Gongyi Hengzhong Water Materials Supply Co., Ltd
Rubber expansion joint reach nearly one hundred series, thousands of specifications, including five series of patent products. Rubber expansion joint are flexible rubber joints, reduced rubber joints, rubber elbows, fan coil joint, sewage check valve rubber, rubber filter, rubber compensator air flue compensator, flexible hanger, rubber shock pad, shock absorber, pipe damper, seal, gate valve,check valve, foot valve, filters, valves, pressure balance valve, valve, butterfly valve, pipe expansion joints, bellows, waterproof sleeve tube, power delivery Joint, limit expansion joints etc.rational product design is unique, novel structure, reliable performance, to engineering construction and maintenance bring great convenience and benefits.
Rubber expansion joint Application:
The flexing double balls rubber joint-JGD-A1 is widely used in chemical industry, building, water supply,
water drainage,petroleum, light and heavy industries, frozen, sanitation, plumbing, fire control, power etc.
Metal Hose,Bellows, Rubber Hose, Rubber Joints, Expansion Joints.
Rubber expansion joint installation:
One, in a flexible rubber joint pipeline construction, must be in the state of nature, not man-made products produced artificially deformation during installation.
When the pipeline medium for acid and alkali resistant, oil, high temperature, and other special materials should be chosen when above the pipeline working pressure of a gear coupling.
Two, connect the rubber joint flange should be the valve flange or is in line with GB/T9115.1 (RF) of the flange.
Three, can be bent around the rubber joint normal applicable medium is a normal water temperature 0-60 ° C, such as special medium: oil, acid and alkali, high temperature and corrosion resistance and other hard cases, should choose relatively deserve special rubber joint resistant material, not blindly use or gm.
Four, in a flexible rubber joint used in the import and export, the pump should be located in the Wells of water, and the springs of water shall be installed between the metal joint variable diameter, and installed in a variable diameter of large diameter of the source.
Five, when the pipe joint displacement quantity is greater than or equal to the largest amount of compensation, should increase the number of joint to parallel displacement, it is strictly prohibited to adjust the pipeline of super bad, make the Rubber expansion joint in the limit state of flexure displacement and deviation, more can't exceed limit (telescopic, displacement, deflection, etc.), using specific installation data as shown in the table below.
Six, top or impending water supply, water pipes should be fixed on the hanger, bracket, or anchor frame, and cannot make joint pipe under its own weight and axial force, otherwise the joint should be equipped with protection pulled off (the tolerances must be greater than the pipe axial force).
Seven, installing a rubber joint, joint screw should be extended to the outside of the bolt each end of the flange bolts according to the method of diagonal compression repeatedly evenly tighten, prevent partial pressure. Threaded connection should use standard wrench tight uniform force, do not use a torque stem strength makes the union slippery silk, smooth edges and fracture, and to periodically check, lest cause off or loose.
Eight, soft rubber joints in the first time under pressure (such as: installation testing, etc.) or disable before enabling the again for a long time, after should tighten bolts back pressure and put into operation.
Nine, Rubber expansion joint use or storage of soft , ozone should avoid high temperature, oil and acid and alkali environment. Used in outdoor or xiangyang wind pipe should build sunshade frame, it is strictly prohibited to waste their, rain, wind turbidity. It is forbidden to paint and winding insulation joint surface.
