Circular and non-circular pipes,
joints and fittings for nearly all
corrosive piping applications

CC-FRP

Description

HOBAS (CCFRPM) Pipes are centrifugally cast, glass-fiber-reinforced, polymer mortar. These large diameter pipes are ideally suited for nearly all corrosive piping applications. HOBAS pipes may be installed by a variety of installation methods. HOBAS pipes can be economically designed for non-pressure and pressure service by varying the quantity, placement, and orientation of the glass-fiber reinforcements. The figure below shows a typical cross-section of a pipe consisting of a fiber-composite laminate. The raw material compositions of each layer can differ depending on the application. For instance, the thickness of the inner core can be reduced, or the core even removed for higher pressure classes.

Product Benefits

Long Life
  • Superior inherent corrosion resistance of the pipe materials results in a long, maintenance-free service life.
Easy Installation
  • High stiffness design yields predictable and reliable pipe performance using installation methods routinely specified for traditional pipes.
  • Push-together joints assemble simply and quickly
  • Lightweight pipes handle easily and safely.
Fits Standard Pipe Accessories
  • O.D.’s match ductile iron dimensions so standard saddles, taps, fittings, couplings, clamps, joints, etc. are compatible and readily available.
Easy To Specify
  • ASTM and AWWA standards cover most applications and product tests. To receive guide specs, please leave a message.
Fast Field Length Adjustments
  • Constant, smooth O.D.’s permit the pipe to be cut and joined anywhere with the HOBAS FWC sleeve coupling.
  • Closure couplings assure quick tie-in connections with a positive seal.
Leak-Free Joints
  • Rubber-ring-sealed bell-spigot and coupling joints provide fast, fool-proof assembly and long-term, leak free service.
Performance Confidence
  • Worldwide, 50 year history of success documents HOBAS’ service tested and time proven performance record.
  • Over 35,000 miles of pipe in service worldwide.
  • To receive a list of installations in the USA, please contact your area manager.
High Flow Capacity
  • Oversized pipe I.D.’s and the glass-smooth interior surface result in the highest flow capacity available and significant power saving in pumped systems.
Lower Project Cost
  • Increased competition from HOBAS pipes has consistently resulted in substantial reductions in pipe prices.
Consistent Quality
  • Computer controlled production process assures consistent, high quality pipes.
  • Tested to ASTM and AWWA standards.

Constant, smooth O.D.’s permit the pipe to be cut and joined anywhere with the HOBAS FWC sleeve coupling

NC-FRP

Description

Many US cities started building modern sewer systems in the late the 19th century. Still in service today, the large sewers with specially shaped cross sections are the result of great feats of engineering and the foresight shown by the city fathers at that time. After such long periods in use, however, rehabilitation often becomes inevitable despite regular maintenance. HOBAS NC profiles, with their non-circular cross sections, are ideal for rehabilitating these old sewers or building new ones. HOBAS can also provide manhole renovation solutions and reline older pipes.

Manufacture HOBAS NC pipes feature a particularly resin rich inner layer. Pipes are designed for specific loads and project requirements, while also taking structural dimensions, customer specifications and regulations regarding chemical resistance into account. During installation, the pipes are pushed or pulled into the existing pipeline and the remaining annular space between the host and liner pipes is filled with grout. This fixes the inserted pipe in position, creating a pipeline of the very same integrity as a new one.

Shapes / Profiles
  • Kite-shaped
  • Egg-shaped
  • Elongated egg-shaped
  • Jaw-shaped cross
  • Jaw-shaped with dry weather channel

The range of available HOBAS NC cross sections is just as varied as the history of wastewater disposal itself. In addition to classic cross sections, such as circular, egg, jaw, or kiteshaped pipes, we manufacture additional combinations of shapes to customer request. Having perfected the necessary manufacturing technologies, HOBAS is regarded as a specialist for solving complex rehabilitation problems. Our product range also features shafts and manholes. HOBAS can supply customers with a complete system including pipes with special cross sections, lateral connections and manholes
