Reli Sleeve - Pipe Sleeve / Insert Sleeve

They are used for internal fittings welded pipes and internally coated accessories. Which provide a protective barrier lining during application of welding, ensuring the integrity of the coating (burns) and avoiding the generation of localized spots of corrosion at the joints.


"Currently the most effective means of welded pipes with internal coating for the SLEEVE BOARD is a coated metal connection system for bonding, continuity and internal corrosion protection coating on the pipe welding process."

The sleeve Board relates to the field of connections for coupling and welding lines internally coated carbon steel for transporting petroleum products and other fluids.

In the oil industry, as well as in various other industrial sectors that store, transport and distribute products through pipelines and / or arrangements of piping products and systems are developed to streamline the features in the area of materials, specifically in the prevention and corrosion resistance.

So many have come to market systems corrosion protection and one of the most efficient pipeline is coated internally by various types of products such as: thermoplastic, polyethylene and cements to name a few. In this type of coating system it is necessary to protect the integrity of the coating and to continue this in the action of welding two pipes coated with said through an internal connection designed for this purpose, as represented by the SLEEVE BOARD

The SLEEVE BOARD is designed to prevent turbulent flows, and this decreases the coefficient of abrasion and corrosion and sediment accumulation that could create areas of corrosion, thanks to the bezel present at the ends of it, allowing the free flow of fluid .

The Board hose connection is a system to protect the integrity of the coating and to continue this in the process of welding two pipes with internal coating.
• Fast assembly.
• It applies to pipes offshore / onshore plant and pipelines.
• Compatible with all resins.
• Antifouling coating 100%
• Waterproof, prevents scale, high resistance to corrosion and abrasion, no toxicity.
• Temperature: -5 ° C to 145 ° C


Two component system (Epoxy short gel time and high thixotropy) used in the installation of Slevees, which guarantees the hydraulic seal in the pipe joints. Advantages:

• Short gel time and high thixotropy,
• Easy application and handling in the field
Spray application system and Cartridges:

• Easy handling
• A controlled mixing of the components is ensured
• It reduces waste product
• The risk of contamination is minimized


Prefabricated accessories - Standard
They are regular fixtures (Elbows, Semicodos, Tees, Flanges, reductions) with welded ends and internally coated plant, which allow the installation of Slevees for welded joints with pipe extensions.

• Welding process: Semi Automatic Ground and certificate
• Standards: API 1104 or ASME Section IX
• Diameter : 2 "- 48"
• SCH 10 -160


• Quick and easy field installation
• Lower installation costs
• Special coatings


They are applied to change substrate properties (corrosion resistance, abrasion, adhesion, conductivity, etc.) materials Technologies:

Liquids Epoxy Phenolic - Epoxy Urethanes
Powder FBE (fusion bonded epoxy) - Fluoro polymers - Nylon
Others Ceramic, Chemical deposition

Important factors in the application of coatings:
• Surface Preparation
• Application controlled conditions (% RH, ° T)



• It is providing constant protection against corrosion and abrasion caused by the fluid through a uniform physical barrier.
• Prevents corrosion of the material throughout the cycle, storage, commissioning, operation and stops.
• Increases the production rate.
• Control of deposition of paraffins, asphaltenes and fouling materials.
• Improved hydraulic system efficiency (reduction of friction coefficient) thus increasing the transport capacity of the system fluid.
• Lower production costs by pumping (investment pays for itself in less than three years).
• Reduced maintenance costs (pigging and inhibitors).


• It represents lower investment costs compared with steel alloys greater

Alloy Steel Cost driver
Naked Carbon Steel 100 % (base Cost)
Carbon Steel Lining 150 %
Stainless Steel 316L 600 %
Stainless Steel 904L 900 %
Inconel 625 1800 %
Inconel 825 2200 %


• You can use pipes and fittings smaller thicknesses (Schedules), since it is not necessary to design with safety margins lost by corrosion.
• It facilitates inspection and commissioning.
• Extends the life of the material.
• Different coatings for different applications and operating conditions.
• Quick return on investment.


So what is the FBE

It is an epoxy powder coating adhesion by fusion (Fusion Bonded Epoxy - FBE)., industry standard, environmentally safe, heat-stable, and widely used as corrosion protection of pipe and fittings
system FBE coating consists of applying a resin termodirigída, applied in thicknesses of 400 -. 600 microns on the surface
Epoy The film exhibits an extremely hard and smooth surface with excellent adhesion to the steel surface, excellent chemical resistance, high strength the efforts of the terrain making it a lasting and reliable coating.


The FBE anticorrosion coating is widely used for the protection of pipes, fittings and equipment steel transmission and distribution networks of the oil products sector.
Likewise it has wide application in other sectors such as mining, agribusiness, construction, etc.


Advantages of Using Internal Coatings FUSION BONDED EPOXY (FBE)
• Durability and high performance under different conditions (proven over 50 years)
• It works perfectly with cathodic protection systems
• Film with high density of links (high cross-linked film)
• High impact resistance
• High abrasion resistance
• High flexibility
• Short times of application and curing
• Environmentally friendly (does not contain VOC)
