Product Description:
Carbon Steel Pipe - Product Overview
Carbon steel pipe is a type of steel pipe that is made from carbon steel, which is a strong and durable material. It is commonly used in various industries such as construction, oil and gas, and manufacturing. Our carbon steel pipe is available in different thicknesses, processing services, DIN standards, and lengths to meet the needs of our customers.
Thickness
Our carbon steel pipe is available in different thicknesses, ranging from SCH 10 to SCH XXS. The thickness of the pipe is an important factor to consider as it determines the strength and durability of the pipe. The thicker the pipe, the stronger it is and the higher the pressure it can withstand.
Processing Service
We offer various processing services for our carbon steel pipe to meet the specific needs of our customers. These services include cutting, bending, welding, and more. Our experienced technicians use advanced equipment to ensure the highest quality of work and precise results.
DIN Standards
Our carbon steel pipe is manufactured according to various DIN standards, including ST33, ST37, ST35.8, ST42, ST45-8, and ST52. These standards ensure that our pipes meet the required specifications and quality standards, making them reliable and suitable for various applications.
Length
We offer two options for the length of our carbon steel pipe - random length and fixed length. Random length refers to pipes with varying lengths, while fixed length refers to pipes with a specific length. This allows our customers to choose the most suitable option for their projects.
Inspection
We understand the importance of ensuring the quality of our products. That's why our carbon steel pipe undergoes party inspection before delivery. This means that a third-party inspection company will inspect our pipes to ensure they meet the required standards and specifications.
Overall, our carbon steel pipe is a high-quality and versatile product that is suitable for a wide range of applications. With various thicknesses, processing services, DIN standards, and length options, we are confident that we can meet the specific needs of our customers. Our commitment to quality and reliability is reflected in our products and services, making us a trusted supplier of carbon steel pipe.
Carbon Seamless Steel Pipe / Tube
Seamless carbon steel pipes are made of steel ingots or solid billets through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The raw material of carbon steel pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls.
