Is pure copper used by water pipe fittings?

Metal, usually brass, used to make plumbing fittings. Brass is the alloy that is composed by copper and zinc place, brass has stronger wear resistance and hardness, its physical performance is proved to be suitable for connecting tube of inside and outside machine of manufacture valve, conduit, air conditioning and radiator to wait.

However, pure copper is not suitable for pipe fittings due to its relatively soft texture. Because of its good conductivity and ductility, it is suitable for making wires and other materials. In appearance, brass has a yellowish color, while pure copper has a reddish-purple color.

Is the thicker the wall of a water pipe, the better it will withstand pressure?

The compressive strength of water pipe is closely related to the thickness of the pipe wall. If the same raw material or similar raw materials are used, the thicker the wall, the stronger the compressive strength.

The SDR coefficient of the pipe, which means the standard size ratio, is the ratio between the nominal outer diameter and nominal wall thickness of the pipe, and is an important parameter to determine the ability of the pipe to withstand internal pressure.SDR6 level pipes are recommended for decoration, that is, the wall thickness of 6 pipes is 4.2mm standard, and the wall thickness of 4 pipes is 3.4mm standard. However, the compressive resistance of different pipeline products can not be judged only by the wall thickness, and the characteristics of the raw material itself need to be considered.

About the problem of conduit specification, how to choose?

The choice of indoor pipeline specification, basically see the specification that enters door conduit. Domestic enter door conduit is commonly 25mm specification, namely commonly known 6 cent is in charge. Received indoor conduit specification, in principle should be less than or equal to enter a conduit specification, according to the usage habit of different area and the size of door model and how many of outlet, of most house decorate choice 25mm 6 in charge and 20mm 4 in charge, can satisfy use demand.

What do different industry standards mean?

Every country and region, can use some standards to regulate the development of relevant industries. In PPR pipeline industry, we usually have EN/DIN/GB standards. EN represents the European Union standard, DIN represents the German standard, and GB represents the Chinese national standard.
