Can SYT5037-2012 spiral pipes be used in steam process pipelines with a working pressure of 1.6 MPa and temperatures below 300 degrees Celsius?
Thread Content
The scope of SYT5037-2012 \"Submerged arc welded steel pipes for general fluid conveyance pipelines\" states that these pipes are suitable for use in pipelines transporting ordinary fluids such as water, sewage, air, and heating steam; they are also applicable to steel pipes used in other fluid conveyance pipelines with similar requirements. ” ； Can Q235B spiral pipes be used in water vapor pipelines for GC-class GC2-grade process pipelines, where the design pressure is less than or equal to 1.6 MPa and the temperature is less than or equal to 300 degrees? Based on which standard specification, article, and paragraph should the judgment be made? I would appreciate guidance from experts.
It is specified in the \"Design Standards for Urban Heating Pipeline Networks\" CJJ34-2022
