PPR Clamp

Proper structural support of PPR piping through the use of PPR clamps is crucial to maximize service life and prevent failures in PPR piping sytem. Properly supporting PPR piping with quality PPR clamps at regular intervals is a small investment that pays dividends in system longevity, safety and acoustic performance.

PPR clamps are available in a variety of designs to suit different installation requirements:

Single Band Clamps

Single band clamps use a full circle of metal, plastic or composite material with a tightening mechanism to encircle the pipe circumference. They are the simplest and most common clamp type.

Double Band Clamps

Double band clamps consist of two halves that bolt together to encompass the pipe rather than a full ring. This allows installation without needing access to the pipe ends.

Suspended Clamps

Suspended clamps hang vertically from structural attachments and grip pipes from underneath via a saddle, U-bolt or perforated strap. They are ideal for supporting runs from ceilings or beams.

Heavy Duty Clamps

Heavy duty clamps provide additional strength for securing large diameter PPR mains. They resist vibration, expansion/contraction stresses and severe environments.

Insulated Clamps

Insulated clamps incorporate an internal foam pad or sleeve to prevent crushing or damaging pipe insulation while still securing the pipe.

When properly installed, PPR clamps fulfill several important roles:

Structural Support

Clamps provide fixed points for supporting the weight of pipes along runs to prevent sagging and overstressing joints. Proper spacing ensures adequate support.

Vibration Damping

By securing pipes firmly, clamps significantly dampen vibrations and movement that could lead to noisy water hammer, leaks and connection failures.

Thermal Expansion Allowance

Clamps anchor movement from thermal expansion and contraction to specific points, preventing excessive stresses on piping.

Earthquake Restraint

In seismically active regions, building codes require special seismic resistant PPR clamps to limit shifting and breakage during tremors.

External Impact Protection

Clamps add an extra layer of protection from impacts along high traffic zones and accidental hits that could damage unprotected pipes.

Securing Vertical Risers

Riser clamps prevent vertical PPR pipe from sliding down under the influence of gravity. They also reduce swaying.

Insulation Support

Many clamps are designed to compress insulation just enough to secure it without crushing or damaging it.

To achieve the full benefits of PPR clamps, follow these professional recommendations:

• Space clamps at intervals no greater than 32 times the pipe diameter to prevent excessive mid-span deflection
• Use double band clamps if accessibility is limited.
• Ensure clamps are compatible with pipe insulation thickness and materials.
• Position clamps approximately 2 feet from joints and fittings to avoid stress concentrations.
• Confirm clamp backing and strap materials are appropriately chosen for the environment to prevent corrosion or degradation.
• Use heavy duty clamps designed for the load requirements and diameters of large main runs.
• Carefully torque clamp bolts to the recommended specs; overtightening can crush pipes.

In summary, PPR clamps are indispensable components that provide fixed structural support, dampen vibrations, anchor thermal expansion and contraction, comply with seismic codes, protect from impacts, secure vertical runs and properly interface with insulation. Models like single band, double band, suspended, heavy duty, and insulated clamps suit different applications. Following professional recommendations for proper spacing, sizing, materials, placement and torque ensures clamps safely support PPR system integrity and prevent failures.
