flexible hose - Convoluted Technologies

Flexible Metal Hose 

Standard-flex and Super-flex

Convoluted Technologies stock both Standard-Flex and a Super-Flex annual corrugated metal hose, which is hydraulically formed from Stainless Steel 316 L grade strip, the inner tube shape allows the fully metal corrugated tube to bend, in un-braided configuration it could only withstand low pressures. The stainless steel 316 outer braids commonly single braid or double braiding provides the pressure capability.

Our stocked standard-flex and super-flex, convoluted metal hose and outer braiding is in stainless steel 316 grade, other grades and higher presser metal hose can be supplied on request.

A large diversity of end connections made from Stainless Steel, Carbon Steel, Copper or Brass in any possible configuration can be welded to the to the stainless steel braided hose assembly.

Product features:

  • Temperature range from -270 °C to + 816 °C
  • Different grades of stainless steel to match chemical resistant properties
  • The fully sealed corrugated metal tube allows no gas permeation through the hose wall making the product an excellent choice for industrial gasses and ultimate vacuum applications
  • Metal hose has a unlimited shelf life
  • Available in a range of sizes from 6 mm to 350 mm inside diameter
  • All metallic hose is manufactured to ISO10380 standards by carefully selected suppliers
  • The standard treaded connections are manufactured to ISO 10806 standard; Fittings for corrugated metal hose, flanges and pipe / tube components to their relevant standards custom made end fittings to customer’s special needs

 

The following additional services or certification should be taken into consideration by the customer at the time of quoting:

Hydrostatically strength / leak tested and certified to ISO 10380 standards

Nitrogen leak tested (Pneumatic test) certified to ISO 10380 standards (Maximum pressure 2 Bar)

Dye penetrant test to ISO 9712 standards level 2

Quick Vacuum test if none of the above has been performed.
