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:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
Joint type end straight joint and a straight joint, three joints, elbow, with movable nut joint, hinge joint, plug, etc. transition joints double sleeve joint. The clasp, clasp, nut material used is stainless steel and copper metric, American and English standard thread standards NPT, PT, G is the pipe thread.NPT is National (American) Pipe Thread. The 60 degree taper pipe thread belongs to the American Standard, for North America. The national standard is available on the GB/T12716-1991
Q:Do you need adhesive for the sleeve joint of PVC wire pipe?
The Construction Code stipulates that this is true, but it is rarely used in general decoration.
Q:Hydraulic pipe joint seal, with raw meal belt and sealant that good?
Hydraulic is not high temperature oil, usually with O ring, can not seal the oil, is not the joint surface is not good, can not cut off the replacement of joints, raw rubber tape, sealant is not reliable
Q:Quick plug and card sleeve joint sealing which good?
1, small;2, standard type;3, metal type;4, stainless steel type;5, flame retardant;6, compound type;7 drum type joint body combination;
Q:Consult the problem of the pressure at the entrance and exit of the pipe joint
Assuming that your 3 oil outlet, load is infinite, as follows, three load (cylinder or motor) are not action, three outlet pressure is 2MPa, three outlet pressure gauge pressure is 2MPa
Q:Press the hydraulic pipe fittings standard need to do what procedures
The corresponding micrometer scale is 3. Installed with 33mm mold on the mold seat, and rotated to 3 micrometer scale, the hose peeling and joint assembly. After measuring the joint outer diameter of buckling is buckling parameter table after withholding value 33.5mm is withheld. If the diameter does not conform to withhold, after a fine micrometer withhold hose. Withhold hose connector: swage size too much, hose layer broken, causing leakage; too little buckling size, and hydraulic oil spill caused by rushing out of joint.
Q:How do I distinguish the rigid clamp joint and the flexible clamp joint from the outward appearance?
Length and thickness of flexible clamps.Clamp itself difference:Flexible and rigid joints of the same specifications: width is different, flexibility is wider than rigidity 2MM (take 159 clamps as an example)
Q:Why is the water purifier on the quick connector and contact Water Leakage PE
If the connection is fast, it's only possible to change the connector, change the connector and plug it into the bottom, then put the cards on it. After changing the line when the first card, then hold the joint to joint in force according to the pipe out, gently, not pull, pull the useless.
Q:Pipe joint thread, said in 2 / 3 / 4 points, what does that mean, how to convert ah?,
This appellation is the traditional British appellation, which is also used in the machinery industry for addressing the diameter of bolts4 in charge of diameter is 15mm (Dn15)6 points 20mm (Dn20)The pipe diameter is not 2 points, 3 pointsThe 25mm diameter pipe is called 1 inch tubeDn32mm inch tubeDn50mm 2 inch tubeDn75mm 3 inch tubeDn100 4 inches
Q:What do you mean by pipe fittings 3/4?
Supplement:1 inches =25.4 mm, =8 British points, 1/2 is four points (4 British points), DN diameter 15mm, 3/4 is six points (6 points), DN20mm.
