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:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
The twenty-first page specifies the level of thread and material corresponding to the pressure application. Stainless steel thread used in the steam is 7 kg pressure (bar), the water temperature is above 105 degrees celsius. Other restrictions, standards.
Q:I had to use a kitchen extinguisher when food caught fire inside my stove. I'm unsure about how to clean up the residue left on the inside.
if it is a copper pipe it might be loose in the fittings, if you really do not have the moneyfor a plumber, try using plumbers puttyaround the leak make sure the area is dry, plumbers putty will not stick if it is wet, or, duck tape it, good luck, let me know if this works
Q:My husband and I are trying to figure out how to save money on all our bills: electric, home gas, water, and grocery. Grocery is kind of obvious For electric, we obviously turn out all lights when not in use and we also let our dishes air dry. For home gas, we wash all our clothes in cold water and turned the heat from 67 to 60 degrees. We have re-sealed the doors and windows. For water, we only wash dishes in dishwasher and do laundry when it is full. No small loadsAnything you can add to this?

Q:I have 1998 lifted dodge ram. Its lifted about 6-8 inches approximately. The steering wheel has a lot of play in it. If I'm turning left, I have to turn the wheel past 10 O'clock until it actually starts to make the turn. Same for when I'm going right, past a 3 O'clock till it starts the turn as well. When I'm driving straight, the steering wheel itself turns which makes the truck go left and right on the road. It was just aligned a few weeks ago and that's when I bought it but I don't know if it did that before. Any help Appreciated!!! I'm sixteen years old and trying to learn so thanks for any advise! Also, the truck has on 32 snow tires with the studs taken out right now
When threading isn't possible, then the use of rated compression fittings is usually desired. However, if your pipes are corroded, compression fittings might collapse the remaining pipe. If compression fittings do not work, then welding or complete replacement are the only other options.
Q:I have fears that effect my everyday life. They would be a fear of hippos (pretty bad) and fear of wrists (extreme) and a fear of tooth picks (bad).The hippos; are cause when I was little I was pushed into a hippo exhibit at the zoo.The wrists: are for stories about cutting and stuff. It's so bad. I cry and hypervenilate and dry heave. It's horrible. And toothpicks: are because they're sharp and pointy. I can't stand them. How can I get rid of these? Seriously, they're taking over!!!
with images on your computer no, as far as doors standing wide open mine do that too, try opening the door yourself, and see if it stands open, open up the surrounding iwndows for one try and close them for another, the thing is when you want to consider your house haunted you have to rule out every possible excuse to the best of your ability
Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Two, flexible pipe joint clamp type flexible pipe joint ring part and the pipe connection is socket welding, so as to facilitate the installation, the product imported from America, KRJ is the butt welding, which is helpful for pipeline installation, the details can query the professional manufacturers to askThree, ring thickness of flexible pipe joint is greater than 30 mm, which can increase the wear resistance of air impact according to the principle of friction, the latter is only considered high pressure, without considering wear so over 16 mm in thickness general below.
Q:On the pipe 1216141816202025, is it for 4 points, 5 points, 6 points, 1 inches of ground heating pipe?
4., antistatic, easy to flammable fluid delivery;5. good electromagnetic shielding performance;6., good flame resistance, to achieve GB8624 refractory (B1) level;7. good insulation performance.(two) hydraulic performance of aluminum-plastic composite pipe inner surface roughness of thin wall excellent, very smooth, fluid friction resistance is small, no fouling phenomenon which affects the flow of water flux than the metal pipe, and because it has a certain flexibility, can effectively reduce the water supply of water hammer and fluid pressure shock and noise.
Q:Like the part that goes through, you knows. Like holds/locks it.
Did you clean the pipe and the fitting with a wire brush? did you put flux on both after cleaning it? if so you have to heat them both up with a torch until they are really hot. the solder will not take if they are not hot enough.. flux is very important also try that then leave the torch on the joint you want to solder for a bit longer then try again, if it is still happening, keep heating it and try again. evenually you will get it.. I use mapp gas, but propane works also for your torch mapp gas burns hotter and heats them up faster. oh. are these new pipe and fittings? if so try above, if they are old, you have to make sure ALL of the water is out of the lines, or it will take you a VERY VERY long time to heat them up enough to solder, because the water cools the joint and the pipe, it has to turn the water into steam then the pipe will eventually heat up
Q:Ive recently moved into a shared house where the internet access is controlled by the foreign couple I live with ) I.E they have the contract with the I.S.P the router is in their bedroom. Now although I have no reason to dis-trust them really, they do seem to spend alot of time in thier room claim 'not to watch much T.V but to go online alot'..I read of a way to be able to tell if another computer on the same network as me can have or is accessing my computer but can't quite remember the procedure, any help on this matter or advice would be greatly appreciated and before anyone states the obvious and suggets I get a seperate internet connection for my room, yes I am aware of this and am infact giving it serious consideration due to the fact I don't want any online banking info getting into the wrong hands!
Guess what. It's the gloves that make me queasy. That's because I know that many of those people wear the same gloves all day and never clean or change them. At least with the bare hands, there is a continuous hand washing going on. And nothing is worse than the gloved hand that goes and touches something gross and back to the food. Do you wear gloves when you prepare food at home. Neither do I. That's because we wash our hands before touching food, just like food preparers must. Food safety law is a state issue and usually administered by counties.
