Product Description

   

Brief introduction

1, The appropriate model must be selected according to the working pressure of the pipeline, the connection mode, the medium and the compensation amount, and the number should be selected according to the noise reduction displacement requirements. 2 ,When the instantaneous pressure of the pipeline is greater than the working pressure, the joint of one gear higher than the working pressure should be selected. [For example, when the instantaneous pressure of the pipeline is >1.0MPA, a worker should be selected as a 1.6MPA joint. When the instantaneous pressure is 1.6MPA, a 2.5MPA joint should be selected.] 3,When the pipeline medium is acid, alkali, oil, high temperature and other special materials, a joint higher than the working pressure of the pipeline should be selected. 4, The flange connecting the rubber joint shall be a valve flange or a flange conforming to GB/T9115.1(RF).

5,The normal suitable medium for flexible rubber joints is ordinary water with a temperature of 0-60 ° C. 5, special media such as oil, acid and alkali, high temperature and other corrosive and hard texture, should choose the corresponding material rubber joints, can not be blindly used or universal. 6, When the flexible rubber connector is used at the inlet and outlet of the pump, it should be located near the pump side, and a metal reducer connector should be installed between the pump and the pump, and installed at the large diameter of the reducer. When the maximum compensation amount of the pipe displacement 2 joint, the number of joints should be increased to parallel the displacement amount. It is strictly prohibited to adjust the excess of the pipe, so that the joint 7 is in the limit of the disturbance displacement and deviation state, and can not exceed the limit [expansion, displacement, deflection, etc.], high-rise water supply or suspended water supply, the pipe should be fixed on the hanger, bracket or anchor. 7,And can not let the joint bear the pipe's own weight and axial force, otherwise the joint should be equipped with anti-pulling device (its bearing force must be greater than the pipeline axial force). When installing the rubber joint, the screw of the bolt should extend to the outside of the joint, and the bolt of the end face of each flange should be repeatedly and evenly tightened by the method of diagonal pressure to prevent the pressure of 8 deviation.

8,The wire joint should be tightened with a standard wrench, and do not use an extension rod to make the live joint slip, slip edge and fracture, and should be checked regularly to avoid loosening caused by disconnection or water seepage.

9 ,After the rubber joint is subjected to pressure for the first time (such as installation pressure test, etc.) or before being used again after long-term disuse, the bolts should be re-pressurized and tightened before being put into operation. 10 ,When using or storing rubber joints, avoid high temperature, ozone, oil and acid and alkali environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and exposure, rain and wind erosion are strictly prohibited. Do not paint or wrap insulation materials on the surface of the joint. Due to the aging problem of rubber products, it should be checked and replaced in time.

EPDM	Good resistance to hot water and steam, detergents, caustic potash solutions, silicone oil and greases, many polar solvents, and many diluted acids and chemicals, along with a high level of ozone resistance. EPDM materials are totally unsuitable for use with all mineral oil products (lubricants, fuels).
FKM	Good chemical resistance to mineral oils and greases, synthetic oils and greases, engine, transmission and ATF oils to approx. +150°C, fuels, non-flammable hydraulic pressure fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons, water to max. +80°C, excellent resistance to weathering, ozone and ageing, very low gas permeability (and therefore excellent for vacuum application) and resistance to a wide range of chemicals.
HNBR	HNBR is obtained by fully or partially hydrogenating NBR. It leads to considerable improvement in resistance to heat, ozone and ageing, and gives it very good mechanical properties, e.g. good resistance to wear. The media resistance compares to that of NBR. HNBR has a good resistance to some refrigerants. The temperature application range is from -30°C to +150°C.
NBR	Good chemical resistance to mineral oils and greases, hydraulic oils H, HL, HLP, non-inflammable hydraulic pressure fluids HFA, HFB, HFC to approx. +50°C and water to max. +80°C
VMQ	Good resistance to water (up to 100 °C), aliphatic engine and transmission oils, animal and plant oils and fats. VMQ is generally not resistant to fuels, aromatic mineral oils, steam (short term up to 120 °C possible), silicone oils and greases, acids and alkaline compounds.

FAQ

1. What is your MOQ ?
Usually our MOQ is 1000 pcs. But we accept small quantity for the first trial order.
 
2. Can I get sample ?
Sure. We usually provide existing sample for free. But a little sample charge for custom designs. Sample charge is refundable when order is up to certain quantity.
 
3.How long is the sample LEAD TIME?
For existing samples, it takes about 2 days. They are free. If you want your own designs, it takes 3-7 days, subject to your designs whether they need new printing screen, etc.
 
4. How long is the production lead time?
It takes about 15 days for MOQ.
