BS 3059Part2 BS 3606 Carbon Steel Pipe
High Pressure Resistance: Uniform structure ensures reliable performance in hydraulic, pneumatic, and process piping systems
Excellent Dimensional Accuracy: Precise wall thickness and roundness control for seamless integration into complex assemblies
Wide Material Range: Available in carbon steel, alloy steel, and stainless steel grades including ASTM A106, A333, API 5L, and AISI 300/400 series
Superior Corrosion & Temperature Resistance: Suitable for harsh environments including chemical processing, oil & gas, and power generation
Ideal for oil and gas transportation, boiler tubes, mechanical cylinders, automotive systems, and structural components. We offer custom cutting, threading, heat treatment, and full certification compliant with international standards including ASTM, ASME, DIN, and API.
Our seamless carbon steel pipes are manufactured from high-quality carbon or alloy steel billets through hot rolling or cold drawing processes, characterized by their dense structure, high strength, and excellent pressure-bearing performance. The products feature smooth inner walls and high dimensional accuracy, making them suitable for conveying fluids, gases, or serving as mechanical structural components. They are widely used in industries such as petroleum, chemical, power, machinery manufacturing, and boiler equipment.
Our seamless steel pipe production line adopts advanced piercing and rolling technology. Starting from a circular heating furnace, round steel billets are uniformly heated before being pierced to form hollow shells. These shells are then elongated and shaped through continuous rolling mills and sized to precise final dimensions by stretch-reducing mills. The entire line is equipped with an inline heat treatment system, allowing for normalization or quenching and tempering of the pipes as required. Quality inspection procedures include online eddy current testing, ultrasonic flaw detection, hydrostatic testing, and full-dimensional inspection, ensuring that the mechanical properties, dimensional tolerances, and surface quality of every pipe fully comply with international standards such as API 5L/5CT and ASTM A106/A53.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
