Precision Seamless Steel Pipes (Tubes)

Why choose cold drawn seamless carbon steel hydraulic pipe? The seamless structure is made by cold drawn or cold rolled process. Seamless hydraulic steel tubes design avoids the possible weaknesses of traditional welded pipes. Improving the overall strength and durability of steel tubes. It is suitable for high-pressure working environment, has strong resistance to high pressure, and prevents leakage or breakage.

Standard: Meet EN10305-1, EN10305-4, DIN2391/C, GB/T3639 standards. Available surface treatments: galvanizing, phosphating, passivation and pickling. Main materials: ST37.4, ST35, ST45, ST52, E235, E355. Sizes are available in standard sizes or customized according to your needs. Diameter OD: 4mm~60mm, wall thickness WT: 0.5mm-8mm.

Precision Seamless Steel Tubes Details

seamless galvanized steel tubes

Galvanized Steel Tubes

Zinc forms a protective film with metallic luster on the surface of the pipe, isolating oxygen and moisture. The seamless carbon steel hydraulic tubes is galvanized to improve corrosion resistance, wear resistance and extend service life.

Phosphated Steel Tubes

Phosphating is the process of forming a phosphate film on the surface of steel tubes. Phosphating allows subsequent coatings (such as paint, coatings or anti-corrosion coatings) to adhere better to the surface of hydraulic steel pipes, thereby enhancing the adhesion of the coating and improving the surface protection effect. It can also improve corrosion resistance.

Tube Assembly

Seamless carbon steel hydraulic pipes are bent and screwed into fixed components, which are widely used in hydraulic and pneumatic systems. Screwed components are mainly used for connecting and fixing hydraulic tubes, usually including accessories such as bolts, nuts, joints or pipe adapters. These components ensure a firm and stable connection between tubes and equipment.

FAQ For Carbon Seamless Steel Pipes

What Are the Advantages of Seamless Carbon Steel Hydraulic Tubes?
  • Seamless carbon steel hydraulic tubing have the characteristics of high strength, high pressure resistance, corrosion resistance, and wear resistance. Suitable for various hydraulic and pneumatic systems.
  • Outside diameter (OD):4mm~80mmm

    4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 15mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, 40mm, 42mm,45mm, 50mm, 55mm, 60mm, 70mm, 80mm

  • Wall Thickness (WT): 0.5mm-8mm.

    0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm

  • The size and length of the steel hydraulic tubing can be customized according to customer requirements.

  • Seamless steel hydraulic tubing has no welded seams. It has higher compressive strength and corrosion resistance. Welded pipe is relatively inferior in strength and durability.

  • Common surface treatments include galvanizing, phosphating, military green passivation, and coating, which help improve the corrosion resistance, adhesion and service life of steel pipes.

  • Engineering machinery, agricultural machinery, hydraulic systems of various industrial equipment, automobile pipeline systems, diesel engines, railway locomotives, aerospace, ships, wind power equipment, heat exchangers, etc.

How to Ensure the Quality of seamless Steel Hydraulic Tubing?
  • Our factory has corresponding quality certification (such as ISO). Our factory has a dedicated quality inspection team, and customers’ goods will undergo strict quality inspection. For example: roughness inspection, size inspection, flaw detection, etc.

  • Yes, we are a factory. We have 10 years of experience in hydraulic pipe export. We have rich experience in export trade.
  • Yes, we can customize the tube assembly. According to your needs, our engineers will arrange it.

  • The price of seamless carbon steel tubes is usually calculated based on the size, material, surface treatment, quantity and other factors. Bulk purchases or long-term cooperation customers can enjoy bulk discounts.

  • In hot and humid climate areas, it is recommended not to buy bright seamless cold-drawn carbon steel tubes. It is recommended to carry out galvanizing or passivation treatment and spray painting. This can improve the ability to resist oxidation and corrosion.
