Description

Our company sells and accepts applications for the production of a corrugated metal hose, similar to the imported sleeve MH 231. The metal hose has the permission of Rostekhnadozor and a full set of certificates for all areas of application.

Metal hoses are produced in accordance with the European Union standards ISO 9001: 2000, DIN, TUV CE, and comply with the requirements of GOST.

The flexible part of the hose is made from a stainless steel billet by hydraulically forming corrugations.

The main types of produced corrugated metal hose:

  • with narrow corrugation;
  • with medium corrugation;
  • with wide corrugation;
  • for boilers;
  • high pressure.

 


 

By connection type:

  • for welding;
  • with blind flange;
  • with rotating flange;
  • with swivel collar flange;
  • threaded connection with fixed nipple with external thread;
  • threaded connection with a fixed sleeve with internal thread;
  • threaded connection with a rotating ball fitting, with union nut;
  • threaded connection rotatable, with seal;
  • threaded connection with a fixed coupling made of cast iron with internal thread;
  • connection with fitting, without nut.

Metal hoses are equipped with connections according to the customer's order. Connections are available in various designs and are made of various materials.

A stainless metal hose similar to MH 231 is manufactured with a diameter of 20 to 200 mm and a length of 250 to technologically possible. For manufacturing, a steel sheet with a thickness of 0.15 to 0.40 mm is used.
