our Machine system
In-house filament winding and test equipment: split disk, UTM, pipe stiffness and hydrostatic verification.
Mechanical Properties (Split Disk Test)
Samples from each project is taken to be tested for both axial and circumferential (hoop) tensile strengths. The specimens are loaded-to-break point using UTM and split disk respectively for axial and hoop tensile strength
Mechanical Properties (UTM)
Tensile strength, maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material.
Mechanical Properties Pipe Stiffness
In this test following ASTM D2412, a pipe sample from each production batch is tested for stiffness. The specimen is deflected to a strain level and the crushing force is noted.
Hydrostatic Test
This is the hydraulic pressure tester specialized in GRP pipe which can test 4,000mm with max. pressure 15bar, and max. length 10m.
Our customers
Trusted by power, semiconductor, steel and chemical plant leaders across Korea, Vietnam and Japan.

Why FRP for Power Plants?
Steel corrodes. Rubber-lined steel delaminates. FRP/GRP composites give you the long service life and low total cost of ownership that 24/7 generation demands.
