Water and electricity decoration pipe fittings are indispensable, their types are many and complicated, do not understand the students in the first contact is very easy to mix, which leads to the hardware store or home building materials market when buying the wrong pipe fittings and leakage to buy some pipe fittings are very normal, in order to prevent unnecessary losses, Now let's introduce you to PPR. What are the names of various pipe fittings? Let's take a look.

PPR What are the names of various pipe fittings? Ten common pipe fittings are briefly introduced

1, three: also known as three road day, day word bend, T-shaped bend. It is used to connect three pipes with the same nominal pressure diameter or pipe fittings and gate valves with pipe threads, in which two pipes are in a straight line, and the other pipe is vertical with the two pipes. For the area where the branch line must be connected.

2, four: also known as the cross joint, four road day, four fork. It is used for the middle connection between the main road and the two side branch pipelines. Four of the same diameter and variable diameter two. Mainly used in the transport of gas pipelines, so that the pipeline into a cross branch. The application field is smaller than TEE.

3, reducing tee: the main use is similar to tee. However, the nominal pressure diameters of the three ends are not completely the same or all different, and the end used for connecting the riser can be vertical with the nozzle end, or can be at a 45° Angle with the nozzle end.

4, bend pipe: also known as 90° bend pipe, wild stream, bend head. Consisting of threads for joining two pipes of the same nominal pressure diameter for 90° steering.

5, the outer crescent: also known as the outer wire crescent, crescent. The main use is similar to the bend pipe. It has a larger radius. It is mainly used in pipelines with large bending radius. The outer moon bend with pipe thread, and pipe connection needs to be used with the external joint.

6, 45° bend pipe: also known as straight bend, half bend. It is used to connect two pipes with the same nominal pressure diameter or pipe fittings and gate valves with pipe threads, so as to make the pipe turn 45°.

7, reducing elbow: also known as size bend, size bend. It is used to connect two pipes with different nominal pressure diameters or pipe fittings and gate valves with pipe threads, so that the pipe can be turned 90° and the diameter of one end of the pipe can be reduced.

8, live joint: also called connection nut or live screw. It is composed of two joints and a protruding surface. The surface is located in the middle of the two joints and the two joints are connected to each other, using it can be very convenient to install and remove the joints during maintenance.

9. External joint: also known as sleeve specification or direct head. The external joint contains threads, which are generally connected with two pipes with the same nominal pressure diameter, or pipe fittings with threads and gate valves. It is a kind of water-heating installation connection with a large dose.

10. Variable diameter outer joint: also known as variable diameter sleeve specification or eccentric size head. A pipe of different types with different nominal pressure diameters at both ends.

In addition to some of the plumbing fittings mentioned above, the most common ones are anti-loose nuts, hexagonal inner joints, inner and outer nuts, pipe blocking, inner tooth tees, inner tooth live joints, outer tooth live joints, equal diameter live joints, bridge bend, loose ball valve, loose sleeve flange parts, closed head, inner wire elbow, outer wire elbow, bunching joint, gate valve, triangle valve. Other we can go to the home building materials market to understand.
