Overview
They are all hand built by our skilled craftsmen. The 1/4” minimum thickness solid elastomer tube is continuous with the flange face. Multiple plies of rubber impregnated high strength polyester or nylon tire cord form the first pressure reinforcement over the tube. Arch swell in response to pressure and arch migration are virtually eliminated by criss-crossed layers of reinforcement that pass over the arch and around steel or ductile iron rings embedded on both sides at the base of the arch. Body swell is controlled by high strength fabric or spiral steel wire. Large diameter joints are often built with steel rings in place of the wire when in addition to internal pressure, external pressure resistance is important. External pressure may come from deep burial, shallow embankment under roadways or joints inside tanks.
Features
FEATURES:
- Robust design with integral rubber flanges for secure connections
- Available in butyl rubber elastomer from stock
- Available with optional control unit tie rods to prevent overextension
- Moves in both axial and lateral offset directions
- Any lower temperature systems requiring thermal expansion, settlement, or other movement where chemically compatible
TEMPERATURE: 230° F
Application:
Single Arch Rubber Joint can be widely used in water supply and drainage, water circulating, HVAC, fire control, paper making, pharmacy, petroleum chemical industry, shipping, water pump, compressor, air blower etc.
Common type(air, compress air, sea water, oil, acid) :－15℃～115℃, special type(strong acid, strong alkali solid materials) :－30℃～250℃
Common type used to convey from -15 to 115 centigrade air, compressed air, water, sea water, oil, acid and alkali.
Special type used to -30--250 centigrade over medium or oil, strong alkali acid concentration, solid-state materials.
