Types of concrete pipes
Feather pipe, also known as reinforced concrete pipe, is a unique product used in communication installations that is made from concrete with exceptional strength. A pipeline is formed when two pieces are joined together, and sealants, bitumen stumps, and rubber sealing rings are used to guarantee the pipeline’s tightness.
Different kinds of pipes exist. They are therefore separated into two shapes: square and round, and into two diameters: small (50-110 cm) and large (110-550 cm). Product classification is based on how well the products dock with each other: bells and falsis. Pipes vary from one another in terms of length and embedded materials as well.
Pressure
Pumping stations generate pressure, which is used to transfer liquids through pressure pipes. These are typically high-throughput sewage and water supply pipelines.
Some goods are referred to as low-jaid because they can only tolerate very little pressure, up to 10 atm. Submerged structures are moved to 20 atm, and high pressure is reached up to 25 atm.
The M400 brand cement and higher are used for their release. Steel or polymers can be used for pressure pipe cores. Even after being distilled from aggressive liquids that can reach temperatures of up to +400 degrees, they do not degrade.
Underwear
These pipes have pressure-free, independent fluid flow primarily because of the slope that is installed right away when the track is being built. This category includes groundwater systems and pipelines for storm and residential sewers. They are composed of regular and quickly modified Portland cement, slag Portland cement, and concrete that has corrosion- and sulfate-resistant additives added.
Crucial! Serious loads cannot be supported by underwear pipes.

Production of concrete pipes
Moisture- and bio-resistant concrete brands are used in product production. Vibration pressing, either with or without reinforcement using reinforcing rods B1 and BP1, is the primary method of production. Depending on the exact kind of equipment, the average pipe creation time is only three to twelve minutes.
The steps in the production process are as follows:
- cleansing and lubrication of the form;
- installation on the bottom of iron rods in the form of a frame;
- contracting of rods;
- moving the structure to a centrifuga;
- slow supply of solution, filling all voids;
- prophet in a special chamber for a set of strength;
- disassembly of the form;
- Transportation of the finished pipe to the warehouse.
Because they are strong, long-lasting, and reasonably priced, concrete pipes are a dependable option for sewage systems and other infrastructure requirements. They are perfect for a variety of applications because they are long-lasting, corrosion-resistant, and able to support large loads. Ensuring their performance requires proper installation, which includes actions like cautious trench preparation, precise pipe alignment, and safe joint sealing. Concrete pipes can function effectively and durably in a variety of settings by adhering to these guidelines.
The most important operational characteristics
The pipe’s strength is its primary characteristic since it determines the potential depth of lay as well as the possibility of deformations during ditch laying. The pipeline won’t remove the load and won’t function as intended if the strength is decreased.
Concrete’s resistance to cracking is also considered. The product typically endures the pressure for which it is intended, with chips occurring no more than 0.2 mm.
The design of concrete pipes
Concrete pipes used to have enormous walls and bouncers installed. Modern products are made from higher-quality, more durable raw materials and are thinner as a result.
The production of pipes with a common foundation for weak soils lessens the pressure’s magnitude. Sometimes the foundation is prepared with a reverse arch, which improves pipeline efficiency, allows water to escape, and acts as a tray in the event of a leak.
Pipes with a round base of links with a diameter of 1.25–1.25 meters, a wall thickness of 14–16 centimeters, and an extra flat sole are utilized when installing on low technical category roads. The latter device has a class A2 metal grid of welded reinforcing rods that is one centimeter thick. Installing these pipes is thought to be extremely expensive because they are typically positioned beneath embankments that are up to 7 meters high.
Various methods of connection
Reinforced concrete pipes come in different types depending on the connection type.
- Fulfinial. Are used more often than others, since they are connected easily and quickly. The narrow end of one product is introduced into the expansion of another, and in the area of the junction the seal is laid.
- Falts. The docking is carried out at the expense of quarters selected on the edges – recesses, which perfectly fit the protrusions on another pipe. On top the junction of the joint is covered with concrete. The installation of such a pipeline will take more time, but the cross section will be perfectly even.
Marking and dimensions
Every concrete pipe has a label indicating its intended use. The product’s end is marked with a combination of letters and numbers. The primary categories of pipes are:
- T – cylindrical in the form of a cone with a sleeve, have a sealing ring;
- TN – for pressure systems with pumps;
- TP – pipes similar to T, but with bells;
- TB – with a stubborn loop and rubber rings;
- TBP – with the sole;
- TS – with a step surface and seals;
- TSP – with reinforced concrete sole;
- TFP – folding with seals;
- TBFP – folding with the sole;
- Then as the previous ones, only with oval holes;
- TE – with ellipsoid holes.
Furthermore, numbers are a necessary component of reinforced concrete marketing. The internal section is shown in the first, the length in decimeters is shown in the second, and the bearing capacity is shown in the third.
Some manufacturers also include the letter to indicate the walls’ permeability and resistance to various substances. As an illustration, the letter "o" signifies extremely low permeability, "p" lower, "n" normal, "p" resistance to alkalis, and "k" to acids.
The scope of concrete pipelines
Similar systems are typically used to build pipelines that are 5–10 meters long and transfer liquids with different levels of aggressiveness.
Their primary operational directions are:
- sewage for household, industrial waste;
- Magistral type collectors;
- storm sewers, systems for the removal of melt and sedimentary waters;
- highways for pumping non -aggressive liquids;
- drainage through the embankments of the road type;
- reclamation systems;
- drainage systems;
- devices for "locking" underground rivers;
- collectors under the railway tracks;
- pipelines under bridges and buildings;
- concrete miconnel for the placement of cable networks, other communications;
- systems for transporting liquid chemicals.
Advantages and disadvantages
The longevity of products made of reinforced concrete is their primary benefit. Because the basis’s material resists the effects of harmful factors, the majority of them have a lifespan of 50 to 100 years.
Other benefits of pipes are taken into account:
- slight exposure to metal elements of corrosion;
- the possibility of operation in an aggressive environment;
- excellent resistance to physical impact;
- impermeability for liquids (moisture resistance W4-W6);
- resistance to bioderation, overgrowing, decay, temperature changes, inertia on the action of many chemical reagents;
- the highest strength, resistance to destruction, cracking, bending and deformation (more effective compared to polymers);
- frost resistance from F50 to F300;
- non -combustibility, lack of risk of melting during heating;
- lack of damage due to the action of vagus currents;
- efficiency of release, short production process;
- the presence of a large range of products with a variety of technical parameters;
- ease of installation, the accuracy of the butt of individual elements;
- reducing the complexity of sealing due to rubber seals in the kit.
The products’ substantial bulk is a drawback, but because of their weight, they are able to withstand the pushing forces that eventually affect the walls during thaws, floods, and soil removal.
Speaking of which, However, under some circumstances, the internal reinforcement of the pipes may corrode, leading to the formation of growths or thinner walls.
How to choose pipes
High-quality pipes satisfy every GOST criterion in the following areas:
- Outside and inside, there are no cracks on the walls;
- The details have the necessary marking, equipped with rubber seals to ensure the tightness of the joints.
Consider the desired length, diameter, and section type when making your selection. They can only fully meet the requirements needed to complete specific tasks in this manner.
Because concrete pipes are strong and long-lasting, they are essential to sewage systems and many other applications. These pipes are perfect for long-term use because they are made to resist large loads and challenging environmental circumstances. Their ability to withstand chemical erosion and abrasion adds to their dependability when managing wastewater and other difficult jobs.
Appropriate preparation and execution are crucial for installation. To avoid settling problems in the future, it is crucial to make sure the ground is stable and sufficiently prepared. To keep the sewage system intact, it is essential to use the right bedding material and align the pipes precisely. Throughout the installation process, routine inspection can assist in spotting possible issues early on and fixing them.
Making sure the joints are properly sealed to stop leaks is a crucial part of installing concrete pipes. Depending on the particular needs of the project, a variety of jointing techniques, including mortar joints and rubber gasket joints, can be employed. While each approach has benefits of its own, the end result is always the same: a leak- and contamination-proof seal.
To sum up, concrete pipes are a dependable option for demanding applications like sewage systems. Their resilience to extreme weather, robustness, and longevity make them a great choice for long-term infrastructure projects. With the right installation techniques and close attention to detail, these pipes can offer a reliable and effective way to manage sewage and other materials.
