Questions
Frequently Asked Questions
For any questions not covered, please do not hesitate to reach out to our team.
What is the difference between HDPE and Polypropylene (PP), and how do I know which one to specify?
HDPE offers superior impact resistance, low-temperature toughness, and flexibility, making it ideal for buried fluid piping, liners, and abrasion-prone slurry transport. Polypropylene provides higher rigidity, better performance at elevated temperatures (up to ~80–100°C depending on grade), and greater resistance to concentrated acids, bases, and aggressive organic solvents. Our engineering team evaluates your process chemistry, operating temperatures, and structural loads to recommend the optimal resin grade.
Can HDPE and PP sheets or pipes be welded or fused directly to each other?
No. Because HDPE (high-density polyethylene) and PP (polypropylene) have distinct polymer backbones, molecular weights, and melting points, they cannot be reliably thermal-welded together. Transitions between the two materials are engineered mechanically using flanged connections, threaded transition fittings, or custom mechanical couplings.
Do you provide custom fabrication or only supply standard sheet and pipe dimensions?
While we supply standard raw materials, our core focus is end-to-end engineering and custom fabrication. This includes CNC cutting, thermoforming, butt fusion, extrusion welding, and electrofusion for custom chemical tanks, vessel liners, ducting, manifolds, and dual-containment spool pieces tailored to CAD specifications.
Can thermoplastic piping and sheets replace traditional steel or concrete?
Yes, particularly in corrosive, abrasive, or weight-sensitive environments. Thermoplastics eliminate rust, scale buildup, and chemical degradation without requiring expensive secondary coatings. Additionally, they reduce transport and rigging weight while providing smooth internal bore surfaces that reduce pump head loss and resist scaling.
