Product Overview
As a key fixing component in the building water supply and drainage system, PPR pipe clamps are the "silent heroes" that ensure the safe and stable operation of the pipeline system. Specifically designed for PPR (Polypropylene Random Copolymer) pipes, these fittings accurately fix the position of the pipes, effectively offsetting the thermal expansion and contraction stress caused by temperature changes, and preventing pipe displacement, vibration, or sagging. In doing so, they guarantee the structural integrity of the entire water supply system.
PPR pipe clamps are widely used in various construction scenarios, including residential water supply systems, commercial building water supply and drainage projects, industrial pipeline laying, and HVAC (Heating, Ventilation, and Air Conditioning) pipeline installation. Whether for the neat arrangement of exposed pipes or the concealed fixing of embedded pipelines, PPR pipe clamps provide a reliable fastening solution, making them an indispensable accessory in modern pipeline engineering. Their design concept fully takes into account the material characteristics of PPR pipes, and through a scientific fixing method, they extend the service life of the pipeline system and reduce maintenance costs.
Product Composition
The composition of PPR pipe clamps reflects the perfect combination of materials science and engineering design, mainly consisting of the following parts:
Main Material: The main body of the pipe clamp is made of high-quality PPR (Polypropylene Random Copolymer) material. This material forms a stable amorphous region structure through the random distribution of ethylene monomers in the polypropylene molecular chain, endowing the product with excellent chemical stability and anti-aging performance. PPR material has the same thermal expansion coefficient as PPR pipes, which can avoid the problem of loose fixing caused by temperature changes.
Structural Design: According to different installation requirements, PPR pipe clamps mainly come in structural types such as U-type, saddle-type, and riding-type. U-type pipe clamps adopt an open design for quick installation; saddle-type pipe clamps achieve close contact with the pipe through an arc-shaped fitting surface, ensuring a more reliable fixing effect; riding-type pipe clamps are suitable for scenarios that require enhanced load-bearing capacity.
Accessory System: The pipe clamp is equipped with a variety of auxiliary fixing components, including expansion screws, spikes, or self-tapping screws and other metal connectors. These accessories are usually treated with anti-rust to adapt to humid environments. Some high-end products are also equipped with rubber buffer pads, which can reduce the noise caused by pipe vibration and avoid wear caused by direct contact between metal and plastic.
Specification Adaptation: The clamping part of the pipe clamp is strictly designed in accordance with the nominal outer diameter of PPR pipes. The inner wall is smooth and free of burrs, ensuring that it does not damage the pipe surface while providing sufficient clamping force.
Product Advantages
With its excellent material properties and scientific design, PPR pipe clamps exhibit advantages in multiple aspects:
Material Performance Advantages: PPR material has excellent chemical corrosion resistance, being immune to acids, alkalis, and salts in water. Unlike metal fittings, it does not rust and will not decompose harmful substances due to the influence of water quality. It can maintain structural stability within the temperature range of -10°C to 95°C and can withstand high temperatures of 110°C for a short period, fully meeting the usage requirements of hot water systems.
Ease of Installation: The installation of PPR pipe clamps does not require special tools. Whether using spikes for direct fixing or expansion screws for reinforcement, the installation can be completed quickly. Its lightweight feature reduces construction intensity, making it particularly suitable for high-altitude operations and operations in narrow spaces.
System Compatibility: It uses the same material as PPR pipes and has the same thermal expansion coefficient. It can expand and contract synchronously when the temperature changes, avoiding additional stress that may damage the pipe joints. The smooth inner wall design will not cause wear to the pipe surface, ensuring the tightness of the system.
Long-term Reliability: Under standard working conditions, the theoretical service life of PPR pipe clamps can reach more than 50 years, which matches the service life of the PPR pipe system. Its structural strength can withstand a working pressure of 10-25 bar, fully meeting the water pressure requirements of various buildings.
Environmental Protection and Sanitation: PPR material is non-toxic and odorless, containing no heavy metals, BPA, or other harmful substances. It will not release pollutants into the water and complies with drinking water hygiene standards. The product is fully recyclable, and the production process has low carbon emissions, meeting environmental protection requirements.
Economic Applicability: The initial purchase cost is lower than that of metal fittings. Moreover, due to its ultra-long service life and minimal maintenance requirements, the full-life cycle cost is significantly reduced. Compared with traditional metal pipe clamps that need to be replaced frequently, it can save a large amount of long-term maintenance costs.
Product Specifications
The specification system of PPR pipe clamps is rigorous and standardized, mainly classified based on the nominal outer diameter of the pipe and the installation method:

dn25mm (3/4 inch pipe): Corresponding to 3/4 inch pipes
dn32mm (1 inch pipe): Corresponding to 1 inch pipes
dn40mm (1.25 inch pipe): Corresponding to 1 1/4 inch pipes
Structural Type Specifications:
U-type pipe clamps: Models are usually marked by the adapted pipe diameter
Installation Method Specifications:
Exposed-installed pipe clamps: Usually with longer fixing feet or brackets
Concealed-installed pipe clamps: Compact structure, suitable for pre-embedded installation
Performance Parameters:
Operating temperature: -20°C to 95°C (110°C for short-term)
Material standards: Compliant with international standards such as EN ISO 15874 and DIN 8077/8078
The selection of PPR pipe clamp specifications needs to comprehensively consider factors such as pipe diameter, installation environment, working pressure, and temperature. It is recommended to consult professional technicians for model selection based on specific engineering requirements.
