[Φ273]+Ordinary expansion 8*150

Φ273 steel pipe with Ordinary expansion fittings, compatible with 8x150mm steel tube. Designed for durable industrial piping connections under standard thermal expansion conditions.

Specification

SEODescription

This product is constructed with Φ273 steel pipe integrated with ordinary expansion fittings and 8x150mm steel tube components, designed for industrial piping systems requiring thermal compensation and structural flexibility. It supports direct connections to 8 input/output ports through standardized flanges or threaded interfaces, compatible with modular pipeline configurations. Operating within a pressure range of 0.8-2.5 MPa and temperature tolerance of -20°C to 120°C, it is widely applied in petrochemical, thermal power, and HVAC industries. The Φ273 steel pipe ensures high-pressure resistance, while the 8x150mm steel tube enables precise directional alignment. Advantages include durable galvanized coating, vibration dampening, and maintenance-free expansion joints. Limitations involve restricted angular compensation (±15°) and requirement for periodic bolt torque checks. Compatible with ASME B16.9 standards.
