Specification

SEODescription

The Φ25-28mm Expansion Sleeve integrates an 8x150mm Flange Connector, designed for thermal expansion and vibration compensation in industrial piping systems. This component supports direct connections to pipelines with 25-28mm diameters via its durable Φ25-28mm Expansion Joint, accommodating axial and lateral movement. The 8x150mm Flange Connector features eight bolt holes spaced 150mm apart, ensuring secure mounting to standard flanges. Operating within a temperature range of -40°C to +150°C and pressure up to 16 bar, it is ideal for HVAC, chemical processing, and oil/gas applications. Constructed from corrosion-resistant stainless steel, it offers high durability and minimal maintenance. However, its fixed size limits adaptability to non-standard pipe dimensions, and extreme pressure fluctuations may reduce lifespan. Compatible with common industrial flange standards (DIN, ANSI), it simplifies retrofitting in existing systems.

SEOQandA_Product

question:What's the correct installation procedure for Φ25-28 Ordinary expansion 8*150?
answer:Drill 8mm hole, clean debris, insert bolt, tighten nut to expand sleeve securely.
question:Why does the expansion bolt loosen over time?
answer:Ensure hole depth ≥150mm, tighten nut properly to activate expansion mechanism fully.
question:Can it be used in cracked concrete?
answer:No, use chemical anchors for cracked substrates; ordinary expansion bolts require solid material.
question:How to remove a stuck expansion bolt?
answer:Hammer bolt head to collapse sleeve, then extract with pliers or drill out carefully.
question:What load capacity does 8*150 expansion bolt have?
answer:Check manufacturer specs; typical shear/tension capacities vary by base material and installation quality.
