Top ten skills of installed in a flexible rubber joint

1, flexible Rubber Joint pipeline construction is necessary to let the man in the natural state do not occur in equipment goods artificially deformed. When the pipeline medium is acid, oil, heat and other special items should be chosen higher than the working pressure of a pipeline stall connector. Rubber joints can be curved around normal for medium temperature 0-60 ° C is ordinary water special media such as oils, acids, alkalis, and other corrosive high temperature and texture should be used in the case of solid corresponding information was resistant special rubber joints not blindly string with or universal.

2, convergence flange Rubber Expansion Joint flange or valve should be fit GB/T9115.1 (RF) flange. GJS (X)-A type JGD / KXT rubber joints in all types of equipment shall be so outstanding unit sphere two sub-reinforced rope ring full Karufalan pressure tank to prevent the joint when the ball off on the Falan La bolts first symmetrical hexagonal bolts or four balls tightened to ensure the full and the flange in place.

3, Rubber Expansion Joints with pipe flange bolts when convergence toward the pipe flange screw should be threaded at one end to prevent the pressure arch rubber joints swell when some bruises or stabbed each end of the bolt is necessary symmetrically pressurized Tighten all bolts tightness of the joint. So harsh environment  addition to adding the outer flat washer should be added stretched spring washers. To prevent the nut loose.

4, if the use of high-curvature arch rubber joints or bolts Hexagon difficult due to the need to use through flange hole and try to cut the ball stud threaded ends to prevent some outstanding ball was injured when the swell pressure rubber joints early damage. Flexible rubber flexible connector used in the pump should be located springs export should be between one side and the equipment metal springs and adjustable joints of large diameter device adjustable provenance.

5, when the pipe joint displacement greater than or equal to cover the amount of the maximum number of joints should be added to the ban in order to adjust the amount of displacement parallel to the pipe joint is super errand limit deflection displacement and the error condition but can not exceed the elastic limit, displacement, deflection, etc. detailed device data using the table below.

6, high water or floating in the water pipes should be fixed hangers, brackets or anchor bracket connector accepts pipeline itself does not allow axial force component and otherwise shall be equipped with anti-pull connector device (which accepts pipeline axial force than necessary force). The use of large-diameter rubber DN1000mm more joints for ease of equipment and labor intensity should decrease manufacturing a flange at one end of the short length of pipe to be appropriate rubber joints and the other end of the short pipe pipeline linking the future, then the short end of a long tube and pipe welding counterpart .

7, the device rubber joints  screw bolts should be toward the outside of each joint flange face bolts approach by diagonal compression evenly tightened to prevent repeated partial pressure. Threaded joints should be applied evenly wrench to tighten the norms do not use afterburner afterburner stalk the union slippery silk, smooth edges and cracking  and to regularly check to prevent loosening constitute off the plate or seepage.

8, soft rubber joints in the first time to accept the pressure test equipment such as pressure or after a long time out again from scratch before the opening  pressurized tighten the bolts should be operational again. When the rubber joints in water pump outlet close or open when stopping frequently to reduce the use of rubber joints long stretch and squeeze too much impact to the pipe flanges should add two limit device.

9, use or storage of soft rubber joints to prevent heat, ozone, oil and acid-base environment. Used outdoors or in a sunny shade should be established against the wind pipe rack prohibit violence Sai, rain, wind cloud. Joint appearance prohibit painting and surround insulation material. Rubber products due to the presence of aging doubt should promptly check replaced. Convergence in the implementation of the metal being welded flange material and remember that things will weld with a rubber cover to cover to prevent the welding joints burn sphere.

10 To facilitate short pipe welding deformation due to the radial error should be constituted before welding or other appropriate strength with round metal object put two pipe flanges being welded joints with a rubber flange convergence at such short tubes constitute a rigid body after the completion of the welding material welding remove.
