The Φ48-51 expansion sleeve integrates with the Ordinary expansion 8x120 system, designed as an 8x120 mechanical anchor for robust structural fastening applications. This assembly features a standardized 8x120 mm anchor rod paired with a Φ48-51 mm expansion sleeve, supporting axial loads up to 45 kN and shear forces of 30 kN. Compatible with concrete, masonry, and steel substrates, it operates within -30°C to +80°C, ideal for construction, infrastructure, and heavy machinery industries. The sleeve's tapered design ensures uniform radial expansion for secure grip, while corrosion-resistant zinc-nickel coating enhances durability. Installation requires a 51 mm drill hole and torque-controlled tightening. Advantages include high load capacity and vibration resistance; limitations involve precise hole tolerance requirements and specialized installation tools. No electrical interfaces are integrated, focusing purely on mechanical anchoring solutions.

SEOQandA_Product

question:Difficulty in achieving proper expansion during installation?
answer:Verify tool pressure capacity matches spec; Use calibrated torque tools and check material hardness compliance.
question:Expansion tube slips post-installation?
answer:Clean mating surfaces thoroughly; Ensure tube OD/parent pipe ID tolerance within 0.3mm before expansion.
question:Premature material fatigue observed?
answer:Confirm operating pressure
question:Leakage at expanded joint interface?
answer:Inspect sealing surface for tool marks; Re-expand with 120mm minimum insertion depth maintained.
question:Inconsistent expansion profile along length?
answer:Verify mandrel alignment; Use progressive expansion technique with 3-stage pressure sequencing.
