Which is better, stainless steel pipe or plastic pipe?

Stainless steel pipes are better

Characteristics of plastic pipe;

1. The safety and durability of plastic water pipes is poor

The plastic pipe adopts hot melt connection. This connection method is not easy to control the temperature, the temperature is too low, the connection is not strong to leak; The temperature is too high, the plastic material will seriously deteriorate, brittle joints. Even if the temperature is well controlled, the plastic at the junction, after remelting, is in effect a secondary plastic, a weak point in the piping

2. Relatively low pressure,

Generally, it is only allowed to be used in the working pressure of 0.6mpa. At the same time, the linear expansion coefficient of plastic pipe is large (0.15mm/m℃), so technical measures must be taken to prevent the expansion deformation of the pipe when the pipe is installed openly or not directly buried. The joint is easy to break when conveying hot water.

3. Plastic water pipes have low sanitary performance

The plasticizer and antioxidant that must be added inside the production plastic tube are carcinogenic to the human body. It has a great impact on the kidney and liver of the human body, leading to cancer, kidney damage, damage to the human body function reconstruction system, and affect development.

4. Short service life, generally 5-15 years service life, high maintenance cost

Features of stainless steel pipe:

1. Health, material selection

Stainless steel material can be implanted into the body of the healthy material pipeline wall smooth, long-term use will not scale, not easy to be contaminated by bacteria, do not need to worry about the water quality is affected, but also to eliminate the secondary pollution of water.

Superior materials, pipe fittings are mainly made of 304(or 316) stainless steel, seal ring is made of silicone rubber, good temperature resistance.

2. Durable, energy saving and environmental protection

The service life of stainless steel water pipe can reach 100 years, almost no maintenance is needed in the life cycle, avoiding the cost and trouble of pipeline replacement, and the comprehensive use cost is low.

Stainless steel material is 100% renewable material, will not cause public harm to the environment.

3. High temperature and high pressure resistance, wide range of use

Stainless steel can work safely in the temperature of -270℃-400℃ for a long time. The tensile strength of stainless steel pipe is greater than 530 N/mm, which greatly reduces the possibility of leakage affected by external force, so that water resources can be effectively protected and utilized.

Stainless steel pipe can be widely used in cold water, hot water, drinking water, air, gas, medical gas, petroleum, chemical, water treatment and other pipeline systems.

4. Economical and practical

Long service life of stainless steel, up to 100 years, stainless steel zero maintenance, a lifetime benefit
