Specification

SEODescription

The Φ154-159 expansion joint is a versatile ordinary pipe fitting designed for industrial piping systems, featuring 8x70 expansion bolts for secure installation. It accommodates axial, lateral, and angular movements in pipelines, with a standard connection capacity of 1 input and 1 output port for direct integration with standard pipe sections. Operating within a temperature range of -20°C to 120°C and pressure up to 16 bar, it supports standard flange interfaces without integrated communication protocols. Compatible with carbon steel or stainless steel pipelines, this joint is widely used in chemical processing, HVAC, and water treatment industries. Key advantages include corrosion resistance, vibration dampening, and easy maintenance via the 8x70 bolt configuration. Limitations include restricted high-pressure applications and periodic bolt torque checks. Its compact design ensures compatibility with ordinary pipe fittings in tight spaces.

SEOQandA_Product

question:What causes cracking during expansion of Φ154-159 pipes?
answer:Excessive stress or incorrect temperature. Solution: Adjust expansion rate or pre-heat material.
question:Why does the expanded pipe have inconsistent diameter?
answer:Worn tooling or unstable pressure. Solution: Replace tooling or calibrate hydraulic pressure.
question:How to prevent surface scratches during expansion?
answer:Insufficient lubrication or debris. Solution: Apply high-quality lubricant and clean tools regularly.
question:What leads to premature tooling failure in 8*70 expansion?
answer:Overloading or material hardness mismatch. Solution: Use compatible tooling materials and reduce load.
question:Why does the expanded section show uneven wall thickness?
answer:Misalignment or uneven force distribution. Solution: Align pipe properly and ensure uniform pressure.
