Stainless steel pipe is widely used in various industries due to its strength, durability, and resistance to corrosion, heat, and pressure.
Oil and Gas Industry: Stainless steel pipes are widely used in the oil and gas industry due to their high corrosion resistance and strength. These pipelines can be used to transport crude oil, natural gas and refined petroleum. The industry also uses stainless steel pipes for drilling and extraction operations, offshore platforms and pipelines. Stainless steel pipes do not corrode quickly, which makes them useful in environments where water or other chemicals may be present.
Construction industry: Stainless steel pipes are widely used in the construction industry due to their high strength-to-weight ratio, which makes them useful for building structures. Stainless steel tubes are used in the construction of high-rise towers, bridges, tunnels and other infrastructure. As pipes, they are used in water and gas systems, heating, ventilation and air conditioning (HVAC) systems, and drainage systems.
Automobile industry: Stainless steel tubing is ideal for automotive applications due to its strength, durability, and corrosion resistance. Stainless steel exhaust systems are popular among automakers because they can withstand high temperatures and are less prone to corrosion, providing a longer service life than other materials. Stainless steel tubing is also used in fuel delivery systems, hydraulic brake lines and transmission coolers.
Food and Beverage Industry: Stainless steel pipes are widely used in the food and beverage industry because they are non-reactive with food and beverages. Stainless steel tubing will not leach chemicals that could affect the taste or smell of food. These pipes are used in equipment such as storage tanks, heat exchangers, and piping systems for liquid or gas transfer.
Manufacturing: Stainless steel tubing is used in manufacturing applications, especially in the chemical and pharmaceutical industries. These pipes are used to convey liquids or gases, which are often harmful or corrosive in nature. Additionally, stainless steel tubing is used in high-pressure applications that require high-strength, corrosion-resistant materials.

Stainless Steel Pipe Chemical Compositions
Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel bars can have different types.
The surface processing of stainless steel pipe have NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface finishes, etc.
NO.1: No. 1 surface refers to the surface obtained by heat treatment and pickling after hot rolling of the stainless steel pipe. It is to remove the black oxide scale produced during hot rolling and heat treatment by pickling or similar treatment methods. This is No. 1 surface processing. The No.1 surface is silvery white and matt. Mainly used in heat-resistant and corrosion-resistant industries that do not require surface gloss, such as alcohol industry, chemical industry and large containers.
2B: The surface of 2B is different from the 2D surface in that it is smoothed with a smooth roller, so it is brighter than the 2D surface. The surface roughness Ra value measured by the instrument is 0.1～0.5μm, which is the most common processing type. This kind of stainless steel strip surface is the most versatile, suitable for general purposes, which is widely used in the chemical, paper, petroleum, medical and other industries, and can also be used as a building curtain wall.
TR Hard Finish: TR stainless steel is also called hard steel. Its representative steel grades are 304 and 301, they are used for products that require high strength and hardness, such as railway vehicles, conveyor belts, springs and gaskets. The principle is to use the work hardening characteristics of austenitic stainless steel to increase the strength and hardness of the steel plate by cold working methods such as rolling. The hard material uses a few percent to several tens of percent of the mild rolling to replace the mild flatness of the 2B base surface, and no annealing is carried out after rolling. Therefore, the TR hard surface of the hard material is the rolled after cold rolling surface.
Rerolled Bright 2H: After the rolling process. the stainless steel pipe will be processed bright annealing. The pipe can be fast cooled by the the continuous annealing line. The traveling speed of the stainless steel pipe on the line is around 60m~80m/min. After this step, the surface finish will be 2H rerolled bright.
No.4: The surface of No. 4 is a fine polished surface finish that is brighter than the surface of No. 3. It is also obtained by polishing the stainless steel cold-rolled stainless steel pipe with 2 D or 2 B surface as the base and polishing with abrasive belt with a grain size of 150-180# Machined surface. The surface roughness Ra value measured by the instrument is 0.2～1.5μm. NO.4 surface is widely used in restaurant and kitchen equipment, medical equipment, architectural decoration, containers, etc.
HL: HL surface is commonly called hairline finish. Japanese JIS standard stipulates that 150-240# abrasive belt is used to polish the continuous hairline-like abrasive surface obtained. In China’s GB3280 standard, the regulations are rather vague. HL surface finish is mostly used for building decoration such as elevators, escalators, and facades.
No.6: The surface of No. 6 is based on the surface of No. 4 and is further polished with a Tampico brush or abrasive material with a particle size of W63 specified by GB2477 standard. This surface has a good metallic luster and soft performance. The reflection is weak and does not reflect the image. Due to this good property, it is very suitable for making building curtain walls and building fringe decorations, and also widely used as kitchen utensils.
BA: BA is the surface obtained by bright heat treatment after cold rolling. Bright heat treatment is annealing under a protective atmosphere that guarantees that the surface is not oxidized to preserve the gloss of the cold-rolled surface, and then use a high-precision smoothing roll for light leveling to improve the surface brightness. This surface is close to a mirror finish, and the surface roughness Ra value measured by the instrument is 0.05-0.1μm. BA surface has a wide range of uses and can be used as kitchen utensils, household appliances, medical equipment, auto parts and decorations.
No.8: No.8 is a mirror-finished surface with the highest reflectivity without abrasive grains. The stainless steel deep processing industry also calls as 8K plates. Generally, BA materials are used as raw materials for mirror finishing only through grinding and polishing. After mirror finishing, the surface is artistic, so it is mostly used in building entrance decoration and interior decoration.
Packaging is generally naked, steel wire binding, very strong.
If you have special requirements, you can use rust proof packaging, and more beautiful.
