How to improve the pressure-bearing capacity of rubber soft joints
As hollow fittings used to connect pipes, rubber soft joints have a series of characteristics such as good ductility, high pressure resistance, small volume, easy and quick installation, vibration and noise reduction, and large offset. Rubber soft joints fundamentally solve the problem of pipelines and the problem of different pipe diameters. Rubber soft joints are mostly installed at the import and export of centrifugal pumps, that is, some places where the vacuum value is relatively large. At the inlet of centrifugal pumps, in this case, rubber flexible joints encounter the possibility of being sucked flat, because in this working environment, rubber flexible joints must withstand negative pressure.
 
The pressure resistance (strength) of the rubber flexible connection is determined by the structure of the rubber flexible connection itself, and the toughness of the rubber flexible connection is determined by the material of the rubber flexible connection. Multi-story buildings are increasing, and the pressure resistance of pipelines is getting higher. Therefore, the pressure resistance of the pipeline becomes an important consideration in the selection of piping materials. When the rubber soft connection needs to withstand high working pressure, the radial or axial offset range may exceed the specified value, or the customer has special requirements for the offset characteristics of the rubber soft connection, the limit device can be selected. The limit device is divided into three types: Type A - limit screw tightened on the pipe flange; Type B - limit screw welded on the pipe flange; both methods can limit the offset of the rubber soft connection within the range required by the customer.
 
The inner layer of the flange rubber soft connection is made of high quality polyester cord fabric and hard steel wire welded steel frame layer, which has excellent compressive strength to ensure that the rubber soft connection, not easy to stretch and tear during use nylon cord fabric is also very good at reducing deformation to restore the normal span, maintaining the ductility of the rubber soft joint and increasing the compressive strength of the tire bead layer rubber soft joint. The neck of the flange rubber soft joint increases the collar, which has good pressure resistance and ensures the weak part of the rubber soft joint, especially when used under high pressure above 2.0MPa, which requires modification of the secondary equipment. The fusion of all flange rubber soft connections has no weak points.
