Large diameter plastic pipes are specially made plastic products with a cross section from 500 to 2400 mm, which have great rigidity. They are mainly used when laying pipelines for sewage or heating systems in industry. A large-diameter plastic pipe will soon replace all existing concrete and metal pipes.
These products can be made from materials such as:
- polyvinyl chloride;
- polyethylene;
- polybutene;
- polypropylene.
The most reliable is considered a plastic pipe of large diameter, made of polypropylene. Products made from this material are used mainly in hot and cold water supply.
By the way, a large diameter plastic pipe has its advantages, which should be noted, namely resistance to corrosion, various bursts and pressure surges and low thermal conductivity. In addition, these products are the cheapest.
But, in addition to advantages, a large-diameter plastic pipe has its certain disadvantages. This is an instability to the effects of ultraviolet radiation. It is also worth considering that when laying such pipes on open ground, insulation is necessary.
As for the installation of the specified product, it can be noted here that this process requires high rates of connection. Since the pipes have a large diameter, this often causes some difficulties. There are two mounting methods, namely detachable and one-piece.
In the first embodiment, if necessary, it is possible to disassemble some elements, for example, if a certain section of the pipe breaks.
In the second case, after welding, these segments become a single whole. This method is used exclusively in industry, which is again associated with a large diameter of the product. This type of connection is used for large pipelines that are placed at a certain level of depth. This type of mount is very reliable, durable, airtight and resistant to all kinds of influences that are aggressive in nature.
With the detachable method, a certain level of reliability is also provided. Connections are performed using various sockets and flanges, which have additional gaskets in the kit, which, in turn, have high elasticity. This method is used when installing
gravity, pressureless pipelines. Basically, this is the installation of any sewage systems. Such a bell-shaped connection is very easy to use, it can even be assembled and disassembled by hand. In addition, in such works, elements of not too large size are used.
A large diameter plastic pipe, the price of which is acceptable (for example, the cost of this product with a diameter of 1000 mm and a wall thickness of 50 mm is 7840 rubles per linear meter; if the characteristics are 2200 mm and 95 mm, respectively, it will cost 29920 rubles), is a competitive product in the sales market, due to its high quality indicators and ease of use. And also important is the fact that these materials have a good appearance, compared with other pipes, for example from metal.
