Technology

Tite Liner® system (HDPE Lining), a technology that enables a thermoplastic liner to fit tightly inside a host pipe. The Tite Liner® system begins as a thermoplastic pipe liner that has a larger outside diameter than the inside diameter of the steel, compressed radially as it passes through the specially designed roller reduction box. The liner then expands tightly following installation. The tight-fitting liner acts as a continuous barrier between the host pipe and the corrosive or abrasive material. The Tite Liner® system comes in sizes from 50 mm to 1,300 mm (2 inches to 52 inches) in diameter, with larger diameters possible in certain situations.

Bondaliner™ is applied via a rotational lining process. The granulated powder resin fed inside the fitting or vessel which rotates in an oven on two perpendicular axes, giving the resin time to melt and spread uniformly over all interior surfaces of the equipment. This unique Bondaliner™ process provides a seamless, permanently bonded liner.
