Product Description
| Product introduction | ||||||||||
| Pipeline pipes include seamless and welded pipes, and the pipe ends have flat ends, threaded ends and socket ends; Its connection methods are end welding, coupling connection, socket connection, etc. | ||||||||||
| Performance of pipeline: | 1. High strength: The pipeline should not only have high tensile strength and yield strength, but also have a yield ratio of 0.85-0.93. 2. High impact willfulness: High impact willfulness can meet the requirements of preventing cracking. 3. Low ductile-brittle transition temperature: harsh regions and climatic conditions require pipeline steel to have a sufficiently low ductile-brittle transition temperature. The shear area of DWTT (Falling Weight Tearing Test) has become the main index to prevent brittle failure of pipelines. Usually, the specification requires that the fracture shear area of the sample is ≥85% at the lowest operating temperature. 4. Excellent resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSCC). 5. Good weldability: Good weldability of steel is very important to ensure the integrity and welding quality of the pipeline. | |||||||||
| Purpose of pipeline pipe: | Transporting gas such as natural gas and liquid such as petroleum, such as submarine pipelines, land pipelines and petroleum refining pipelines. It has the advantages of economy, safety and uninterrupted, including seamless steel pipe and welded steel pipe, and can be divided into three types: cold and high sulfur areas and submarine laying. | |||||||||
