GB/T 18984 Cold Drawn Preservative Seamless Steel Tubes For Low-Temperature-Service Piping

Material and Specification

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.

Key Features

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:

  1. Resilience: These tubes offer excellent resilience and toughness, allowing them to withstand extremely low temperatures without sacrificing their structural integrity.
  2. Corrosion resistance: The seamless steel tubes are designed to resist corrosion effectively, ensuring long-lasting performance and durability in arduous conditions.
  3. Superior thermal conductivity: The tubes exhibit excellent thermal conductivity, promoting efficient heat transfer in low-temperature environments.
  4. Easy installation: The seamless construction allows for easy installation, reducing downtime and labor costs during the piping process.

Chemical Composition

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

Mechanical Properties

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

Steel Grade

The GB/T 18984 standard covers several steel grades suitable for low-temperature-service piping. These grades include:

  1. 16MnDG
  2. 10MnDG
  3. 09DG
  4. 09Mn2VDG
  5. 06Ni3MoDG
  6. 06Ni9DG
