Novel thin-walled thermoplastic or thermoset pipes of at most 5 millimeters in thickness which can withstand a varied range of internally generated andor applied pressures up to at least 5 bars, preferably at least 20 bars, for utilization within, primarily, liquid transport systems. The result of the operation is randomized while the computational cost becomes as much as that without randomization. Other embodiments of the invention are directed toward heat management, and other process enhancements for making the system especially efficient. The method comprises embossing and pressing in a single step a monolayer mat comprising wood particles having an average size of less than 4 mm and a resin, so as to obtain an embossed monolayer particleboard siding.
