| Introduction |
Era PVC-U DW pipe is featured
by two layers, inner smooth wall
and outer corrugation,and mainly
applied in underground wastewater
drainage and sewage. Due to the
scientific design, DW pipe also has
excellent physical mechanical
properties. Rubber ring ensures
leakage-resistant connection,
convenient installation and reliable
application. The lifetime of Era DW
pipes is guaranteed to be over 50
years and expected to reach 100
year.
