What People Mean by “Oil Rig Pipe” On an oil rig, “pipe” can refer to multiple tubular products: drill pipe, casing, tubing, or surface line pipe. When drilling, the rotating tubular that connects the surface to the bit is drill pipe—a central part of the drill string. Casing and tubing are installed in the wellbore a...
ERW vs DOM vs CDS Tubing: what actually changes—and how to choose Mechanical tubing looks deceptively simple: it’s “just a round tube.” But the manufacturing route (welded vs. welded-then-drawn vs. seamless-then-drawn) drives the things engineers and fabricators care about—dimensional control, inside surface condition...
Why Precision Tubing Matters in Glass Machinery Equipment Precision tubing for glass machinery equipment plays a decisive role in maintaining dimensional accuracy, thermal stability, and mechanical reliability across glass production lines. Unlike general-purpose mechanical tubes, these tubes operate in environments ch...
Precision steel tubes for shock absorber reservoirs are subjected to continuous internal pressure fluctuations and temperature changes during vehicle operation. Any deviation in inner diameter, roundness, or wall thickness directly affects oil volume stability and damping consistency. For this reason, reservoir tubes demand far tighter dimensional control than ordinary mechanical tubing.
Jiangsu Suao Metal Product Co., Ltd. specializes in high-precision cold drawn steel tubes, making dimensional stability a core manufacturing focus. With integrated cold drawing, straightening, and finishing lines, Suao ensures that reservoir tubes maintain consistent geometry throughout their full length, supporting reliable shock absorber performance in long-term service.
Cold drawn tubes for shock absorber reservoirs offer superior mechanical consistency compared to hot-rolled alternatives. The cold drawing process refines the steel grain structure, increases yield strength, and improves surface finish—key factors when tubes are exposed to repeated pressure cycles.
At Jiangsu Suao Metal Product Co., Ltd., cold drawing is combined with controlled heat treatment to balance strength and ductility. This approach allows reservoir tubes to withstand internal pressure without becoming overly brittle, reducing the risk of cracking during extreme driving conditions.
| Manufacturing Step | Contribution to Reservoir Tube Performance |
| Cold Drawing | Enhances dimensional accuracy and improves pressure-bearing capability. |
| Heat Treatment | Relieves internal stress and stabilizes mechanical properties. |
| Straightening | Ensures uniform alignment for downstream welding and assembly. |
Shock absorber reservoirs are directly exposed to hydraulic oil, making internal surface quality a critical factor. Surface defects or contamination can accelerate oil degradation and increase wear on internal components. Therefore, reservoir tubes require controlled surface roughness and strict cleanliness standards.
Jiangsu Suao Metal Product Co., Ltd. integrates finishing and surface treatment into its production workflow, allowing reservoir tubes to meet hydraulic system cleanliness expectations. These capabilities support stable damping behavior and reduce the risk of premature shock absorber failure.
Shock absorber manufacturers require consistent tube quality across large production volumes to maintain uniform vehicle performance. Variations between batches can lead to damping imbalance and increased quality risks during assembly.
With two production facilities covering over 36,000 square meters, more than 200 employees, and an annual output exceeding 50,000 tons, Jiangsu Suao Metal Product Co., Ltd. is structured to support stable, repeatable supply. Its integrated inspection and production systems help ensure that precision steel tubes for shock absorber reservoirs meet consistent standards across global automotive and industrial markets.
