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 are the installation requirements of the card sleeve joint?
The sleeve type pipe joint has the advantages of simple structure, convenient operation and no need of welding. But in the middle and high pressure hydraulic system, if improper operation, often will cause leakage, and affect its popularization and use. After years of practice, the author summed up some experience, and achieved good results.As shown in the drawings, the sleeve type pipe joint is mainly composed of a joint body 1 with a taper hole of 24 degrees, a clamping sleeve 2 with a sharp inner edge and a pressing nut 3 and three parts which are pressed. Tighten the nut 3, card set of 2 is to promote the 24 degree taper and then deformation, make the card sleeve and the connector body cone to form a spherical contact seal; at the same time, the outer wall of the inner edge of the sleeve mouth embedded on the outer wall of the steel pipe 4, a pressure ring groove, so that the reliable sealing effect. The best choice of steel tube to eliminate stress annealing 20# fine drawing pipe, so that it is beneficial to insert the inner edge of the sleeve into the outer surface of the steel pipe, and play a reliable sealing role.
Q:Man, can you send me some national standards? Mainly for hydraulic use
Domestic standards, I do not have any standards, the domestic standards of learning German, learn from other countries standards, do very badly.SN standard pipe taper angle of 24 degrees and 30 degrees in China, can not mix.
Q:Very confused about the pipe fittings and the fittings, and can not distinguish them
The task is accomplished by the joint body, one end of which is connected to the pipe joint and the other end connected to the device
Q:Where can you buy fire extinguishers?
i might stay placed, and phone up emergency centers. there's a reason some elevator businesses do not comprise hatch doorways to a number of the elevators; some human beings are daft adequate to attempt and climb out. yet in spite of this, I continually take the stairs.
Q:Re series 24 degrees cone O ring seal pipe joint joint, corresponding to the national standard number is?
There are many kinds of pipe joints, and the commonly used pipe joints can be divided into two kinds: hard pipe joint and hose joint. If in accordance with the connection pipe joints and pipe points, hard tube joint with flared type, sleeve type and welding type three, hose connector is mainly buckling type hose connector.In hydraulic system, the connection way of pipe and pipe joint is different. The screw is used to connect screw thread. The taper thread is screwed on its own vertebral body and is sealed with polytetrafluoroethylene and other substances. It is mainly used in the hydraulic system of medium and low pressure. The sealing effect of fine thread is very good, is often used in high pressure system, but it requires the use of combination washer or O ring to end closed, sometimes used copper gaskets, it is suitable for the pipe connecting pipe wall is thick, the main part of a joint body, and take over nut. When in use, the joint body is embedded in the target, and the end face is sealed by using the gasket mentioned in the front; the rubber seal is used between the joint body and the connecting pipe, and sometimes the spherical sealing method is adopted.
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
Because it is clamping, used for steam to consider the impact of temperature, it is not recommended for toxic, harmful, medium pressure above the high temperature gas.
Q:G1/8 "pipe joint end special sealing WD-B02 is what mean
The sealing effect is better than the traditional O ring. The elastomeric seals are used as axial static seals for threaded oil and screw ends, and the cross section remains almost constant at high pressure.
Q:Most people have seen the model of the lung. How is this different from the actual lung itself?
I'm homeless and sleeping rough on the beach at the moment, so if lightening were to strike, I would fry.
Q:Infusion, infusion tube joints fall off and immediately connected, lost three or four minutes will have an impact?
There is no air on the upper end of the infusion pipe, the joint is not polluted, and immediately after the falling off, the problem is not too great. The switch on the upper end of the infusion tube is not closed. The liquid medicine can be discharged directly and immediately after falling off, so there is nothing wrong with it.
Q:How do we know that gravity propogates at the speed of light?
Actually, you won't qualify for unemployment if they fired you for no call, no show. I would ask them if they have any Documentation of the counseling that took place or if they can show you a schedule that proves you were scheduled to work. As ist stands right now, you won't qualify. You really need some back up to present to the Unemployment office
