Centrifugal Process
The centrifugal casting process produces a superior, high-density fiberglass reinforced polymer mortar pipe product. Because the process is fully computerized, all pipes of each size, stiffness, and pressure class have very consistent, high quality. All pipes also have a mold smooth exterior surface, and an equally smooth, centrifugally cast interior surface.

Outstanding Long Term Flow Characteristics
The outstanding long term flow characteristics are evident just by looking down the mirrored interior surface. Built to last into the next century the inner surface is highly resistant to corrosion. The combination of these two qualities provides you with the best of both worlds. Long-term solutions with minimal maintenance, Hobas pipe is made to order to meet and exceed your requirements.

Liner Pipe Installation

Liner pipes may be pushed or pulled into the existing pipe. The pipes must be inserted spigot end first with the bell end trailing. Typically the leading pope spigot end is protected by a nosepiece designed to rideup and over offset joints and other minor inconsistencies or debris in the invert. The pushing force must be applied to the pipe wall.

Existing Pipe Preparation

The existing sewer may be maintained in operation during the sliplining process. Obstructions such as roots, large joint offsets, rocks or other debris, etc., that would prevent passage or damage the liner pipe sections must be removed or repaired prior to installing the new pipe. Before starting the liner insertion, a mandrel is pulled through to ensure that the line is clear.

Connections to other Material Systems

Connections to other pipe material systems may be accomplished by several methods. Because of compatible OD's, Hobas pipes, 18" to 48", may be joined directly with ductile iron pipes using either our couplings or ductile iron gasket joints. In some diameters and applications, Fernco couplings may be suitable.
