Query for thick-walled pipe specifications
I. Overview of Thick-Walled Pipes
Thick-walled pipes refer to steel pipes with a relatively thick wall in the pipeline, which have strong pressure-bearing capacity and bending strength. Thick-walled pipes are mainly used in high-pressure pipelines and in industries such as chemical, metallurgy, petroleum, and natural gas for transportation.
II. Common Specifications of Thick-Walled Pipes
The following are common specifications and models of thick-walled pipes for reference:
1. GB/T8162-2008 Seamless Structural Steel Pipes
Specification and model: 10, 20, 35, 45, Q345B, 16Mn, 27SiMn, 12Cr1MoV, 15CrMo, etc.
Wall thickness range: 1mm - 80mm
Application scope: Seamless structural steel pipes are widely used in the manufacturing of general structures and mechanical structures.
2. GB/T5310-2017 Seamless Steel Pipes for High-Pressure Boilers
Specification and model: 20G, 20MnG, 25MnG, 15MoG, 20MoG, 12Cr1MoVG, 15CrMoVG, 12Cr2MoG, 12Cr2MoWVTiB, etc.
Wall thickness range: 1.5mm - 60mm
Application scope: Seamless steel pipes for high-pressure boilers are widely used in the pipeline systems of boilers.
3. GB/T6479-2013 Seamless Steel Pipes for Petroleum Cracking
Specification and model: 10, 20, 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, 1Cr19Ni11Nb, etc.
Wall thickness range: 3mm - 45mm
Application scope: Seamless steel pipes for petroleum cracking are suitable for cracking reactors, hydrogenation reactors, and hydrogenation cracking equipment, etc.
4. GB/T14976-2012 Stainless Steel Seamless Pipes
Specification and model: 00Cr19Ni10, 0Cr18Ni9, 00Cr17Ni14Mo2, 0Cr18Ni12Mo2Ti, etc.
Wall thickness range: 1mm - 30mm
Application scope: Stainless steel seamless pipes are widely used in fields such as chemical, aviation, aerospace, nuclear energy, and food.
III. Summary
The above are the common specifications and models of thick-walled pipes. Each specification and model has its specific application and scope. When purchasing thick-walled pipes, it is necessary to select the appropriate specification and model according to the specific application and load requirements to ensure the safety performance and stable operation of the pipeline.
