Stainless steel water supply pipe
Category: Other pipeline
Description
Product Introduction
Stainless steel water pipes are the best materials for direct drinking water delivery. They have a very low leakage rate, which helps save precious water resources.
In the event of an earthquake, the water supply system may be damaged, but the stainless steel pipe system remains intact. Additionally, compared to copper pipes, stainless steel pipes have better water flow and do not corrode under high flow rates. Their insulation properties are also 24 times better than those of copper pipes.
Product Features
1. Sanitary and Healthy
The inner wall of stainless steel pipes is smooth, preventing dirt accumulation and bacterial contamination over long-term use, ensuring that water quality is not affected and eliminating secondary pollution.
2. Green and Environmentally Friendly
Stainless steel pipes contain no harmful substances and do not cause secondary pollution to water sources. They are 100% recyclable and do not exhibit any oxygen permeability, making them green and oxygen-free pipes.
3. Durable
The thin and dense chromium-rich oxide film on the surface of stainless steel provides excellent corrosion resistance in all water qualities, including soft water, even when buried underground.
Field corrosion test data shows that the lifespan of stainless steel water pipes can reach up to 100 years, requiring almost no maintenance during their lifecycle, thus avoiding the costs and troubles of pipe replacement and reducing overall usage costs.
4. High Temperature and High Pressure Resistance
They can be safely used within a temperature range of -40℃ to 150℃, with high strength and good safety. Whether in high or low temperatures, they do not release harmful substances, and their material properties are quite stable.
5. High Strength
The tensile strength of stainless steel water pipes is greater than 530 N/mm, with good ductility and toughness. The high strength of stainless steel pipes significantly reduces the likelihood of leakage due to external forces, effectively protecting and utilizing water resources.
6. Energy Saving and Consumption Reduction
The inner wall of stainless steel pipes is smooth, resulting in very low water resistance, which reduces pressure loss and lowers transportation costs. The thermal conductivity is low, being 1/25 that of copper pipes and 1/4 that of carbon steel pipes, greatly reducing thermal energy loss during hot water transportation.
7. Wide Range of Applications
Stainless steel pipes can be widely used in cold water, hot water, drinking purified water, air, gas, medical gases, petroleum, chemical industries, water treatment systems, etc.
Connection Method
Crimp connection - divided into single crimp and double crimp. Double crimp is the most stable connection method. It uses radial contraction force (hydraulic pliers) to secure fittings onto the pipe and achieves a sealing effect through O-ring seals. It is easy to operate with good sealing performance and is non-removable.
Product Applications
Stainless steel water pipes are mainly used in mid-to-high-end buildings. For example, five-star hotels, high-end residential areas, villas, office buildings, hospitals, direct drinking water projects, pump rooms, rooftop solar hot water pipes, etc.
Stainless steel pipes made from material grade 316 can also be used in industrial transport pipelines for petroleum, chemicals, medical applications, food industries, coastal facilities, and seawater production equipment.
