Bellows stainless water inlet ¾
Corrosion-proof bellows pipes for water and steam are made of a sealed corrugated pipe. The corrugated metal hose (pipe) is made of polished stainless strips by tig welding. Foreign particles and impurities are not retained on the walls of the sealed metal hose. The high content of alloying metals Chromium 16-18%, Nickel 8-14% in the composition of steel strips completely exclude the possibility of corrosion and oxidation.
Flexible bellows connections for water and steam are completely harmless to human health and are suitable for contact with drinking water, which is reflected in the Sanitary and Hygienic Conclusion.
LLC "Komtsentr Strategy" produces flexible bellows line from corrosion-resistant steel of austenitic class. By design, stainless flexible liners resemble a corrugated hose or a metal hose made of a flexible corrugated pipe (ring corrugation), where brass union nuts are rolled at the edges along the sleeve (parts directly in contact with water are made of stainless steel).
The wall thickness of the stainless bellows line is at least 0.3 mm according to the specification of the standard and the manufacturer's documentation. Bellows hose for water and steam of our production is made of a flexible corrugated stainless pipe, additionally treated with a vacuum-thermal process (annealing in ovens at a temperature of 1020 - 1100 ° C according to ISO 9328-5) to make the pipe flexible and increase the authenticity of the metal, in the future it is easy fixes the shape when bending.
The connecting fittings (union nut) are connected to the pipe by flaring the ends of the pipe, without welding. The fittings are hexagon nuts with half-inch pipe threads to DIN 228/1 (female thread).
The presence of surfaces (cuts) or a turnkey hexagon at the ends of the bellows connections ensures that the sleeve does not twist during installation. The working pressure of the finished flexible bellows line is from 10 to 16 atmospheres, the working pressure will depend on the gaskets used for crimping the connections.
A protective polymer coating serves for additional insulation of the bellows hose from thermal effects (up to 120 ° C), and protects the bellows from mechanical damage, corrosive household detergents, and also insulates the bellows from contact with conductive grounded metal structures.
