Galvanized pipe is used to create a wide variety of systems. Structures transport gas or liquid. Products resist corrosion and have increased strength. A special coating improves product performance and has a long service life.

Product features

Metal products are divided into two categories: classic GOST 1050 and improved GOST 9567-75. Indicators correspond to operational characteristics and are produced in accordance with regulations. The structures are hollow zinc-coated hardware. The alloy protects the metal from destruction, high pressure, and environmental influences.

Main advantages:

  • resistance to blows and increased pressure;
  • resistance to temperature extremes;
  • high tension level;
  • resistance to ultraviolet light;
  • good tightness;
  • environmental Safety;
  • with prolonged heating does not change in size.

Galvanized pipe application

Steel-rolling modifications have a variety of applications. Metal products are installed in residential areas, on the territories of industrial enterprises, in government agencies. Steel structures contain a safe amount of alloying material (5 mg / l). With an uninterrupted supply of water, they do not emit a dangerous dose.

Areas of use:

  • laying the pipeline in an open area (underground);
  • production of heating mains;
  • manufacturing of heating circuits;
  • fire extinguishing systems;
  • autonomous water supply using wells.

The daily intake of zinc for humans is 10-15 mg. If the concentration exceeds 5 mg, the taste of drinking water will "knit" the tongue. Outwardly, the liquid will begin to give off an opalescent shade - for wells this is the norm. There is not enough water exchange inside. Carbon dioxide can worsen the condition of the water.

Manufacturing

Hollow hardware is produced by the welded method. The quality of the seam is checked with special equipment. Products are galvanized in two ways.

The electrochemical method is performed by immersing the workpiece in a saline solution. The supply of current deposits the electrochemical cells on the surface.

Hot-dip galvanizing involves dipping a semi-finished product into molten zinc.

Manufacturing methods:

  1. The rolled sheet rolls are cut into narrow strips and welded together.
  2. The connected workpiece is unwound from the drum and is rolled into a cylinder using rollers.
  3. Electric arc method using inert gas.
  4. Finished cylindrical tech. the product is fed to the calibration rollers. Products are cleaned of debris and slag.

How to choose and where to buy a galvanized pipe

You should buy products from trusted companies. High-quality steel products are distinguished by increased strength characteristics and low levels of alloying substances. The buyer should pay attention to the throughput, working pressure and the cost of the product. The domestic water supply system has a cross section of 20 mm. The dimensions of the walls are relative to the internal pressure.

  1. Standard and lightweight (2.4 MPa).
  2. Reinforced (3.1 MPa).

You can buy a galvanized pipe at any specialized store. The product is of high quality and meets international standards. Special items are connected with flanges, or welded with tungsten electrodes.

In the factory, VGP systems are used. Production is characterized by increased demands on the environment.

Zinc plating increases the resistance of the metal, improves performance. The rolled products are cast using state standards and regulations. Protection of gas and water supply systems has proven itself in many areas of activity. With the right approach, the structures will last from 15 to 20 years.
