What is a stainless steel pipe?
Stainless steel pipe is a tubular product made of high-quality stainless steel material, which has the advantages of corrosion resistance, high temperature resistance, and high compressive strength. According to different manufacturing processes, stainless steel pipes can be divided into
stainless steel seamless pipes and
stainless steel welded pipes. Stainless steel pipes are widely used in industries, construction, chemical industry, medical equipment and other fields, and are an important metal material. The main materials of stainless steel pipes are 304, 316, 321, etc., each material has different characteristics and applicable fields.
Why recommend stainless steel pipes?
1. Hygiene and health Stainless steel is a healthy material that can be implanted in the human body, so for water supply pipes, stainless steel pipes are good for health. After the immersion test, all indicators meet the requirements of relevant national drinking water standards. The inner wall of the stainless steel pipe is smooth, and it will not scale or be contaminated by bacteria after long-term use. There is no need to worry about the water quality being affected, and secondary pollution of water can be avoided. 2. Pay attention to material selection All raw materials are 304,
304L, 316L, 316L, which meet the requirements of JIS4305. The above grades are characterized by stable performance, high strength and low thermal expansion coefficient. 3. Durable stainless steel surface thin and dense chromium-rich oxide film makes stainless steel.
Advantages of stainless steel pipes
High temperature and high pressure resistance
Stainless steel can work safely for a long time at -270℃-400℃. No harmful substances will be precipitated at high or low temperatures, and the material performance is quite stable; the tensile strength of stainless steel water pipes is greater than 530N/mm, with good ductility and toughness. The high strength of stainless steel water pipes greatly reduces the possibility of water leakage under the influence of external forces, significantly reduces the leakage rate, and effectively protects and utilizes water resources.

The inner wall of the stainless steel pipe is smooth, and it will not scale or be contaminated by bacteria after long-term use.

Beautiful appearance
The surface of stainless steel is bright, shiny, and highly reflective. This can bring your project a high-end appearance that other materials cannot achieve.
Strong
Stainless steel pipes are very strong and can resist destructive elements that can destroy other types of pipes, making them ideal for applications that require high strength.
100% recyclable
When stainless steel pipes are no longer needed, they can be melted down and reconverted into other metal parts that can be used in other industries.
Economical and practical
Stainless steel has been a common material since its invention in the 20th century. Among the various materials of water pipes, the best is stainless steel water pipes. This is related to the superior properties of stainless steel, such as corrosion resistance, high strength, and strong impact resistance. Its service life can be said to be the same as the life of the building. One-time investment and lifelong benefits can be described as "once and for all".
Good mechanical properties
Thin-walled stainless steel pipes have high strength and hardness, can withstand large external forces and pressures, and have good durability and stability.
Wide range of applications: Stainless steel pipes can be widely used in cold water, hot water, drinking water, air, gas, medical gas, petroleum, chemical industry, water treatment and other pipeline systems.
Disadvantages of stainless steel pipes
Disadvantages of stainless steel water pipes - Material selection
All raw materials are graded 304, 304L, 316, and 316L, all of which meet the requirements of JIS4305. The above grades have the characteristics of stable performance, high strength, and low thermal expansion coefficient.
High price
The disadvantage of stainless steel water pipes is that they are expensive. For general home decoration, most people cannot accept their price. If we consider their health, pressure resistance, and service life, the cost of using stainless steel water pipes is still lower than that of other pipes.
Difficult processing
Stainless steel has high hardness and is difficult to process. It requires special tools and techniques, which increases the manufacturing and installation costs. For manufacturers, higher production skills and processing costs are required.
Poor thermal conductivity
Stainless steel pipes have poor thermal conductivity and dissipate heat more slowly than ordinary steel pipes, so special attention should be paid when used at high temperatures.
Difficult welding
Stainless steel pipes are heat-resistant, so it is difficult to melt the solder and form a seal. If the welding is not thorough, the pipe may leak at the joint.
Heavy weight
Stainless steel pipes are much heavier than other types of pipes, which makes them difficult to transport and install.
Limited strength
Since the wall thickness of thin-walled stainless steel pipes is relatively thin, their strength will be limited to a certain extent, so special attention should be paid when using them in some occasions that need to withstand greater pressure and external forces.
It can be seen that stainless steel pipes have the advantages of corrosion resistance, weldability, and good polishing performance, but also have the disadvantages of slightly higher prices, heavy weight, and difficult welding. But considering all factors, the advantages of stainless steel pipes are still more than the disadvantages, which is why they are widely used.
