The form: this product consists of rubber pipe ,made of inner glue
,multi-layer proofinf and cord fabric and outer glue abd metal
woggle joint .It is applicable for the connection of inlet and
outlet pipes of various fancoil sets of air conditionings in the
guest rooms of hotels and restaurants.
1. All expansion joints are finshed with retaining flanges,limit
rod units are available on special request.
2. Pressures shows are recommended“operating”,test pressure is
1.5time“operating”,burst pressure is 3 time “operating”.
3. Vacuum rating is based on neutral installed length without
external load.Products shall not be installed “elongated”on vacuum
applications.
4. Do not weld near the expansion joints or weld the steel flanges
to the piping after the expansion joints are installed .This will
either burn or seriously damage the expansion joints.

Thread connected pipe coupling advantage
A: 15 minutes zinc plating, high pressure resistance, high
temperature resistance, oil resistance, wear resistance, corrosion
resistance, acid and alkali resistance.
B: Connect with pump, valve, fire fighting equipment, pipe which
vibrate big, pipe which hot and cold change frequently.
C: Natural rubber content of forty-seven percent, can continue to
use for 15 years without aging.
