Everything You Need to Know About Power Clamps

For connecting pipes, welding, hinged, collet or threaded fastening methods are not always suitable. In this situation, such a device as a power clamp becomes relevant. With its help, it is easy to achieve reliable fixation of the pipe with maximum sealing of the joints. In addition, the material from which the clamp is made reduces vibration in the pipeline and ensures the strength of the fastening.

Before talking about the features of the product, let's figure out what this element is, which is so necessary for the installation of pipelines for various purposes. The power clamp is a fastener in the form of rounded metal bands with a rubber coating on the inner part of the ring, wrapping and fixing the pipe with bolts.

Important characteristics of strength devices.

• High tensile strength of the steel plate, that is, the ability to tighten it as tightly as possible. The reliability of fixation depends on this.
• The ability of reinforced models to withstand critical mechanical loads, external and internal pressure, excluding deformation, damage and stretching.
• The ability to attach to any surface and material, thanks to a variety of fixing parts. The manufacture of clamps in accordance with GOST standards in a specialized production virtually eliminates rejects, and therefore, malfunction of fasteners.
• Models of increased strength are equipped with stiffening ribs with galvanic spraying, which allows them to be used when exposed to significant negative external factors.

Power models are produced mainly from high quality steel, which makes them resistant to corrosion and applicable in harsh conditions of high pressure, vacuum, large temperature differences. Such structures are considered to be durable in operation and the most durable, including tearing.

Power clamps are often used for the installation and repair of pipelines in hazardous environments.

• In industrial equipment with temperatures above +300 degrees, with a pressure of more than 1000 atmospheres, in high vacuum units, casting machines. Usually these are reinforced models made of durable steel with a protective coating of at least 10 microns.
• Articulated clamps are used in pneumatic and hydraulic systems, reinforced flexible high-pressure pipes for air and water, in mining and drilling facilities.
• Crimped metal parts are in demand for large pipes, their reinforced modifications are used for main pipelines.
• Power fasteners are preferable when installing plumbing wiring, since they guarantee a long service life of the pipeline and its tightness. One-piece power modifications with a lock, in fact, represent a complete design that is not afraid of extreme loads for thick-walled, reinforced hoses and drainage pumps.
• Many fasteners are required for use in aggressive, corrosive and chemical environments: for the manufacture of agricultural vehicles - seeders, combines, hydraulic carts. These parts are used in military equipment, for fixing exhaust pipes and in car engines.
• For air systems, lightweight but durable nylon clamps are used that are resistant to moisture.These are unique models that are also in demand for fixing gas, plumbing and water pipes in apartments, country houses and at various enterprises.

Crimp fastening clamps allow you to quickly and firmly connect pipes and hoses of different diameters, and fix the main pipeline at different heights. The wrapping element in these designs is the tape. One of the reinforced varieties of these parts, which differs in the method of fastening, is a power hinged clamp. It is easy to guess that the bolted view of the element is fastened with bolts when fixing pipes.

Basically, power mounts differ in several types.

• Reinforced worm gear clamp, used for piping and ventilation systems, necessary for sealing pipes, flexible hoses, hoses.

• Spiral, a feature of which is the rod, which makes it possible to use it in plastic, reinforced pipes with a wound inner surface.

• Spring model heavy load with a cycle of resizing, relevant in the automotive industry, resistant to rising and falling temperatures.

• Single bolt clamp, which is characterized by simplicity and ease of connection with a special layer of porous rubber seal on the inside. The product guarantees vibration reduction, tightness and no pinching of pipes if they are flexible.

All devices are divided into metal and plastic.

• Single bolt models are available in stainless steel, galvanized steel and brass alloys.
• The nylon power tie is more durable and withstands extreme loads. Polymer clamps allow you to use them for fixing polypropylene pipes, as well as for flexible air ducts when installing an air conditioner.
• Reinforced pipe clamps for the sewer system and water supply are always made of stainless steel and have increased durability.
• Bolted types of structures are almost always supplied with a rubber profile, especially if it is a plumbing system.

In GOST standards, you can find a table with standards, minimum and maximum sizes of power products, differing in their configuration and the number of bolts.

Let's get acquainted with the main parameters of the devices necessary for connecting especially complex pipe options, as well as thick-walled and reinforced pipes.

• Double bolt clamps MGF have a diameter of 30-40 mm, 40-50 mm, 50-60 mm, 55-65 mm, 65-75 mm and 75-85 mm. These designs provide uniform grip and contraction around the pipe circumference.

• MGF Standard Products produced with a diameter of 15-17 mm, 17-19 mm, 20-22 mm, 25-27 mm, 29-31 mm, 36-39 mm.

• If vibration is present, it is best to use clamps with spring and T-screw... Their sizes are 46-52 mm, 51-57 mm, 58-65 mm, 64-72 mm, 70-78 mm, 76-84 mm.

• There are also maximum diameters of fasteners designed for large pipes. In these cases, single-bolt clamps with a band width up to 30 mm can be from 240 to 252 mm, double-bolted from 240 to 250 mm, and spring models with a bolt from 184 to 192 mm.

Modifications from different manufacturers, depending on the purpose, also differ in diameter:

• "Robust" power clamp W4 - 36-39 mm;

• hinged clamp SIBRTECH - 56-59 mm.

Among modern designs for connecting pipelines, several high quality clamps can be distinguished, with advantageous characteristics.

• Power Model Norma designed for flexible hoses. A feature of the device is the ability to use it in critical conditions with significant mechanical and axial loads, high tensile and tensile strength, distribution of forces over the entire surface.

• Robust Hinged Pipe Clamp - indispensable for pipes reinforced with mesh and wire.

• Power clamp Kombi Kralle from German manufacturers - Reliable toothed mount with a rubber seal, resistant to extremely high pressures up to 10 bar. Purpose - connection of SML sewer pipes.

• MasterProf - power crimping clamps made of stainless steel worm-type, adjusting to the size of the pipes. They are used in pneumatic and hydraulic structures.

• Titan lock - power element made of stainless steel, which has a sealing ability for hoses used in manufacturing equipment and the automotive industry.

Professional advice will allow you to choose a power clamp for a specific case. When choosing, be guided by the following criteria:

• the best metal clamps are made of stainless steel;
• it is worth paying attention to the notches - they must be embossed, which means that the clamp can be used several times;
• choose designs with galvanized screws and bolts;
• a quality clamp has a stamp;
• when choosing a single-bolt fixture, it is important to check the availability of high-quality rubber and a protective coating that will ensure long-term operation of the product.

It is also important to determine the plane of the location of the part and the place of its installation.

• Modern power products are easy to install, and there is no need to go to great lengths to get a good tightening. Moreover, excessive overtightening can result in reduced product life and rapid wear.
• If a single bolt clamp is used, then it just needs to be unscrewed to the required pipe size, installed and tightened with a wrench using a screw.
• When attaching the clamp, you need to choose the correct diameter of the drill for drilling the hole.
• The pipe should only be secured using the method specified for the selected clamp.
• If standard clamps are suitable for hermetic fastening of cast iron pipes, then in high pressure areas it is better to choose reinforced gear models.
• Do not forget to securely fix the pipes themselves after tightening with the clamp. To do this, you need to think in advance about additional fasteners.

Based on practice, with a correctly selected, high-tech clamp, there are usually no problems with its installation and further operation.
