Straightforward answers about our thermoplastic extrusions, chemical-resistant liners, and testing protocols.
Our high-density polyethylene liners resist continuous exposure to strong acids (e.g., sulfuric, hydrochloric), bases (e.g., sodium hydroxide), and a wide range of organic solvents. Each formulation is validated through accelerated immersion tests per ASTM D543 to confirm zero permeability and no measurable weight change after 30 days at elevated temperatures.
We run multi-axial stress evaluations combined with thermal degradation testing from -40°C to 150°C over 500 cycles. Dimensional changes are measured with laser micrometers at each interval. Our materials consistently stay within ±0.5% of original dimensions, ensuring reliable fit in pipeline joints and flanges.
Standard profiles ship within 10–15 business days after design approval. For complex multi-axial geometries or specialized liner thicknesses, allow 20–25 days. We provide a detailed timeline during the quoting phase, including material sourcing and tooling adjustments if needed.
Yes. Our technical team can assist with joint sealing procedures, thermal fusion parameters, and post-installation pressure testing. We also provide written installation guides that cover torque specifications, cure times for adhesives, and recommended inspection intervals.
Every production batch undergoes accelerated thermal aging at 120°C for 1,000 hours, followed by a hydrostatic pressure test at 1.5× the rated working pressure. Permeability is measured using a gravimetric method with a detection limit of 0.01 g/m²/day. Results are documented in a certificate of compliance shipped with each order.
Absolutely. We produce liners and extrusions to customer-supplied drawings or reverse-engineered measurements. Our quality system includes a dimensional report with tolerances of ±0.1 mm for critical sealing surfaces. Contact our engineering team with your specifications for a feasibility review.
These notes address specific interpretations and conditions that apply to our technical documentation, test reports, and product specifications. They are intended to prevent misunderstandings regarding performance claims and material properties.
Zero fluid permeability refers to the absence of measurable fluid transmission through the liner wall under the specific conditions of the multi-axial stress evaluation. This test is conducted at 25°C and 1 atm differential pressure using a standard hydrocarbon mixture. Permeability rates below 0.01 g/m²/day are reported as zero. Results may vary at elevated temperatures or under vacuum conditions.
Dimensional stability is defined as a change in length, width, or thickness of less than 0.5% after 1000 hours of exposure to the specified chemical environment at 60°C. Measurements are taken at three points along each extrusion. This definition applies only to profiles produced from our standard HDPE and PP formulations. Custom blends may have different tolerances.
This test simulates 20 years of thermal cycling by exposing samples to 500 cycles between -20°C and 120°C, with a 2-hour dwell at each extreme. Degradation is measured as a reduction in tensile strength or elongation at break exceeding 20% compared to unaged samples. The test does not account for simultaneous chemical exposure or UV radiation unless explicitly stated.
No. The multi-axial stress evaluations and permeability tests are performed on pipe liners with diameters between 50 mm and 300 mm. For diameters outside this range, additional validation is required. The test fixtures and stress profiles are calibrated for these specific dimensions, and results cannot be extrapolated without further testing.
Chemical resistance data is based on immersion tests at 23°C for 7 days using reagent-grade chemicals. Resistance is rated as "excellent" if weight gain is less than 1% and no visible cracking or swelling occurs. Ratings for mixtures, elevated temperatures, or prolonged exposure beyond 30 days are not covered by these standard tests. Always consult our technical team for application-specific recommendations.
These evaluations apply simultaneous tensile, compressive, and torsional loads to a pipe liner section using a custom-built test rig. The loads are derived from typical installation stresses, including bending, internal pressure, and thermal expansion. The test duration is 1000 hours at 50°C. Failure is defined as any visible crack, delamination, or leak. The test does not simulate cyclic fatigue beyond 1000 cycles unless otherwise specified.
Standard liners crack when pipelines shift or vibrate. Our HDPE formulation is tested under combined tensile, compressive, and torsional loads — no fluid migration even after 10,000 stress cycles at 85°C.
We run 1,000-hour thermal aging at 150°C in concentrated sulfuric acid vapor. Competitor materials lose 40% of tensile strength; ours retain 94%. That difference means a 15-year longer service interval.
Thermal expansion mismatch causes joint failures in chemical plants. Our extrusion process controls crystallinity to within ±1.2%, so flanges stay sealed and pipe sections remain aligned through seasonal temperature swings.
We modify the polymer backbone with proprietary stabilizers that resist swelling in chlorinated solvents and ketones. Third-party immersion tests per ASTM D543 show less than 0.3% weight change after 30 days in methylene chloride.
From a Gujarat chlor-alkali unit to a Maharashtra refinery, our liners have logged over 200,000 operating hours without a single permeability incident. Plant engineers cite the predictable failure mode — none — as the main reason they reorder.
