Abstract

The invention relates to a system of plastic pipes and fittings, which system is equipped with an anti-freeze protection system to prevent the formation of ice inside the pipe network and ensure the continuous and smooth operation of the network. The system includes the plastic pipes (1) and fittings which can be pre-insulated in factory (4), the self-regulated heated cables (2) placed on the surface of the main pipe (1) and the thermostat having a temperature sensor to which the heated cables (2) are connected for the system to be adjusted.

Description

DESCRIPTION

SYSTEM OF PLASTIC PIPES AND FITTINGS

EQUIPPED WITH ANTI-FREEZE SYSTEM

PROTECTION

The present invention concerns the addition of an antifreeze detection system to a network of plastic pipes, with the aim of ensuring the continuous and smooth operation of the networks.

The term anti-icing system is used to describe the system that can apply energy in the form of heat to a network of plastic pipes, insulated or not, so as to prevent the formation of ice inside the network. The formation of ice can alter the smooth flow inside the pipes, but also cause the network to fail.

Plastic pipes have a huge application nowadays because of their properties, but also because of their easy installation. They are used with great success in water supply, sewage, heating, cooling and air conditioning networks. In addition to classic plastic piping systems, there are now factory insulated pipe and fittings systems with multiple benefits for facilities.

However, in periods of very low ambient temperature, especially during winter, the large drop in temperature can cause ice to form inside the plastic pipes. This results in the blockage of the pipe and in the worst case its failure, with the appearance of a leak. Fixing is time consuming and expensive for the installer.

It is thus an object of the present invention to advantageously address the aforementioned disadvantages and shortcomings of the prior art by proposing an antifreeze protection system for plastic pipes and fittings thereof.

An advantage of the invention is that the anti-freeze protection system is an affordable, easy-to-install and reliable solution for the protection of plastic pipes, insulated or not, at low temperatures.

A further advantage is that this particular system is a safe solution for the installer, aiming at smooth operation of the pipes for many years.

In addition, with this particular system the smooth flow of the network is ensured, even in extreme weather conditions.

A further advantage offered by the anti-freeze protection system for pipes and fittings is that it avoids unforeseen repair costs, while at the same time the scope of application increases.

These and other objects, features and advantages of the invention will become apparent in the following detailed description.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will become apparent to those skilled in the art by reference to the accompanying drawing, in which it is illustrated in an illustrative, non-limiting manner.

In Fig. 1, the system of plastic pipes and fittings, which is equipped with an anti-freeze protection system, is depicted in a three-dimensional representation, in a cross-section so that its individual parts can be seen.

DETAILED DESCRIPTION OF PREFERRED APPLICATION

Referring now to the accompanying drawing we will describe exemplary applications of the plastic pipe system with the antifreeze system.

The new system of plastic pipes and fittings consists of the main pipe (1), Fig. 1, pre-insulated with insulation (4) or not, and one or more self-regulating heated cables (2) to reduce energy consumption, which are installed at the factory on the outer surface of the main tube (1) in a specific arrangement. To ensure maximum performance, aluminum tape (3) is used as a substrate, but also to place the heated wire (2) on the main tube (1). The aluminum tape (3) has a double-sided tape with which it sticks onto the tube (1). After placing the heated cable (2) another aluminum tape (3) is placed over them, effectively enclosing the cable (2). Each plastic tube (1) or fitting has at the beginning and at the end cable terminations (5) to connect to the next tube (1) or the next fitting, so as to create a single cable line. The connections between the pieces of the network are made, either with special connection boxes, or with metal connections and heat-shrinkable tubes. The self-regulating heated cable (2) ends in a thermostat with a temperature sensor and from there the operator has the possibility of adjustments.

It should be noted here that the description of the invention was made with reference to illustrative examples of application, to which it is not limited. Consequently, any change or modification in terms of shape, dimensions, morphology, materials used and construction and assembly components, as long as they do not constitute a new inventive step and do not contribute to the technical development of what is already known, are considered included in the aims and objectives of the present invention as is summarized in the following claims.

A system of plastic pipes and fittings equipped with an antifreeze protection system, consisting of a main pipe (1) insulated with insulation (4) or not, with self-regulating heated cables (2), characterized in that the self-regulating heated cables (2) are located between of aluminum tape (3) that is pasted to the tube (1) with double-sided tape. 2. A system of plastic pipes and fittings equipped with an antifreeze protection system, according to claim 1, characterized in that the self-regulating heating cables (2) of each pipe (1) have terminations (5) for connection to the next pipe (1). 3. A system of plastic pipes and fittings equipped with an antifreeze protection system, according to claim 1, characterized in that one of the self-regulating heated cables (2) ends in a thermostat with a temperature sensor.
