Clamp - plastic or metal?

Clamps are indispensable and very common fasteners, which are used in various fields of activity. These fastening accessories are most in demand in places where there are pipe and cable connections. Products are classified according to some parameters. Their most important characteristics are material and targets. The most "running" - plastic and metal appliances.

The metal screed is stronger and more durable than the plastic counterpart. But the plastic collar is cheaper. They are used for a variety of purposes: connecting hoses, pipes, wire fasteners, etc.

The plastic collar also has its advantages. It can be used for pipe joints of varying degrees of mobility. Due to the specifics of such material as plastic, the devices from it can be used for both rigid and mobile fixation of pipe joints, hoses and wires.

Plastic clamps are very profitable and practical, as their reliability is quite high, and they are cheaper than metal clamps. The more so that the plastic collar is not corroded, less susceptible to various aggressive environments and can be painted in different colors.

Clamp plastic (coupler) is very in demand in everyday life. For such an application the safety margin of plastic is quite sufficient. They are successfully used for marking, fastening and banding cables and wiring for electrical work, and also provide a very reliable attachment and make installation easy. Metal screeds are often used in critical areas where it is necessary to create a heavy-duty connection.

These devices are integral and double (in two parts). Whole products are often made of plastic, and double are also made of metal. Double ties (worm) consist of the device itself and the screw, with which you can adjust (within reasonable limits) the diameter of the connection section. This is the advantage of a double clamp. Double accessories can have one or two screws. Their parameters are similar. It all depends on the preference of the master (with which adaptation it is more customary and more convenient to work).

There are a lot of types of clamps. Each species is designed to perform certain tasks and has specific technical characteristics. For example, there are spiral clamps for reinforced hoses, power products for thick-walled hoses working with very high loads in harsh conditions, wire ties for conditions with high and constant vibration, heat resistant screeds resistant to high temperatures and others. Select the device is necessary for a specific type of connection and operation parameters. It is these data that are most important when choosing a yoke. After all, from the competent selection depends on the service life (durability) and reliability of the product.

Despite the development of new technologies, a worthy replacement for the collars has not yet been found. Today, the screeds are the most reliable and durable type of attachment.
