In modern hydraulic systems, pipelines act as the "blood vessels" for transmitting power and control. Their quality directly determines the reliability and service life of the entire system. Thanks to their outstanding performance characteristics, precision seamless steel tubes have become the irreplaceable and ideal choice for hydraulic system pipelines. What are the specific advantages of this special type of tubing? This article provides an in-depth analysis of the technical reasons why hydraulic systems must use precision seamless steel tubes and introduces solutions from professional suppliers.

Excellent Sealing Performance Ensures System Stability

The working pressure of hydraulic systems is typically as high as 20-40 MPa. Any minor leakage can lead to a drop in system pressure, affecting the normal operation of equipment. Precision seamless steel tubes are manufactured using an integral rolling process, resulting in a tube body completely free of welds. This fundamentally eliminates potential leakage hazards that could occur at weld seams. Their uniform and dense metallic structure ensures the pipeline maintains perfect sealing integrity even under high-pressure environments.

Compared to traditional welded tubes, precision seamless steel tubes have a smooth and flat inner wall, with a surface roughness that can achieve Ra ≤ 0.8μm. This superior surface quality significantly reduces fluid flow resistance and improves the transmission efficiency of the system. Furthermore, the smooth inner wall minimizes the adhesion of particulate matter, helping to maintain the cleanliness of the hydraulic oil and extend the system's service life.

Superior Pressure-Bearing Capacity Ensures Operational Safety

During operation, hydraulic systems not only withstand stable high pressure but also cope with pressure fluctuations and shock loads. Precision seamless steel tubes possess uniform mechanical properties and a good combination of strength and toughness, enabling them to withstand higher internal pressure and external loads. Through precise chemical composition control and heat treatment processes, their yield strength can reach above 345 MPa, and their tensile strength exceeds 500 MPa.

The isotropic nature of precision seamless steel tubes gives them consistent mechanical properties in all directions, which is particularly important for hydraulic pipelines subjected to complex stresses. In contrast, welded tubes have performance variations in the weld zone, making them prone to fatigue cracks under alternating loads, which becomes a safety hazard for the system.

High Dimensional Accuracy Facilitates Installation and Maintenance

The installation of hydraulic system pipelines requires extremely high dimensional accuracy, as any deviation can lead to leakage at connection points or stress concentration. The outer diameter tolerance of precision seamless steel tubes can be controlled within ±0.05mm, and the wall thickness uniformity can be within ±5%. This high-precision dimensional control ensures the accurate installation of the pipeline system.

The precision seamless steel tubes produced by Changzhou Tenjan Steel Tube Co., Ltd. utilize advanced cold-drawing processes and precision straightening technology, allowing straightness to be controlled within 0.5mm/m, greatly reducing installation difficulty. Simultaneously, the precise dimensions also facilitate subsequent maintenance and component replacement, minimizing downtime.

Reliable Corrosion Resistance Extends Service Life

Hydraulic systems operate in complex and varying environments, where pipelines may face challenges such as humidity and corrosive media. Precision seamless steel tubes can be made from different materials, such as carbon steel, alloy steel, or stainless steel, based on the application environment, and their corrosion resistance can be further enhanced through surface treatment processes.

Through strict material selection and process control, Changzhou Tenjan Steel Tube Co., Ltd. ensures that every precision seamless steel tube has uniform chemical composition and microstructure, avoiding the occurrence of localized corrosion. The company also provides surface treatment services such as phosphating and galvanizing to meet anti-corrosion requirements for different usage environments.
