Metal hose with valve nipple with male thread
Relevance
Metal hose with fittings «nipple (male threads)» series ST040 in the form of stainless steel bellows hose stainless metal double layer or single layer braid is used to connect truboprovodov transporting gaseous or liquid media under high/low pressure and vacuum systems. Such metal hose is designed to compensate for axial thermal expansion and also to absorb vibrations and oscillations of the pipeline. All parts with external thread metal hose with fittings «nipple (male threads)» series ST040 are made of stainless steel or alloy steel brand St. 20. Depending on the requirements of the elements of accession of pipelines, threaded connections are made with internal (nut) thread or with male thread. The metal sleeve is a sealed, flexible corrugated pipes, which are covered by the built-in end fittings and braided hose. Applied to compensate temperature and Assembly deformations of pipelines.

Note
— specified operating pressure (P slave), given in accordance with the temperature of 20 °C.
— Metal hoses with end fittings are manufactured from flexible one-piece part, the length of which is 25 m.
Application
Metal hose can be connected to any of the elements of pipelines used for transportation of different environments, including explosive and aggressive, almost all industries. Metal hoses are different sizes: diameter 6 — 350mm, length 2500 — 6000 mm. In order to increase protection against mechanical damage and strength, bellows (corrugated) metal sleeve has protection in the form of a metal mesh braid. Main criteria increase the service life of the metal hoses is professional installation and proper operation of the pipeline.
