Breaking Ground In Precision Engineering: Cold Drawn Seamless Tubes Manufacturers Lead Innovation

When it comes to cold drawn seamless tube manufacturers, the biggest name in today's automotive industry, which has also been for quite a few years now, is CBIES. CBIES is a China-based steel tube and precision tube manufacturing company that started its business in 2005. It is an ISO9001 and IATF16949-certified company that aims to provide pristine quality products to its customers and ensure the best industry standards for each product.
Cold drawn seamless tubes, which are also simply known as seamless tubes, have emerged as a go-to alternative for businesses that seek durability, reliability, and precision in their applications.

What is a cold drawn seamless tube?
A cold drawn seamless tube is a cylindrical product that is prepared by drawing a solid metal billet through a piercing rod to form a hollow tube that's devoid of any seams or welds. The absence of seams or welds on these tubes enhances their rigidity, structural integrity, and resistance to various stresses. The key features of such a seamless tube are mainly good impact strength, high crack resistance, low elongation, high rigidity, and better tilt deformation ability.

Process technology
CBIES has a different approach when it comes to manufacturing these seamless tubes. The cold drawn seamless tubes are manufactured by piercing hot billets and consequently rolling them which reduces their diameter and elongates them. The formed material is then passed through a die and over a mandrel plug to create an accurate size and gauge. This is the main essence of the cold drawn process.
The tensile strength of these seamless tubes is greater than 490MPa, and they have an elongation rate at an excess of 6%.
When it comes to the process flow that is incorporated by CBIES during the manufacturing of these cold drawn seamless tubes, it is notable that the raw materials are inspected thoroughly at first followed by slitting and forming. Then the formed product is carefully welded and ground, and then sized and cut with extreme precision. Finally, the formed item is put through chamfering and polishing, which gives it a high-quality finish.

CBIES advantages in this product
●The structural integrity of these seamless tubes is well maintained.
●They have higher tensile strength and hardness properties, thereby making them suitable for performance and safety-critical applications.
●These are easier to machine and, hence, make a better-looking component.
●They're quite accurate in size, with a consistent diameter and uniform thickness.
●Due to the cold drawing process, these seamless tubes have excellent micro-structure consistency and uniformity.
●The cold drawn seamless tubes have enhanced appearance and shine thanks to no weld lines and seams.

With advanced equipment and a dedicated production line, the engineers and manufacturers at CBIES try to ensure the best industry standards for each of their products. CBIES seeks to establish a greener and safer world through the employment of sustainable practices in manufacturing every product.
