The stratified layer is resistant to atmospheric, acid, alkali and other media corrosion, has no tendency to intergranular corrosion, and can meet the requirements of corrosion resistance of the structure and the corrosive medium; the base layer can meet the structural requirements for rigidity and weldability. Can save a lot of stainless steel and reduce structural costs.
Mainly used in the chemical, petroleum, pharmaceutical, food, seawater desalination, nuclear industry and other departments to manufacture corrosion-resistant general containers, pressure vessels and other equipment.
Stainless steel pipes are hollow, long, round steel tubes known for their excellent corrosion resistance, high-temperature tolerance, and pressure resistance. They find extensive applications in various industries such as petroleum, chemicals, medicine, food, light manufacturing, machinery, instrumentation, and more. They are used for transporting fluids, structural components, and mechanical parts.
Stainless steel composite pipes, on the other hand, are a newer material created by bonding two different metals: stainless steel and carbon structural steel, using a non-destructive pressure process. These composite pipes combine the corrosion resistance and wear resistance of stainless steel with the attractive appearance, bending strength, and impact resistance of carbon steel. Due to their pleasing aesthetics and cost-effectiveness, they are widely used in applications like bridge railings, decorative elements, vehicle accessories, conveyor rollers, textile machinery components, and more. Stainless steel composite pipes are typically manufactured using advanced equipment, technology, and computer-controlled automated production lines.
As awareness of stainless steel composite pipes grows, their range of applications is expanding. They are increasingly used in urban infrastructure, light construction projects, streetlight poles, overpasses, highway guardrails, pedestrian walkways, billboard structures, station shelters, vehicle and shipbuilding industries, medical equipment, steel furniture, and various other fields. However, it's important to note that stainless steel pipes are still essential in high-demand environments where corrosion resistance, high-temperature resistance, and pressure resistance are critical, and in such cases, composite pipes may not be a direct replacement for stainless steel pipes.

Stainless Steel Composite Pipes are highly valued for their excellent corrosion resistance, wear resistance, and heat resistance, as well as their attractive and luxurious appearance. They find wide-ranging applications across various sectors of the national economy. However, due to limited domestic resources, the demand for stainless steel in our country heavily relies on imports, resulting in higher prices and constraints on its widespread use.
Carbon steel pipes, particularly those made from Q-series carbon structural steel, are known for their high bending strength, good impact resistance, fatigue resistance, and cost-effectiveness. They serve as fundamental materials in the construction of the national economy. However, carbon steel is prone to rusting as it contains iron, a metal that reacts with oxygen in the atmosphere. This susceptibility to corrosion leads to significant economic losses, estimated in the hundreds of billions of yuan annually, due to the expenses associated with corrosion prevention and the damages caused by corrosion-related accidents.
To address these challenges, there has been a major innovation in the field of composite materials through the development of stainless steel composite pipes. These pipes are produced using advanced technology that combines stainless steel and carbon steel without the need for adhesives. The result is a composite pipe that not only rectifies surface defects common in traditional steel pipes but also enhances their performance. These composite pipes offer the dual advantages of stainless steel's corrosion resistance and abrasion resistance, along with an attractive and luxurious appearance. They represent a perfect blend of aesthetics and functionality, promoting energy efficiency and cost-effectiveness. This innovation aligns with the national policy to promote the development of composite materials and has garnered attention and support from government authorities at all levels.
