Pipe joints and plumbing joints

Question

what r the uses of these types of joint's for any 1 that know be really helpfull

elbow joint

reducer joint

straight coupling

equal t

stop end

or does any 1 else know any other joint and there usess thank's adam

Answer 1

Homework time?

Answer 2

1. for carrying pipe around a corner ( can also bend pipe by hand and save a fitting.

2. To join two pipes of different sizes (ie. 22mm to 15 mm)

3.To join two pipes of the same size

4. for joining 3 pipes where they meet.

5.to blank off a pipe so no water can pass through it.

another joint is a pitcher tee which is like an equl tee but one branch of it is swept.

Answer 3

elbow joint--makes a turn, either 90 degrees or 45 degrees (two different items)

reducer joint--joins two pipes of different sizes.

straight coupling--joins two pipes of the same size

equal T--joins three pipes of the same size

stop end--closes the end of a pipe

Answer 4

depends on the type of material these joints are made of... brass?  copper? black iron? abs?  pvc?.  each of these types of plumbing pipes have these fittings, but all have different purposes...

elbows:  available in 90, 45, 22 1/2, and 60 degree bends.  used to change direction of the piping, or make offsets to miss obstacles.  22 1/2 and 60 available in ABS and PVC drainage pipes

Reducer:  in copper and Black iron, used to go from a larger pipe size, to a smaller one, when less flow is needed for the fixture/appliance being served.  this would be called an "increaser" if talking about ABS or PVC, as you never decrease a drain or vent size.  you ONLY increase in size.  this is done when enough fixtures are draining into the pipe to warrant a larger size.

coupling:  used to join 2 pipes together.  plain and simple.

T:  only in copper and iron, used to add a branch or to split a line into two seperate ones.

stop end:  (either a plug or a cap?)  used in copper and iron, to block off an unused line, or future line.  also used for pressure testing.  some are available for ABS and PVC, for testing.

this may also mean a clean out, which is a threaded stop.  this is used in drainage piping to allow access for augering, or rodding.

also available, are "fit-in" versions of most of these fittings, which would have a male, and a female end.  this allows you to stick 2 fittings together, without any pipe in between.

TY's, are used for plumbing, for allowing a horizontal drain pipe to connect to a vertically run pipe, or stack.  also allowed for use in venting systems.  these are plastic fittings, ABS, or PVC.

Y's, are similar to TY's, but the branch has a definite, clear direction, pointing towards the downstream end of the fitting.  these are used more commonly in horizontal applications, as TY's aren't allowed horizontally.

these are some common ones you have missed, but i could write a BOOK listing the rest of the possible available fittings out there.

go to a hardware store if you would like to see a larger (but still incomplete) selection of the fittings available.

Answer 5

A grass cone reefer joint for connecting you to the sofa.

Answer 6

elbow = right angle bend

reducer= makes a 10mm pipe fit a 15mm pipe

straight coupling= fits to stright peaces of pipe together. say you needed to join to full lenghts of pipe with no bends

equal t= is T shaped for branching off to diff ways

stop end= block the end of a pipe if it has no use
