Can Galvanized Pipe be Used for Drinking Water?

When decorating a new house, plumbing decoration is a very important thing, because it is related to our daily water, water is the source of life, only by drinking water regularly can we be healthy, but if the water quality is not good, it will also be closely related to our life . Therefore, we must ensure the health of water sources in order to ensure our health. Therefore, we must pay special attention to the decoration of water pipes, otherwise it will cause very bad effects.

Since the tap water we usually use reaches every household through pipes, the choice of pipes is particularly important. We must pay special attention to the selection of pipelines. When we choose the right water pipe, the water will be clear and sweet. If we choose the wrong water pipe, the water will turn yellow and smell bad. This is galvanized water pipe.

Can galvanized pipe be used for drinking water?

Possible but not recommended. Galvanized steel pipes can be used as drinking water pipes, but the water must be boiled for drinking. However, after a long time of use, the lead and zinc in the galvanized pipe will precipitate into the water, and the pipe wall is prone to scale. As time goes by, the inner diameter of the pipe will become smaller and smaller, and the water pressure will become smaller and smaller, which is also harmful to health. Most drinking water pipes are now PPR pipes or stainless steel pipes, which have a long service life, are easy to install, and have no harmful substances seeping out.

Before the 1990s, galvanized pipes were basically used as drinking water pipes, and then they were replaced by aluminum-plastic pipes and PP-R pipes. In comparison, galvanized pipes mainly have the following disadvantages:

1. It is easy to rust and scale, and there will be water rust after a long time of use
2. The installation is troublesome. The galvanized pipe needs special cutting and threading tools, and the installation is very troublesome.
3. The interface is easy to leak after a long time
4. The production process of galvanized steel pipes has low efficiency, serious pollution and is not environmentally friendly.

Common application range of galvanized pipe:

Galvanized pipe is a kind of pipe whose surface is coated with zinc. Because zinc has good anti-corrosion properties, galvanized pipes can be widely used in construction, water conservancy, petrochemical, natural gas and other fields.

1. Construction field
Galvanized pipes can be used in building structures, such as stairs, guardrails, doors and windows, etc. At the same time, it can also be used for indoor water and gas pipeline facilities.

2. Water conservancy field
Because zinc has good corrosion resistance, galvanized pipes can be used in various water conservancy facilities, such as water pipelines, water treatment equipment, etc.

3. Petrochemical field
Most of the equipment in the petrochemical industry works in a corrosive environment, and the use of galvanized pipes can effectively prolong the service life of the equipment.

4. Natural gas field
The natural gas industry has very high safety requirements for pipelines, and galvanized pipes have high strength and corrosion resistance, so they can be used in natural gas pipelines.

In short, galvanized pipe has a wide range of uses. It plays an important role in construction, water conservancy, petrochemical, natural gas and other fields.
