Water and gas pipe
Advantages of VGP pipes
These steel pipes serve as the basis for gas or water circuits. They are designed to work under high pressure, have a long service life, are more durable than pipes made of non-ferrous alloys and meet all sanitary standards. Steel pipes have an attractive appearance. they are reliable, durable, and the possibility to reuse recycled scrap further increases their profitability.
Disadvantages
The main disadvantage is the increased cost of such pipes. In addition, these pipes in plumbing systems require additional protection against corrosion.
Manufacturing .
GOST 3262−75 regulates the production of steel boiler and water and gas pipes smooth or with rolled or cut cylindrical threads. The use of steel alloys (normalize GOST: 1050−88 or 380−88. All electric-welded VGP pipes are characterized by a reinforced seam. For additional protection against corrosion, they can be galvanized. The additional galvanized coating — not less than 0.03 mm weight of galvanized pipes is 2−3%.

Application
Gas and water pipes are used as the basis for water and gas circuits, in particular in heating systems where good thermal conductivity is important. Steel pipes are used not only in domestic sanitary and sewage systems, but also in industrial gas/liquid transfer circuits under high pressure.
Supply
We supply certified steel pipes. The price is formed on the basis of European rates for ferrous metal without including additional costs. Water and boiler pipes can be additionally equipped with couplings (GOST 8944−75, GOST 8954−75, GOST 8965−75, GOST 8966−75). We can easily buy in bulk any semi-finished products for large-scale production. We provide favorable conditions for retail buyers.
