The yield strength of seamless steel pipes is one of its important mechanical properties and is crucial to ensuring the safe operation of pipelines.

Under normal circumstances, when decarburization occurs on the surface of cold-drawn seamless pipes, it is because the steel wires come into contact with the air when the lead is being melted, causing decarburization and oxidation to occur at the same time.

Directly buried prefabricated insulated seamless pipe is not a certain type of steel pipe. "Directly buried prefabricated" refers to a type of steel pipe with an insulation layer and anti-corrosion prefabricated in the insulated pipe factory.

After the installation of seamless pipes is completed and the pressure test passes, purging work is generally carried out to ensure the internal cleanliness of the pipes.

When designing steam cs seamless pipe in chemical plants, in order to ensure the quality and efficiency of the design, the pipe layout should  meet the stress requirements. In addition, attention should be paid to other details. problem and avoid water hammer.

Hot-dip galvanized seamless pipes are used in most gas systems, and their specifications and quality requirements are very strict.
