Application Introduction of Wide Range Flexible Coupling

 

The Universal Couplings are designed for pipelines as a wide tolerance system. it will fit most standard pipe materials and therefore dramatically reduces the number of dedicated Couplings,which need to be stocked for maintenance purposes. It is suitable for steel, GRP, PVC, PE, Ductile Iron, Cast Iron and Asbestors Cement. When connecting PE pipes, It is important that pipe inserts are fitted to the PE pipes.

Process & Installation Instructions of Wide Range Flexible Coupling

 

1. Examine the pipe ends and ensure they are round, smooth, free from buldges, dents and score marks and within the outside diameter range given on the adaptor label. Weld beads must be ground flush maintaining correct surface profile. Ensure that pipe ends are free from scale rust or any loose debris or other surface defect that may affect coupling performance.

 

2. Check grade of gasket is suitable for the conveyed medium.

 

3. Align pipe to be laid with pipe already in position, taking care that pipe ends are concentric, adjusting support or trench bed as necessary.

 

4. To aid installation, mark both pipe ends at a distance equal to or greater than half the overall coupling assembled width of the coupling. Place wholly on one pipe end.

 

5. Adjust setting gap between pipe ends as necessary.

 

6. Using marks made at step 4, slide the coupling to a central position over the pipe ends and commence bolt-up.

 

7. Tighten diametrically opposed bolts giving the nuts one or two turns at a time to draw up the end rings evenly. The bolts must be thoroughly tightened to the figures given below, working around the coupling as many times as necessary. On completion, the radial gap between pipe end coupling should be even all the way round rubber may be seen to extrude into the gap.

Q:What do you mean by pipe fittings 3/4?
Generally speaking, the standard is different, the corresponding caliber is also different. I don't know which one you're referring toThe pipe can be divided into many categories, there are pieces of pipe and socket welding pipe fittings, pipe trench, pipe fittings, sanitary fittings and so on. These fittings reference standard is not the same, even pieces of pipe standard also has many kinds, domestic GB/T12459, American Standard use of ASME B16.9 and ASME B16.28, and JIS2311 DIN2605 of Germany, Japan, and so many. GB GB/T12459 is divided into two series, the same "3/4" pipe fittings, the corresponding caliber is not the same. A series of peripheral dimensions and American Standard is basically the same, with the Russian standard size B is basically the same. So it's difficult to answer what the outside diameter of 3/4 is, and you need to refer to different standards. You can go to the "standard sharing network" above to check the corresponding standards, routine standards can be found, very practical!
Q:Hydraulic pipe joint seal, with raw meal belt and sealant that good?
It is best not to use, with American conical teeth hard seal, NPTF generally very few people with this. High precision ah!
Q:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Normal: a thin tube (pressure pipe) cool or lukewarm, thick tube (tube) cool or cold dew.
Q:Hot tap water pipe joint leakage, what method can be repaired?
If the water pipe is thicker, you can use the hot melt machine directly in the external welding, the gap will be blocked, this method can not have too high pressure.A solder gun can also be used to spray solder directly into the solder joint, which can be used with the PP-R patch.
Q:Will that be all right? Then there's the PPR pipe joint on the right. Is that ok?
If you don't feel comfortable, you can ask the master to change it for a whole 2 meter tube.
Q:What is the taper angle of flared tubular joints?
One end of the pipe is expanded to form an inner cone surface consistent with the cone angle of the pipe joint, the angle of the cone is 74 DEG, and the outer cone is the same as the angle of the inner cone of the pipe mouth, and the angle of the conical face is 66 deg.
Q:What are the standard drawing numbers for hydraulic couplings?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and blowing with high pressure air before use.When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure.If the pre loading force is unfavorable, the inner edge of the ambassador card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
Q:Hot melt pipe joint leakage how to do?
3, with polyurethane waterproof powder (generally used in toilet waterproof), after water transfer brush in the water leakage.4, with weather glue hit in the water leakage.
Q:Outside the wire (wire) of what the standard joint size
External thread type metal hose jointStructure and characteristics:The outer threaded end type metal hose joint is an extension of the JB/GQ0552-83 metal joint;
Q:What is the function of the pipe joint?
The hydraulic pipeline is mainly to transport hydraulic oil, the pipe joint is mainly for connection, installation and maintenance convenience.
