Premium Pipe Expansion Joints – High Pressure, For Export
- Pipe Expansion Joints (اتصال قابل انبساط) are precision-engineered sliding joints designed to accommodate over 100 mm of longitudinal movement in pipelines.
- Manufactured in Iran with stainless steel sliding surfaces, they protect pipeline components from stress caused by thermal expansion and contraction.
- These joints withstand high pressures (PN 10–63 bar) while maintaining full operational integrity in industrial and municipal systems.
- Durable materials, including ST37-2, ductile iron, NBR/EPDM gaskets, and galvanized steel fasteners, ensure long service life and minimal maintenance.
- Certified epoxy powder coatings make them corrosion-resistant and safe for potable water, making them ideal for diverse pipeline applications worldwide.
Pipe Expansion Joint – Premium Quality for Export
Pipe Expansion Joints (اتصال قابل انبساط) are precision-engineered for pipelines subjected to thermal expansion, contraction, and longitudinal movements. Manufactured by Iran, these joints are sliding-type with stainless steel sliding surfaces designed to accommodate 100+ mm longitudinal movement. This ensures protection of pipeline components and equipment from stress and potential damage.
Unlike conventional rubber or accordion joints, our expansion joints can handle high-pressure applications while maintaining full operational integrity. Their durable construction ensures reliability in both industrial and municipal pipeline systems.
