Ceramic pipes are quite common today, because they differ in excellent characteristics. They can be used to solve industrial and household issues. They are made from fired clay, which is covered with glaze during the production process. Products are characterized by high strength and an excellent degree of protection against external negative influences. Perhaps these products will suit you if, for example, you plan to lay the pipeline.
Main varieties
To date, several varieties of ceramic pipelines are known; these products can be used in different fields. Among other pipes, it should be distinguished:
- sewer;
- drainage;
- for heat supply and water supply;
- for gas boilers and chimney furnaces.
Application area
Ceramic pipes have found their wide distribution today. They can be used for industrial and domestic needs. Sewer, for example, are highly durable, insensitive to temperature fluctuations, do not corrode, and are almost indifferent to chemicals.
Such pipes are easy to lay, which is further facilitated by modern technology. The described products are also used for the installation of drainage systems. They are complemented by holes and have high strength. Drain pipes are flexible, as they are equipped with special couplings.
Ceramic pipes are also used for microtunneling. This variety of products has an impressive diameter, high tightness and strength. Pipes are used not only for the installation of the sewer system, but also for heat, water and gas supply. Ceramic pipes are quite widely used for chimneys of boilers and furnaces, and are made of heat-resistant ceramics. The assembly is carried out from different sections, the products are covered with expanded clay shell or mirror steel, which is resistant to rust.
Production technology
Ceramic pipes are made by burning clay and other inorganic materials. Quartz sand is sometimes added to the main raw material, which makes the products durable and extends their life. The manufacturing process is as follows. At the first stage, raw materials are prepared - the molding material is made from grinding clay.
The next step is the molding of products; in this process, screw vertical vacuum presses are used, which make it possible to form a bell and cut pipes. Products are dried and fired in tunnel kilns. Ceramic pipes in the next step are dipped into the glaze, during which the pool is used.
Technology features: pipe cutting
Grinding machines are usually used for pipeline cutting, with high-strength diamond disks acting as their working element. Ceramic pipes can be cut into pieces using pipe cutters specifically designed for such products.
When using standard pipe cutters, you can cut a pipeline whose diameter varies from 50 to 150 mm. First, fixation is made on the pipeline, and after it is pulled together with a ratchet mechanism. Sharp rollers cut into the surface and the material bursts in those places where the greatest stress occurs.
Main advantages
The described products have proven themselves quite well when laying drainage and building sewer systems, as well as laying gas, water and heat supply systems. This prevalence is due to several reasons, among them:
- resistance to corrosion;
- abrasion resistance;
resistance to temperature extremes; - resistance to aggressive chemicals.
An additional advantage is the possibility of using movable couplings when laying drainage systems.
Ceramic Pipe Standards
Ceramic sewer pipe is manufactured according to state standards 286-82. After reviewing them, you can find out that special requirements are imposed on the described products. For example, the design is able to withstand pressure, the level of which is 0.2 MPa. The material is resistant to acids within 90%. Thanks to this characteristic, such pipes are most often used for the construction of pressure-free sewage systems.
The diameter can vary from 100 to 600 mm. The length of the pipe does not exceed 1500 mm, while the wall thickness can vary from 20 to 40 mm. Ceramic pipes for sewage can have a bell. Sewer pipes are mated using clay locks, special mastics or asbestos cement. The diameter of the socket inside is usually equal to a figure from 224 to 734 mm.
Drainage ceramic pipes
Ceramic drainage pipes are made of plastic clay, to which various substances are added, which contribute to improving the quality characteristics of products. In the manufacturing process, the method of molding on tape or special presses is used. Firing involves the use of an overturned flame. Pipes on the outside are coated with glaze.
If we are talking about bell-shaped products, then they have openings through which water enters. But they clog pretty quickly. Recently, the most commonly practiced production of such pipes without a bell. Ceramic couplings are used to interface elements and protect against siltation. Inside, water can enter through the joints. The diameter of ceramic pipes for drainage is equal to the limit of 25 to 250 mm. The length can be equal to 335 mm maximum, in some cases this parameter is 500 mm. Such products are made frost-resistant, so they are ready to undergo about 15 cycles of freezing and thawing.
Options for using ceramic pipes in conjunction with heating equipment
Ceramic pipes are most often used for the removal of gases, which can have different temperatures. But such products are suitable for equipment that runs on solid fuel, namely:
- corner;
- coke;
- baby;
- pellets.
Pipes are used for units on liquid fuel, as well as gas boilers and fireplaces. Some types of pipes are intended only for low-temperature boilers.
Ceramic pipe structure for furnace equipment
The ceramic tube of the furnace has a certain structure. The inner shell is made of ceramic, while the middle layer is made of a heat insulator. Stone blocks are usually used to form the outer shell.
Smoke ceramic pipes on top have elements for the accumulation of moisture and its removal. The pipe must have elements to protect it from rain and wind. The design is supplemented with elements for cleaning and technical inspection, as well as for connecting to equipment.
Why choose ceramic pipe
The main advantage of ceramic products, which form the basis of pipelines for various purposes, is the ability to undergo a sharp change in temperature. The material may be affected by chemicals that are not capable of changing the properties of the pipe.
Products are resistant to abrasion and corrosion processes. With their help, it is possible to lay systems in settlements without destroying roads and sidewalks. Drainage systems are highly flexible, and the connection of ceramic elements can be carried out even with pipes of another material.
Conclusion
A ceramic pipeline is also good because it can have a cross section of various shapes. Quite often, semicircular, round, elliptical or rectangular pipes go to work. The most common are still products with a circular cross section. At the same time, work is cheaper, and the pipeline has the necessary hydraulic characteristics and is characterized by high operational and technical qualities.
