Frequently Asked Questions

Everything you need to know about CHNFLEX expansion joints.

What is a pipe expansion joint?

A pipe expansion joint is a flexible element installed in a piping system to absorb thermal expansion, vibration, and misalignment. It prevents stress on pipes and equipment, extending system life and reducing maintenance.

Why do we need expansion joints?

Piping systems expand and contract due to temperature changes. Without expansion joints, this movement can cause leaks, cracks, or equipment damage. Joints provide flexibility and protect the integrity of the system.

What materials are used in CHNFLEX joints?

We use high-quality NBR, EPDM, Neoprene, and PTFE for rubber elements, with carbon steel, stainless steel, or ductile iron for flanges and reinforcements. Material selection depends on media, temperature, and pressure.

Can you customize products?

Yes, CHNFLEX offers full OEM and customization services. We can adjust size, flange type, material, pressure rating, and length to meet your exact specifications.
