SOCLA Rubber Expansion Joints

SOCLA's Rubber Expansion Joints, such as the ZKB and ZKT models, are engineered to absorb expansions, contractions, oscillations, and vibrations in piping systems, thereby reducing noise and preventing the spread of electric currents. The ZKB model features galvanised steel flanges, with optional stainless steel flanges available upon request. The ZKT model comes with galvanised ductile iron union nut connections, with optional bronze connections to mitigate electrolytic risks. Both models offer optional vacuum rings for enhanced performance.

Frequently Asked Questions

What are SOCLA Rubber Expansion Joints used for?

SOCLA Rubber Expansion Joints are designed to absorb expansions, contractions, oscillations, and vibrations in piping systems. They help reduce noise, diminish hammering, and prevent the spread of electric currents.

What materials are used in SOCLA Rubber Expansion Joints?

These joints feature galvanised steel flanges and are available with EPDM or NBR rubber materials, catering to various operational requirements.

What sizes are available for SOCLA Rubber Expansion Joints?

SOCLA offers Rubber Expansion Joints in sizes ranging from DN 32 (1¼") to DN 600 (24"), accommodating a wide range of piping dimensions.

What is the maximum operating pressure for SOCLA Rubber Expansion Joints?

The permissible operating pressure varies by size and material. For instance, certain sizes can handle up to 16 bar in water applications. It's essential to consult the specific pressure/temperature diagrams for accurate information.

Can SOCLA Rubber Expansion Joints handle high temperatures?

Yes, the operating temperature depends on the material and pressure. Refer to the pressure/temperature diagrams to ensure compatibility with your system's requirements.

Are there optional features available for SOCLA Rubber Expansion Joints?

Optional features include stainless steel flanges (materials such as SS 304, 304L, 316, 316L), different drilling standards (e.g., PN25, ANSI 150), and vacuum rings. Consult SOCLA for these customizations.

How should SOCLA Rubber Expansion Joints be installed?

Proper installation involves anchoring, guiding, and, in some cases, using control rods, especially when operating pressures exceed specific values. Refer to the installation guidelines provided by SOCLA for detailed instructions.

What are the movement capabilities of SOCLA Rubber Expansion Joints?

These joints can accommodate compression, extension, lateral movement, and angular movement. The exact values depend on the joint size. For example, a DN 50 joint allows for 10mm compression and 7mm extension.

What flange standards are SOCLA Rubber Expansion Joints compatible with?

They are compatible with flanges drilled according to EN1092 standards, specifically PN10 and PN16. Other standards, such as PN25 and ANSI 150, are available upon request.

Do SOCLA Rubber Expansion Joints require maintenance?

Generally, they are designed for durability with minimal maintenance. However, regular inspections are recommended to ensure optimal performance and longevity.

Can SOCLA Rubber Expansion Joints be used in vacuum applications?

Yes, with the addition of an optional vacuum ring, these joints can be used in vacuum applications. Consult SOCLA for specific configurations suitable for such conditions.

Can SOCLA Rubber Expansion Joints be used for potable water applications?

Yes, specific models of SOCLA Rubber Expansion Joints with EPDM rubber are suitable for potable water applications. Always confirm compliance with local regulations before use.
