makes and sizes of u-bolts.
  • 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.
