Product Description:
Product Overview: Carbon Steel Pipe
The carbon steel pipe is a type of structural steel tubing that is widely used in various industries for its strength and durability. It is a metal pipe made from carbon steel, which contains a high amount of carbon and other alloying elements such as manganese, silicon, and copper. Carbon steel pipes are available in both seamless and welded forms, making them suitable for different applications.
Processing Service
Our carbon steel pipe can undergo various processing services to meet the specific requirements of our customers. These services include cutting, bending, welding, and more. Our team of experienced professionals ensures that each pipe is processed with precision and accuracy, delivering high-quality products to our clients.
Process
Our carbon steel pipe is available in two different processes: hot rolled and cold rolled. Hot rolled steel pipe is formed by heating the steel above its recrystallization temperature and then rolling it into its desired shape. This process results in a stronger and more ductile pipe. On the other hand, cold rolled steel pipe is formed by rolling the steel at room temperature, which makes it stronger and smoother than hot rolled steel.
Tolerance
Our carbon steel pipe has a tolerance of ±6%, which ensures that the dimensions and specifications of each pipe are within the acceptable range. This tolerance level is maintained throughout the manufacturing process, ensuring consistent and accurate products for our customers.
Thickness
Our carbon steel pipe is available in a wide range of thicknesses, ranging from SCH 10 to SCH XXS. This allows our customers to choose the most suitable thickness for their specific application. Our pipes are also available in different lengths to meet the needs of various projects.
Commodity
Our carbon steel pipe is a commodity that is highly sought after in the market for its versatility and strength. It is widely used in various industries, including oil and gas, construction, and automotive, for its excellent mechanical properties and cost-effectiveness. The demand for carbon steel pipe is expected to continue to grow in the future, making it a valuable commodity in the market.
Carbon Seamless Steel Pipe / Tube
Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.
Hot rolled seamless steel pipe deformation process can be summarized as three stages: extension, perforation and finishing. Hot rolled seamless steel pipes is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling and hot rolled is carried out at above the recrystallization temperature of the rolling. Hot rolled seamless steel pipe can damage the refinement of the crystal grains of the steel, cast microstructure of the steel ingot and eliminate the defects of the microstructure so that the the steel organization compacting, improves the mechanical properties. This improvement is reflected in the rolling direction so that the steel is no longer at a certain extent isotropic; pouring the formation of bubbles, cracks and osteoporosis, under high pressure and temperature can also be welded together.
Hot Rolled Steel Pipes (Seamless Tube) in different size, specifications, grades & thickness as per the client's requirements. The range offered by tubes is available as per the international & national standard and can be available from us at affordable prices. These pipes are used in various application industry like shipbuilding, power plants, oil and gas, automotive, sugar mills and distilleries, cement and construction industries etc.
