USE
Metallic collapsible pipelines can be used not only in oil and gas industry. This pipeline has great future in the whole territory of Russia and also in the territory of countries of near and far abroad. 
 Main applications of metallic collapsible pipelines in the interests of entities and organizations engaged in economic activity of the country are:
Transportation of oil products, oil and other crude hydrocarbons for different distances (from tens to hundreds kilometers) in severe climatic conditions;
Construction of oil products supply net in regions with poor development of transport infrastructure in a short time and with minimal capital costs.
Temporary process piping of oil and gas field facilities, water and non-aggressive, low viscous processing solutions with low solids content supply to the field.
Technical coverage of stationary oil, oil products and water pipelines in case of accidents as well as their duplication in the period of reconstruction and repair.
Oil and oil products transshipment and delivery across water obstacles without preliminary area clean-up operations;
Creation of nets of  potable and service water supply, supply of water to the areas of  forest fires suppression, natural disasters, accidents, as well as to grazing lands and irrigation facilities, etc.
 In the process of pipelines laying there is a need to overcome natural and artificial barriers. 
How does it joint?
 1) A cone-end is put into a bell-end; 
 2) Lock ring is snapped in the retorted groove on the cone.
 3) When pressure increases liquid through the play space between the bell and the cone gets into a cavity formed by the sealing ring and the bell wall and puffs up the sealing ring;
 4) You can hear click, a pipe takes its place and it is ready to work under required pressure.
