Repair Clamps: Professional, Permanent Solutions for Pipes 

A leak, crack or burst in a pipe is not just a fault; it is an emergency that demands a quick, reliable repair to avoid downtime and loss of resources. Grupo Almagromur repair clamps are the definitive engineering solution for professionals in agricultural, industrial or water management environments. Manufactured from the highest-quality materials such as stainless steel, our clamps are not a temporary patch, but a permanent solution designed to restore the integrity of your pipes safely and durably. 

Definitive Guide to Selecting the Right Repair Clamp 

Choosing the right clamp is crucial to a successful repair. An incorrect selection compromises the watertightness and safety of the installation. Consider these key factors: 

Pipe Outside Diameter (OD): This is the most critical factor. Always measure the actual outside diameter of the pipe, not the nominal diameter, to determine the correct size. 

Pipe Material: Compatibility is essential to avoid problems such as galvanic corrosion. We offer solutions for PVC, polyethylene, steel, cast iron and asbestos cement. 

Working Pressure (Bar): Make sure the clamp has a nominal pressure equal to or greater than the maximum pressure your system withstands. 

Extent of Damage: The clamp must fully cover the damaged area. Its length should exceed that of the crack by at least 150 mm (75 mm on each side). 

Clamp and Gasket Material: Stainless steel (AISI 304 or 316) is the preferred option for its exceptional corrosion resistance. As for the gasket, NBR rubber is excellent for water and oils, while EPDM offers high weather resistance. The "waffle" gasket design guarantees a hermetic seal even on irregular surfaces. 

For quick selection, remember that for plastic pipes (PVC, PE) stainless steel with uniform tightening is recommended. On steel or cast iron pipes, passivated stainless steel is crucial to prevent corrosion, and it adapts well to rough surfaces. For asbestos cement, a clamp that distributes pressure evenly is needed and, on copper, it is important to insulate to avoid galvanic corrosion. 

Applications by Pipe Type: Solutions for Every Material 

Our clamps offer maximum versatility for the most common materials: 

Plastic Pipes (PVC, Polyethylene): They offer a secure seal without damaging the material, distributing pressure evenly. They are ideal for irrigation and drainage systems. 

Metal Pipes (Steel, Cast Iron): For pipelines subject to high pressures and corrosion, our stainless steel clamps with reinforced bolts repair everything from small pitting to serious bursts. 

Asbestos Cement Pipes: Due to the brittle nature of this material, our clamps with wide tolerance ranges and adaptable gaskets ensure a complete seal, avoiding costly replacement of sections. 

Key Advantages of Grupo Almagromur Clamps

Maximum Corrosion Resistance: Manufactured in AISI 304 or 316 stainless steel with full passivation treatment. 

Total Versatility: A single design is effective for repairing cracks, perforations and bursts on multiple pipe types. 

Guaranteed Hermetic Seal: Fitted with high-quality NBR gaskets with a "waffle" design that ensure complete watertightness even under pressure. 

Simplified Installation Process 

Repair leaks in minutes by following these steps: clean the pipe surface, place the clamp centred over the damage, tighten the bolts gradually and alternately to distribute the pressure evenly, and finish with a visual inspection to confirm the leak has been eliminated. 

Frequently Asked Questions (FAQ) 

Is the repair a temporary or permanent solution? It is a permanent solution. Our clamps are manufactured from highly durable materials to last as long as the pipe itself. 

Can I install it without shutting off the water supply? Yes. In most situations, they are designed to be installed "under pressure", allowing emergency repairs without interrupting service. 

How do I know which size of clamp to buy? The key measurement is always the outside diameter (OD) of the pipe. Measure precisely and consult the technical data sheet for our products. 

Can they repair cracks and holes? Absolutely. Their design is versatile and effective for a wide range of damage, including cracks, perforations and bursts.
