PIPE
FRP Pipe is manufactured using filament winding technology and premium epoxy resin system, delivering superior strength, corrosion resistance and long service life for the most demanding industrial applications.
Product overview
Engineered for corrosive and demanding fluid services.
FRP pipe is manufactured by filament winding techniques that provide high strength and consistent fiberglass orientation. The system is designed for general industrial service, wastewater, fire protection, chemical processing, transmission lines and offshore platforms.
Compared with conventional metallic piping, Thai Composites offers excellent resistance to internal and external corrosion while reducing handling, installation and maintenance requirements.
Key performance characteristics
Built for long-term performance.
Each benefit is derived from the fiberglass-reinforced epoxy structure, corrosion-resistant liner and controlled filament winding process.
Strength & Durability
Constructed with 60–70% E-Glass roving using a cross-wound manufacturing process, offering excellent tensile strength.
High Chemical Resistance
The liner layer is manufactured using C-Glass and resin (≥70%), providing long-term resistance to acids, alkalis, industrial chemicals.
Corrosion Resistant
Will not rust, requires no protective painting, and prevents scale buildup, significantly reducing maintenance costs throughout its service life.
UV Resistant
The outer coating is made from PU or Resin-Rich Surfacing Veil, providing protection against UV radiation and harsh outdoor weather conditions.
Easy & Quick Assembly
Can be joined using epoxy adhesive, wrap joints, flanges, or O-ring connections, reducing installation time and labor requirements.
Light Weight
Up to 4–5 times lighter than steel pipes, reducing transportation and installation costs while eliminating the need for large cranes.
Pipe construction
Three functional layers. One complete system.
The pipe wall is engineered so each layer performs a specific role—from fluid contact and chemical protection to pressure resistance and weathering durability.
Filament winding
Controlled fiber orientation for optimum performance.
Automated winding, curing, demolding and cutting help ensure consistent fiber placement, product quality and dimensional accuracy.

Automated winding, curing, demolding and cutting help ensure consistent fiber placement, product quality and dimensional accuracy.
Bonded with two-component epoxy adhesive for accurate alignment and a smooth internal transition.
Connects GRE piping to valves, equipment and metallic flanges. ANSI, DIN and JIS options are available.
Mechanical joint designed to resist internal pressure and axial tension, ideal for buried pipelines.
Provides serviceable connections or site-fabricated laminated joints for complex piping layouts.
Joining systems
Flexible connection options for every site condition.
FRP pipes and fittings can be joined by adhesive, flange, mechanical lock, coupling or wrapped-joint methods depending on installation and maintenance requirements.
Compliance & Standards
Our pipe are designed and tested in accordance with internationally recognized standards to ensure the highest level of safety, quality, and reliability in every installation.

Chemical Resistance Test
According to the ASTM D3567 standard, a test specimen is outside diameter or inside diameter, thickness and length. Outside diameter: measure the outside diameter at both end pipe of each it and report the result of experiment. Thickness: measure the thickness of pipe at various point follow the direction of circumference at least 4 values and report the result of experiment both minimum and average values. Length: measure the length of pipe at 2 points that opposite together and report the result of experiment.
Test method is carried out in reference to ASTM D 2412 standard. A specimen with its longitudinal axis parallel to the plate is located in the testing machine. After applying the force to the desired deflection, the load is recorded. The force is continuingly applied until the specimen breaks and the ultimate compressive strength value is recorded. Due to the memory capability, pipe display excellent capability to retain its shape after the removal of the load.
The pipe and fitting shall be test 1.5 time of design pressure before delivery. According to ASTM D1599 and ASTM D2992 standards, a pipe specimen is attached to the end closures and filled with water. The pressure level is increased by using a pressuring device until the specific test pressure has been reached. The test pressure is ranging from 2 bars for non-pressure pipe to 50 bars for reverse osmosis membrane housing pipe.
According to the ASTM D2290 standard, a test specimen is loaded in the split disk test fixture which is applied tensile stress to the test ring. A hoop tensile strength is obtained after the ultimate loads are reached.
According to the ASTM D 638 and ASTM D2105 standard, a grooved pipe or dumb bell specimen is aligned and attached to the universal machine. The specimen is pulled at the specific speed and the ultimate strength is recorded.
To determine chemical resistant properties of the pipe in a deflected condition, a specimen is placed in the strain-corrosion test apparatus. After initial strain has been applied to the specimen, add the test solution and leave the specimen for 100 hours and 1000 hours. (ASTM D3681).
