Description

Technical Field

[0001] The utility model relates to the technical field of drain joints, in particular to a steel-in-steel drain joint. Background Art

[0002] The trap utilizes the high strength and sealing properties of steel casing to successfully address the challenges of waterproofing and leak prevention. The steel pipe outer protective layer is strong, resistant to damage, and can withstand the upper load of the trap. To ensure a long lifespan, the steel outer casing is treated with corrosion protection, ensuring the safety of the heating pipeline and enabling safer and more widespread use in various temperature environments, making it particularly suitable for high-temperature steam pipeline projects.

[0003] Due to long-term oxidation work, a large amount of dirt is generated on the inner wall of the drain joint due to oxidation work, and there are also certain impurities in the steam. Long-term accumulation can easily cause blockage inside the drain joint, affecting the subsequent draining work.
