The GB/T 18984 standard pertains to cold-drawn preservative seamless steel tubes designed for low-temperature-service piping. These tubes are specifically formulated to handle the challenges presented by low-temperature environments, ensuring maximum performance and reliability.
The material used in the production of these seamless steel tubes is of superior quality, adhering to the strict standards set out by the GB/T 18984 specification. These tubes are manufactured using a cold drawing process, which imparts exceptional dimensional accuracy and a smooth surface finish.
The cold-drawn preservative seamless steel tubes defined by GB/T 18984 possess several key features that make them suitable for low-temperature-service piping applications. These features include:
The chemical composition of the GB/T 18984 cold-drawn preservative seamless steel tubes is as follows:
| Element | Chemical Composition (% by weight) |
|---|---|
| Carbon (C) | 0.12 max |
| Silicon (Si) | 0.20 - 0.35 |
| Manganese (Mn) | 0.40 - 0.90 |
| Phosphorus (P) | 0.035 max |
| Sulfur (S) | 0.035 max |
| Nickel (Ni) | 0.30 max |
| Chromium (Cr) | 0.30 max |
| Copper (Cu) | 0.25 max |
| Vanadium (V) | 0.03 max |
| Aluminum (Al) | 0.02 max |
The mechanical properties of the GB/T 18984 cold-drawn preservative seamless steel tubes are as follows:
| Property | Mechanical Requirements |
|---|---|
| Tensile Strength (MPa) | min 490 |
| Yield Strength (MPa) | min 325 |
| Elongation (%) | min 22 |
| Impact Toughness (J) | min 27 at -50°C |
The GB/T 18984 standard covers several steel grades suitable for low-temperature-service piping. These grades include:
The GB/T 18984 cold-drawn preservative seamless steel tubes find extensive applications in low-temperature-service piping systems across various industries. These tubes are commonly used in the transport of liquids and gases in environments where low temperatures might compromise the integrity of standard piping materials. Some notable application areas include:
While the GB/T 18984 standard provides a comprehensive range of grades ensuring reliability and performance, in some instances, alternative grades may be suitable for specific applications. Some possible alternative grades to consider include:
