POLYBUTYLENE

PB TUBES ● Small bending radius

The bending radius of ZHONGcai POLYbutene PB pipe is
recommended to be 8 times the outside diameter of the pipe. When
聚丁烯（PB）管 bending the pipe directly, in order to avoid damage to the pipe, do 给水篇
not bend too hard. If possible, it is better to match the bending casing
at the bending part. If the pipe is bent, the pipe must be replaced. It
is recommended not to use pipe fitting for the part conforming to the
bending radius, which can not only save the initial investment, but also
ensure the continuity of pipeline and improve the construction speed.

● Resistance to frost crack and repeated freezing and thawing
Zhongtai polybutene PB tube has good flexibility and low
temperature brittleness resistance. The lowest temperature for
long-term use can reach -18℃. To some extent, it can absorb
the volume expansion caused by water freezing in the tube.

● Water hammer occurrence risk is small
Due to the high flexibility of PB, it can fully absorb all kinds of shocks
in the pipe, reduce the danger of water hammer, and at the same
time reduce the noise generated by the flow of fluid in the pipe to a
certain extent.

● Small linear coefficient, easy to compensate
Due to the flexibility and small linear expansion coefficient of
Zhongcai polybutene pipe, the temperature strain force of the pipe
is small, which is easy to be compensated. For the buried pipe
with small diameter, the compensation problem can be completely
ignored, and the hot water open-installed pipe can also be
compensated naturally by using clamping parts and local bending.

● Chemical resistance
Most solutions of zhongcai POLYbutene PB pipeline system are
resistant to acid and alkali salts, so they will not be corroded or scale
产品特点 formed due to water quality, which can ensure the long-term flow of
PRODUCT FEATURES pipelines remain unchanged.
