ASTM A333 Gr.6 American Standard Low-temperature Seamless Steel Pipe 355.6 * 1.13 Low-temperature Seamless Pipe

Regarding ASTM A333 Gr.6 American standard low-temperature seamless steel pipe 355.6 * 11.13 low-temperature seamless pipe, the following is a detailed information and summary based on the reference article provided:

Overview:

ASTM A333 Gr.6 low-temperature seamless steel pipe is an industrial pipeline, especially suitable for -45 ℃ to -195 ℃ low-temperature pressure vessel pipelines and low-temperature heat exchanger pipelines.

Specifications:

Outer diameter: 355.6mm

Wall thickness: 11.13mm

Materials and standards:

Material: Complies with ASTM A333 Gr.6 standard, which defines the specifications and performance requirements for seamless steel pipes used at low temperatures.

Execution standards: may include GB/T18984-2003 (Chinese national standard) and ASTM A333 (American Society for Testing and Materials standard).

Application:

Mainly used in pressure vessels and heat exchanger pipelines that need to withstand low-temperature environments, such as petroleum, chemical, natural gas, and other fields.

Precautions (for welding and other processing processes):

The one-time successful welding results in better results, as the aluminum tube has a low melting point and is prone to deformation during secondary heating.

The welding rod needs to be evenly coated with flux to ensure the quality of the welding points.

The flame of the welding gun should not be too long and should be heated with a low flame to avoid melting of the aluminum tube.

After welding, it is necessary to wait for the pipe to cool down to avoid welding leakage.

The welding time should not be too long to avoid melting or thinning of the pipe wall.

Price and Supplier:

Due to market price fluctuations and supplier differences, the specific price needs to be negotiated and determined with the supplier. The price range for seamless steel pipes of similar specifications mentioned in the reference article is between 6000 yuan and 7000 yuan (the specific price may vary depending on factors such as time, region, and quantity).

Suppliers may include companies specializing in seamless steel pipes, such as Huaneng Electric Power Technology (Tianjin) Co., Ltd. and Tianjin Zhanshi Steel Sales Co., Ltd.

Other information:

The surface of the steel pipe should be smooth and free of burrs to ensure its performance and service life in low-temperature environments.

Customized processing services for steel pipes may include cutting, customized length, etc. to meet the needs of different projects.

Please note that the above information is for reference only. When purchasing, please confirm with the supplier the detailed information such as product specifications, performance, and price.
