Species overview
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.
By material
All devices are divided into metal and plastic.
- Single bolt models are available in stainless steel, zinc alloy steel and brass.
- The nylon power tie is more durable and can withstand maximum 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.
Dimensions (edit)
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.
MGF clamps with two bolts have diameters - 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.
Modifications from different manufacturers, depending on the purpose, also differ in diameter:
"Robust" power clamp W4 - 36-39 mm;
Applications
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.
Installation tips
- 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 properly selected, high-tech clamp, there are usually no problems with its installation and further operation.

Peculiarities
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, malfunctioning 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.
