Metal hose with fittings nipple with male thread
Relevance
Metal hose with fittings "nipple (male thread)" series ST040 in the form of stainless steel bellows hose in a stainless steel double or single layer braid is used to connect the pipeline transport of gaseous or liquid media under high / low pressure, as well as in vacuum systems. Such metal hose is intended for compensation of axial, thermal expansions as well as for absorption of vibrations and oscillations of pipelines. All threaded elements of metal hose with fittings "nipple (external thread)" series ST040 are made of stainless steel or alloy steel grade St. 20. Depending on the requirements to the elements of the connection of pipelines, threaded connections are made with internal (union nut) thread or with external thread. Metal hoses are leak-tight, flexible, corrugated piping that are covered with built-in end fittings and braids. They are used to compensate for temperature, as well as assembly deformations of pipelines.

Note
- The indicated working pressure (P oper), is based on a temperature of 20 °C.
- Metal hoses with end fittings are made of a flexible one-piece, the length of which is 25 m.
Application
Metal hoses can be connected to any elements of the pipelines, are used for transportation of different media, including explosive and aggressive, in almost all industries. Metal hoses come in different sizes: diameter 6 - 350 mm, length 2500 - 6000 mm. In order to increase protection against mechanical damage and durability, bellows (bellows) of the metal hose has protection in the form of a metal mesh braid. The main criterion for increasing the service life of metal hoses is their professional installation and proper operation in the pipeline.
Operating conditions of sealed metal hose with "external thread (nipple)" series ST040:
- Working medium temperature in the range of -260 ° C + 800 ° C;
- P (operating) - operating pressure - 1,6 bar - 190 bar;
- Operating media: air, steam, water, gases, aggressive media, petroleum products;
Operating conditions of metal hose with threaded joints depend on the material.
