| Introduction |
Era PVC-U Rib pipe,with inner smooth wall and outer
enforced rib ,is scientifically structured and mainly applied
in underground wastewater drainage and sewage. Due
to the scientific design,rib pipe has excellent physical
mechanical properties. Rubber ring ensures leakage
resistant connection,convenient installation and reliable
application. The lifetime of Era rib pipes is guaranteed to
be over 50 years and expected to reach 100 years.
