Asbestos-cement pipe - a demanded building material

Asbestos cement is considered a valuable building material, which is obtained artificially. Technological properties of pipes made of asbestos-cement distinguish them from competitive products. When they are manufactured, basic components such as asbestos and cement are used.

The production of these products includes the mandatory use of Portland cement, which does not contain additives - M400 and M500. The manufacturing process involves mixing the fibers with cement. The first step is to form the workpiece. Then the asbestos-cement pipe is placed on the conveyor. After hardening, it is lowered into the pool, and at the final stage it is grinded. Asbestos-cement pipe is a universal product that has a number of valuable properties.

Advantages of the material:

• Resistance to rot and corrosion;
• Low thermal conductivity;
• High strength;
• No tendency to fouling;
• durability;
• reliability;
• Low cost;
• Resistance to aggressive water.

Among the shortcomings can be distinguished fragility.

Asbestos-cement pipe is of three types:

• Gas pipeline;
• Water supply;
• Sewer.

Pressure and non-pressure pipes are manufactured in the production. They have differences and are used in different industries.

Asbestos-cement pipe is non-pressure designed for outdoor piping, sewerage, chimney, fences, cable laying, as well as for drainage systems. With the help of these products, telephone cables are laid from asbestos cement. In addition, they are used as pillars for fences and in the construction of a foundation. Pressurized products are used for ventilation, gas supply, water supply, garbage disposal and reclamation.

Ways of connection

For the connection of asbestos-cement material, suitable couplings, staples, brackets are used. The most common method of joining products. Before they are connected, the coupling is heated in hot water (90-100 ° C). Then one end of the coupling is put on the already laid pipe, and the second end is fixed on the other side. On a wet ground, the clutch after the joint is recommended to be filled with hot bitumen.

The asbestos-cement pipe 100 mm in diameter has a weight of 24 kg, and its length is 3950 mm. There are products from asbestos cement with a diameter of 100 to 500 mm, with a length of 3.95-5 meters. The different diameter of the cross section depends on the area in which the construction material is used. In the design work, it is important to choose the right products.

Technical requirements for the finished product:

• Straightness of products;
• Compliance with all required standards;
• Full compliance;
• The material must be waterproof;
• All pipes are tested by hydraulic pressure.

It is strictly recommended not to replace non-pressure products with pressure ones, and vice versa! Non-pressure asbestos-cement pipes, whose price is slightly lower, allow you to save. However, it is worth considering that the gas must be supplied under pressure. If the material does not meet the specifications, an accident may occur.

The technology of production of this product is well developed. When using these products, installation costs are reduced by 50%.
