Product Description:
Carbon Steel Tubes are high-quality steel tubes that are widely used in various industries due to their excellent properties and versatility. They are made of carbon steel, which is a type of steel that has a high carbon content, making it strong and durable. These tubes are essential in the construction, automotive, and mechanical engineering industries, among others.
Carbon Steel Tubes are available in various surface finishes, including Bright Annealed, Polished, NO.4, and 2B. The Bright Annealed finish is achieved by heating the tubes in a controlled atmosphere to eliminate impurities and create a smooth, shiny surface. The Polished finish involves using abrasive materials to remove any imperfections and create a mirror-like surface. The NO.4 finish is a brushed finish that gives the tubes a dull, textured appearance. And the 2B finish is a semi-mirror finish that is achieved by cold rolling the tubes.
Thick Wall Pipe is a type of Carbon Steel Tube that has a thicker wall than the standard pipes. This makes them suitable for high-pressure applications and can withstand harsh environments. These pipes are commonly used in the oil and gas industry, chemical processing plants, and power plants.
The wall thickness of Carbon Steel Tubes can range from 1.5mm to 30mm, depending on the specific requirements of the application. Thicker wall tubes are used for heavy-duty applications, while thinner wall tubes are suitable for lighter applications. The wall thickness also affects the strength and durability of the tubes.
Carbon Steel Tubes can be processed in various ways to meet specific requirements. These services include Bending, Punching, and Cutting. Bending involves shaping the tubes into different curves and angles, while Punching creates holes or slots in the tubes. Cutting is used to cut the tubes to the desired length. These services allow for greater flexibility and customization of the tubes.
Carbon Steel Tubes are manufactured according to various standards, including ASTM A106, ASTM A53, API 5L, DIN 1629, and DIN 17175. These standards ensure that the tubes meet specific quality and performance requirements and are suitable for their intended use. They also provide guidelines for the production, testing, and inspection of the tubes.
