Polymer Concrete Pipe Polymer Concrete Pipe

The
Manufacturing Process and Physical Properties

We manufacture Polymer Concrete pipes with a
vibration process, in which exact amounts of each material are mixed and
loaded into vertical metallic molds consisting of an inner mold and an outer
mold. The amount of each material and the specific mixing sequence required
are controlled by a computer program for each pipe. After compaction of the
vibrating table each pipe cures in a tunnel kiln. Circular and oval pipes as
well as special cross-sections such as manhole shaft pipes, cones and other
auxiliary components are manufactured in the same way. The pipe joint is
manufactured from glass fiber reinforced polyester resin as a separate
connector coupling by the winding process. The elastomer, sealing and spacer
rings are laminated in with the same process. The couplings meet the
requirements of DIN (Deutches Institute of Norman – German Standard) 4060
Elastomer Seals for pipe joints in drains and sewers. This standard is
comparable to ASTM D4 161 “Fiberglass Pipe Joints Using Flexible Elastomer
Seals”. The pipes are joined by means of a structural filament wound sleeve,
over-wrapped and mechanically locked to an internal full-faced elastomeric
membrane. The sealing design includes both lip and compression elements so
the joint is suitable for non-pressure and pressure service up to 2.8 bars
(40 psi).

Advantages of
using Polymer Concrete

•
High compressive strength = High jacking force and maximum safety• GRP joint collar = Maximum safety during jacking• Smooth outer pipe surface = Reduces friction• Parallel pipe ends = Provides uniform distribution of jacking
forces

• High dimensional accuracy = No Out-of-Round, tight joints and
perfect match

• Elasticity = Reduced point loading and risk of rupture

•
Low weight = Ease of installation• Adaptable dimensions = Suitable for all micro-tunneling and
jacking equipment• Smooth, even inner surface = High flow rate• High corrosion resistance = Reliability throughout a long service
life

• Complete systems = Jacking pipes, open cut pipes and manholes
