1mm 2mm High Quality 201 304 316 316L 410 430 Stainless Steel Pipe SS Tube

Short Description:

Stainless steel is an iron alloy that is resistant to rust and corrosion. It contains at least 11% chromium. Stainless steel’s corrosion resistance comes from chromium, which forms a passive film that protects the material and repairs itself in the presence of oxygen.

Its cleanability, strength and corrosion resistance have led to the use of stainless steel in pharmaceutical and food processing plants.

Different types of stainless steel are marked with AISI three-digit numbers, and the ISO 15510 standard lists the chemical composition of stainless steels specified in existing ISO, ASTM, EN, JIS and GB standards in a useful interchange table.

Stainless Steel Pipe Surface Finish

Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel bars can have different types.

There are many types of surface treatments for stainless steel pipe, each with its own unique characteristics and advantages.

One of the most common types of surface treatment for stainless steel pipe is the 2B treatment. This surface treatment is achieved by cold rolling the stainless steel sheet and then annealing it. The resulting surface has a smooth, matte finish, ideal for applications where aesthetics are not a primary concern.

Another popular finish for stainless steel pipe is the brushed finish. This finish is achieved by using a wire brush to create vertical or horizontal lines on the surface of the stainless steel pipe. Brushed finishes are often used in applications where aesthetics are a key factor, such as architectural or decorative applications. In addition to 2B and brushed surface treatment, stainless steel pipes also have other types of surface treatment, such as BA surface treatment and mirror surface treatment.

The BA finish is achieved by bright annealing the stainless steel, resulting in a highly reflective surface finish. The mirror effect is achieved by polishing the stainless steel surface to a high gloss, resulting in a mirror-like appearance.

The choice of surface finish for stainless steel tubing depends on several factors such as the application, environment, and desired aesthetics. For example, a 2B finish might be suitable for industrial applications where aesthetics are not a critical factor, while a brushed or mirrored finish might be suitable for architectural or decorative applications. In conclusion, the surface finish of stainless steel pipe is an important factor affecting its performance and durability.

Different surface treatments offer different properties and benefits depending on the application and desired aesthetics. Stainless steel tubing remains a popular material in a variety of industries, and its surface finish plays a vital role in its success.

Process of Production

Main production process: round steel → re-inspection → peeling → blanking → centering → heating → perforation → pickling → flat head → inspection and grinding → cold rolling (cold drawing) → degreasing → heat treatment → straightening → pipe cutting (fixed-to-length) )→pickling/passivation→finished product inspection (eddy current, ultrasonic, water pressure)→packaging and storage.

The first step in the production of stainless steel pipes is the selection of raw materials. Stainless steel consists of iron, chromium, and varying amounts of other metals such as nickel, molybdenum, or titanium. It is important to choose high-quality raw materials to ensure the best quality and characteristics of the finished product.

Once the raw material is selected, the next step in the production process is to melt the steel in a furnace. The molten steel is then poured into a mold to make a solidified billet.

The billet is then sent to a hot rolling mill where it is formed into the desired shape. The hot rolled steel is then subjected to further heat treatments, such as annealing or quenching, to improve its properties. Annealing involves heating steel to high temperatures and then cooling it slowly to make it softer and more ductile. Quenching involves rapidly cooling steel to temper it and make it stronger.

The next step in production is machining. Stainless steel tubing is machined to its final shape, size and length using a variety of tools including lathes, milling machines and drills.

The machining process may also involve removing any surface imperfections such as roughness or burrs. After the machining process, the stainless steel pipes are cleaned to remove any contamination before being sent for inspection. This is a critical step in ensuring that the finished product meets the required specifications and quality standards.

The testing process includes pressure testing, magnetic particle testing, ultrasonic testing and other testing. Finally, the stainless steel pipe is complete and ready for shipment or installation.

Pipes can be given various surface treatments such as polishing, grinding or electropolishing to improve their appearance and corrosion resistance.

In conclusion, the production process of stainless steel pipe is complex and requires expertise and attention to detail. However, the advantages of stainless steel pipe make it a popular material in various industries. The process of selecting quality raw materials, melting, casting, rolling, heat treating, machining, inspecting and finishing results in a durable, corrosion-resistant product that can withstand harsh conditions and provide years of reliable service.
