Seamless carbon steel pipes are a crucial technology in the modern engineering industry, playing an indispensable role in energy transmission, chemical engineering, oil extraction, and construction. With its outstanding performance and reliability, seamless carbon steel pipes have become a critical component for efficient energy transmission.
Outstanding pressure-bearing capacity: Seamless carbon steel pipes are renowned for their exceptional strength and toughness, making them excel in the transportation of liquids and gases under high-pressure environments. Their unique manufacturing process ensures smooth and flawless internal surfaces, reducing energy loss and friction during fluid transmission, guaranteeing efficient energy transfer.
Corrosion resistance: In fields such as chemical engineering and oil extraction, corrosive media often present serious challenges. Seamless carbon steel pipes, with their excellent corrosion resistance, can operate stably in harsh environments, reducing maintenance costs and downtime, thus improving work efficiency.
Precise dimensional control: Seamless carbon steel pipes can achieve precise dimensional control during the manufacturing process, ensuring pipeline stability and reliability. This precise manufacturing not only enhances the connectivity performance of the pipelines but also reduces the risks of leaks and accidents, ensuring workplace safety.
Environmentally friendly and sustainable: With the increasing environmental consciousness, seamless carbon steel pipes demonstrate significant advantages in sustainable development. Compared to traditional materials, carbon steel has better recyclability and reusability, helping reduce resource waste and environmental impact.
Seamless pipes are derived from metal, however, they are also available with a plastic coating inside the steel pipe. In the case of seamless pipes the presence of plastic linings inside these pipes can allow pipes to have a relatively higher strength than most plastic pipes, and at the same time maintain the resistance to corrosion. There is also potential for corrosion of metal if the plastic cracks, causing the exposure of metal to fluid flow.
Seamless pipes undergo extreme forces during the manufacturing process; therefore, a thick high-pressure lubricant is applied to the surface of the pipe to prevent cracking, which can result in a defective pipe. Following this process, the pipe undergoes heat treatment in which the high pressure lubricant must be removed. The aggressive chemicals used to dissolve the solvent on the surface of the pipe can still remain as a residue long after the manufacturing process is completed and can result in corrosion. This is especially problematic in seamless pipes with thin diameter walls.
As tensile and yield strengths are related to the thickness of the pipe wall thickness, it is important that this thickness is not depleted in the slightest due to corrosion, otherwise it can result in pipe failure.
