China Jingning Dn30-Dn3000 Flange Rubber Flexible Connector
Expansion Joint
Rubber flexible connector can also be called: flexible rubber
joint, rubber soft joint, soft joint, flexible rubber joint, etc.
Rubber flexible connector is a pipe connector with high elasticity,
high air tightness, medium resistance and weather resistance.
Rubber flexible connector is a kind of composite rubber pipe which
is composed of inner rubber layer, fabric reinforcement layer (the
reinforcement layer has multi-layer scraped nylon cord), middle
rubber layer, outer rubber layer, end reinforced metal ring or
steel ring, and loose combination with metal flange or parallel
joint after high temperature and high pressure vulcanization. The
rubber flexible connector makes use of the advantages of rubber,
such as high elasticity, high gas resistance, medium resistance,
weather resistance and radiation resistance. Rubber flexible
connector can reduce the vibration and noise of the pipeline, and
compensate the thermal expansion and cold contraction caused by
temperature change.
Performance characteristics of rubber flexible connector
1. The decompression effect of rubber flexible connector is
reliable, and the outlet pressure is not affected by the inlet
pressure and flow rate. It can reduce both dynamic pressure and
static pressure, and keep the set outlet pressure constant.
2. The rubber flexible connector is easy to adjust and operate.
Just adjust the adjusting screw of the pilot rubber joint to obtain
accurate and stable outlet pressure.
3. The rubber flexible connector has good energy saving effect. The
rubber joint body adopts full channel streamline DC design, with
small pressure loss, large flow, small volume and light weight.
4. The rubber flexible connector has a long service life, and the
important parts are made of special materials, so there is no need
for maintenance.

Note: 1. The special requirements of rubber flexible connector can
be customized according to user's drawing. Flange standard is GB /
t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN,
BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The
rubber ball of rubber flexible connector can be used as natural rubber, EPDM, chloroprene rubber, butyl
rubber, butadiene rubber, fluororubber, etc. when the rubber flexible connectorabove DN200 is used for suspension water supply, the pipeline must
have fixed support or fixed support, otherwise the rubber flexible connector shall be installed with anti falling device.

Do you know how is a rubber flexible connector made?Let's see with
JINGNING.
It is very important to know the compatibility between the medium
of rubber flexible connector and the selected rubber flexible connector material, the range of full temperature, full pressure and full
vacuum, the required movement of rubber flexible connector, and the size between pipe flanges when selecting the appropriate
rubber flexible connector. With this information, Jingning application engineers can help
determine the ideal rubber flexible connector for any application.
