製品概要

のASTM A106 グレード B シームレス炭素鋼管 is a premium-grade, high-performance pipe manufactured to the rigorous requirements of ASTM A106/A106M — the standard specification for seamless carbon steel pipe intended forhigh-temperature service. Produced from high-quality carbon steel with a seamless construction that eliminates weld seams, this pipe delivers exceptional strength, pressure integrity, and reliability in demanding high-temperature and high-pressure applications. The Grade B material offers a minimum tensile strength of 415 MPa and a minimum yield strength of 240 MPa, with a maximum operating temperature of 425°C. Available in sizes from NPS 1/8″ to 48″ (DN6 to DN1200) with wall thicknesses ranging from SCH20 to SCH160, and in standard lengths of 6.4M (21ft), 12M (39.37ft), or custom, this pipe is suitable for welding, bending, flanging, and similar forming operations. Compliant with ASME B36.10M for dimensional standards and ASME B31.3 for pressure piping design, this pipe is the trusted choice for oil & gas refineries, power plants, boiler systems, 化学処理, and high-temperature fluid transmission applications. With CE, API, およびISO 9001 認証, it ensures reliable performance in critical high-temperature service.

よくある質問

Q1: What is the difference between ASTM A106 Grade B and ASTM A53 Grade B?

あ: ASTM A106 is a standard specifically for seamless steel pipe intended for high-temperature service, with a maximum operating temperature of 425°C for Grade B. ASTM A53 covers both seamless and welded pipes suitable for general pressure applications, with an upper temperature limit of approximately 340°C. A106 is the most commonly used pipe material for process piping in refineries and petrochemical plants.

第2四半期: What are the maximum operating temperature and pressure for this seamless steel pipe?

あ: The maximum operating temperature is 425°C, and the minimum is -29°C. Pressure ratings depend on pipe diameter and wall thickness; detailed design pressure calculations are provided in ASME B31.3. Please determine the specific pressure rating based on your system design parameters.

Q3: What is the difference between seamless and welded steel pipes?

あ: Seamless steel pipes have no weld seams, offering superior pressure integrity, burst resistance, and resistance to stress corrosion cracking. Welded pipes are more cost-effective and suitable for general industrial applications. Seamless steel pipes are the preferred choice for high-pressure, high-temperature, and critical service applications.

Q4: Can this pipe be used for natural gas transmission?

あ: はい. ASTM A106 Grade B seamless steel pipe is widely used for natural gas mainlines, 支線, and compressor station piping, and it meets the requirements of API 5L for oil and gas transmission applications.

Q5: What are the surface treatment options?

あ: The standard finish is black or lightly oiled for rust prevention. Hot-dip galvanizing, black painting, clear coating, or anti-rust oil treatments are available upon request. Please select the appropriate surface treatment based on the installation environment and corrosion protection requirements.
