A gas carpet is a part necessary when laying both a ground and an underground gas main network. This small manhole with a rim performs a protective function against external contamination and, at the same time, provides access for repairs and control measurements during the operation of the gas pipeline.
How to properly use a gas carpet?
In Moscow, as in other Russian cities, the main method of laying the gas pipeline is underground. Gas carpets are used at the exit points of the most important units and close various valves, gate valves and condensate collectors. The gas carpet provides not only protection against damage to pipeline fittings, ingress of various contaminants and condensate, but also prevents unauthorized entry into the system, as well as gas leakage. The above means that it ensures the safety of conducting gas to the end consumer.
Carpets can be made from various materials. The choice of the part of the required size will depend on where this device will be used, and on what diameter pipe it will be installed. Today, there are polymer-sand, steel and cast-iron gas carpets. All of them will differ in their quality characteristics have their own advantages and disadvantages.
Cast iron gas carpet: technical specifications
Carpet gas: advantages
The polymer-sand gas carpet is distinguished by its lightness, corrosion resistance, strength, frost resistance and durability. It is made from a special mixture of sand and polyethylene, taken in approximately equal proportions. Steel and cast iron carpets are also very durable, but they cannot boast of high resistance to moisture, negative temperatures and other atmospheric influences. Over time, the material of such a carpet may undergo corrosive changes, which may threaten the safety of using the gas pipeline. This is why gas carpets need regular inspection, occasional painting, and replacement when necessary.
Polymer sand caps require less maintenance and effort. In addition, products made of steel and cast iron are much heavier than their polymer counterparts. Gradually accessories from modern materials replacing more familiar cast-iron and steel counterparts. Although, for the protection of gas valves and fittings, cast-iron carpets are most often used. Gas carpets also differ in their dimensions - height and diameter, and can be used on pipes of various diameters.
Gas carpet installation
The gas carpet is installed on a concrete pad or on a base made of a more modern polymer material, in the case of a polymer-sand carpet. At the beginning, a discharge pipe is installed, after which the base itself is mounted on the compacted soil. Experts recommend installing the outlet tube in the center of the carpet so that it is perpendicular to its base. All the space around it is covered with sandy soil. Remember that the distance between the outlet and the cover of the carpet must be at least 10 cm. After installation, the location of the gas carpet is marked with a wall marker, which is fixed at a height of at least 2 meters.
In addition to gas carpets of various sizes, you can purchase any accessories for gas equipment, as well as accessories for household gas appliances and spare parts included in the internal structure of a gas boiler, gas stove etc.
The cast-iron plumbing carpet is an anti-vandal special hatch (carpet) - it is reliable and convenient protective device on any modern water supply system, as well as an underground gas pipeline.
Carpets for modern cast-iron valves are necessary for more reliable protection of certain parts of mounted stems from possible contamination or accidental damage.
Consider the main advantages of the carpets used, they are as follows:
- high-quality special technological casting made of durable cast iron;
- resistance to many possible damages;
The product is used for septic tanks and some treatment facilities. This type of water carpet provides convenient and easy access to the mandatory control, also measuring, some shut-off, including control valves, which are available on the pipeline, at the same time, it reliably protects pipes / fittings from unplanned penetration and damage.
- The color of the carpet we offer is black;
- It is made of rugged cast iron;
- The water carpet consists of a special body, a cover, as well as an axis.
What is a carpet on a modern sewer?
The water carpet is a cylindrical protective dome-rim with a special cover, made of high-quality reliable cast iron. This product is produced in a wide variety of required standard sizes, which allows it to be successfully used on modern pipelines of various diameters.
By the way, carpets specially cast from SCH-20 gray cast iron are also used on gas pipelines; there are also modern products made of durable and lightweight polymer sand mixture.

Why do you need a gas carpet?
A gas carpet is a special device that is used in the process of laying a gas main. Such elements are necessary both when laying a gas pipeline underground and on the surface. Externally, the carpet is a hatch, which can have a different diameter, and the element also has a special rim. The carpet is made of durable, anti-nuclear and durable materials, since it must provide reliable protection for the entire system. Most often, this element is installed in places where condensate is collected, as well as not far from the location of the valve or valves. The gas carpet ensures reliable transportation of gas by pipeline to the end consumer.
Insofar as gas carpet can be made from different material and have a different diameter, respectively, its cost can also be different. You can choose a certain type of element based on your own preferences and goals, but it is very important that the installation process is carried out correctly. This is due to the fact that the carpet must be securely installed, since further operation depends on the strength of its installation. Often, the installation of such an element occurs in a specially prepared concrete pad of the desired diameter. If a person opted for a carpet made of sand-polymer material, then the base can also be made of polymer.
Direct purpose of the gas carpet
Regardless of the diameter and material of manufacture, the carpet performs certain functions:
- prevents unauthorized access to the gas pipeline;
- provides anti-corrosion protection for the system;
- makes it possible to conveniently carry out maintenance and repair of the system;
- makes it possible to carry out underground communications.
The gas carpet has thick and durable walls and a special shut-off cover, thanks to which outsiders cannot penetrate to the shut-off valves and the entire gas system for the purpose of hurting her. In addition, no carpet pollution and foreign objects could easily get inside the system, which could also provoke a breakdown of the gas pipeline and its components. The second function of the carpet is to protect the components of the gas pipeline from corrosion. This is also a very important function, since under the influence of moisture or precipitation, the gas pipeline equipment can oxidize and, accordingly, become unusable. The carpet, in turn, completely prevents the occurrence of such situations.
Of course, any gas pipeline needs periodic maintenance or repair. But to perform such work, specialists need to get to the locations of stop valves and valves. Access to the elements of the gas pipeline is provided precisely through the gas carpet, moreover, thanks to it, work is carried out faster and more conveniently. Since the construction of the gas pipeline leaves underground space, which is very often used for various communications, specialists need unhindered access to the underground space. It is the carpet that provides such access and makes it possible to carry out communications underground, without prior preparation.

What is a carpet on a gas pipeline
The gas carpet is a cylindrical protective dome-rim with a cover, made of steel, cast iron, polymer-sand mixture or polymeric materials. The product is produced in various sizes, which allows it to be used on pipelines of different diameters. Gas pipelines use modern products made of polymer sand mixture by hot pressing. According to the characteristics, the polymer-sand carpet on the gas pipeline almost completely repeats the cast-iron product, but it is much easier and easier to install, frost-resistant, and durable. Installation of these products is carried out on a concrete base (cushion).
The high strength of the products allows them to withstand significant loads (up to 25 and 15 tons, respectively). In most cases, installation is carried out on a concrete base.
Complies with the requirements of regulatory documents: GOST 12.2.003-91
To protect pipeline fittings on above-ground sections of gas pipelines, polymer sand, polymer sand and sewer manholes are used. There is a special version of the product for gas, made from a polymer sand mixture by hot pressing.
Carpets made of polymer sand products comply with all state standards and are widely used. The parameters of the polymer sand product allow it to be used as an option for an underground or above-ground valve, protecting equipment from damage and contamination. The polymer sand mixture is durable, resistant to corrosion and temperature extremes. This model is installed on a base made of the same material.

Gas cast iron carpet large
The Power Engineering Plant specializes in the manufacture of a large gas cast-iron carpet, which is cast from cast iron GOST 1412-85 grade SCH 1412-85. The product is cast in several sizes and is a traditional means of protection
The purpose of the product is to protect the stem of shutoff valves during a wellless installation. Wellless installation of shutoff valves is a widespread modern method of arranging a locking unit on an underground pipeline of water supply networks without arranging a well. In this case, the control of the valve is carried out manually from the surface of the earth through the rod. The carpet serves as a device that prevents direct access to the stem and protects both the stem and the valves from mechanical damage.
|
Due to the small contact surface with the wheels of the transport, the cast-iron carpet transfers a significantly lower load to the surface layer of the roadway and does not cause its destruction in comparison with the cast-iron manhole. The decision to develop the product was made in response to the wishes of the operating and construction organizations involved in the field of water supply, road construction, and the creation of urban infrastructure. At the same time, European technical regulations and domestic construction experience were taken into account. As a result of the work carried out, the carpet KChV-V (D400) received mechanical characteristics significantly exceeding imported analogues and can be installed both on lawns and on all types of roads existing in Russia and abroad, including highways. |
 |
When tested in a certified center, the cast iron carpet withstood a test load applied through a 75 mm diameter punch in excess of 30 tons. The design of KChV-V (D400) allows you to change the installation height of the carpet, adapting it to changes in the surface level during roadway repairs due to the presence of threads. The thread is protected from concrete or asphalt ingress by sealing to withstand the temperature of the asphalt during installation. The groove of the cover and the reciprocal plane ensures the absence of such an unpleasant phenomenon as knocking during the passage of vehicles. Providing reliability and ease of operation, the carpet KChV-V (D400) has a rather aesthetic appearance, which can become an adornment of both the urban environment and suburban villages.
The gas carpet is equipment that is necessary during the laying and operation of the gas pipeline. This element is necessary not only for underground laying, but also for laying communications on the surface. Externally, this element looks like a hatch with a rim. Such hatches may have different diameters. The carpet presented on the gasaquatek.ru website is made from heavy-duty and reliable materials that can withstand even the strongest external influences. After all, this device performs the function of protecting the entire system. Usually the carpet is located near the place where the valves or valves are located. They are also installed in places where condensate accumulates in large quantities. The gas carpet must ensure safe and reliable transmission of gas through pipes directly to the consumer himself.
Gas carpets differ in price, as they are made from various materials. Also, the price depends on the diameter of the device. When choosing a carpet, you should be guided by the purposes for which it will be intended, as well as your preferences. The main thing is that the installation of the element is carried out in accordance with all the rules. Its reliable and solid installation plays a very important role, as its use will depend on it. Before you install the carpet, you need to prepare a concrete pad. Its diameter must correspond to the dimensions of the selected element. The base is allowed to be made of polymer. But this is allowed only if you have chosen a carpet made from sand-polymer raw materials.
Purpose of the device
Regardless of what the gas carpet is made of and what diameter it has, this element is designed to perform specific functions.
1. It must create an obstacle to any illegal access to the gas pipeline.
2. Protects the entire communication system from corrosion.
3. It is also installed for the free access of workers to the system so that they can maintain the elements of the system, as well as repair them in case of any malfunctions.
4. The cover provides the possibility of installing communications underground.
The gas wall carpet is very durable and reliable. It is equipped with a locking lid, which reliably protects not only the fittings, but the entire system as a whole from intruders. In addition, the carpet provides protection for the system from breakdowns. If it were not there, not only contaminants, but also foreign objects could freely get inside, which could lead to damage and breakage of pipes and other components of the system. Another very important function of the carpet is to provide anti-corrosion protection to the system. It protects it from moisture, precipitation and other factors that can provoke oxidation processes, which will subsequently lead to equipment failure. The presence of a carpet can completely protect the entire system from factors that can cause corrosion.
Maintenance and repair
From time to time there are situations when workers need easy access to equipment. This may be maintenance of its elements or repair in case of a breakdown. To be able to perform work, specialists need to get to the valves and locking elements. thanks to the carpet repair work run more efficiently. It is easier for specialists to work with system elements. And this means that the repair will be faster and better. Usually, when laying gas pipes underground, there is a place that is often used for laying communications. Workers should also have access to these communications. The carpet provides it to them. Communication with its help can be carried out without preliminary work.
