There are many applications for water supply pipes, so the specifications of water supply pipes also vary. Therefore, when choosing, everyone must pay attention to the selection of product specifications.

What are the specific specifications of water supply pipes?

The general specifications of household water pipes include: DN15 (4 pipes), DN20 (6 pipes), DN25 (1 inch pipe), DN32 (1 inch 2 pipes), DN40 (1 and a half inches pipe), DN50 (2 inches pipe), DN65 (2 and a half inches pipe), DN80 (3 inches pipe), DN100 (4 inches pipe), DN125 (5 inches pipe), DN150 (6 inches pipe), DN200 (8 inches pipe), DN250 (10 inches pipe), etc.

The meaning of a water pipe with a diameter of 25 × 1/2 is that its outer diameter is 25. The actual corresponding nominal diameter is DN20 (commonly known as 6 tubes). You can buy a 6-point faucet. You can also buy a 4-point faucet (just add a variable diameter between the pipe and the faucet).

The styles and materials of household faucets vary greatly, but the threaded parts connected to the pipes are classified according to sizes such as 4 inches, 6 inches, and 1 inch. Don't worry about buying the wrong one.

The commonly referred to 4-branch pipe is measured in inches, so 4-branch pipe is 1/2 inch (4/8=1/2), and one inch=25.4mm. Therefore, the inner diameter of 4-branch pipe is 25.4/2=12.7mm, which is commonly referred to as the inner diameter of DN15 water pipe.

4 minutes is the name for the diameter and length of British pipes, which means 1/2 inch is equal to 15mm in the metric system, 1 inch is equal to 8 minutes, and 25.4mm in the metric system. 6 minutes=3/4 inches=20mm.4 minutes=1/2 inches=15mm.

Also, remember that pipelines are calculated based on their inner diameter, but the threads of pipelines are calculated based on their pitch diameter, represented by the diameter DN. The threads are divided into metric M and imperial G, and pipeline threads are generally in imperial system with a thread angle of 55 degrees The metric system is 60 degrees.
